-/**
- * cgltf - a single-file glTF 2.0 parser written in C99.
- *
- * Version: 1.10
- *
- * Website: https://github.com/jkuhlmann/cgltf
- *
- * Distributed under the MIT License, see notice at the end of this file.
- *
- * Building:
- * Include this file where you need the struct and function
- * declarations. Have exactly one source file where you define
- * `CGLTF_IMPLEMENTATION` before including this file to get the
- * function definitions.
- *
- * Reference:
- * `cgltf_result cgltf_parse(const cgltf_options*, const void*,
- * cgltf_size, cgltf_data**)` parses both glTF and GLB data. If
- * this function returns `cgltf_result_success`, you have to call
- * `cgltf_free()` on the created `cgltf_data*` variable.
- * Note that contents of external files for buffers and images are not
- * automatically loaded. You'll need to read these files yourself using
- * URIs in the `cgltf_data` structure.
- *
- * `cgltf_options` is the struct passed to `cgltf_parse()` to control
- * parts of the parsing process. You can use it to force the file type
- * and provide memory allocation as well as file operation callbacks.
- * Should be zero-initialized to trigger default behavior.
- *
- * `cgltf_data` is the struct allocated and filled by `cgltf_parse()`.
- * It generally mirrors the glTF format as described by the spec (see
- * https://github.com/KhronosGroup/glTF/tree/master/specification/2.0).
- *
- * `void cgltf_free(cgltf_data*)` frees the allocated `cgltf_data`
- * variable.
- *
- * `cgltf_result cgltf_load_buffers(const cgltf_options*, cgltf_data*,
- * const char* gltf_path)` can be optionally called to open and read buffer
- * files using the `FILE*` APIs. The `gltf_path` argument is the path to
- * the original glTF file, which allows the parser to resolve the path to
- * buffer files.
- *
- * `cgltf_result cgltf_load_buffer_base64(const cgltf_options* options,
- * cgltf_size size, const char* base64, void** out_data)` decodes
- * base64-encoded data content. Used internally by `cgltf_load_buffers()`.
- * This is useful when decoding data URIs in images.
- *
- * `cgltf_result cgltf_parse_file(const cgltf_options* options, const
- * char* path, cgltf_data** out_data)` can be used to open the given
- * file using `FILE*` APIs and parse the data using `cgltf_parse()`.
- *
- * `cgltf_result cgltf_validate(cgltf_data*)` can be used to do additional
- * checks to make sure the parsed glTF data is valid.
- *
- * `cgltf_node_transform_local` converts the translation / rotation / scale properties of a node
- * into a mat4.
- *
- * `cgltf_node_transform_world` calls `cgltf_node_transform_local` on every ancestor in order
- * to compute the root-to-node transformation.
- *
- * `cgltf_accessor_unpack_floats` reads in the data from an accessor, applies sparse data (if any),
- * and converts them to floating point. Assumes that `cgltf_load_buffers` has already been called.
- * By passing null for the output pointer, users can find out how many floats are required in the
- * output buffer.
- *
- * `cgltf_accessor_num_components` is a tiny utility that tells you the dimensionality of
- * a certain accessor type. This can be used before `cgltf_accessor_unpack_floats` to help allocate
- * the necessary amount of memory.
- *
- * `cgltf_accessor_read_float` reads a certain element from a non-sparse accessor and converts it to
- * floating point, assuming that `cgltf_load_buffers` has already been called. The passed-in element
- * size is the number of floats in the output buffer, which should be in the range [1, 16]. Returns
- * false if the passed-in element_size is too small, or if the accessor is sparse.
- *
- * `cgltf_accessor_read_uint` is similar to its floating-point counterpart, but limited to reading
- * vector types and does not support matrix types. The passed-in element size is the number of uints
- * in the output buffer, which should be in the range [1, 4]. Returns false if the passed-in
- * element_size is too small, or if the accessor is sparse.
- *
- * `cgltf_accessor_read_index` is similar to its floating-point counterpart, but it returns size_t
- * and only works with single-component data types.
- *
- * `cgltf_result cgltf_copy_extras_json(const cgltf_data*, const cgltf_extras*,
- * char* dest, cgltf_size* dest_size)` allows users to retrieve the "extras" data that
- * can be attached to many glTF objects (which can be arbitrary JSON data). The
- * `cgltf_extras` struct stores the offsets of the start and end of the extras JSON data
- * as it appears in the complete glTF JSON data. This function copies the extras data
- * into the provided buffer. If `dest` is NULL, the length of the data is written into
- * `dest_size`. You can then parse this data using your own JSON parser
- * or, if you've included the cgltf implementation using the integrated JSMN JSON parser.

-RELEASE NOTES - v0.12.0
-=======================
-Version 0.12.0 has breaking API changes including changes to the existing API and the removal of deprecated APIs.
-
-
-Improved Client-Defined Memory Allocation
------------------------------------------
-The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
-existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom
-allocation callbacks are specified.
-
-To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this:
-
- void* my_malloc(size_t sz, void* pUserData)
- {
- return malloc(sz);
- }
- void* my_realloc(void* p, size_t sz, void* pUserData)
- {
- return realloc(p, sz);
- }
- void my_free(void* p, void* pUserData)
- {
- free(p);
- }
-
- ...
-
- drflac_allocation_callbacks allocationCallbacks;
- allocationCallbacks.pUserData = &myData;
- allocationCallbacks.onMalloc = my_malloc;
- allocationCallbacks.onRealloc = my_realloc;
- allocationCallbacks.onFree = my_free;
- drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks);
-
-The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
-
-Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC,
-DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions.
-
-Every API that opens a drflac object now takes this extra parameter. These include the following:
-
- drflac_open()
- drflac_open_relaxed()
- drflac_open_with_metadata()
- drflac_open_with_metadata_relaxed()
- drflac_open_file()
- drflac_open_file_with_metadata()
- drflac_open_memory()
- drflac_open_memory_with_metadata()
- drflac_open_and_read_pcm_frames_s32()
- drflac_open_and_read_pcm_frames_s16()
- drflac_open_and_read_pcm_frames_f32()
- drflac_open_file_and_read_pcm_frames_s32()
- drflac_open_file_and_read_pcm_frames_s16()
- drflac_open_file_and_read_pcm_frames_f32()
- drflac_open_memory_and_read_pcm_frames_s32()
- drflac_open_memory_and_read_pcm_frames_s16()
- drflac_open_memory_and_read_pcm_frames_f32()
-
-
-
-Optimizations
--------------
-Seeking performance has been greatly improved. A new binary search based seeking algorithm has been introduced which significantly
-improves performance over the brute force method which was used when no seek table was present. Seek table based seeking also takes
-advantage of the new binary search seeking system to further improve performance there as well. Note that this depends on CRC which
-means it will be disabled when DR_FLAC_NO_CRC is used.
-
-The SSE4.1 pipeline has been cleaned up and optimized. You should see some improvements with decoding speed of 24-bit files in
-particular. 16-bit streams should also see some improvement.
-
-drflac_read_pcm_frames_s16() has been optimized. Previously this sat on top of drflac_read_pcm_frames_s32() and performed it's s32
-to s16 conversion in a second pass. This is now all done in a single pass. This includes SSE2 and ARM NEON optimized paths.
-
-A minor optimization has been implemented for drflac_read_pcm_frames_s32(). This will now use an SSE2 optimized pipeline for stereo
-channel reconstruction which is the last part of the decoding process.
-
-The ARM build has seen a few improvements. The CLZ (count leading zeroes) and REV (byte swap) instructions are now used when
-compiling with GCC and Clang which is achieved using inline assembly. The CLZ instruction requires ARM architecture version 5 at
-compile time and the REV instruction requires ARM architecture version 6.
-
-An ARM NEON optimized pipeline has been implemented. To enable this you'll need to add -mfpu=neon to the command line when compiling.
-
-
-Removed APIs
-------------
-The following APIs were deprecated in version 0.11.0 and have been completely removed in version 0.12.0:
-
- drflac_read_s32() -> drflac_read_pcm_frames_s32()
- drflac_read_s16() -> drflac_read_pcm_frames_s16()
- drflac_read_f32() -> drflac_read_pcm_frames_f32()
- drflac_seek_to_sample() -> drflac_seek_to_pcm_frame()
- drflac_open_and_decode_s32() -> drflac_open_and_read_pcm_frames_s32()
- drflac_open_and_decode_s16() -> drflac_open_and_read_pcm_frames_s16()
- drflac_open_and_decode_f32() -> drflac_open_and_read_pcm_frames_f32()
- drflac_open_and_decode_file_s32() -> drflac_open_file_and_read_pcm_frames_s32()
- drflac_open_and_decode_file_s16() -> drflac_open_file_and_read_pcm_frames_s16()
- drflac_open_and_decode_file_f32() -> drflac_open_file_and_read_pcm_frames_f32()
- drflac_open_and_decode_memory_s32() -> drflac_open_memory_and_read_pcm_frames_s32()
- drflac_open_and_decode_memory_s16() -> drflac_open_memory_and_read_pcm_frames_s16()
- drflac_open_and_decode_memory_f32() -> drflac_open_memroy_and_read_pcm_frames_f32()
-
-Prior versions of dr_flac operated on a per-sample basis whereas now it operates on PCM frames. The removed APIs all relate
-to the old per-sample APIs. You now need to use the "pcm_frame" versions.
-*/
-
-
-/*
-Introduction
-============
-dr_flac is a single file library. To use it, do something like the following in one .c file.
-
- ```c
- #define DR_FLAC_IMPLEMENTATION
- #include "dr_flac.h"
- ```
-
-You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following:
-
- ```c
- drflac* pFlac = drflac_open_file("MySong.flac", NULL);
- if (pFlac == NULL) {
- // Failed to open FLAC file
- }
-
- drflac_int32* pSamples = malloc(pFlac->totalPCMFrameCount * pFlac->channels * sizeof(drflac_int32));
- drflac_uint64 numberOfInterleavedSamplesActuallyRead = drflac_read_pcm_frames_s32(pFlac, pFlac->totalPCMFrameCount, pSamples);
- ```
-
-The drflac object represents the decoder. It is a transparent type so all the information you need, such as the number of channels and the bits per sample,
-should be directly accessible - just make sure you don't change their values. Samples are always output as interleaved signed 32-bit PCM. In the example above
-a native FLAC stream was opened, however dr_flac has seamless support for Ogg encapsulated FLAC streams as well.
-
-You do not need to decode the entire stream in one go - you just specify how many samples you'd like at any given time and the decoder will give you as many
-samples as it can, up to the amount requested. Later on when you need the next batch of samples, just call it again. Example:
-
- ```c
- while (drflac_read_pcm_frames_s32(pFlac, chunkSizeInPCMFrames, pChunkSamples) > 0) {
- do_something();
- }
- ```
-
-You can seek to a specific PCM frame with `drflac_seek_to_pcm_frame()`.
-
-If you just want to quickly decode an entire FLAC file in one go you can do something like this:
-
- ```c
- unsigned int channels;
- unsigned int sampleRate;
- drflac_uint64 totalPCMFrameCount;
- drflac_int32* pSampleData = drflac_open_file_and_read_pcm_frames_s32("MySong.flac", &channels, &sampleRate, &totalPCMFrameCount, NULL);
- if (pSampleData == NULL) {
- // Failed to open and decode FLAC file.
- }
-
- ...
-
- drflac_free(pSampleData, NULL);
- ```
-
-You can read samples as signed 16-bit integer and 32-bit floating-point PCM with the *_s16() and *_f32() family of APIs respectively, but note that these
-should be considered lossy.
-
-
-If you need access to metadata (album art, etc.), use `drflac_open_with_metadata()`, `drflac_open_file_with_metdata()` or `drflac_open_memory_with_metadata()`.
-The rationale for keeping these APIs separate is that they're slightly slower than the normal versions and also just a little bit harder to use. dr_flac
-reports metadata to the application through the use of a callback, and every metadata block is reported before `drflac_open_with_metdata()` returns.
-
-The main opening APIs (`drflac_open()`, etc.) will fail if the header is not present. The presents a problem in certain scenarios such as broadcast style
-streams or internet radio where the header may not be present because the user has started playback mid-stream. To handle this, use the relaxed APIs:
-
- `drflac_open_relaxed()`
- `drflac_open_with_metadata_relaxed()`
-
-It is not recommended to use these APIs for file based streams because a missing header would usually indicate a corrupt or perverse file. In addition, these
-APIs can take a long time to initialize because they may need to spend a lot of time finding the first frame.
-
-
-
-Build Options
-=============
-#define these options before including this file.
-
-#define DR_FLAC_NO_STDIO
- Disable `drflac_open_file()` and family.
-
-#define DR_FLAC_NO_OGG
- Disables support for Ogg/FLAC streams.
-
-#define DR_FLAC_BUFFER_SIZE <number>
- Defines the size of the internal buffer to store data from onRead(). This buffer is used to reduce the number of calls back to the client for more data.
- Larger values means more memory, but better performance. My tests show diminishing returns after about 4KB (which is the default). Consider reducing this if
- you have a very efficient implementation of onRead(), or increase it if it's very inefficient. Must be a multiple of 8.
-
-#define DR_FLAC_NO_CRC
- Disables CRC checks. This will offer a performance boost when CRC is unnecessary. This will disable binary search seeking. When seeking, the seek table will
- be used if available. Otherwise the seek will be performed using brute force.
-
-#define DR_FLAC_NO_SIMD
- Disables SIMD optimizations (SSE on x86/x64 architectures, NEON on ARM architectures). Use this if you are having compatibility issues with your compiler.
-
-
-
-Notes
-=====
-- dr_flac does not support changing the sample rate nor channel count mid stream.
-- dr_flac is not thread-safe, but its APIs can be called from any thread so long as you do your own synchronization.
-- When using Ogg encapsulation, a corrupted metadata block will result in `drflac_open_with_metadata()` and `drflac_open()` returning inconsistent samples due
- to differences in corrupted stream recorvery logic between the two APIs.

-------------

-Remarks
--------
-Close the decoder with `drflac_close()`.

-
-This function will automatically detect whether or not you are attempting to open a native or Ogg encapsulated FLAC, both of which should work seamlessly
-without any manual intervention. Ogg encapsulation also works with multiplexed streams which basically means it can play FLAC encoded audio tracks in videos.
-
-This is the lowest level function for opening a FLAC stream. You can also use `drflac_open_file()` and `drflac_open_memory()` to open the stream from a file or
-from a block of memory respectively.
-
-The STREAMINFO block must be present for this to succeed. Use `drflac_open_relaxed()` to open a FLAC stream where the header may not be present.
-
-Use `drflac_open_with_metadata()` if you need access to metadata.

-Close the decoder with `drflac_close()`.

-
-This is slower than `drflac_open()`, so avoid this one if you don't need metadata. Internally, this will allocate and free memory on the heap for every
-metadata block except for STREAMINFO and PADDING blocks.
-
-The caller is notified of the metadata via the `onMeta` callback. All metadata blocks will be handled before the function returns. This callback takes a
-pointer to a `drflac_metadata` object which is a union containing the data of all relevant metadata blocks. Use the `type` member to discriminate against
-the different metadata types.
-
-The STREAMINFO block must be present for this to succeed. Use `drflac_open_with_metadata_relaxed()` to open a FLAC stream where the header may not be present.
-
-Note that this will behave inconsistently with `drflac_open()` if the stream is an Ogg encapsulated stream and a metadata block is corrupted. This is due to
-the way the Ogg stream recovers from corrupted pages. When `drflac_open_with_metadata()` is being used, the open routine will try to read the contents of the
-metadata block, whereas `drflac_open()` will simply seek past it (for the sake of efficiency). This inconsistency can result in different samples being
-returned depending on whether or not the stream is being opened with metadata.

- It's critical for competitive decoding performance that this function be highly optimal. With MSVC we can use the __lzcnt64() and __lzcnt() intrinsics
- to achieve good performance, however on GCC and Clang it's a little bit more annoying. The __builtin_clzl() and __builtin_clzll() intrinsics leave
- it undefined as to the return value when `x` is 0. We need this to be well defined as returning 32 or 64, depending on whether or not it's a 32- or
- 64-bit build. To work around this we would need to add a conditional to check for the x = 0 case, but this creates unnecessary inefficiency. To work
- around this problem I have written some inline assembly to emit the LZCNT (x86) or CLZ (ARM) instruction directly which removes the need to include
- the conditional. This has worked well in the past, but for some reason Clang's MSVC compatible driver, clang-cl, does not seem to be handling this
- in the same way as the normal Clang driver. It seems that `clang-cl` is just outputting the wrong results sometimes, maybe due to some register
- getting clobbered?
-
- I'm not sure if this is a bug with dr_flac's inlined assembly (most likely), a bug in `clang-cl` or just a misunderstanding on my part with inline
- assembly rules for `clang-cl`. If somebody can identify an error in dr_flac's inlined assembly I'm happy to get that fixed.
-
- Fortunately there is an easy workaround for this. Clang implements MSVC-specific intrinsics for compatibility. It also defines _MSC_VER for extra
- compatibility. We can therefore just check for _MSC_VER and use the MSVC intrinsic which, fortunately for us, Clang supports. It would still be nice
- to know how to fix the inlined assembly for correctness sake, however.

- There are two ways to find the sample and seek past irrelevant frames:

-
- Both of these options have their own pros and cons. Using the native FLAC decoder is slower because it needs to
- do a full decode of the frame. Using Ogg's framing system is faster, but more complicated and involves some code
- duplication for the decoding of frame headers.
-
- Another thing to consider is that using the Ogg framing system will perform direct seeking of the physical Ogg
- bitstream. This is important to consider because it means we cannot read data from the drflac_bs object using the
- standard drflac__*() APIs because that will read in extra data for its own internal caching which in turn breaks
- the positioning of the read pointer of the physical Ogg bitstream. Therefore, anything that would normally be read
- using the native FLAC decoding APIs, such as drflac__read_next_flac_frame_header(), need to be re-implemented so as to
- avoid the use of the drflac_bs object.
-
- Considering these issues, I have decided to use the slower native FLAC decoding method for the following reasons:
- 1) Seeking is already partially accelerated using Ogg's paging system in the code block above.
- 2) Seeking in an Ogg encapsulated FLAC stream is probably quite uncommon.
- 3) Simplicity.

-
-v0.12.0 - 2019-09-23
- - API CHANGE: Add support for user defined memory allocation routines. This system allows the program to specify their own memory allocation
- routines with a user data pointer for client-specific contextual data. This adds an extra parameter to the end of the following APIs:
- - drflac_open()
- - drflac_open_relaxed()
- - drflac_open_with_metadata()
- - drflac_open_with_metadata_relaxed()
- - drflac_open_file()
- - drflac_open_file_with_metadata()
- - drflac_open_memory()
- - drflac_open_memory_with_metadata()
- - drflac_open_and_read_pcm_frames_s32()
- - drflac_open_and_read_pcm_frames_s16()
- - drflac_open_and_read_pcm_frames_f32()
- - drflac_open_file_and_read_pcm_frames_s32()
- - drflac_open_file_and_read_pcm_frames_s16()
- - drflac_open_file_and_read_pcm_frames_f32()
- - drflac_open_memory_and_read_pcm_frames_s32()
- - drflac_open_memory_and_read_pcm_frames_s16()
- - drflac_open_memory_and_read_pcm_frames_f32()
- Set this extra parameter to NULL to use defaults which is the same as the previous behaviour. Setting this NULL will use
- DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE.
- - Remove deprecated APIs:
- - drflac_read_s32()
- - drflac_read_s16()
- - drflac_read_f32()
- - drflac_seek_to_sample()
- - drflac_open_and_decode_s32()
- - drflac_open_and_decode_s16()
- - drflac_open_and_decode_f32()
- - drflac_open_and_decode_file_s32()
- - drflac_open_and_decode_file_s16()
- - drflac_open_and_decode_file_f32()
- - drflac_open_and_decode_memory_s32()
- - drflac_open_and_decode_memory_s16()
- - drflac_open_and_decode_memory_f32()
- - Remove drflac.totalSampleCount which is now replaced with drflac.totalPCMFrameCount. You can emulate drflac.totalSampleCount
- by doing pFlac->totalPCMFrameCount*pFlac->channels.
- - Rename drflac.currentFrame to drflac.currentFLACFrame to remove ambiguity with PCM frames.
- - Fix errors when seeking to the end of a stream.
- - Optimizations to seeking.
- - SSE improvements and optimizations.
- - ARM NEON optimizations.
- - Optimizations to drflac_read_pcm_frames_s16().
- - Optimizations to drflac_read_pcm_frames_s32().
-
-v0.11.10 - 2019-06-26
- - Fix a compiler error.
-
-v0.11.9 - 2019-06-16
- - Silence some ThreadSanitizer warnings.
-
-v0.11.8 - 2019-05-21

-v0.11.0 - 2018-12-16
- - API CHANGE: Deprecated drflac_read_s32(), drflac_read_s16() and drflac_read_f32() and replaced them with
- drflac_read_pcm_frames_s32(), drflac_read_pcm_frames_s16() and drflac_read_pcm_frames_f32(). The new APIs take
- and return PCM frame counts instead of sample counts. To upgrade you will need to change the input count by
- dividing it by the channel count, and then do the same with the return value.

-
-v0.6 - 2017-07-22

- never existed. Frames are checked against their sync code, the CRC-8 of the frame header and the CRC-16 of the whole frame.
-
-v0.5 - 2017-07-16
- - Fix typos.
- - Change drflac_bool* types to unsigned.
- - Add CRC checking. This makes dr_flac slower, but can be disabled with #define DR_FLAC_NO_CRC.

-*/
-
-/*
-RELEASE NOTES - VERSION 0.6
-===========================
-Version 0.6 includes breaking changes with the configuration of decoders. The ability to customize the number of output channels and the sample rate has been
-removed. You must now use the channel count and sample rate reported by the MP3 stream itself, and all channel and sample rate conversion must be done
-yourself.
-
-
-Changes to Initialization
--------------------------
-Previously, `drmp3_init()`, etc. took a pointer to a `drmp3_config` object that allowed you to customize the output channels and sample rate. This has been
-removed. If you need the old behaviour you will need to convert the data yourself or just not upgrade. The following APIs have changed.
-
- `drmp3_init()`
- `drmp3_init_memory()`
- `drmp3_init_file()`
-
-
-Miscellaneous Changes
----------------------
-Support for loading a file from a `wchar_t` string has been added via the `drmp3_init_file_w()` API.
-*/
-
-/*
-Introducation
-=============
-dr_mp3 is a single file library. To use it, do something like the following in one .c file.
-
- ```c
- #define DR_MP3_IMPLEMENTATION
- #include "dr_mp3.h"
- ```
-
-You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following:
-
- ```c
- drmp3 mp3;
- if (!drmp3_init_file(&mp3, "MySong.mp3", NULL)) {
- // Failed to open file
- }
-
- ...
-
- drmp3_uint64 framesRead = drmp3_read_pcm_frames_f32(pMP3, framesToRead, pFrames);
- ```
-
-The drmp3 object is transparent so you can get access to the channel count and sample rate like so:
-
- ```
- drmp3_uint32 channels = mp3.channels;
- drmp3_uint32 sampleRate = mp3.sampleRate;
- ```
-
-The example above initializes a decoder from a file, but you can also initialize it from a block of memory and read and seek callbacks with
-`drmp3_init_memory()` and `drmp3_init()` respectively.
-
-You do not need to do any annoying memory management when reading PCM frames - this is all managed internally. You can request any number of PCM frames in each
-call to `drmp3_read_pcm_frames_f32()` and it will return as many PCM frames as it can, up to the requested amount.
-
-You can also decode an entire file in one go with `drmp3_open_and_read_pcm_frames_f32()`, `drmp3_open_memory_and_read_pcm_frames_f32()` and
-`drmp3_open_file_and_read_pcm_frames_f32()`.
-
-
-Build Options
-=============
-#define these options before including this file.
-
-#define DR_MP3_NO_STDIO
- Disable drmp3_init_file(), etc.
-
-#define DR_MP3_NO_SIMD
- Disable SIMD optimizations.

-DIFFERENCES BETWEEN minimp3 AND dr_mp3
-======================================
-- First, keep in mind that minimp3 (https://github.com/lieff/minimp3) is where all the real work was done. All of the
- code relating to the actual decoding remains mostly unmodified, apart from some namespacing changes.
-- dr_mp3 adds a pulling style API which allows you to deliver raw data via callbacks. So, rather than pushing data
- to the decoder, the decoder _pulls_ data from your callbacks.
-- In addition to callbacks, a decoder can be initialized from a block of memory and a file.
-- The dr_mp3 pull API reads PCM frames rather than whole MP3 frames.
-- dr_mp3 adds convenience APIs for opening and decoding entire files in one go.
-- dr_mp3 is fully namespaced, including the implementation section, which is more suitable when compiling projects
- as a single translation unit (aka unity builds). At the time of writing this, a unity build is not possible when
- using minimp3 in conjunction with stb_vorbis. dr_mp3 addresses this.
-*/
-
-/*
-RELEASE NOTES - v0.5.0
-=======================
-Version 0.5.0 has breaking API changes.
-
-Improved Client-Defined Memory Allocation
------------------------------------------
-The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
-existing system of DRMP3_MALLOC, DRMP3_REALLOC and DRMP3_FREE are still in place and will be used by default when no custom
-allocation callbacks are specified.
-
-To use the new system, you pass in a pointer to a drmp3_allocation_callbacks object to drmp3_init() and family, like this:
-
- void* my_malloc(size_t sz, void* pUserData)
- {
- return malloc(sz);
- }
- void* my_realloc(void* p, size_t sz, void* pUserData)
- {
- return realloc(p, sz);
- }
- void my_free(void* p, void* pUserData)
- {
- free(p);
- }
-
- ...
-
- drmp3_allocation_callbacks allocationCallbacks;
- allocationCallbacks.pUserData = &myData;
- allocationCallbacks.onMalloc = my_malloc;
- allocationCallbacks.onRealloc = my_realloc;
- allocationCallbacks.onFree = my_free;
- drmp3_init_file(&mp3, "my_file.mp3", NULL, &allocationCallbacks);
-
-The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
-
-Passing in null for the allocation callbacks object will cause dr_mp3 to use defaults which is the same as DRMP3_MALLOC,
-DRMP3_REALLOC and DRMP3_FREE and the equivalent of how it worked in previous versions.
-
-Every API that opens a drmp3 object now takes this extra parameter. These include the following:
-
- drmp3_init()
- drmp3_init_file()
- drmp3_init_memory()
- drmp3_open_and_read_pcm_frames_f32()
- drmp3_open_and_read_pcm_frames_s16()
- drmp3_open_memory_and_read_pcm_frames_f32()
- drmp3_open_memory_and_read_pcm_frames_s16()
- drmp3_open_file_and_read_pcm_frames_f32()
- drmp3_open_file_and_read_pcm_frames_s16()
-
-Renamed APIs
-------------
-The following APIs have been renamed for consistency with other dr_* libraries and to make it clear that they return PCM frame
-counts rather than sample counts.
-
- drmp3_open_and_read_f32() -> drmp3_open_and_read_pcm_frames_f32()
- drmp3_open_and_read_s16() -> drmp3_open_and_read_pcm_frames_s16()
- drmp3_open_memory_and_read_f32() -> drmp3_open_memory_and_read_pcm_frames_f32()
- drmp3_open_memory_and_read_s16() -> drmp3_open_memory_and_read_pcm_frames_s16()
- drmp3_open_file_and_read_f32() -> drmp3_open_file_and_read_pcm_frames_f32()
- drmp3_open_file_and_read_s16() -> drmp3_open_file_and_read_pcm_frames_s16()

-RELEASE NOTES - VERSION 0.12
-============================
-Version 0.12 includes breaking changes to custom chunk handling.
-
-
-Changes to Chunk Callback
--------------------------
-dr_wav supports the ability to fire a callback when a chunk is encounted (except for WAVE and FMT chunks). The callback has been updated to include both the
-container (RIFF or Wave64) and the FMT chunk which contains information about the format of the data in the wave file.
-
-Previously, there was no direct way to determine the container, and therefore no way to discriminate against the different IDs in the chunk header (RIFF and
-Wave64 containers encode chunk ID's differently). The `container` parameter can be used to know which ID to use.
-
-Sometimes it can be useful to know the data format at the time the chunk callback is fired. A pointer to a `drwav_fmt` object is now passed into the chunk
-callback which will give you information about the data format. To determine the sample format, use `drwav_fmt_get_format()`. This will return one of the
-`DR_WAVE_FORMAT_*` tokens.
-*/
-
-/*
-Introduction
-============
-This is a single file library. To use it, do something like the following in one .c file.
-
- ```c
- #define DR_WAV_IMPLEMENTATION
- #include "dr_wav.h"
- ```
-
-You can then #include this file in other parts of the program as you would with any other header file. Do something like the following to read audio data:
-
- ```c
- drwav wav;
- if (!drwav_init_file(&wav, "my_song.wav", NULL)) {
- // Error opening WAV file.
- }
-
- drwav_int32* pDecodedInterleavedPCMFrames = malloc(wav.totalPCMFrameCount * wav.channels * sizeof(drwav_int32));
- size_t numberOfSamplesActuallyDecoded = drwav_read_pcm_frames_s32(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames);
-
- ...
-
- drwav_uninit(&wav);
- ```
-
-If you just want to quickly open and read the audio data in a single operation you can do something like this:
-
- ```c
- unsigned int channels;
- unsigned int sampleRate;
- drwav_uint64 totalPCMFrameCount;
- float* pSampleData = drwav_open_file_and_read_pcm_frames_f32("my_song.wav", &channels, &sampleRate, &totalPCMFrameCount, NULL);
- if (pSampleData == NULL) {
- // Error opening and reading WAV file.
- }
-
- ...
-
- drwav_free(pSampleData, NULL);
- ```
-
-The examples above use versions of the API that convert the audio data to a consistent format (32-bit signed PCM, in this case), but you can still output the
-audio data in its internal format (see notes below for supported formats):
-
- ```c
- size_t framesRead = drwav_read_pcm_frames(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames);
- ```
-
-You can also read the raw bytes of audio data, which could be useful if dr_wav does not have native support for a particular data format:
-
- ```c
- size_t bytesRead = drwav_read_raw(&wav, bytesToRead, pRawDataBuffer);
- ```
-
-dr_wav can also be used to output WAV files. This does not currently support compressed formats. To use this, look at `drwav_init_write()`,
-`drwav_init_file_write()`, etc. Use `drwav_write_pcm_frames()` to write samples, or `drwav_write_raw()` to write raw data in the "data" chunk.
-
- ```c
- drwav_data_format format;
- format.container = drwav_container_riff; // <-- drwav_container_riff = normal WAV files, drwav_container_w64 = Sony Wave64.
- format.format = DR_WAVE_FORMAT_PCM; // <-- Any of the DR_WAVE_FORMAT_* codes.
- format.channels = 2;
- format.sampleRate = 44100;
- format.bitsPerSample = 16;
- drwav_init_file_write(&wav, "data/recording.wav", &format, NULL);
-
- ...
-
- drwav_uint64 framesWritten = drwav_write_pcm_frames(pWav, frameCount, pSamples);
- ```
-
-dr_wav has seamless support the Sony Wave64 format. The decoder will automatically detect it and it should Just Work without any manual intervention.
-
-
-Build Options
-=============
-#define these options before including this file.
-
-#define DR_WAV_NO_CONVERSION_API
- Disables conversion APIs such as `drwav_read_pcm_frames_f32()` and `drwav_s16_to_f32()`.
-
-#define DR_WAV_NO_STDIO
- Disables APIs that initialize a decoder from a file such as `drwav_init_file()`, `drwav_init_file_write()`, etc.
-
-
-
-Notes
-=====
-- Samples are always interleaved.
-- The default read function does not do any data conversion. Use `drwav_read_pcm_frames_f32()`, `drwav_read_pcm_frames_s32()` and `drwav_read_pcm_frames_s16()`
- to read and convert audio data to 32-bit floating point, signed 32-bit integer and signed 16-bit integer samples respectively. Tested and supported internal
- formats include the following:
- - Unsigned 8-bit PCM
- - Signed 12-bit PCM
- - Signed 16-bit PCM
- - Signed 24-bit PCM
- - Signed 32-bit PCM
- - IEEE 32-bit floating point
- - IEEE 64-bit floating point
- - A-law and u-law
- - Microsoft ADPCM
- - IMA ADPCM (DVI, format code 0x11)
-- dr_wav will try to read the WAV file as best it can, even if it's not strictly conformant to the WAV format.

-RELEASE NOTES - v0.11.0
-=======================
-Version 0.11.0 has breaking API changes.
-
-Improved Client-Defined Memory Allocation
------------------------------------------
-The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
-existing system of DRWAV_MALLOC, DRWAV_REALLOC and DRWAV_FREE are still in place and will be used by default when no custom
-allocation callbacks are specified.
-
-To use the new system, you pass in a pointer to a drwav_allocation_callbacks object to drwav_init() and family, like this:
-
- void* my_malloc(size_t sz, void* pUserData)
- {
- return malloc(sz);
- }
- void* my_realloc(void* p, size_t sz, void* pUserData)
- {
- return realloc(p, sz);
- }
- void my_free(void* p, void* pUserData)
- {
- free(p);
- }
-
- ...
-
- drwav_allocation_callbacks allocationCallbacks;
- allocationCallbacks.pUserData = &myData;
- allocationCallbacks.onMalloc = my_malloc;
- allocationCallbacks.onRealloc = my_realloc;
- allocationCallbacks.onFree = my_free;
- drwav_init_file(&wav, "my_file.wav", &allocationCallbacks);
-
-The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
-
-Passing in null for the allocation callbacks object will cause dr_wav to use defaults which is the same as DRWAV_MALLOC,
-DRWAV_REALLOC and DRWAV_FREE and the equivalent of how it worked in previous versions.
-
-Every API that opens a drwav object now takes this extra parameter. These include the following:
-
- drwav_init()
- drwav_init_ex()
- drwav_init_file()
- drwav_init_file_ex()
- drwav_init_file_w()
- drwav_init_file_w_ex()
- drwav_init_memory()
- drwav_init_memory_ex()
- drwav_init_write()
- drwav_init_write_sequential()
- drwav_init_write_sequential_pcm_frames()
- drwav_init_file_write()
- drwav_init_file_write_sequential()
- drwav_init_file_write_sequential_pcm_frames()
- drwav_init_file_write_w()
- drwav_init_file_write_sequential_w()
- drwav_init_file_write_sequential_pcm_frames_w()
- drwav_init_memory_write()
- drwav_init_memory_write_sequential()
- drwav_init_memory_write_sequential_pcm_frames()
- drwav_open_and_read_pcm_frames_s16()
- drwav_open_and_read_pcm_frames_f32()
- drwav_open_and_read_pcm_frames_s32()
- drwav_open_file_and_read_pcm_frames_s16()
- drwav_open_file_and_read_pcm_frames_f32()
- drwav_open_file_and_read_pcm_frames_s32()
- drwav_open_file_and_read_pcm_frames_s16_w()
- drwav_open_file_and_read_pcm_frames_f32_w()
- drwav_open_file_and_read_pcm_frames_s32_w()
- drwav_open_memory_and_read_pcm_frames_s16()
- drwav_open_memory_and_read_pcm_frames_f32()
- drwav_open_memory_and_read_pcm_frames_s32()
-
-Endian Improvements
--------------------
-Previously, the following APIs returned little-endian audio data. These now return native-endian data. This improves compatibility
-on big-endian architectures.
-
- drwav_read_pcm_frames()
- drwav_read_pcm_frames_s16()
- drwav_read_pcm_frames_s32()
- drwav_read_pcm_frames_f32()
- drwav_open_and_read_pcm_frames_s16()
- drwav_open_and_read_pcm_frames_s32()
- drwav_open_and_read_pcm_frames_f32()
- drwav_open_file_and_read_pcm_frames_s16()
- drwav_open_file_and_read_pcm_frames_s32()
- drwav_open_file_and_read_pcm_frames_f32()
- drwav_open_file_and_read_pcm_frames_s16_w()
- drwav_open_file_and_read_pcm_frames_s32_w()
- drwav_open_file_and_read_pcm_frames_f32_w()
- drwav_open_memory_and_read_pcm_frames_s16()
- drwav_open_memory_and_read_pcm_frames_s32()
- drwav_open_memory_and_read_pcm_frames_f32()
-
-APIs have been added to give you explicit control over whether or not audio data is read or written in big- or little-endian byte
-order:
-
- drwav_read_pcm_frames_le()
- drwav_read_pcm_frames_be()
- drwav_read_pcm_frames_s16le()
- drwav_read_pcm_frames_s16be()
- drwav_read_pcm_frames_f32le()
- drwav_read_pcm_frames_f32be()
- drwav_read_pcm_frames_s32le()
- drwav_read_pcm_frames_s32be()
- drwav_write_pcm_frames_le()
- drwav_write_pcm_frames_be()
-
-Removed APIs
-------------
-The following APIs were deprecated in version 0.10.0 and have now been removed:
-
- drwav_open()
- drwav_open_ex()
- drwav_open_write()
- drwav_open_write_sequential()
- drwav_open_file()
- drwav_open_file_ex()
- drwav_open_file_write()
- drwav_open_file_write_sequential()
- drwav_open_memory()
- drwav_open_memory_ex()
- drwav_open_memory_write()
- drwav_open_memory_write_sequential()
- drwav_close()
-
-
-
-RELEASE NOTES - v0.10.0
-=======================
-Version 0.10.0 has breaking API changes. There are no significant bug fixes in this release, so if you are affected you do
-not need to upgrade.
-
-Removed APIs
-------------
-The following APIs were deprecated in version 0.9.0 and have been completely removed in version 0.10.0:
-
- drwav_read()
- drwav_read_s16()
- drwav_read_f32()
- drwav_read_s32()
- drwav_seek_to_sample()
- drwav_write()
- drwav_open_and_read_s16()
- drwav_open_and_read_f32()
- drwav_open_and_read_s32()
- drwav_open_file_and_read_s16()
- drwav_open_file_and_read_f32()
- drwav_open_file_and_read_s32()
- drwav_open_memory_and_read_s16()
- drwav_open_memory_and_read_f32()
- drwav_open_memory_and_read_s32()
- drwav::totalSampleCount
-
-See release notes for version 0.9.0 at the bottom of this file for replacement APIs.
-
-Deprecated APIs
----------------
-The following APIs have been deprecated. There is a confusing and completely arbitrary difference between drwav_init*() and
-drwav_open*(), where drwav_init*() initializes a pre-allocated drwav object, whereas drwav_open*() will first allocated a
-drwav object on the heap and then initialize it. drwav_open*() has been deprecated which means you must now use a pre-
-allocated drwav object with drwav_init*(). If you need the previous functionality, you can just do a malloc() followed by
-a called to one of the drwav_init*() APIs.
-
- drwav_open()
- drwav_open_ex()
- drwav_open_write()
- drwav_open_write_sequential()
- drwav_open_file()
- drwav_open_file_ex()
- drwav_open_file_write()
- drwav_open_file_write_sequential()
- drwav_open_memory()
- drwav_open_memory_ex()
- drwav_open_memory_write()
- drwav_open_memory_write_sequential()
- drwav_close()
-
-These APIs will be removed completely in a future version. The rationale for this change is to remove confusion between the
-two different ways to initialize a drwav object.

-## Introduction
-
-GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan
-application development. It provides a simple, platform-independent API for
-creating windows, contexts and surfaces, reading input, handling events, etc.
-
-GLFW natively supports Windows, macOS and Linux and other Unix-like systems. On
-Linux both X11 and Wayland are supported.
-
-GLFW is licensed under the [zlib/libpng
-license](http://www.glfw.org/license.html).
-
-You can [download](http://www.glfw.org/download.html) the latest stable release
-as source or Windows binaries, or fetch the `latest` branch from GitHub. Each
-release starting with 3.0 also has a corresponding [annotated
-tag](https://github.com/glfw/glfw/releases) with source and binary archives.
-
-The [documentation](http://www.glfw.org/docs/latest/) is available online and is
-included in all source and binary archives. See the [release
-notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and
-deprecations in the latest release. For more details see the [version
-history](http://www.glfw.org/changelog.html).
-
-The `master` branch is the stable integration branch and _should_ always compile
-and run on all supported platforms, although details of newly added features may
-change until they have been included in a release. New features and many bug
-fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until
-they are stable enough to merge.
-
-If you are new to GLFW, you may find the
-[tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful. If
-you have used GLFW 2 in the past, there is a [transition
-guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW
-3 API.
-
-
-## Compiling GLFW
-
-GLFW itself requires only the headers and libraries for your OS and window
-system. It does not need the headers for any context creation API (WGL, GLX,
-EGL, NSGL, OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable
-support for them.
-
-GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and
-MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
-and Clang. It will likely compile in other environments as well, but this is
-not regularly tested.
-
-There are [pre-compiled Windows binaries](http://www.glfw.org/download.html)
-available for all supported compilers.
-
-See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for
-more information about how to compile GLFW yourself.
-
-
-## Using GLFW
-
-See the [documentation](http://www.glfw.org/docs/latest/) for tutorials, guides
-and the API reference.
-
-
-## Contributing to GLFW
-
-See the [contribution
-guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
-more information.
-
-
-## System requirements
-
-GLFW supports Windows XP and later and macOS 10.8 and later. Linux and other
-Unix-like systems running the X Window System are supported even without
-a desktop environment or modern extensions, although some features require
-a running window or clipboard manager. The OSMesa backend requires Mesa 6.3.
-
-See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html)
-in the documentation for more information.
-
-
-## Dependencies
-
-GLFW itself needs only CMake 3.1 or later and the headers and libraries for your
-OS and window system.
-
-The examples and test programs depend on a number of tiny libraries. These are
-located in the `deps/` directory.
-
- - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
- with command-line options
- - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
- examples
- - [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan
- functions
- - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
- examples
- - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI
- - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk
-
-The documentation is generated with [Doxygen](http://doxygen.org/) if CMake can
-find that tool.
-
-
-## Reporting bugs
-
-Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).
-Please check the [contribution
-guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
-information on what to include when reporting a bug.

- *
- * The master copy of khrplatform.h is maintained in the Khronos EGL
- * Registry repository at https://github.com/KhronosGroup/EGL-Registry
- * The last semantic modification to khrplatform.h was at commit ID:
- * 67a3e0864c2d75ea5287b9f3d2eb74a745936692
- *
- * Adopters may modify this file to suit their platform. Adopters are
- * encouraged to submit platform specific modifications to the Khronos
- * group so that they can be included in future versions of this file.
- * Please submit changes by filing pull requests or issues on
- * the EGL Registry repository linked above.
- *
- *
- * See the Implementer's Guidelines for information about where this file
- * should be located on your system and for more details of its use:
- * http://www.khronos.org/registry/implementers_guide.pdf
- *
- * This file should be included as
- * #include <KHR/khrplatform.h>
- * by Khronos client API header files that use its types and defines.
- *
- * The types in khrplatform.h should only be used to define API-specific types.
- *
- * Types defined in khrplatform.h:
- * khronos_int8_t signed 8 bit
- * khronos_uint8_t unsigned 8 bit
- * khronos_int16_t signed 16 bit
- * khronos_uint16_t unsigned 16 bit
- * khronos_int32_t signed 32 bit
- * khronos_uint32_t unsigned 32 bit
- * khronos_int64_t signed 64 bit
- * khronos_uint64_t unsigned 64 bit
- * khronos_intptr_t signed same number of bits as a pointer
- * khronos_uintptr_t unsigned same number of bits as a pointer
- * khronos_ssize_t signed size
- * khronos_usize_t unsigned size
- * khronos_float_t signed 32 bit floating point
- * khronos_time_ns_t unsigned 64 bit time in nanoseconds
- * khronos_utime_nanoseconds_t unsigned time interval or absolute time in
- * nanoseconds
- * khronos_stime_nanoseconds_t signed time interval in nanoseconds
- * khronos_boolean_enum_t enumerated boolean type. This should
- * only be used as a base type when a client API's boolean type is
- * an enum. Client APIs which use an integer or other type for
- * booleans cannot use this as the base type for their boolean.
- *
- * Tokens defined in khrplatform.h:
- *
- * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
- *
- * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
- * KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
- *
- * Calling convention macros defined in this file:
- * KHRONOS_APICALL
- * KHRONOS_APIENTRY
- * KHRONOS_APIATTRIBUTES
- *
- * These may be used in function prototypes as:

- *
- * This function creates a window and its associated OpenGL or OpenGL ES
- * context. Most of the options controlling how the window and its context
- * should be created are specified with [window hints](@ref window_hints).
- *
- * Successful creation does not change which context is current. Before you
- * can use the newly created context, you need to
- * [make it current](@ref context_current). For information about the `share`
- * parameter, see @ref context_sharing.
- *
- * The created window, framebuffer and context may differ from what you
- * requested, as not all parameters and hints are
- * [hard constraints](@ref window_hints_hard). This includes the size of the
- * window, especially for full screen windows. To query the actual attributes
- * of the created window, framebuffer and context, see @ref
- * glfwGetWindowAttrib, @ref glfwGetWindowSize and @ref glfwGetFramebufferSize.
- *
- * To create a full screen window, you need to specify the monitor the window
- * will cover. If no monitor is specified, the window will be windowed mode.
- * Unless you have a way for the user to choose a specific monitor, it is
- * recommended that you pick the primary monitor. For more information on how
- * to query connected monitors, see @ref monitor_monitors.
- *
- * For full screen windows, the specified size becomes the resolution of the
- * window's _desired video mode_. As long as a full screen window is not
- * iconified, the supported video mode most closely matching the desired video
- * mode is set for the specified monitor. For more information about full
- * screen windows, including the creation of so called _windowed full screen_
- * or _borderless full screen_ windows, see @ref window_windowed_full_screen.
- *
- * Once you have created the window, you can switch it between windowed and
- * full screen mode with @ref glfwSetWindowMonitor. This will not affect its
- * OpenGL or OpenGL ES context.
- *
- * By default, newly created windows use the placement recommended by the
- * window system. To create the window at a specific position, make it
- * initially invisible using the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window
- * hint, set its [position](@ref window_pos) and then [show](@ref window_hide)
- * it.
- *
- * As long as at least one full screen window is not iconified, the screensaver
- * is prohibited from starting.
- *
- * Window systems put limits on window sizes. Very large or very small window
- * dimensions may be overridden by the window system on creation. Check the
- * actual [size](@ref window_size) after creation.
- *
- * The [swap interval](@ref buffer_swap) is not set during window creation and
- * the initial value may vary depending on driver settings and defaults.
- *
- * @param[in] width The desired width, in screen coordinates, of the window.
- * This must be greater than zero.
- * @param[in] height The desired height, in screen coordinates, of the window.
- * This must be greater than zero.
- * @param[in] title The initial, UTF-8 encoded window title.
- * @param[in] monitor The monitor to use for full screen mode, or `NULL` for
- * windowed mode.
- * @param[in] share The window whose context to share resources with, or `NULL`
- * to not share resources.
- * @return The handle of the created window, or `NULL` if an

- *
- * @remark @win32 Window creation will fail if the Microsoft GDI software
- * OpenGL implementation is the only one available.
- *
- * @remark @win32 If the executable has an icon resource named `GLFW_ICON,` it
- * will be set as the initial icon for the window. If no such icon is present,
- * the `IDI_APPLICATION` icon will be used instead. To set a different icon,
- * see @ref glfwSetWindowIcon.
- *
- * @remark @win32 The context to share resources with must not be current on
- * any other thread.
- *
- * @remark @macos The OS only supports core profile contexts for OpenGL
- * versions 3.2 and later. Before creating an OpenGL context of version 3.2 or
- * later you must set the [GLFW_OPENGL_PROFILE](@ref GLFW_OPENGL_PROFILE_hint)
- * hint accordingly. OpenGL 3.0 and 3.1 contexts are not supported at all
- * on macOS.
- *
- * @remark @macos The GLFW window has no icon, as it is not a document
- * window, but the dock icon will be the same as the application bundle's icon.
- * For more information on bundles, see the
- * [Bundle Programming Guide](https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/)
- * in the Mac Developer Library.
- *
- * @remark @macos On OS X 10.10 and later the window frame will not be rendered
- * at full resolution on Retina displays unless the

- * in the Mac Developer Library. The GLFW test and example programs use
- * a custom `Info.plist` template for this, which can be found as
- * `CMake/Info.plist.in` in the source tree.
- *
- * @remark @macos When activating frame autosaving with
- * [GLFW_COCOA_FRAME_NAME](@ref GLFW_COCOA_FRAME_NAME_hint), the specified
- * window size and position may be overridden by previously saved values.
- *
- * @remark @x11 Some window managers will not respect the placement of
- * initially hidden windows.
- *
- * @remark @x11 Due to the asynchronous nature of X11, it may take a moment for
- * a window to reach its requested state. This means you may not be able to
- * query the final size, position or other attributes directly after window
- * creation.
- *
- * @remark @x11 The class part of the `WM_CLASS` window property will by
- * default be set to the window title passed to this function. The instance
- * part will use the contents of the `RESOURCE_NAME` environment variable, if
- * present and not empty, or fall back to the window title. Set the
- * [GLFW_X11_CLASS_NAME](@ref GLFW_X11_CLASS_NAME_hint) and
- * [GLFW_X11_INSTANCE_NAME](@ref GLFW_X11_INSTANCE_NAME_hint) window hints to
- * override this.
- *
- * @remark @wayland Compositors should implement the xdg-decoration protocol
- * for GLFW to decorate the window properly. If this protocol isn't
- * supported, or if the compositor prefers client-side decorations, a very
- * simple fallback frame will be drawn using the wp_viewporter protocol. A
- * compositor can still emit close, maximize or fullscreen events, using for
- * instance a keybind mechanism. If neither of these protocols is supported,
- * the window won't be decorated.
- *
- * @remark @wayland A full screen window will not attempt to change the mode,

- * Marcus: This code was originally written by Markus G. Kuhn.
- * I have made some slight changes (trimmed it down a bit from >60 KB to
- * 20 KB), but the functionality is the same.
- */
-
-/*
- * This module converts keysym values into the corresponding ISO 10646
- * (UCS, Unicode) values.
- *
- * The array keysymtab[] contains pairs of X11 keysym values for graphical
- * characters and the corresponding Unicode value. The function
- * _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
- * search, therefore keysymtab[] must remain SORTED by keysym value.
- *
- * We allow to represent any UCS character in the range U-00000000 to
- * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
- * This admittedly does not cover the entire 31-bit space of UCS, but
- * it does cover all of the characters up to U-10FFFF, which can be
- * represented by UTF-16, and more, and it is very unlikely that higher
- * UCS codes will ever be assigned by ISO. So to get Unicode character
- * U+ABCD you can directly use keysym 0x0100abcd.
- *
- * Original author: Markus G. Kuhn <mkuhn@acm.org>, University of
- * Cambridge, April 2001
- *
- * Special thanks to Richard Verhoeven <river@win.tue.nl> for preparing
- * an initial draft of the mapping table.

-1. Introduction
-===============
-miniaudio is a single file library for audio playback and capture. To use it, do the following in one .c file:
-
- ```c
- #define MINIAUDIO_IMPLEMENTATION
- #include "miniaudio.h"
- ```
-
-You can do `#include "miniaudio.h"` in other parts of the program just like any other header.
-
-miniaudio uses the concept of a "device" as the abstraction for physical devices. The idea is that you choose a physical device to emit or capture audio from,
-and then move data to/from the device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a callback which you specify when
-initializing the device.
-
-When initializing the device you first need to configure it. The device configuration allows you to specify things like the format of the data delivered via
-the callback, the size of the internal buffer and the ID of the device you want to emit or capture audio from.
-
-Once you have the device configuration set up you can initialize the device. When initializing a device you need to allocate memory for the device object
-beforehand. This gives the application complete control over how the memory is allocated. In the example below we initialize a playback device on the stack,
-but you could allocate it on the heap if that suits your situation better.
-
- ```c
- void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount)
- {
- // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both
- // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than
- // frameCount frames.
- }
-
- int main()
- {
- ma_device_config config = ma_device_config_init(ma_device_type_playback);
- config.playback.format = ma_format_f32; // Set to ma_format_unknown to use the device's native format.
- config.playback.channels = 2; // Set to 0 to use the device's native channel count.
- config.sampleRate = 48000; // Set to 0 to use the device's native sample rate.
- config.dataCallback = data_callback; // This function will be called when miniaudio needs more data.
- config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData).
-
- ma_device device;
- if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) {
- return -1; // Failed to initialize the device.
- }
-
- ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually.
-
- // Do something here. Probably your program's main loop.
-
- ma_device_uninit(&device); // This will stop the device so no need to do that manually.
- return 0;
- }
- ```
-
-In the example above, `data_callback()` is where audio data is written and read from the device. The idea is in playback mode you cause sound to be emitted
-from the speakers by writing audio data to the output buffer (`pOutput` in the example). In capture mode you read data from the input buffer (`pInput`) to
-extract sound captured by the microphone. The `frameCount` parameter tells you how many frames can be written to the output buffer and read from the input
-buffer. A "frame" is one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 samples: one for the left, one for the right.
-The channel count is defined by the device config. The size in bytes of an individual sample is defined by the sample format which is also specified in the
-device config. Multi-channel audio data is always interleaved, which means the samples for each frame are stored next to each other in memory. For example, in
-a stereo stream the first pair of samples will be the left and right samples for the first frame, the second pair of samples will be the left and right samples
-for the second frame, etc.
-
-The configuration of the device is defined by the `ma_device_config` structure. The config object is always initialized with `ma_device_config_init()`. It's
-important to always initialize the config with this function as it initializes it with logical defaults and ensures your program doesn't break when new members
-are added to the `ma_device_config` structure. The example above uses a fairly simple and standard device configuration. The call to `ma_device_config_init()`
-takes a single parameter, which is whether or not the device is a playback, capture, duplex or loopback device (loopback devices are not supported on all
-backends). The `config.playback.format` member sets the sample format which can be one of the following (all formats are native-endian):
-
- +---------------+----------------------------------------+---------------------------+
- | Symbol | Description | Range |
- +---------------+----------------------------------------+---------------------------+
- | ma_format_f32 | 32-bit floating point | [-1, 1] |
- | ma_format_s16 | 16-bit signed integer | [-32768, 32767] |
- | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] |
- | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] |
- | ma_format_u8 | 8-bit unsigned integer | [0, 255] |
- +---------------+----------------------------------------+---------------------------+
-
-The `config.playback.channels` member sets the number of channels to use with the device. The channel count cannot exceed MA_MAX_CHANNELS. The
-`config.sampleRate` member sets the sample rate (which must be the same for both playback and capture in full-duplex configurations). This is usually set to
-44100 or 48000, but can be set to anything. It's recommended to keep this between 8000 and 384000, however.
-
-Note that leaving the format, channel count and/or sample rate at their default values will result in the internal device's native configuration being used
-which is useful if you want to avoid the overhead of miniaudio's automatic data conversion.
-
-In addition to the sample format, channel count and sample rate, the data callback and user data pointer are also set via the config. The user data pointer is
-not passed into the callback as a parameter, but is instead set to the `pUserData` member of `ma_device` which you can access directly since all miniaudio
-structures are transparent.
-
-Initializing the device is done with `ma_device_init()`. This will return a result code telling you what went wrong, if anything. On success it will return
-`MA_SUCCESS`. After initialization is complete the device will be in a stopped state. To start it, use `ma_device_start()`. Uninitializing the device will stop
-it, which is what the example above does, but you can also stop the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again.
-Note that it's important to never stop or start the device from inside the callback. This will result in a deadlock. Instead you set a variable or signal an
-event indicating that the device needs to stop and handle it in a different thread. The following APIs must never be called inside the callback:
-
- ```c
- ma_device_init()
- ma_device_init_ex()
- ma_device_uninit()
- ma_device_start()
- ma_device_stop()
- ```
-
-You must never try uninitializing and reinitializing a device inside the callback. You must also never try to stop and start it from inside the callback. There
-are a few other things you shouldn't do in the callback depending on your requirements, however this isn't so much a thread-safety thing, but rather a
-real-time processing thing which is beyond the scope of this introduction.
-
-The example above demonstrates the initialization of a playback device, but it works exactly the same for capture. All you need to do is change the device type
-from `ma_device_type_playback` to `ma_device_type_capture` when setting up the config, like so:
-
- ```c
- ma_device_config config = ma_device_config_init(ma_device_type_capture);
- config.capture.format = MY_FORMAT;
- config.capture.channels = MY_CHANNEL_COUNT;
- ```
-
-In the data callback you just read from the input buffer (`pInput` in the example above) and leave the output buffer alone (it will be set to NULL when the
-device type is set to `ma_device_type_capture`).
-
-These are the available device types and how you should handle the buffers in the callback:
-
- +-------------------------+--------------------------------------------------------+
- | Device Type | Callback Behavior |
- +-------------------------+--------------------------------------------------------+
- | ma_device_type_playback | Write to output buffer, leave input buffer untouched. |
- | ma_device_type_capture | Read from input buffer, leave output buffer untouched. |
- | ma_device_type_duplex | Read from input buffer, write to output buffer. |
- | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. |
- +-------------------------+--------------------------------------------------------+
-
-You will notice in the example above that the sample format and channel count is specified separately for playback and capture. This is to support different
-data formats between the playback and capture devices in a full-duplex system. An example may be that you want to capture audio data as a monaural stream (one
-channel), but output sound to a stereo speaker system. Note that if you use different formats between playback and capture in a full-duplex configuration you
-will need to convert the data yourself. There are functions available to help you do this which will be explained later.
-
-The example above did not specify a physical device to connect to which means it will use the operating system's default device. If you have multiple physical
-devices connected and you want to use a specific one you will need to specify the device ID in the configuration, like so:
-
- ```c
- config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device.
- config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device.
- ```
-
-To retrieve the device ID you will need to perform device enumeration, however this requires the use of a new concept called the "context". Conceptually
-speaking the context sits above the device. There is one context to many devices. The purpose of the context is to represent the backend at a more global level
-and to perform operations outside the scope of an individual device. Mainly it is used for performing run-time linking against backend libraries, initializing
-backends and enumerating devices. The example below shows how to enumerate devices.
-
- ```c
- ma_context context;
- if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) {
- // Error.
- }
-
- ma_device_info* pPlaybackInfos;
- ma_uint32 playbackCount;
- ma_device_info* pCaptureInfos;
- ma_uint32 captureCount;
- if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) {
- // Error.
- }
-
- // Loop over each device info and do something with it. Here we just print the name with their index. You may want
- // to give the user the opportunity to choose which device they'd prefer.
- for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) {
- printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name);
- }
-
- ma_device_config config = ma_device_config_init(ma_device_type_playback);
- config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id;
- config.playback.format = MY_FORMAT;
- config.playback.channels = MY_CHANNEL_COUNT;
- config.sampleRate = MY_SAMPLE_RATE;
- config.dataCallback = data_callback;
- config.pUserData = pMyCustomData;
-
- ma_device device;
- if (ma_device_init(&context, &config, &device) != MA_SUCCESS) {
- // Error
- }
-
- ...
-
- ma_device_uninit(&device);
- ma_context_uninit(&context);
- ```
-
-The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. The first parameter is a pointer to a list of `ma_backend`
-values which are used to override the default backend priorities. When this is NULL, as in this example, miniaudio's default priorities are used. The second
-parameter is the number of backends listed in the array pointed to by the first parameter. The third parameter is a pointer to a `ma_context_config` object
-which can be NULL, in which case defaults are used. The context configuration is used for setting the logging callback, custom memory allocation callbacks,
-user-defined data and some backend-specific configurations.
-
-Once the context has been initialized you can enumerate devices. In the example above we use the simpler `ma_context_get_devices()`, however you can also use a
-callback for handling devices by using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer to a pointer that will,
-upon output, be set to a pointer to a buffer containing a list of `ma_device_info` structures. You also provide a pointer to an unsigned integer that will
-receive the number of items in the returned buffer. Do not free the returned buffers as their memory is managed internally by miniaudio.
-
-The `ma_device_info` structure contains an `id` member which is the ID you pass to the device config. It also contains the name of the device which is useful
-for presenting a list of devices to the user via the UI.
-
-When creating your own context you will want to pass it to `ma_device_init()` when initializing the device. Passing in NULL, like we do in the first example,
-will result in miniaudio creating the context for you, which you don't want to do since you've already created a context. Note that internally the context is
-only tracked by it's pointer which means you must not change the location of the `ma_context` object. If this is an issue, consider using `malloc()` to
-allocate memory for the context.
-
-
-
-2. Building
-===========
-miniaudio should work cleanly out of the box without the need to download or install any dependencies. See below for platform-specific details.
-
-
-2.1. Windows
-------------
-The Windows build should compile cleanly on all popular compilers without the need to configure any include paths nor link to any libraries.
-
-2.2. macOS and iOS
-------------------
-The macOS build should compile cleanly without the need to download any dependencies nor link to any libraries or frameworks. The iOS build needs to be
-compiled as Objective-C and will need to link the relevant frameworks but should compile cleanly out of the box with Xcode. Compiling through the command line
-requires linking to `-lpthread` and `-lm`.
-
-Due to the way miniaudio links to frameworks at runtime, your application may not pass Apple's notarization process. To fix this there are two options. The
-first is to use the `MA_NO_RUNTIME_LINKING` option, like so:
-
- ```c
- #ifdef __APPLE__
- #define MA_NO_RUNTIME_LINKING
- #endif
- #define MINIAUDIO_IMPLEMENTATION
- #include "miniaudio.h"
- ```
-
-This will require linking with `-framework CoreFoundation -framework CoreAudio -framework AudioUnit`. Alternatively, if you would rather keep using runtime
-linking you can add the following to your entitlements.xcent file:
-
- ```
- <key>com.apple.security.cs.allow-dyld-environment-variables</key>
- <true/>
- <key>com.apple.security.cs.allow-unsigned-executable-memory</key>
- <true/>
- ```
-
-
-2.3. Linux
-----------
-The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any development packages.
-
-2.4. BSD
---------
-The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses sndio and FreeBSD uses OSS.
-
-2.5. Android
-------------
-AAudio is the highest priority backend on Android. This should work out of the box without needing any kind of compiler configuration. Support for AAudio
-starts with Android 8 which means older versions will fall back to OpenSL|ES which requires API level 16+.
-
-There have been reports that the OpenSL|ES backend fails to initialize on some Android based devices due to `dlopen()` failing to open "libOpenSLES.so". If
-this happens on your platform you'll need to disable run-time linking with `MA_NO_RUNTIME_LINKING` and link with -lOpenSLES.
-
-2.6. Emscripten
----------------
-The Emscripten build emits Web Audio JavaScript directly and should compile cleanly out of the box. You cannot use -std=c* compiler flags, nor -ansi.
-
-
-2.7. Build Options
-------------------
-`#define` these options before including miniaudio.h.

-
-3. Definitions
-==============
-This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity in the use of terms throughout the audio space, so this
-section is intended to clarify how miniaudio uses each term.
-
-3.1. Sample
------------
-A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit floating point number.
-
-3.2. Frame / PCM Frame
-----------------------
-A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 samples, a mono frame is 1 sample, a 5.1 surround sound frame
-is 6 samples, etc. The terms "frame" and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. If ever miniaudio
-needs to refer to a compressed frame, such as a FLAC frame, it will always clarify what it's referring to with something like "FLAC frame".
-
-3.3. Channel
-------------
-A stream of monaural audio that is emitted from an individual speaker in a speaker system, or received from an individual microphone in a microphone system. A
-stereo stream has two channels (a left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio systems refer to a channel as
-a complex audio stream that's mixed with other channels to produce the final mix - this is completely different to miniaudio's use of the term "channel" and
-should not be confused.
-
-3.4. Sample Rate
-----------------
-The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number of PCM frames that are processed per second.
-
-3.5. Formats
-------------
-Throughout miniaudio you will see references to different sample formats:
-
- +---------------+----------------------------------------+---------------------------+
- | Symbol | Description | Range |
- +---------------+----------------------------------------+---------------------------+
- | ma_format_f32 | 32-bit floating point | [-1, 1] |
- | ma_format_s16 | 16-bit signed integer | [-32768, 32767] |
- | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] |
- | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] |
- | ma_format_u8 | 8-bit unsigned integer | [0, 255] |
- +---------------+----------------------------------------+---------------------------+
-
-All formats are native-endian.
-
-
-
-4. Decoding
-===========
-The `ma_decoder` API is used for reading audio files. Decoders are completely decoupled from devices and can be used independently. The following formats are
-supported:
-
- +---------+------------------+----------+
- | Format | Decoding Backend | Built-In |
- +---------+------------------+----------+
- | WAV | dr_wav | Yes |
- | MP3 | dr_mp3 | Yes |
- | FLAC | dr_flac | Yes |
- | Vorbis | stb_vorbis | No |
- +---------+------------------+----------+
-
-Vorbis is supported via stb_vorbis which can be enabled by including the header section before the implementation of miniaudio, like the following:
-
- ```c
- #define STB_VORBIS_HEADER_ONLY
- #include "extras/stb_vorbis.c" // Enables Vorbis decoding.
-
- #define MINIAUDIO_IMPLEMENTATION
- #include "miniaudio.h"
-
- // The stb_vorbis implementation must come after the implementation of miniaudio.
- #undef STB_VORBIS_HEADER_ONLY
- #include "extras/stb_vorbis.c"
- ```
-
-A copy of stb_vorbis is included in the "extras" folder in the miniaudio repository (https://github.com/mackron/miniaudio).
-
-Built-in decoders are amalgamated into the implementation section of miniaudio. You can disable the built-in decoders by specifying one or more of the
-following options before the miniaudio implementation:
-
- ```c
- #define MA_NO_WAV
- #define MA_NO_MP3
- #define MA_NO_FLAC
- ```
-
-Disabling built-in decoding libraries is useful if you use these libraries independantly of the `ma_decoder` API.
-
-A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with `ma_decoder_init_memory()`, or from data delivered via callbacks
-with `ma_decoder_init()`. Here is an example for loading a decoder from a file:
-
- ```c
- ma_decoder decoder;
- ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder);
- if (result != MA_SUCCESS) {
- return false; // An error occurred.
- }
-
- ...
-
- ma_decoder_uninit(&decoder);
- ```
-
-When initializing a decoder, you can optionally pass in a pointer to a `ma_decoder_config` object (the `NULL` argument in the example above) which allows you
-to configure the output format, channel count, sample rate and channel map:
-
- ```c
- ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000);
- ```
-
-When passing in `NULL` for decoder config in `ma_decoder_init*()`, the output format will be the same as that defined by the decoding backend.
-
-Data is read from the decoder as PCM frames. This will return the number of PCM frames actually read. If the return value is less than the requested number of
-PCM frames it means you've reached the end:
-
- ```c
- ma_uint64 framesRead = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead);
- if (framesRead < framesToRead) {
- // Reached the end.
- }
- ```
-
-You can also seek to a specific frame like so:
-
- ```c
- ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame);
- if (result != MA_SUCCESS) {
- return false; // An error occurred.
- }
- ```
-
-If you want to loop back to the start, you can simply seek back to the first PCM frame:
-
- ```c
- ma_decoder_seek_to_pcm_frame(pDecoder, 0);
- ```
-
-When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding backend. This can be unnecessarily inefficient if the type
-is already known. In this case you can use the `_wav`, `_mp3`, etc. varients of the aforementioned initialization APIs:
-
- ```c
- ma_decoder_init_wav()
- ma_decoder_init_mp3()
- ma_decoder_init_memory_wav()
- ma_decoder_init_memory_mp3()
- ma_decoder_init_file_wav()
- ma_decoder_init_file_mp3()
- etc.
- ```
-
-The `ma_decoder_init_file()` API will try using the file extension to determine which decoding backend to prefer.
-
-
-
-5. Encoding
-===========
-The `ma_encoding` API is used for writing audio files. The only supported output format is WAV which is achieved via dr_wav which is amalgamated into the
-implementation section of miniaudio. This can be disabled by specifying the following option before the implementation of miniaudio:
-
- ```c
- #define MA_NO_WAV
- ```
-
-An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data delivered via callbacks with `ma_encoder_init()`. Below is an
-example for initializing an encoder to output to a file.
-
- ```c
- ma_encoder_config config = ma_encoder_config_init(ma_resource_format_wav, FORMAT, CHANNELS, SAMPLE_RATE);
- ma_encoder encoder;
- ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder);
- if (result != MA_SUCCESS) {
- // Error
- }
-
- ...
-
- ma_encoder_uninit(&encoder);
- ```
-
-When initializing an encoder you must specify a config which is initialized with `ma_encoder_config_init()`. Here you must specify the file type, the output
-sample format, output channel count and output sample rate. The following file types are supported:
-
- +------------------------+-------------+
- | Enum | Description |
- +------------------------+-------------+
- | ma_resource_format_wav | WAV |
- +------------------------+-------------+
-
-If the format, channel count or sample rate is not supported by the output file type an error will be returned. The encoder will not perform data conversion so
-you will need to convert it before outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the example below:
-
- ```c
- framesWritten = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite);
- ```
-
-Encoders must be uninitialized with `ma_encoder_uninit()`.
-
-
-6. Data Conversion
-==================
-A data conversion API is included with miniaudio which supports the majority of data conversion requirements. This supports conversion between sample formats,
-channel counts (with channel mapping) and sample rates.
-
-
-6.1. Sample Format Conversion
------------------------------
-Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and `ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()`
-to convert between two specific formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use `ma_convert_pcm_frames_format()` to convert
-PCM frames where you want to specify the frame count and channel count as a variable instead of the total sample count.
-
-
-6.1.1. Dithering
-----------------
-Dithering can be set using the ditherMode parameter.
-
-The different dithering modes include the following, in order of efficiency:
-
- +-----------+--------------------------+
- | Type | Enum Token |
- +-----------+--------------------------+
- | None | ma_dither_mode_none |
- | Rectangle | ma_dither_mode_rectangle |
- | Triangle | ma_dither_mode_triangle |
- +-----------+--------------------------+
-
-Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be ignored for conversions where dithering is not needed.
-Dithering is available for the following conversions:
-
- ```
- s16 -> u8
- s24 -> u8
- s32 -> u8
- f32 -> u8
- s24 -> s16
- s32 -> s16
- f32 -> s16
- ```
-
-Note that it is not an error to pass something other than ma_dither_mode_none for conversions where dither is not used. It will just be ignored.
-
-
-
-6.2. Channel Conversion
------------------------
-Channel conversion is used for channel rearrangement and conversion from one channel count to another. The `ma_channel_converter` API is used for channel
-conversion. Below is an example of initializing a simple channel converter which converts from mono to stereo.
-
- ```c
- ma_channel_converter_config config = ma_channel_converter_config_init(
- ma_format, // Sample format
- 1, // Input channels
- NULL, // Input channel map
- 2, // Output channels
- NULL, // Output channel map
- ma_channel_mix_mode_default); // The mixing algorithm to use when combining channels.
-
- result = ma_channel_converter_init(&config, &converter);
- if (result != MA_SUCCESS) {
- // Error.
- }
- ```
-
-To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so:
-
- ```c
- ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount);
- if (result != MA_SUCCESS) {
- // Error.
- }
- ```
-
-It is up to the caller to ensure the output buffer is large enough to accomodate the new PCM frames.
-
-Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported.
-
-
-6.2.1. Channel Mapping
-----------------------
-In addition to converting from one channel count to another, like the example above, the channel converter can also be used to rearrange channels. When
-initializing the channel converter, you can optionally pass in channel maps for both the input and output frames. If the channel counts are the same, and each
-channel map contains the same channel positions with the exception that they're in a different order, a simple shuffling of the channels will be performed. If,
-however, there is not a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed based on a mixing mode which is
-specified when initializing the `ma_channel_converter_config` object.
-
-When converting from mono to multi-channel, the mono channel is simply copied to each output channel. When going the other way around, the audio of each output
-channel is simply averaged and copied to the mono channel.
-
-In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess channels and silence extra channels. For example, converting
-from 4 to 2 channels, the 3rd and 4th channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and 4th channels.
-
-The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a simple distribution between input and output. Imagine sitting
-in the middle of a room, with speakers on the walls representing channel positions. The MA_CHANNEL_FRONT_LEFT position can be thought of as being in the corner
-of the front and left walls.
-
-Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined weights. Custom weights can be passed in as the last parameter of
-`ma_channel_converter_config_init()`.
-
-Predefined channel maps can be retrieved with `ma_get_standard_channel_map()`. This takes a `ma_standard_channel_map` enum as it's first parameter, which can
-be one of the following:
-
- +-----------------------------------+-----------------------------------------------------------+
- | Name | Description |
- +-----------------------------------+-----------------------------------------------------------+
- | ma_standard_channel_map_default | Default channel map used by miniaudio. See below. |
- | ma_standard_channel_map_microsoft | Channel map used by Microsoft's bitfield channel maps. |
- | ma_standard_channel_map_alsa | Default ALSA channel map. |

- | ma_standard_channel_map_webaudio | https://webaudio.github.io/web-audio-api/#ChannelOrdering |
- +-----------------------------------+-----------------------------------------------------------+
-
-Below are the channel maps used by default in miniaudio (`ma_standard_channel_map_default`):
-
- +---------------+---------------------------------+
- | Channel Count | Mapping |
- +---------------+---------------------------------+
- | 1 (Mono) | 0: MA_CHANNEL_MONO |
- +---------------+---------------------------------+
- | 2 (Stereo) | 0: MA_CHANNEL_FRONT_LEFT <br> |

- | | mapping as the device. |
- +---------------+---------------------------------+
-
-
-
-6.3. Resampling
----------------
-Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something like the following:
-
- ```c
- ma_resampler_config config = ma_resampler_config_init(
- ma_format_s16,
- channels,
- sampleRateIn,
- sampleRateOut,
- ma_resample_algorithm_linear);
-
- ma_resampler resampler;
- ma_result result = ma_resampler_init(&config, &resampler);
- if (result != MA_SUCCESS) {
- // An error occurred...
- }
- ```
-
-Do the following to uninitialize the resampler:
-
- ```c
- ma_resampler_uninit(&resampler);
- ```
-
-The following example shows how data can be processed
-
- ```c
- ma_uint64 frameCountIn = 1000;
- ma_uint64 frameCountOut = 2000;
- ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
- if (result != MA_SUCCESS) {
- // An error occurred...
- }
-
- // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the
- // number of output frames written.
- ```
-
-To initialize the resampler you first need to set up a config (`ma_resampler_config`) with `ma_resampler_config_init()`. You need to specify the sample format
-you want to use, the number of channels, the input and output sample rate, and the algorithm.
-
-The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format you will need to perform pre- and post-conversions yourself
-where necessary. Note that the format is the same for both input and output. The format cannot be changed after initialization.
-
-The resampler supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
-
-The sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the
-only configuration property that can be changed after initialization.
-
-The miniaudio resampler supports multiple algorithms:
-
- +-----------+------------------------------+
- | Algorithm | Enum Token |
- +-----------+------------------------------+
- | Linear | ma_resample_algorithm_linear |
- | Speex | ma_resample_algorithm_speex |
- +-----------+------------------------------+
-
-Because Speex is not public domain it is strictly opt-in and the code is stored in separate files. if you opt-in to the Speex backend you will need to consider
-it's license, the text of which can be found in it's source files in "extras/speex_resampler". Details on how to opt-in to the Speex resampler is explained in
-the Speex Resampler section below.
-
-The algorithm cannot be changed after initialization.
-
-Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
-frames, use `ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number of
-input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
-number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
-buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
-
-The sample rate can be changed dynamically on the fly. You can change this with explicit sample rates with `ma_resampler_set_rate()` and also with a decimal
-ratio with `ma_resampler_set_rate_ratio()`. The ratio is in/out.
-
-Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
-`ma_resampler_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
-input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`.
-
-Due to the nature of how resampling works, the resampler introduces some latency. This can be retrieved in terms of both the input rate and the output rate
-with `ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`.
-
-
-6.3.1. Resampling Algorithms
-----------------------------
-The choice of resampling algorithm depends on your situation and requirements. The linear resampler is the most efficient and has the least amount of latency,
-but at the expense of poorer quality. The Speex resampler is higher quality, but slower with more latency. It also performs several heap allocations internally
-for memory management.
-
-
-6.3.1.1. Linear Resampling
---------------------------
-The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, some control over the quality of the linear resampler which
-may make it a suitable option depending on your requirements.
-
-The linear resampler performs low-pass filtering before or after downsampling or upsampling, depending on the sample rates you're converting between. When
-decreasing the sample rate, the low-pass filter will be applied before downsampling. When increasing the rate it will be performed after upsampling. By default
-a fourth order low-pass filter will be applied. This can be configured via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering.
-
-The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of the input and output sample rates (Nyquist Frequency). This
-can be controlled with the `lpfNyquistFactor` config variable. This defaults to 1, and should be in the range of 0..1, although a value of 0 does not make
-sense and should be avoided. A value of 1 will use the Nyquist Frequency as the cutoff. A value of 0.5 will use half the Nyquist Frequency as the cutoff, etc.
-Values less than 1 will result in more washed out sound due to more of the higher frequencies being removed. This config variable has no impact on performance
-and is a purely perceptual configuration.
-
-The API for the linear resampler is the same as the main resampler API, only it's called `ma_linear_resampler`.
-
-
-6.3.1.2. Speex Resampling
--------------------------
-The Speex resampler is made up of third party code which is released under the BSD license. Because it is licensed differently to miniaudio, which is public
-domain, it is strictly opt-in and all of it's code is stored in separate files. If you opt-in to the Speex resampler you must consider the license text in it's
-source files. To opt-in, you must first `#include` the following file before the implementation of miniaudio.h:
-
- ```c
- #include "extras/speex_resampler/ma_speex_resampler.h"
- ```
-
-Both the header and implementation is contained within the same file. The implementation can be included in your program like so:
-
- ```c
- #define MINIAUDIO_SPEEX_RESAMPLER_IMPLEMENTATION
- #include "extras/speex_resampler/ma_speex_resampler.h"
- ```
-
-Note that even if you opt-in to the Speex backend, miniaudio won't use it unless you explicitly ask for it in the respective config of the object you are
-initializing. If you try to use the Speex resampler without opting in, initialization of the `ma_resampler` object will fail with `MA_NO_BACKEND`.
-
-The only configuration option to consider with the Speex resampler is the `speex.quality` config variable. This is a value between 0 and 10, with 0 being
-the fastest with the poorest quality and 10 being the slowest with the highest quality. The default value is 3.
-
-
-
-6.4. General Data Conversion
-----------------------------
-The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and resampling into one operation. This is what miniaudio uses
-internally to convert between the format requested when the device was initialized and the format of the backend's native device. The API for general data
-conversion is very similar to the resampling API. Create a `ma_data_converter` object like this:
-
- ```c
- ma_data_converter_config config = ma_data_converter_config_init(
- inputFormat,
- outputFormat,
- inputChannels,
- outputChannels,
- inputSampleRate,
- outputSampleRate
- );
-
- ma_data_converter converter;
- ma_result result = ma_data_converter_init(&config, &converter);
- if (result != MA_SUCCESS) {
- // An error occurred...
- }
- ```
-
-In the example above we use `ma_data_converter_config_init()` to initialize the config, however there's many more properties that can be configured, such as
-channel maps and resampling quality. Something like the following may be more suitable depending on your requirements:
-
- ```c
- ma_data_converter_config config = ma_data_converter_config_init_default();
- config.formatIn = inputFormat;
- config.formatOut = outputFormat;
- config.channelsIn = inputChannels;
- config.channelsOut = outputChannels;
- config.sampleRateIn = inputSampleRate;
- config.sampleRateOut = outputSampleRate;
- ma_get_standard_channel_map(ma_standard_channel_map_flac, config.channelCountIn, config.channelMapIn);
- config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER;
- ```
-
-Do the following to uninitialize the data converter:
-
- ```c
- ma_data_converter_uninit(&converter);
- ```
-
-The following example shows how data can be processed
-
- ```c
- ma_uint64 frameCountIn = 1000;
- ma_uint64 frameCountOut = 2000;
- ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
- if (result != MA_SUCCESS) {
- // An error occurred...
- }
-
- // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number
- // of output frames written.
- ```
-
-The data converter supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
-
-Sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the only
-configuration property that can be changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of `ma_data_converter_config` is
-set to `MA_TRUE`. To change the sample rate, use `ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. The
-resampling algorithm cannot be changed after initialization.
-
-Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
-frames, use `ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number
-of input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
-number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
-buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
-
-Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
-`ma_data_converter_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
-input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`.
-
-Due to the nature of how resampling works, the data converter introduces some latency if resampling is required. This can be retrieved in terms of both the
-input rate and the output rate with `ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`.
-
-
-
-7. Filtering
-============
-
-7.1. Biquad Filtering
----------------------
-Biquad filtering is achieved with the `ma_biquad` API. Example:
-
- ```c
- ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2);
- ma_result result = ma_biquad_init(&config, &biquad);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount);
- ```
-
-Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, b1 and b2, and the denominator coefficients are a0, a1 and
-a2. The a0 coefficient is required and coefficients must not be pre-normalized.
-
-Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. When using
-`ma_format_s16` the biquad filter will use fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used.
-
-Input and output frames are always interleaved.
-
-Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
-
- ```c
- ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount);
- ```
-
-If you need to change the values of the coefficients, but maintain the values in the registers you can do so with `ma_biquad_reinit()`. This is useful if you
-need to change the properties of the filter while keeping the values of registers valid to avoid glitching. Do not use `ma_biquad_init()` for this as it will
-do a full initialization which involves clearing the registers to 0. Note that changing the format or channel count after initialization is invalid and will
-result in an error.
-
-
-7.2. Low-Pass Filtering
------------------------
-Low-pass filtering is achieved with the following APIs:
-
- +---------+------------------------------------------+
- | API | Description |
- +---------+------------------------------------------+
- | ma_lpf1 | First order low-pass filter |
- | ma_lpf2 | Second order low-pass filter |
- | ma_lpf | High order low-pass filter (Butterworth) |
- +---------+------------------------------------------+
-
-Low-pass filter example:
-
- ```c
- ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order);
- ma_result result = ma_lpf_init(&config, &lpf);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount);
- ```
-
-Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. Input and output
-frames are always interleaved.
-
-Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
-
- ```c
- ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount);
- ```
-
-The maximum filter order is limited to `MA_MAX_FILTER_ORDER` which is set to 8. If you need more, you can chain first and second order filters together.
-
- ```c
- for (iFilter = 0; iFilter < filterCount; iFilter += 1) {
- ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount);
- }
- ```
-
-If you need to change the configuration of the filter, but need to maintain the state of internal registers you can do so with `ma_lpf_reinit()`. This may be
-useful if you need to change the sample rate and/or cutoff frequency dynamically while maintaing smooth transitions. Note that changing the format or channel
-count after initialization is invalid and will result in an error.
-
-The `ma_lpf` object supports a configurable order, but if you only need a first order filter you may want to consider using `ma_lpf1`. Likewise, if you only
-need a second order filter you can use `ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient.
-
-If an even filter order is specified, a series of second order filters will be processed in a chain. If an odd filter order is specified, a first order filter
-will be applied, followed by a series of second order filters in a chain.
-
-
-7.3. High-Pass Filtering
-------------------------
-High-pass filtering is achieved with the following APIs:
-
- +---------+-------------------------------------------+
- | API | Description |
- +---------+-------------------------------------------+
- | ma_hpf1 | First order high-pass filter |
- | ma_hpf2 | Second order high-pass filter |
- | ma_hpf | High order high-pass filter (Butterworth) |
- +---------+-------------------------------------------+
-
-High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, `ma_hpf2` and `ma_hpf`. See example code for low-pass filters
-for example usage.
-
-
-7.4. Band-Pass Filtering
-------------------------
-Band-pass filtering is achieved with the following APIs:
-
- +---------+-------------------------------+
- | API | Description |
- +---------+-------------------------------+
- | ma_bpf2 | Second order band-pass filter |
- | ma_bpf | High order band-pass filter |
- +---------+-------------------------------+
-
-Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and `ma_hpf`. See example code for low-pass filters for example
-usage. Note that the order for band-pass filters must be an even number which means there is no first order band-pass filter, unlike low-pass and high-pass
-filters.
-
-
-7.5. Notch Filtering
---------------------
-Notch filtering is achieved with the following APIs:
-
- +-----------+------------------------------------------+
- | API | Description |
- +-----------+------------------------------------------+
- | ma_notch2 | Second order notching filter |
- +-----------+------------------------------------------+
-
-
-7.6. Peaking EQ Filtering
--------------------------
-Peaking filtering is achieved with the following APIs:
-
- +----------+------------------------------------------+
- | API | Description |
- +----------+------------------------------------------+
- | ma_peak2 | Second order peaking filter |
- +----------+------------------------------------------+
-
-
-7.7. Low Shelf Filtering
-------------------------
-Low shelf filtering is achieved with the following APIs:
-
- +-------------+------------------------------------------+
- | API | Description |
- +-------------+------------------------------------------+
- | ma_loshelf2 | Second order low shelf filter |
- +-------------+------------------------------------------+
-
-Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to just turn them down rather than eliminate them entirely.
-
-
-7.8. High Shelf Filtering
--------------------------
-High shelf filtering is achieved with the following APIs:
-
- +-------------+------------------------------------------+
- | API | Description |
- +-------------+------------------------------------------+
- | ma_hishelf2 | Second order high shelf filter |
- +-------------+------------------------------------------+
-
-The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` instead of `ma_loshelf`. Where a low shelf filter is used to
-adjust the volume of low frequencies, the high shelf filter does the same thing for high frequencies.
-
-
-
-
-8. Waveform and Noise Generation
-================================
-
-8.1. Waveforms
---------------
-miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved with the `ma_waveform` API. Example:
-
- ```c
- ma_waveform_config config = ma_waveform_config_init(
- FORMAT,
- CHANNELS,
- SAMPLE_RATE,
- ma_waveform_type_sine,
- amplitude,
- frequency);
-
- ma_waveform waveform;
- ma_result result = ma_waveform_init(&config, &waveform);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount);
- ```
-
-The amplitude, frequency, type, and sample rate can be changed dynamically with `ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()`,
-`ma_waveform_set_type()`, and `ma_waveform_set_sample_rate()` respectively.
-
-You can invert the waveform by setting the amplitude to a negative value. You can use this to control whether or not a sawtooth has a positive or negative
-ramp, for example.
-
-Below are the supported waveform types:
-
- +---------------------------+
- | Enum Name |
- +---------------------------+
- | ma_waveform_type_sine |
- | ma_waveform_type_square |
- | ma_waveform_type_triangle |
- | ma_waveform_type_sawtooth |
- +---------------------------+
-
-
-
-8.2. Noise
-----------
-miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example:
-
- ```c
- ma_noise_config config = ma_noise_config_init(
- FORMAT,
- CHANNELS,
- ma_noise_type_white,
- SEED,
- amplitude);
-
- ma_noise noise;
- ma_result result = ma_noise_init(&config, &noise);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_noise_read_pcm_frames(&noise, pOutput, frameCount);
- ```
-
-The noise API uses simple LCG random number generation. It supports a custom seed which is useful for things like automated testing requiring reproducibility.
-Setting the seed to zero will default to `MA_DEFAULT_LCG_SEED`.
-
-The amplitude, seed, and type can be changed dynamically with `ma_noise_set_amplitude()`, `ma_noise_set_seed()`, and `ma_noise_set_type()` respectively.
-
-By default, the noise API will use different values for different channels. So, for example, the left side in a stereo stream will be different to the right
-side. To instead have each channel use the same random value, set the `duplicateChannels` member of the noise config to true, like so:
-
- ```c
- config.duplicateChannels = MA_TRUE;
- ```
-
-Below are the supported noise types.
-
- +------------------------+
- | Enum Name |
- +------------------------+
- | ma_noise_type_white |
- | ma_noise_type_pink |
- | ma_noise_type_brownian |
- +------------------------+
-
-
-
-9. Audio Buffers
-================
-miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can read from memory that's managed by the application, but
-can also handle the memory management for you internally. Memory management is flexible and should support most use cases.
-
-Audio buffers are initialised using the standard configuration system used everywhere in miniaudio:
-
- ```c
- ma_audio_buffer_config config = ma_audio_buffer_config_init(
- format,
- channels,
- sizeInFrames,
- pExistingData,
- &allocationCallbacks);
-
- ma_audio_buffer buffer;
- result = ma_audio_buffer_init(&config, &buffer);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_audio_buffer_uninit(&buffer);
- ```
-
-In the example above, the memory pointed to by `pExistingData` will *not* be copied and is how an application can do self-managed memory allocation. If you
-would rather make a copy of the data, use `ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`.
-
-Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure and the raw audio data in a contiguous block of memory. That is,
-the raw audio data will be located immediately after the `ma_audio_buffer` structure. To do this, use `ma_audio_buffer_alloc_and_init()`:
-
- ```c
- ma_audio_buffer_config config = ma_audio_buffer_config_init(
- format,
- channels,
- sizeInFrames,
- pExistingData,
- &allocationCallbacks);
-
- ma_audio_buffer* pBuffer
- result = ma_audio_buffer_alloc_and_init(&config, &pBuffer);
- if (result != MA_SUCCESS) {
- // Error
- }
-
- ...
-
- ma_audio_buffer_uninit_and_free(&buffer);
- ```
-
-If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it with `ma_audio_buffer_uninit_and_free()`. In the example above,
-the memory pointed to by `pExistingData` will be copied into the buffer, which is contrary to the behavior of `ma_audio_buffer_init()`.
-
-An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the cursor moves forward. The last parameter (`loop`) can be
-used to determine if the buffer should loop. The return value is the number of frames actually read. If this is less than the number of frames requested it
-means the end has been reached. This should never happen if the `loop` parameter is set to true. If you want to manually loop back to the start, you can do so
-with with `ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an audio buffer.
-
- ```c
- ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping);
- if (framesRead < desiredFrameCount) {
- // If not looping, this means the end has been reached. This should never happen in looping mode with valid input.
- }
- ```
-
-Sometimes you may want to avoid the cost of data movement between the internal buffer and the output buffer. Instead you can use memory mapping to retrieve a
-pointer to a segment of data:
-
- ```c
- void* pMappedFrames;
- ma_uint64 frameCount = frameCountToTryMapping;
- ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount);
- if (result == MA_SUCCESS) {
- // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be
- // less due to the end of the buffer being reached.
- ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels);
-
- // You must unmap the buffer.
- ma_audio_buffer_unmap(pAudioBuffer, frameCount);
- }
- ```
-
-When you use memory mapping, the read cursor is increment by the frame count passed in to `ma_audio_buffer_unmap()`. If you decide not to process every frame
-you can pass in a value smaller than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is that it does not handle looping
-for you. You can determine if the buffer is at the end for the purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of
-`ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` as an error when returned by `ma_audio_buffer_unmap()`.
-
-
-
-10. Ring Buffers
-================
-miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates
-on bytes, whereas the `ma_pcm_rb` operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around `ma_rb`.
-
-Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved streams. The caller can also allocate their own backing memory for
-the ring buffer to use internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for you.
-
-The examples below use the PCM frame variant of the ring buffer since that's most likely the one you will want to use. To initialize a ring buffer, do
-something like the following:
-
- ```c
- ma_pcm_rb rb;
- ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb);
- if (result != MA_SUCCESS) {
- // Error
- }
- ```
-
-The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because it's the PCM varient of the ring buffer API. For the regular
-ring buffer that operates on bytes you would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes instead of frames. The
-fourth parameter is an optional pre-allocated buffer and the fifth parameter is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation
-routines. Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used.
-
-Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is offset from each other based on the stride. To manage your
-sub-buffers you can use `ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and `ma_pcm_rb_get_subbuffer_ptr()`.
-
-Use `ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section of the ring buffer. You specify the number of frames you
-need, and on output it will set to what was actually acquired. If the read or write pointer is positioned such that the number of frames requested will require
-a loop, it will be clamped to the end of the buffer. Therefore, the number of frames you're given may be less than the number you requested.
-
-After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the buffer and then "commit" it with `ma_pcm_rb_commit_read()` or
-`ma_pcm_rb_commit_write()`. This is where the read/write pointers are updated. When you commit you need to pass in the buffer that was returned by the earlier
-call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and
-`ma_pcm_rb_commit_write()` is what's used to increment the pointers, and can be less that what was originally requested.
-
-If you want to correct for drift between the write pointer and the read pointer you can use a combination of `ma_pcm_rb_pointer_distance()`,
-`ma_pcm_rb_seek_read()` and `ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only move the read pointer forward via
-the consumer thread, and the write pointer forward by the producer thread. If there is too much space between the pointers, move the read pointer forward. If
-there is too little space between the pointers, move the write pointer forward.
-
-You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` API. This is exactly the same, only you will use the `ma_rb`
-functions instead of `ma_pcm_rb` and instead of frame counts you will pass around byte counts.
-
-The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most significant bit being used to encode a loop flag and the internally
-managed buffers always being aligned to MA_SIMD_ALIGNMENT.
-
-Note that the ring buffer is only thread safe when used by a single consumer thread and single producer thread.
-

-11. Backends
-============
-The following backends are supported by miniaudio.
-
- +-------------+-----------------------+--------------------------------------------------------+
- | Name | Enum Name | Supported Operating Systems |
- +-------------+-----------------------+--------------------------------------------------------+
- | WASAPI | ma_backend_wasapi | Windows Vista+ |
- | DirectSound | ma_backend_dsound | Windows XP+ |
- | WinMM | ma_backend_winmm | Windows XP+ (may work on older versions, but untested) |
- | Core Audio | ma_backend_coreaudio | macOS, iOS |
- | ALSA | ma_backend_alsa | Linux |
- | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) |
- | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) |
- | sndio | ma_backend_sndio | OpenBSD |
- | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD |
- | OSS | ma_backend_oss | FreeBSD |
- | AAudio | ma_backend_aaudio | Android 8+ |
- | OpenSL ES | ma_backend_opensl | Android (API level 16+) |
- | Web Audio | ma_backend_webaudio | Web (via Emscripten) |
- | Custom | ma_backend_custom | Cross Platform |
- | Null | ma_backend_null | Cross Platform (not used on Web) |
- +-------------+-----------------------+--------------------------------------------------------+
-
-Some backends have some nuance details you may want to be aware of.
-
-11.1. WASAPI
-------------
-- Low-latency shared mode will be disabled when using an application-defined sample rate which is different to the device's native sample rate. To work around
- this, set `wasapi.noAutoConvertSRC` to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing when the
- `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC will result in miniaudio's internal resampler being used instead
- which will in turn enable the use of low-latency shared mode.
-
-11.2. PulseAudio
-----------------
-- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki:
- https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. Alternatively, consider using a different backend such as ALSA.
-
-11.3. Android
--------------
-- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: `<uses-permission android:name="android.permission.RECORD_AUDIO" />`
-- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a limitation with OpenSL|ES.
-- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration API (devices are enumerated through Java). You can however
- perform your own device enumeration through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it to ma_device_init().
-- The backend API will perform resampling where possible. The reason for this as opposed to using miniaudio's built-in resampler is to take advantage of any
- potential device-specific optimizations the driver may implement.
-
-11.4. UWP
----------
-- UWP only supports default playback and capture devices.
-- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest):
-
- ```
- <Package ...>
- ...
- <Capabilities>
- <DeviceCapability Name="microphone" />
- </Capabilities>
- </Package>
- ```
-
-11.5. Web Audio / Emscripten
-----------------------------
-- You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build.
-- The first time a context is initialized it will create a global object called "miniaudio" whose primary purpose is to act as a factory for device objects.
-- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as they've been deprecated.
-- Google has implemented a policy in their browsers that prevent automatic media output without first receiving some kind of user input. The following web page
- has additional details: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device may fail if you try to start playback
- without first handling some kind of user input.
-
-
-
-12. Miscellaneous Notes
-=======================
-- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for WASAPI and Core Audio, however other backends such as
- PulseAudio may naturally support it, though not all have been tested.
-- The contents of the output buffer passed into the data callback will always be pre-initialized to silence unless the `noPreZeroedOutputBuffer` config variable
- in `ma_device_config` is set to true, in which case it'll be undefined which will require you to write something to the entire buffer.
-- By default miniaudio will automatically clip samples. This only applies when the playback sample format is configured as `ma_format_f32`. If you are doing
- clipping yourself, you can disable this overhead by setting `noClip` to true in the device config.
-- The sndio backend is currently only enabled on OpenBSD builds.
-- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can use it.
-- Note that GCC and Clang requires `-msse2`, `-mavx2`, etc. for SIMD optimizations.
-- When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This is due to 64-bit file APIs not being available.

-Logging Levels
-==============
-A log level will automatically include the lower levels. For example, verbose logging will enable everything. The warning log level will only include warnings
-and errors, but will ignore informational and verbose logging. If you only want to handle a specific log level, implement a custom log callback (see
-ma_context_init() for details) and interrogate the `logLevel` parameter.
-
-By default the log level will be set to MA_LOG_LEVEL_ERROR, but you can change this by defining MA_LOG_LEVEL before the implementation of miniaudio.
-
-MA_LOG_LEVEL_VERBOSE
- Mainly intended for debugging. This will enable all log levels and can be triggered from within the data callback so care must be taken when enabling this
- in production environments.
-
-MA_LOG_LEVEL_INFO
- Informational logging. Useful for debugging. This will also enable warning and error logs. This will never be called from within the data callback.
-
-MA_LOG_LEVEL_WARNING
- Warnings. You should enable this in you development builds and action them when encounted. This will also enable error logs. These logs usually indicate a
- potential problem or misconfiguration, but still allow you to keep running. This will never be called from within the data callback.
-
-MA_LOG_LEVEL_ERROR
- Error logging. This will be fired when an operation fails and is subsequently aborted. This can be fired from within the data callback, in which case the
- device will be stopped. You should always have this log level enabled.

-The callback for processing audio data from the device.
-
-The data callback is fired by miniaudio whenever the device needs to have more data delivered to a playback device, or when a capture device has some data
-available. This is called as soon as the backend asks for more data which means it may be called with inconsistent frame counts. You cannot assume the
-callback will be fired with a consistent frame count.
-
-
-Parameters
-----------
-pDevice (in)
- A pointer to the relevant device.
-
-pOutput (out)
- A pointer to the output buffer that will receive audio data that will later be played back through the speakers. This will be non-null for a playback or
- full-duplex device and null for a capture and loopback device.
-
-pInput (in)
- A pointer to the buffer containing input data from a recording device. This will be non-null for a capture, full-duplex or loopback device and null for a
- playback device.
-
-frameCount (in)
- The number of PCM frames to process. Note that this will not necessarily be equal to what you requested when you initialized the device. The
- `periodSizeInFrames` and `periodSizeInMilliseconds` members of the device config are just hints, and are not necessarily exactly what you'll get. You must
- not assume this will always be the same value each time the callback is fired.
-
-
-Remarks
--------
-You cannot stop and start the device from inside the callback or else you'll get a deadlock. You must also not uninitialize the device from inside the
-callback. The following APIs cannot be called from inside the callback:
-
- ma_device_init()
- ma_device_init_ex()
- ma_device_uninit()
- ma_device_start()
- ma_device_stop()
-
-The proper way to stop the device is to call `ma_device_stop()` from a different thread, normally the main application thread.

-/*
-These are the callbacks required to be implemented for a backend. These callbacks are grouped into two parts: context and device. There is one context
-to many devices. A device is created from a context.
-
-The general flow goes like this:
-
- 1) A context is created with `onContextInit()`
- 1a) Available devices can be enumerated with `onContextEnumerateDevices()` if required.
- 1b) Detailed information about a device can be queried with `onContextGetDeviceInfo()` if required.
- 2) A device is created from the context that was created in the first step using `onDeviceInit()`, and optionally a device ID that was
- selected from device enumeration via `onContextEnumerateDevices()`.
- 3) A device is started or stopped with `onDeviceStart()` / `onDeviceStop()`
- 4) Data is delivered to and from the device by the backend. This is always done based on the native format returned by the prior call
- to `onDeviceInit()`. Conversion between the device's native format and the format requested by the application will be handled by
- miniaudio internally.
-
-Initialization of the context is quite simple. You need to do any necessary initialization of internal objects and then output the
-callbacks defined in this structure.
-
-Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which
-physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the
-given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration
-needs to stop and the `onContextEnumerateDevices()` function return with a success code.
-
-Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID,
-and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the
-case when the device ID is NULL, in which case information about the default device needs to be retrieved.
-
-Once the context has been created and the device ID retrieved (if using anything other than the default device), the device can be created.
-This is a little bit more complicated than initialization of the context due to it's more complicated configuration. When initializing a
-device, a duplex device may be requested. This means a separate data format needs to be specified for both playback and capture. On input,
-the data format is set to what the application wants. On output it's set to the native format which should match as closely as possible to
-the requested format. The conversion between the format requested by the application and the device's native format will be handled
-internally by miniaudio.
-
-On input, if the sample format is set to `ma_format_unknown`, the backend is free to use whatever sample format it desires, so long as it's
-supported by miniaudio. When the channel count is set to 0, the backend should use the device's native channel count. The same applies for
-sample rate. For the channel map, the default should be used when `ma_channel_map_blank()` returns true (all channels set to
-`MA_CHANNEL_NONE`). On input, the `periodSizeInFrames` or `periodSizeInMilliseconds` option should always be set. The backend should
-inspect both of these variables. If `periodSizeInFrames` is set, it should take priority, otherwise it needs to be derived from the period
-size in milliseconds (`periodSizeInMilliseconds`) and the sample rate, keeping in mind that the sample rate may be 0, in which case the
-sample rate will need to be determined before calculating the period size in frames. On output, all members of the `ma_device_data_format`
-object should be set to a valid value, except for `periodSizeInMilliseconds` which is optional (`periodSizeInFrames` *must* be set).
-
-Starting and stopping of the device is done with `onDeviceStart()` and `onDeviceStop()` and should be self-explanatory. If the backend uses
-asynchronous reading and writing, `onDeviceStart()` and `onDeviceStop()` should always be implemented.
-
-The handling of data delivery between the application and the device is the most complicated part of the process. To make this a bit
-easier, some helper callbacks are available. If the backend uses a blocking read/write style of API, the `onDeviceRead()` and
-`onDeviceWrite()` callbacks can optionally be implemented. These are blocking and work just like reading and writing from a file. If the
-backend uses a callback for data delivery, that callback must call `ma_device_handle_backend_data_callback()` from within it's callback.
-This allows miniaudio to then process any necessary data conversion and then pass it to the miniaudio data callback.
-
-If the backend requires absolute flexibility with it's data delivery, it can optionally implement the `onDeviceWorkerThread()` callback
-which will allow it to implement the logic that will run on the audio thread. This is much more advanced and is completely optional.
-
-The audio thread should run data delivery logic in a loop while `ma_device_get_state() == MA_STATE_STARTED` and no errors have been
-encounted. Do not start or stop the device here. That will be handled from outside the `onDeviceDataLoop()` callback.
-
-The invocation of the `onDeviceDataLoop()` callback will be handled by miniaudio. When you start the device, miniaudio will fire this
-callback. When the device is stopped, the `ma_device_get_state() == MA_STATE_STARTED` condition will fail and the loop will be terminated
-which will then fall through to the part that stops the device. For an example on how to implement the `onDeviceDataLoop()` callback,
-look at `ma_device_audio_thread__default_read_write()`. Implement the `onDeviceDataLoopWakeup()` callback if you need a mechanism to
-wake up the audio thread.

-Initializes a `ma_context_config` object.
-
-
-Return Value
-------------
-A `ma_context_config` initialized to defaults.
-
-
-Remarks
--------
-You must always use this to initialize the default state of the `ma_context_config` object. Not using this will result in your program breaking when miniaudio
-is updated and new members are added to `ma_context_config`. It also sets logical defaults.
-
-You can override members of the returned object by changing it's members directly.

-Initializes a context.
-
-The context is used for selecting and initializing an appropriate backend and to represent the backend at a more global level than that of an individual
-device. There is one context to many devices, and a device is created from a context. A context is required to enumerate devices.
-
-
-Parameters
-----------
-backends (in, optional)
- A list of backends to try initializing, in priority order. Can be NULL, in which case it uses default priority order.
-
-backendCount (in, optional)
- The number of items in `backend`. Ignored if `backend` is NULL.
-
-pConfig (in, optional)
- The context configuration.
-
-pContext (in)
- A pointer to the context object being initialized.
-
-
-Return Value
-------------
-MA_SUCCESS if successful; any other error code otherwise.
-
-
-Thread Safety
--------------
-Unsafe. Do not call this function across multiple threads as some backends read and write to global state.
-
-
-Remarks
--------
-When `backends` is NULL, the default priority order will be used. Below is a list of backends in priority order:
-
- |-------------|-----------------------|--------------------------------------------------------|
- | Name | Enum Name | Supported Operating Systems |
- |-------------|-----------------------|--------------------------------------------------------|
- | WASAPI | ma_backend_wasapi | Windows Vista+ |
- | DirectSound | ma_backend_dsound | Windows XP+ |
- | WinMM | ma_backend_winmm | Windows XP+ (may work on older versions, but untested) |
- | Core Audio | ma_backend_coreaudio | macOS, iOS |
- | ALSA | ma_backend_alsa | Linux |
- | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) |
- | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) |
- | sndio | ma_backend_sndio | OpenBSD |
- | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD |
- | OSS | ma_backend_oss | FreeBSD |
- | AAudio | ma_backend_aaudio | Android 8+ |
- | OpenSL|ES | ma_backend_opensl | Android (API level 16+) |
- | Web Audio | ma_backend_webaudio | Web (via Emscripten) |
- | Null | ma_backend_null | Cross Platform (not used on Web) |
- |-------------|-----------------------|--------------------------------------------------------|
-
-The context can be configured via the `pConfig` argument. The config object is initialized with `ma_context_config_init()`. Individual configuration settings
-can then be set directly on the structure. Below are the members of the `ma_context_config` object.
-
- logCallback
- Callback for handling log messages from miniaudio.
-
- threadPriority
- The desired priority to use for the audio thread. Allowable values include the following:
-
- |--------------------------------------|
- | Thread Priority |
- |--------------------------------------|
- | ma_thread_priority_idle |
- | ma_thread_priority_lowest |
- | ma_thread_priority_low |
- | ma_thread_priority_normal |
- | ma_thread_priority_high |
- | ma_thread_priority_highest (default) |
- | ma_thread_priority_realtime |
- | ma_thread_priority_default |
- |--------------------------------------|
-
- pUserData
- A pointer to application-defined data. This can be accessed from the context object directly such as `context.pUserData`.
-
- allocationCallbacks
- Structure containing custom allocation callbacks. Leaving this at defaults will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. These allocation
- callbacks will be used for anything tied to the context, including devices.
-
- alsa.useVerboseDeviceEnumeration
- ALSA will typically enumerate many different devices which can be intrusive and not user-friendly. To combat this, miniaudio will enumerate only unique
- card/device pairs by default. The problem with this is that you lose a bit of flexibility and control. Setting alsa.useVerboseDeviceEnumeration makes
- it so the ALSA backend includes all devices. Defaults to false.
-
- pulse.pApplicationName
- PulseAudio only. The application name to use when initializing the PulseAudio context with `pa_context_new()`.
-
- pulse.pServerName
- PulseAudio only. The name of the server to connect to with `pa_context_connect()`.
-
- pulse.tryAutoSpawn
- PulseAudio only. Whether or not to try automatically starting the PulseAudio daemon. Defaults to false. If you set this to true, keep in mind that
- miniaudio uses a trial and error method to find the most appropriate backend, and this will result in the PulseAudio daemon starting which may be
- intrusive for the end user.
-
- coreaudio.sessionCategory
- iOS only. The session category to use for the shared AudioSession instance. Below is a list of allowable values and their Core Audio equivalents.
-
- |-----------------------------------------|-------------------------------------|
- | miniaudio Token | Core Audio Token |
- |-----------------------------------------|-------------------------------------|
- | ma_ios_session_category_ambient | AVAudioSessionCategoryAmbient |
- | ma_ios_session_category_solo_ambient | AVAudioSessionCategorySoloAmbient |

-
-It is recommended that only a single context is active at any given time because it's a bulky data structure which performs run-time linking for the
-relevant backends every time it's initialized.
-
-The location of the context cannot change throughout it's lifetime. Consider allocating the `ma_context` object with `malloc()` if this is an issue. The
-reason for this is that a pointer to the context is stored in the `ma_device` structure.
-
-
-Example 1 - Default Initialization
-----------------------------------
-The example below shows how to initialize the context using the default configuration.
-
-```c
-ma_context context;
-ma_result result = ma_context_init(NULL, 0, NULL, &context);
-if (result != MA_SUCCESS) {
- // Error.
-}
-```
-
-
-Example 2 - Custom Configuration
---------------------------------
-The example below shows how to initialize the context using custom backend priorities and a custom configuration. In this hypothetical example, the program
-wants to prioritize ALSA over PulseAudio on Linux. They also want to avoid using the WinMM backend on Windows because it's latency is too high. They also
-want an error to be returned if no valid backend is available which they achieve by excluding the Null backend.
-
-For the configuration, the program wants to capture any log messages so they can, for example, route it to a log file and user interface.
-
-```c
-ma_backend backends[] = {
- ma_backend_alsa,
- ma_backend_pulseaudio,
- ma_backend_wasapi,
- ma_backend_dsound
-};
-
-ma_context_config config = ma_context_config_init();
-config.logCallback = my_log_callback;
-config.pUserData = pMyUserData;
-
-ma_context context;
-ma_result result = ma_context_init(backends, sizeof(backends)/sizeof(backends[0]), &config, &context);
-if (result != MA_SUCCESS) {
- // Error.
- if (result == MA_NO_BACKEND) {
- // Couldn't find an appropriate backend.
- }
-}
-```

-
-Note that this only retrieves the ID and name/description of the device. The reason for only retrieving basic information is that it would otherwise require

-Initializes a device.
-
-A device represents a physical audio device. The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it
-from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be
-playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the
-device is done via a callback which is fired by miniaudio at periodic time intervals.
-
-The frequency at which data is delivered to and from a device depends on the size of it's period. The size of the period can be defined in terms of PCM frames
-or milliseconds, whichever is more convenient. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and
-increased risk of glitching due to the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but
-miniaudio's defaults should work fine for most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple
-media player you can make it larger. Note that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the
-backend is ultimately responsible for what it gives you. You cannot assume you will get exactly what you ask for.
-
-When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the
-format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you
-can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline.
-
-
-Parameters
-----------
-pContext (in, optional)
- A pointer to the context that owns the device. This can be null, in which case it creates a default context internally.
-
-pConfig (in)
- A pointer to the device configuration. Cannot be null. See remarks for details.
-
-pDevice (out)
- A pointer to the device object being initialized.
-
-
-Return Value
-------------
-MA_SUCCESS if successful; any other error code otherwise.
-
-
-Thread Safety
--------------
-Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to
-calling this at the same time as `ma_device_uninit()`.
-
-
-Callback Safety
----------------
-Unsafe. It is not safe to call this inside any callback.
-
-
-Remarks
--------
-Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so:
-
- ```c
- ma_context_init(NULL, 0, NULL, &context);
- ```
-
-Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use
-device.pContext for the initialization of other devices.
-
-The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can
-then be set directly on the structure. Below are the members of the `ma_device_config` object.
-
- deviceType
- Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`.
-
- sampleRate
- The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate.
-
- periodSizeInFrames
- The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will
- be used depending on the selected performance profile. This value affects latency. See below for details.
-
- periodSizeInMilliseconds
- The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be
- used depending on the selected performance profile. The value affects latency. See below for details.
-
- periods
- The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by
- this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured.
-
- performanceProfile
- A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or
- `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value.
-
- noPreZeroedOutputBuffer
- When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of
- the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data
- callback will write to every sample in the output buffer, or if you are doing your own clearing.
-
- noClip
- When set to true, the contents of the output buffer passed into the data callback will be clipped after returning. When set to false (default), the
- contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or not the clip. This only
- applies when the playback sample format is f32.
-
- dataCallback
- The callback to fire whenever data is ready to be delivered to or from the device.
-
- stopCallback
- The callback to fire whenever the device has stopped, either explicitly via `ma_device_stop()`, or implicitly due to things like the device being
- disconnected.
-
- pUserData
- The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`.
-
- resampling.algorithm
- The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The
- default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`.
-
- resampling.linear.lpfOrder
- The linear resampler applies a low-pass filter as part of it's procesing for anti-aliasing. This setting controls the order of the filter. The higher
- the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is
- `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`.
-
- playback.pDeviceID
- A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's
- default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
-
- playback.format
- The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
- initialization from the device object directly with `device.playback.format`.
-
- playback.channels
- The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
- from the device object directly with `device.playback.channels`.
-
- playback.channelMap
- The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
- device object direct with `device.playback.channelMap`.
-
- playback.shareMode
- The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
- exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
- ma_share_mode_shared and reinitializing.
-
- capture.pDeviceID
- A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize. Setting this NULL (default) will use the system's
- default capture device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
-
- capture.format
- The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
- initialization from the device object directly with `device.capture.format`.
-
- capture.channels
- The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
- from the device object directly with `device.capture.channels`.
-
- capture.channelMap
- The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
- device object direct with `device.capture.channelMap`.
-
- capture.shareMode
- The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
- exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
- ma_share_mode_shared and reinitializing.
-
- wasapi.noAutoConvertSRC
- WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false.
-
- wasapi.noDefaultQualitySRC
- WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`.
- You should usually leave this set to false, which is the default.
-
- wasapi.noAutoStreamRouting
- WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false.
-
- wasapi.noHardwareOffloading
- WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false.
-
- alsa.noMMap
- ALSA only. When set to true, disables MMap mode. Defaults to false.
-
- alsa.noAutoFormat
- ALSA only. When set to true, disables ALSA's automatic format conversion by including the SND_PCM_NO_AUTO_FORMAT flag. Defaults to false.
-
- alsa.noAutoChannels
- ALSA only. When set to true, disables ALSA's automatic channel conversion by including the SND_PCM_NO_AUTO_CHANNELS flag. Defaults to false.
-
- alsa.noAutoResample
- ALSA only. When set to true, disables ALSA's automatic resampling by including the SND_PCM_NO_AUTO_RESAMPLE flag. Defaults to false.
-
- pulse.pStreamNamePlayback
- PulseAudio only. Sets the stream name for playback.
-
- pulse.pStreamNameCapture
- PulseAudio only. Sets the stream name for capture.
-
- coreaudio.allowNominalSampleRateChange
- Core Audio only. Desktop only. When enabled, allows the sample rate of the device to be changed at the operating system level. This
- is disabled by default in order to prevent intrusive changes to the user's system. This is useful if you want to use a sample rate
- that is known to be natively supported by the hardware thereby avoiding the cost of resampling. When set to true, miniaudio will
- find the closest match between the sample rate requested in the device config and the sample rates natively supported by the
- hardware. When set to false, the sample rate currently set by the operating system will always be used.
-
-
-Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device.
-
-After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`.
-
-If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or
-`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or
-`ma_performance_profile_conservative`.
-
-If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device
-in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the
-config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA,
-for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user.
-Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary.
-
-When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config
-and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run
-on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`,
-`playback/capture.channels` and `sampleRate` members of the device object.
-
-When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message
-asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information.
-
-ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture.
-If these fail it will try falling back to the "hw" device.
-
-
-Example 1 - Simple Initialization
----------------------------------
-This example shows how to initialize a simple playback device using a standard configuration. If you are just needing to do simple playback from the default
-playback device this is usually all you need.
-
-```c
-ma_device_config config = ma_device_config_init(ma_device_type_playback);
-config.playback.format = ma_format_f32;
-config.playback.channels = 2;
-config.sampleRate = 48000;
-config.dataCallback = ma_data_callback;
-config.pMyUserData = pMyUserData;
-
-ma_device device;
-ma_result result = ma_device_init(NULL, &config, &device);
-if (result != MA_SUCCESS) {
- // Error
-}
-```
-
-
-Example 2 - Advanced Initialization
------------------------------------
-This example shows how you might do some more advanced initialization. In this hypothetical example we want to control the latency by setting the buffer size
-and period count. We also want to allow the user to be able to choose which device to output from which means we need a context so we can perform device
-enumeration.
-
-```c
-ma_context context;
-ma_result result = ma_context_init(NULL, 0, NULL, &context);
-if (result != MA_SUCCESS) {
- // Error
-}
-
-ma_device_info* pPlaybackDeviceInfos;
-ma_uint32 playbackDeviceCount;
-result = ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, NULL, NULL);
-if (result != MA_SUCCESS) {
- // Error
-}
-
-// ... choose a device from pPlaybackDeviceInfos ...
-
-ma_device_config config = ma_device_config_init(ma_device_type_playback);
-config.playback.pDeviceID = pMyChosenDeviceID; // <-- Get this from the `id` member of one of the `ma_device_info` objects returned by ma_context_get_devices().

-`pDescriptor` object. Since buffer size calculations based on time depends on the sample rate, a

- The device's native sample rate. This is only ever used when the `periodSizeInFrames` member of

--------
-If you want to retrieve the number of backends so you can determine the capacity of `pBackends` buffer, you can call

-
-This will also enumerate the null backend. If you don't want to include this you need to check for `ma_backend_null`
-when you enumerate over the returned backends and handle it appropriately. Alternatively, you can disable it at
-compile time with `MA_NO_NULL`.
-
-The returned backends are determined based on compile time settings, not the platform it's currently running on. For

- We could define ma_device_uninit() such that it must be called on the same thread as

- resampling.
-
- To reproduce this problem, open the "plug:dmix" device, and set the sample rate to 44100. Internally, it looks like dmix uses a
- sample rate of 48000. The hardware parameters will get set correctly with no errors, but it looks like the 44100 -> 48000 resampling
- doesn't work properly - but only with MMAP access mode. You will notice skipping/crackling in the audio, and it'll run at a slightly
- faster rate.
-
- miniaudio has built-in support for sample rate conversion (albeit low quality at the moment), so disabling resampling should be fine
- for us. The only problem is that it won't be taking advantage of any kind of hardware-accelerated resampling and it won't be very
- good quality until I get a chance to improve the quality of miniaudio's software sample rate conversion.
-
- I don't currently know if the dmix plugin is the only one with this error. Indeed, this is the only one I've been able to reproduce
- this error with. In the future, we may want to restrict the disabling of resampling to only known bad plugins.

-PulseAudio Backend
-
-******************************************************************************/
-#ifdef MA_HAS_PULSEAUDIO
-/*
-The PulseAudio API, along with Apple's Core Audio, is the worst of the maintream audio APIs. This is a brief description of what's going on
-in the PulseAudio backend. I apologize if this gets a bit ranty for your liking - you might want to skip this discussion.
-
-PulseAudio has something they call the "Simple API", which unfortunately isn't suitable for miniaudio. I've not seen anywhere where it
-allows you to enumerate over devices, nor does it seem to support the ability to stop and start streams. Looking at the documentation, it
-appears as though the stream is constantly running and you prevent sound from being emitted or captured by simply not calling the read or
-write functions. This is not a professional solution as it would be much better to *actually* stop the underlying stream. Perhaps the
-simple API has some smarts to do this automatically, but I'm not sure. Another limitation with the simple API is that it seems inefficient
-when you want to have multiple streams to a single context. For these reasons, miniaudio is not using the simple API.
-
-Since we're not using the simple API, we're left with the asynchronous API as our only other option. And boy, is this where it starts to
-get fun, and I don't mean that in a good way...
-
-The problems start with the very name of the API - "asynchronous". Yes, this is an asynchronous oriented API which means your commands
-don't immediately take effect. You instead need to issue your commands, and then wait for them to complete. The waiting mechanism is
-enabled through the use of a "main loop". In the asychronous API you cannot get away from the main loop, and the main loop is where almost
-all of PulseAudio's problems stem from.
-
-When you first initialize PulseAudio you need an object referred to as "main loop". You can implement this yourself by defining your own
-vtable, but it's much easier to just use one of the built-in main loop implementations. There's two generic implementations called
-pa_mainloop and pa_threaded_mainloop, and another implementation specific to GLib called pa_glib_mainloop. We're using pa_threaded_mainloop
-because it simplifies management of the worker thread. The idea of the main loop object is pretty self explanatory - you're supposed to use
-it to implement a worker thread which runs in a loop. The main loop is where operations are actually executed.
-
-To initialize the main loop, you just use `pa_threaded_mainloop_new()`. This is the first function you'll call. You can then get a pointer
-to the vtable with `pa_threaded_mainloop_get_api()` (the main loop vtable is called `pa_mainloop_api`). Again, you can bypass the threaded
-main loop object entirely and just implement `pa_mainloop_api` directly, but there's no need for it unless you're doing something extremely
-specialized such as if you want to integrate it into your application's existing main loop infrastructure.
-
-(EDIT 2021-01-26: miniaudio is no longer using `pa_threaded_mainloop` due to this issue: https://github.com/mackron/miniaudio/issues/262.
-It is now using `pa_mainloop` which turns out to be a simpler solution anyway. The rest of this rant still applies, however.)
-
-Once you have your main loop vtable (the `pa_mainloop_api` object) you can create the PulseAudio context. This is very similar to
-miniaudio's context and they map to each other quite well. You have one context to many streams, which is basically the same as miniaudio's
-one `ma_context` to many `ma_device`s. Here's where it starts to get annoying, however. When you first create the PulseAudio context, which
-is done with `pa_context_new()`, it's not actually connected to anything. When you connect, you call `pa_context_connect()`. However, if
-you remember, PulseAudio is an asynchronous API. That means you cannot just assume the context is connected after `pa_context_context()`
-has returned. You instead need to wait for it to connect. To do this, you need to either wait for a callback to get fired, which you can
-set with `pa_context_set_state_callback()`, or you can continuously poll the context's state. Either way, you need to run this in a loop.
-All objects from here out are created from the context, and, I believe, you can't be creating these objects until the context is connected.
-This waiting loop is therefore unavoidable. In order for the waiting to ever complete, however, the main loop needs to be running. Before
-attempting to connect the context, the main loop needs to be started with `pa_threaded_mainloop_start()`.
-
-The reason for this asynchronous design is to support cases where you're connecting to a remote server, say through a local network or an
-internet connection. However, the *VAST* majority of cases don't involve this at all - they just connect to a local "server" running on the
-host machine. The fact that this would be the default rather than making `pa_context_connect()` synchronous tends to boggle the mind.
-
-Once the context has been created and connected you can start creating a stream. A PulseAudio stream is analogous to miniaudio's device.
-The initialization of a stream is fairly standard - you configure some attributes (analogous to miniaudio's device config) and then call
-`pa_stream_new()` to actually create it. Here is where we start to get into "operations". When configuring the stream, you can get
-information about the source (such as sample format, sample rate, etc.), however it's not synchronous. Instead, a `pa_operation` object
-is returned from `pa_context_get_source_info_by_name()` (capture) or `pa_context_get_sink_info_by_name()` (playback). Then, you need to
-run a loop (again!) to wait for the operation to complete which you can determine via a callback or polling, just like we did with the
-context. Then, as an added bonus, you need to decrement the reference counter of the `pa_operation` object to ensure memory is cleaned up.
-All of that just to retrieve basic information about a device!
-
-Once the basic information about the device has been retrieved, miniaudio can now create the stream with `ma_stream_new()`. Like the
-context, this needs to be connected. But we need to be careful here, because we're now about to introduce one of the most horrific design
-choices in PulseAudio.
-
-PulseAudio allows you to specify a callback that is fired when data can be written to or read from a stream. The language is important here
-because PulseAudio takes it literally, specifically the "can be". You would think these callbacks would be appropriate as the place for
-writing and reading data to and from the stream, and that would be right, except when it's not. When you initialize the stream, you can
-set a flag that tells PulseAudio to not start the stream automatically. This is required because miniaudio does not auto-start devices
-straight after initialization - you need to call `ma_device_start()` manually. The problem is that even when this flag is specified,
-PulseAudio will immediately fire it's write or read callback. This is *technically* correct (based on the wording in the documentation)
-because indeed, data *can* be written at this point. The problem is that it's not *practical*. It makes sense that the write/read callback
-would be where a program will want to write or read data to or from the stream, but when it's called before the application has even
-requested that the stream be started, it's just not practical because the program probably isn't ready for any kind of data delivery at
-that point (it may still need to load files or whatnot). Instead, this callback should only be fired when the application requests the
-stream be started which is how it works with literally *every* other callback-based audio API. Since miniaudio forbids firing of the data
-callback until the device has been started (as it should be with *all* callback based APIs), logic needs to be added to ensure miniaudio
-doesn't just blindly fire the application-defined data callback from within the PulseAudio callback before the stream has actually been
-started. The device state is used for this - if the state is anything other than `MA_STATE_STARTING` or `MA_STATE_STARTED`, the main data
-callback is not fired.
-
-This, unfortunately, is not the end of the problems with the PulseAudio write callback. Any normal callback based audio API will
-continuously fire the callback at regular intervals based on the size of the internal buffer. This will only ever be fired when the device
-is running, and will be fired regardless of whether or not the user actually wrote anything to the device/stream. This not the case in
-PulseAudio. In PulseAudio, the data callback will *only* be called if you wrote something to it previously. That means, if you don't call
-`pa_stream_write()`, the callback will not get fired. On the surface you wouldn't think this would matter because you should be always
-writing data, and if you don't have anything to write, just write silence. That's fine until you want to drain the stream. You see, if
-you're continuously writing data to the stream, the stream will never get drained! That means in order to drain the stream, you need to
-*not* write data to it! But remember, when you don't write data to the stream, the callback won't get fired again! Why is draining
-important? Because that's how we've defined stopping to work in miniaudio. In miniaudio, stopping the device requires it to be drained
-before returning from ma_device_stop(). So we've stopped the device, which requires us to drain, but draining requires us to *not* write
-data to the stream (or else it won't ever complete draining), but not writing to the stream means the callback won't get fired again!
-
-This becomes a problem when stopping and then restarting the device. When the device is stopped, it's drained, which requires us to *not*
-write anything to the stream. But then, since we didn't write anything to it, the write callback will *never* get called again if we just
-resume the stream naively. This means that starting the stream requires us to write data to the stream from outside the callback. This
-disconnect is something PulseAudio has got seriously wrong - there should only ever be a single source of data delivery, that being the
-callback. (I have tried using `pa_stream_flush()` to trigger the write callback to fire, but this just doesn't work for some reason.)
-
-Once you've created the stream, you need to connect it which involves the whole waiting procedure. This is the same process as the context,
-only this time you'll poll for the state with `pa_stream_get_status()`. The starting and stopping of a streaming is referred to as
-"corking" in PulseAudio. The analogy is corking a barrel. To start the stream, you uncork it, to stop it you cork it. Personally I think
-it's silly - why would you not just call it "starting" and "stopping" like any other normal audio API? Anyway, the act of corking is, you
-guessed it, asynchronous. This means you'll need our waiting loop as usual. Again, why this asynchronous design is the default is
-absolutely beyond me. Would it really be that hard to just make it run synchronously?
-
-Teardown is pretty simple (what?!). It's just a matter of calling the relevant `_unref()` function on each object in reverse order that
-they were initialized in.
-
-That's about it from the PulseAudio side. A bit ranty, I know, but they really need to fix that main loop and callback system. They're
-embarrassingly unpractical. The main loop thing is an easy fix - have synchronous versions of all APIs. If an application wants these to
-run asynchronously, they can execute them in a separate thread themselves. The desire to run these asynchronously is such a niche
-requirement - it makes no sense to make it the default. The stream write callback needs to be change, or an alternative provided, that is
-constantly fired, regardless of whether or not `pa_stream_write()` has been called, and it needs to take a pointer to a buffer as a
-parameter which the program just writes to directly rather than having to call `pa_stream_writable_size()` and `pa_stream_write()`. These
-changes alone will change PulseAudio from one of the worst audio APIs to one of the best.

-Core Audio
-
-So far, Core Audio has been the worst backend to work with due to being both unintuitive and having almost no documentation
-apart from comments in the headers (which admittedly are quite good). For my own purposes, and for anybody out there whose
-needing to figure out how this darn thing works, I'm going to outline a few things here.
-
-Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be
-able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen
-that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent
-and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the
-distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API.
-
-Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When
-retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific
-data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the
-devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be
-the central APIs for retrieving information about the system and specific devices.
-
-To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a
-structure with three variables and is used to identify which property you are getting or setting. The first is the "selector"
-which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is
-typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and
-kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to
-kAudioObjectPropertyElementMaster in miniaudio's case. I don't know of any cases where this would be set to anything different.
-
-Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size
-of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property
-address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the
-size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of
-AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count.

- Technical Note TN2091: Device input using the HAL Output Audio Unit
- https://developer.apple.com/library/archive/technotes/tn2091/_index.html
-
- This documentation says the following:
-
- The internal AudioConverter can handle any *simple* conversion. Typically, this means that a client can specify ANY
- variant of the PCM formats. Consequently, the device's sample rate should match the desired sample rate. If sample rate
- conversion is needed, it can be accomplished by buffering the input and converting the data on a separate thread with
- another AudioConverter.
-
- The important part here is the mention that it can handle *simple* conversions, which does *not* include sample rate. We
- therefore want to ensure the sample rate stays consistent. This document is specifically for input, but I'm going to play it
- safe and apply the same rule to output as well.
-
- I have tried going against the documentation by setting the sample rate anyway, but this just results in AudioUnitRender()
- returning a result code of -10863. I have also tried changing the format directly on the input scope on the input bus, but
- this just results in `ca_require: IsStreamFormatWritable(inScope, inElement) NotWritable` when trying to set the format.
-
- Something that does seem to work, however, has been setting the nominal sample rate on the deivce object. The problem with
- this, however, is that it actually changes the sample rate at the operating system level and not just the application. This
- could be intrusive to the user, however, so I don't think it's wise to make this the default. Instead I'm making this a
- configuration option. When the `coreaudio.allowNominalSampleRateChange` config option is set to true, changing the sample
- rate will be allowed. Otherwise it'll be fixed to the current sample rate. To check the system-defined sample rate, run
- the Audio MIDI Setup program that comes installed on macOS and observe how the sample rate changes as the sample rate is
- changed by miniaudio.

-Note on Starting and Stopping
-=============================
-In the past I was using SNDCTL_DSP_HALT to stop the device, however this results in issues when
-trying to resume the device again. If we use SNDCTL_DSP_HALT, the next write() or read() will
-fail. Instead what we need to do is just not write or read to and from the device when the
-device is not running.
-
-As a result, both the start and stop functions for OSS are just empty stubs. The starting and
-stopping logic is handled by ma_device_write__oss() and ma_device_read__oss(). These will check
-the device state, and if the device is stopped they will simply not do any kind of processing.
-
-The downside to this technique is that I've noticed a fairly lengthy delay in stopping the
-device, up to a second. This is on a virtual machine, and as such might just be due to the
-virtual drivers, but I'm not fully sure. I am not sure how to work around this problem so for
-the moment that's just how it's going to have to be.
-
-When starting the device, OSS will automatically start it when write() or read() is called.

- ScriptProcessorNode is actually deprecated so this is likely to be temporary. The way this works for playback is very simple. You just set a callback

- something called AudioWorklets which _forces_ you to load a _separate_ .js file at run time... nice... Hopefully ScriptProcessorNode will continue to
- work for years to come, but this may need to change to use AudioSourceBufferNode instead, which I think is what Emscripten uses for it's built-in SDL
- implementation. I'll be avoiding that insane AudioWorklet API like the plague...
-
- For capture it is a bit unintuitive. We use the ScriptProccessorNode _only_ to get the raw PCM data. It is connected to an AudioContext just like the
- playback case, however we just output silence to the AudioContext instead of passing any real data. It would make more sense to me to use the
- MediaRecorder API, but unfortunately you need to specify a MIME time (Opus, Vorbis, etc.) for the binary blob that's returned to the client, but I've
- been unable to figure out how to get this as raw PCM. The closest I can think is to use the MIME type for WAV files and just parse it, but I don't know
- how well this would work. Although ScriptProccessorNode is deprecated, in practice it seems to have pretty good browser support so I'm leaving it like
- this for now. If anyone knows how I could get raw PCM data using the MediaRecorder API please let me know!

- Imagine the following simplified example: You have a single input speaker which is the front/left speaker which you want to convert to
- the following output configuration:
-
- - front/left
- - side/left
- - back/left
-
- The front/left output is easy - it the same speaker position so it receives the full contribution of the front/left input. The amount
- of contribution to apply to the side/left and back/left speakers, however, is a bit more complicated.
-
- Imagine the front/left speaker as emitting audio from two planes - the front plane and the left plane. You can think of the front/left
- speaker emitting half of it's total volume from the front, and the other half from the left. Since part of it's volume is being emitted
- from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would
- receive some amount of contribution from front/left speaker. The amount of contribution depends on how many planes are shared between
- the two speakers. Note that in the examples below I've added a top/front/left speaker as an example just to show how the math works
- across 3 spatial dimensions.
-
- The first thing to do is figure out how each speaker's volume is spread over each of plane:
- - front/left: 2 planes (front and left) = 1/2 = half it's total volume on each plane
- - side/left: 1 plane (left only) = 1/1 = entire volume from left plane
- - back/left: 2 planes (back and left) = 1/2 = half it's total volume on each plane
- - top/front/left: 3 planes (top, front and left) = 1/3 = one third it's total volume on each plane
-
- The amount of volume each channel contributes to each of it's planes is what controls how much it is willing to given and take to other
- channels on the same plane. The volume that is willing to the given by one channel is multiplied by the volume that is willing to be
- taken by the other to produce the final contribution.

-RELEASE NOTES - VERSION 0.10.x
-==============================
-Version 0.10 includes major API changes and refactoring, mostly concerned with the data conversion system. Data conversion is performed internally to convert
-audio data between the format requested when initializing the `ma_device` object and the format of the internal device used by the backend. The same applies
-to the `ma_decoder` object. The previous design has several design flaws and missing features which necessitated a complete redesign.
-
-
-Changes to Data Conversion
---------------------------
-The previous data conversion system used callbacks to deliver input data for conversion. This design works well in some specific situations, but in other
-situations it has some major readability and maintenance issues. The decision was made to replace this with a more iterative approach where you just pass in a
-pointer to the input data directly rather than dealing with a callback.
-
-The following are the data conversion APIs that have been removed and their replacements:
-
- - ma_format_converter -> ma_convert_pcm_frames_format()
- - ma_channel_router -> ma_channel_converter
- - ma_src -> ma_resampler
- - ma_pcm_converter -> ma_data_converter
-
-The previous conversion APIs accepted a callback in their configs. There are no longer any callbacks to deal with. Instead you just pass the data into the
-`*_process_pcm_frames()` function as a pointer to a buffer.
-
-The simplest aspect of data conversion is sample format conversion. To convert between two formats, just call `ma_convert_pcm_frames_format()`. Channel
-conversion is also simple which you can do with `ma_channel_converter` via `ma_channel_converter_process_pcm_frames()`.
-
-Resampling is more complicated because the number of output frames that are processed is different to the number of input frames that are consumed. When you
-call `ma_resampler_process_pcm_frames()` you need to pass in the number of input frames available for processing and the number of output frames you want to
-output. Upon returning they will receive the number of input frames that were consumed and the number of output frames that were generated.
-
-The `ma_data_converter` API is a wrapper around format, channel and sample rate conversion and handles all of the data conversion you'll need which probably
-makes it the best option if you need to do data conversion.
-
-In addition to changes to the API design, a few other changes have been made to the data conversion pipeline:
-
- - The sinc resampler has been removed. This was completely broken and never actually worked properly.
- - The linear resampler now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with the
- `lpfOrder` option, which has a maximum value of MA_MAX_FILTER_ORDER.
- - Data conversion now supports s16 natively which runs through a fixed point pipeline. Previously everything needed to be converted to floating point before
- processing, whereas now both s16 and f32 are natively supported. Other formats still require conversion to either s16 or f32 prior to processing, however
- `ma_data_converter` will handle this for you.
-
-
-Custom Memory Allocators
-------------------------
-miniaudio has always supported macro level customization for memory allocation via MA_MALLOC, MA_REALLOC and MA_FREE, however some scenarios require more
-flexibility by allowing a user data pointer to be passed to the custom allocation routines. Support for this has been added to version 0.10 via the
-`ma_allocation_callbacks` structure. Anything making use of heap allocations has been updated to accept this new structure.
-
-The `ma_context_config` structure has been updated with a new member called `allocationCallbacks`. Leaving this set to it's defaults returned by
-`ma_context_config_init()` will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. Likewise, The `ma_decoder_config` structure has been updated in the same
-way, and leaving everything as-is after `ma_decoder_config_init()` will cause it to use the same defaults.
-
-The following APIs have been updated to take a pointer to a `ma_allocation_callbacks` object. Setting this parameter to NULL will cause it to use defaults.
-Otherwise they will use the relevant callback in the structure.
-
- - ma_malloc()
- - ma_realloc()
- - ma_free()
- - ma_aligned_malloc()
- - ma_aligned_free()
- - ma_rb_init() / ma_rb_init_ex()
- - ma_pcm_rb_init() / ma_pcm_rb_init_ex()
-
-Note that you can continue to use MA_MALLOC, MA_REALLOC and MA_FREE as per normal. These will continue to be used by default if you do not specify custom
-allocation callbacks.
-
-
-Buffer and Period Configuration Changes
----------------------------------------
-The way in which the size of the internal buffer and periods are specified in the device configuration have changed. In previous versions, the config variables
-`bufferSizeInFrames` and `bufferSizeInMilliseconds` defined the size of the entire buffer, with the size of a period being the size of this variable divided by
-the period count. This became confusing because people would expect the value of `bufferSizeInFrames` or `bufferSizeInMilliseconds` to independantly determine
-latency, when in fact it was that value divided by the period count that determined it. These variables have been removed and replaced with new ones called
-`periodSizeInFrames` and `periodSizeInMilliseconds`.
-
-These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is
-that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to
-configure latency.
-
-The following unused APIs have been removed:
-
- ma_get_default_buffer_size_in_milliseconds()
- ma_get_default_buffer_size_in_frames()
-
-The following macros have been removed:
-
- MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY
- MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE
-
-
-Other API Changes
------------------
-Other less major API changes have also been made in version 0.10.
-
-`ma_device_set_stop_callback()` has been removed. If you require a stop callback, you must now set it via the device config just like the data callback.
-
-The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including
-sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes a configuration
-object called `ma_waveform_config` which defines the properties of the waveform. Use `ma_waveform_config_init()` to initialize a `ma_waveform_config` object.
-Use `ma_waveform_read_pcm_frames()` in place of `ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`.
-
-`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies
-the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to
-take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it more flexible, to
-prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added.
-
-`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API.
-
-
-Filters
--------
-The following filters have been added:
-
- |-------------|-------------------------------------------------------------------|
- | API | Description |
- |-------------|-------------------------------------------------------------------|
- | ma_biquad | Biquad filter (transposed direct form 2) |
- | ma_lpf1 | First order low-pass filter |
- | ma_lpf2 | Second order low-pass filter |
- | ma_lpf | High order low-pass filter (Butterworth) |
- | ma_hpf1 | First order high-pass filter |
- | ma_hpf2 | Second order high-pass filter |
- | ma_hpf | High order high-pass filter (Butterworth) |
- | ma_bpf2 | Second order band-pass filter |
- | ma_bpf | High order band-pass filter |
- | ma_peak2 | Second order peaking filter |
- | ma_notch2 | Second order notching filter |
- | ma_loshelf2 | Second order low shelf filter |
- | ma_hishelf2 | Second order high shelf filter |
- |-------------|-------------------------------------------------------------------|
-
-These filters all support 32-bit floating point and 16-bit signed integer formats natively. Other formats need to be converted beforehand.
-
-
-Sine, Square, Triangle and Sawtooth Waveforms
----------------------------------------------
-Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old
-`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_config_init()` to initialize a config object, and then pass it
-into `ma_waveform_init()`. Then use `ma_waveform_read_pcm_frames()` to read PCM data.
-
-
-Noise Generation
-----------------
-A noise generation API has been added. This is used via the `ma_noise` API. Currently white, pink and Brownian noise is supported. The `ma_noise` API is
-similar to the waveform API. Use `ma_noise_config_init()` to initialize a config object, and then pass it into `ma_noise_init()` to initialize a `ma_noise`
-object. Then use `ma_noise_read_pcm_frames()` to read PCM data.
-
-
-Miscellaneous Changes
----------------------
-The MA_NO_STDIO option has been removed. This would disable file I/O APIs, however this has proven to be too hard to maintain for it's perceived value and was
-therefore removed.
-
-Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report.
-
-The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on
-the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it
-was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work,
-this has been removed from all structures.
-
-Results codes have been overhauled. Unnecessary result codes have been removed, and some have been renumbered for organisation purposes. If you are are binding
-maintainer you will need to update your result codes. Support has also been added for retrieving a human readable description of a given result code via the
-`ma_result_description()` API.
-
-ALSA: The automatic format conversion, channel conversion and resampling performed by ALSA is now disabled by default as they were causing some compatibility
-issues with certain devices and configurations. These can be individually enabled via the device config:
-
- ```c
- deviceConfig.alsa.noAutoFormat = MA_TRUE;
- deviceConfig.alsa.noAutoChannels = MA_TRUE;
- deviceConfig.alsa.noAutoResample = MA_TRUE;
- ```

-RELEASE NOTES - VERSION 0.9.x
-=============================
-Version 0.9 includes major API changes, centered mostly around full-duplex and the rebrand to "miniaudio". Before I go into detail about the major changes I
-would like to apologize. I know it's annoying dealing with breaking API changes, but I think it's best to get these changes out of the way now while the
-library is still relatively young and unknown.
-
-There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in advance for this. You may want to
-hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for you, and you don't need full-duplex support, you can avoid upgrading
-(though you won't be getting future bug fixes).
-
-
-Rebranding to "miniaudio"
--------------------------
-The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple:
-
-1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and
-2) I don't like the look of the underscore.
-
-This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's better to get this out of the road
-now rather than later. Also, since there are necessary API changes for full-duplex support I think it's better to just get the namespace change over and done
-with at the same time as the full-duplex changes. I'm hoping this will be the last of the major API changes. Fingers crossed!
-
-The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's your preference.
-
-
-Full-Duplex Support
--------------------
-The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes.
-
-1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted to avoid a third callback just
- for full-duplex so the decision was made to break this API and unify the callbacks. Now, there is just one callback which is the same for all three modes
- (playback, capture, duplex). The new callback looks like the following:
-
- void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
-
- This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In playback-only mode, pInput will be
- null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer returned from the callback since it's not necessary for miniaudio
- anymore.
-
-2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client to choose a different PCM format
- for the playback and capture sides. The old ma_device_config object simply did not allow this and needed to change. With these changes you now specify the
- device ID, format, channels, channel map and share mode on a per-playback and per-capture basis (see example below). The sample rate must be the same for
- playback and capture.
-
- Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now, the device ID, device type and
- callback user data are set in the config. ma_device_init() is now simplified down to taking just the context, device config and a pointer to the device
- object being initialized. The rationale for this change is that it just makes more sense to me that these are set as part of the config like everything
- else.
-
- Example device initialization:
-
- ma_device_config config = ma_device_config_init(ma_device_type_duplex); // Or ma_device_type_playback or ma_device_type_capture.
- config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device.
- config.playback.format = ma_format_f32;
- config.playback.channels = 2;
- config.capture.pDeviceID = &myCaptureDeviceID; // Or NULL for the default capture device.
- config.capture.format = ma_format_s16;
- config.capture.channels = 1;
- config.sampleRate = 44100;
- config.dataCallback = data_callback;
- config.pUserData = &myUserData;
-
- result = ma_device_init(&myContext, &config, &device);
- if (result != MA_SUCCESS) {
- ... handle error ...
- }
-
- Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has been renamed to "stopCallback".
-
-This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample rate conversion is required for
-the playback device:
- - Core Audio
- - JACK
- - AAudio
- - OpenSL
- - WebAudio
-
-In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such thorough testing. If you
-experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample program that reproduces the issue if possible).
-
-
-Other API Changes
------------------
-In addition to the above, the following API changes have been made:
-
-- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization.
-- The onLogCallback member of ma_context_config has been renamed to "logCallback".
-- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
- - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it.
-- Some APIs have been renamed:
- - mal_decoder_read() -> ma_decoder_read_pcm_frames()
- - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
- - mal_sine_wave_read() -> ma_sine_wave_read_f32()
- - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
-- Some APIs have been removed:
- - mal_device_get_buffer_size_in_bytes()
- - mal_device_set_recv_callback()
- - mal_device_set_send_callback()
- - mal_src_set_input_sample_rate()
- - mal_src_set_output_sample_rate()
-- Error codes have been rearranged. If you're a binding maintainer you will need to update.
-- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection and to make it easier to see
- the priority. If you're a binding maintainer you will need to update.
-- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with some future planned high-level
- APIs.
-- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that the pointer comes before the
- count. The rationale for this is to keep it consistent with things like memcpy().
-
-
-Miscellaneous Changes
----------------------
-The following miscellaneous changes have also been made.
-
-- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the record, this is one of the nicest
- audio APIs out there, just behind the BSD audio APIs).
-- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL.
-- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio was not explicitly
- supported. These are no longer needed and have therefore been removed.
-- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an exclusive mode device, or an
- error. The rationale for this change is to give the client more control over how to handle cases when the desired shared mode is unavailable.
-- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb" operates on PCM frames.
-- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but removes the attribution
- requirement. The rationale for this is to support countries that don't recognize public domain.

-
-v0.10.9 - 2020-06-24
- - Amalgamation of dr_wav, dr_flac and dr_mp3. With this change, including the header section of these libraries before the implementation of miniaudio is no
- longer required. Decoding of WAV, FLAC and MP3 should be supported seamlessly without any additional libraries. Decoders can be excluded from the build
- with the following options:
- - MA_NO_WAV
- - MA_NO_FLAC
- - MA_NO_MP3
- If you get errors about multiple definitions you need to either enable the options above, move the implementation of dr_wav, dr_flac and/or dr_mp3 to before

- - Change playback.pDeviceID and capture.pDeviceID to constant pointers in ma_device_config.
- - Add support for initializing decoders from a virtual file system object. This is achieved via the ma_vfs API and allows the application to customize file
- IO for the loading and reading of raw audio data. Passing in NULL for the VFS will use defaults. New APIs:
- - ma_decoder_init_vfs()
- - ma_decoder_init_vfs_wav()
- - ma_decoder_init_vfs_flac()

- - ma_get_default_buffer_size_in_milliseconds()
- - ma_get_default_buffer_size_in_frames()
- - API CHANGE: ma_device_set_stop_callback() has been removed. If you require a stop callback, you must now set it via the device config just like the data

- - Core Audio: Fix bugs with automatic stream routing.
- - Add support for controlling whether or not the content of the output buffer passed in to the data callback is pre-initialized
- to zero. By default it will be initialized to zero, but this can be changed by setting noPreZeroedOutputBuffer in the device
- config. Setting noPreZeroedOutputBuffer to true will leave the contents undefined.
- - Add support for clipping samples after the data callback has returned. This only applies when the playback sample format is
- configured as ma_format_f32. If you are doing clipping yourself, you can disable this overhead by setting noClip to true in
- the device config.
- - Add support for master volume control for devices.
- - Use ma_device_set_master_volume() to set the volume to a factor between 0 and 1, where 0 is silence and 1 is full volume.

- Microsoft compilers back to VC6. Other compilers should also work, but have not been tested.
-
-v0.9.3 - 2019-04-19

- - Fix an issue where the data callback is getting called too frequently on the WASAPI and DirectSound backends.
- - Fix error on the UWP build.
- - Fix a build error on Apple platforms.
-
-v0.9 - 2019-03-06
- - Rebranded to "miniaudio". All namespaces have been renamed from "mal" to "ma".
- - API CHANGE: ma_device_init() and ma_device_config_init() have changed significantly:
- - The device type, device ID and user data pointer have moved from ma_device_init() to the config.
- - All variations of ma_device_config_init_*() have been removed in favor of just ma_device_config_init().
- - ma_device_config_init() now takes only one parameter which is the device type. All other properties need
- to be set on the returned object directly.
- - The onDataCallback and onStopCallback members of ma_device_config have been renamed to "dataCallback"
- and "stopCallback".
- - The ID of the physical device is now split into two: one for the playback device and the other for the
- capture device. This is required for full-duplex. These are named "pPlaybackDeviceID" and "pCaptureDeviceID".
- - API CHANGE: The data callback has changed. It now uses a unified callback for all device types rather than
- being separate for each. It now takes two pointers - one containing input data and the other output data. This
- design in required for full-duplex. The return value is now void instead of the number of frames written. The
- new callback looks like the following:
- void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
- - API CHANGE: Remove the log callback parameter from ma_context_config_init(). With this change,
- ma_context_config_init() now takes no parameters and the log callback is set via the structure directly. The
- new policy for config initialization is that only mandatory settings are passed in to *_config_init(). The
- "onLog" member of ma_context_config has been renamed to "logCallback".
- - API CHANGE: Remove ma_device_get_buffer_size_in_bytes().
- - API CHANGE: Rename decoding APIs to "pcm_frames" convention.
- - mal_decoder_read() -> ma_decoder_read_pcm_frames()
- - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
- - API CHANGE: Rename sine wave reading APIs to f32 convention.
- - mal_sine_wave_read() -> ma_sine_wave_read_f32()
- - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
- - API CHANGE: Remove some deprecated APIs
- - mal_device_set_recv_callback()
- - mal_device_set_send_callback()
- - mal_src_set_input_sample_rate()
- - mal_src_set_output_sample_rate()
- - API CHANGE: Add log level to the log callback. New signature:
- - void on_log(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
- - API CHANGE: Changes to result codes. Constants have changed and unused codes have been removed. If you're
- a binding mainainer you will need to update your result code constants.
- - API CHANGE: Change the order of the ma_backend enums to priority order. If you are a binding maintainer, you
- will need to update.
- - API CHANGE: Rename mal_dsp to ma_pcm_converter. All functions have been renamed from mal_dsp_*() to
- ma_pcm_converter_*(). All structures have been renamed from mal_dsp* to ma_pcm_converter*.
- - API CHANGE: Reorder parameters of ma_decoder_read_pcm_frames() to be consistent with the new parameter order scheme.
- - The resampling algorithm has been changed from sinc to linear. The rationale for this is that the sinc implementation
- is too inefficient right now. This will hopefully be improved at a later date.
- - Device initialization will no longer fall back to shared mode if exclusive mode is requested but is unusable.
- With this change, if you request an device in exclusive mode, but exclusive mode is not supported, it will not
- automatically fall back to shared mode. The client will need to reinitialize the device in shared mode if that's
- what they want.
- - Add ring buffer API. This is ma_rb and ma_pcm_rb, the difference being that ma_rb operates on bytes and
- ma_pcm_rb operates on PCM frames.
- - Add Web Audio backend. This is used when compiling with Emscripten. The SDL backend, which was previously
- used for web support, will be removed in a future version.
- - Add AAudio backend (Android Audio). This is the new priority backend for Android. Support for AAudio starts
- with Android 8. OpenSL|ES is used as a fallback for older versions of Android.
- - Remove OpenAL and SDL backends.
- - Fix a possible deadlock when rapidly stopping the device after it has started.
- - Update documentation.
- - Change licensing to a choice of public domain _or_ MIT-0 (No Attribution).

- - Fix a bug with UWP detection.
-
-v0.8.6 - 2018-08-26
- - Automatically switch the internal device when the default device is unplugged. Note that this is still in the
- early stages and not all backends handle this the same way. As of this version, this will not detect a default
- device switch when changed from the operating system's audio preferences (unless the backend itself handles
- this automatically). This is not supported in exclusive mode.
- - WASAPI and Core Audio: Add support for stream routing. When the application is using a default device and the
- user switches the default device via the operating system's audio preferences, miniaudio will automatically switch
- the internal device to the new default. This is not supported in exclusive mode.
- - WASAPI: Add support for hardware offloading via IAudioClient2. Only supported on Windows 8 and newer.
- - WASAPI: Add support for low-latency shared mode via IAudioClient3. Only supported on Windows 10 and newer.
- - Add support for compiling the UWP build as C.
- - mal_device_set_recv_callback() and mal_device_set_send_callback() have been deprecated. You must now set this
- when the device is initialized with mal_device_init*(). These will be removed in version 0.9.0.
-
-v0.8.5 - 2018-08-12
- - Add support for specifying the size of a device's buffer in milliseconds. You can still set the buffer size in
- frames if that suits you. When bufferSizeInFrames is 0, bufferSizeInMilliseconds will be used. If both are non-0
- then bufferSizeInFrames will take priority. If both are set to 0 the default buffer size is used.
- - Add support for the audio(4) backend to OpenBSD.
- - Fix a bug with the ALSA backend that was causing problems on Raspberry Pi. This significantly improves the
- Raspberry Pi experience.
- - Fix a bug where an incorrect number of samples is returned from sinc resampling.

- - Add audio(4) backend for NetBSD.
- - Drop support for the OSS backend on everything except FreeBSD and DragonFly BSD.
- - Formats are now native-endian (were previously little-endian).

- - mal_dsp_set_input_sample_rate() and mal_dsp_set_output_sample_rate() are replaced with mal_dsp_set_sample_rate().
- - Fix a bug when capturing using the WASAPI backend.
- - Fix some aliasing issues with resampling, specifically when increasing the sample rate.
- - Fix warnings.
-
-v0.8.3 - 2018-07-15
- - Fix a crackling bug when resampling in capture mode.
- - Core Audio: Fix a bug where capture does not work.
- - ALSA: Fix a bug where the worker thread can get stuck in an infinite loop.
- - PulseAudio: Fix a bug where mal_context_init() succeeds when PulseAudio is unusable.
- - JACK: Fix a bug where mal_context_init() succeeds when JACK is unusable.
-
-v0.8.2 - 2018-07-07
- - Fix a bug on macOS with Core Audio where the internal callback is not called.
-
-v0.8.1 - 2018-07-06
- - Fix compilation errors and warnings.
-
-v0.8 - 2018-07-05
- - Changed MAL_IMPLEMENTATION to MINI_AL_IMPLEMENTATION for consistency with other libraries. The old
- way is still supported for now, but you should update as it may be removed in the future.
- - API CHANGE: Replace device enumeration APIs. mal_enumerate_devices() has been replaced with
- mal_context_get_devices(). An additional low-level device enumration API has been introduced called
- mal_context_enumerate_devices() which uses a callback to report devices.
- - API CHANGE: Rename mal_get_sample_size_in_bytes() to mal_get_bytes_per_sample() and add
- mal_get_bytes_per_frame().
- - API CHANGE: Replace mal_device_config.preferExclusiveMode with mal_device_config.shareMode.
- - This new config can be set to mal_share_mode_shared (default) or mal_share_mode_exclusive.
- - API CHANGE: Remove excludeNullDevice from mal_context_config.alsa.
- - API CHANGE: Rename MAL_MAX_SAMPLE_SIZE_IN_BYTES to MAL_MAX_PCM_SAMPLE_SIZE_IN_BYTES.
- - API CHANGE: Change the default channel mapping to the standard Microsoft mapping.
- - API CHANGE: Remove backend-specific result codes.
- - API CHANGE: Changes to the format conversion APIs (mal_pcm_f32_to_s16(), etc.)
- - Add support for Core Audio (Apple).
- - Add support for PulseAudio.
- - This is the highest priority backend on Linux (higher priority than ALSA) since it is commonly
- installed by default on many of the popular distros and offer's more seamless integration on
- platforms where PulseAudio is used. In addition, if PulseAudio is installed and running (which
- is extremely common), it's better to just use PulseAudio directly rather than going through the
- "pulse" ALSA plugin (which is what the "default" ALSA device is likely set to).
- - Add support for JACK.
- - Remove dependency on asound.h for the ALSA backend. This means the ALSA development packages are no
- longer required to build miniaudio.
- - Remove dependency on dsound.h for the DirectSound backend. This fixes build issues with some
- distributions of MinGW.
- - Remove dependency on audioclient.h for the WASAPI backend. This fixes build issues with some
- distributions of MinGW.
- - Add support for dithering to format conversion.
- - Add support for configuring the priority of the worker thread.
- - Add a sine wave generator.
- - Improve efficiency of sample rate conversion.
- - Introduce the notion of standard channel maps. Use mal_get_standard_channel_map().
- - Introduce the notion of default device configurations. A default config uses the same configuration
- as the backend's internal device, and as such results in a pass-through data transmission pipeline.
- - Add support for passing in NULL for the device config in mal_device_init(), which uses a default
- config. This requires manually calling mal_device_set_send/recv_callback().
- - Add support for decoding from raw PCM data (mal_decoder_init_raw(), etc.)
- - Make mal_device_init_ex() more robust.
- - Make some APIs more const-correct.
- - Fix errors with SDL detection on Apple platforms.
- - Fix errors with OpenAL detection.
- - Fix some memory leaks.
- - Fix a bug with opening decoders from memory.
- - Early work on SSE2, AVX2 and NEON optimizations.
- - Miscellaneous bug fixes.
- - Documentation updates.
-
-v0.7 - 2018-02-25
- - API CHANGE: Change mal_src_read_frames() and mal_dsp_read_frames() to use 64-bit sample counts.
- - Add decoder APIs for loading WAV, FLAC, Vorbis and MP3 files.
- - Allow opening of devices without a context.
- - In this case the context is created and managed internally by the device.
- - Change the default channel mapping to the same as that used by FLAC.
- - Fix build errors with macOS.
-
-v0.6c - 2018-02-12
- - Fix build errors with BSD/OSS.
-
-v0.6b - 2018-02-03
- - Fix some warnings when compiling with Visual C++.
-
-v0.6a - 2018-01-26
- - Fix errors with channel mixing when increasing the channel count.
- - Improvements to the build system for the OpenAL backend.
- - Documentation fixes.
-
-v0.6 - 2017-12-08
- - API CHANGE: Expose and improve mutex APIs. If you were using the mutex APIs before this version you'll
- need to update.
- - API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively.
- - API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent.
- - Add support for SDL and Emscripten.
- - Simplify the build system further for when development packages for various backends are not installed.
- With this change, when the compiler supports __has_include, backends without the relevant development
- packages installed will be ignored. This fixes the build for old versions of MinGW.
- - Fixes to the Android build.
- - Add mal_convert_frames(). This is a high-level helper API for performing a one-time, bulk conversion of
- audio data to a different format.
- - Improvements to f32 -> u8/s16/s24/s32 conversion routines.
- - Fix a bug where the wrong value is returned from mal_device_start() for the OpenSL backend.
- - Fixes and improvements for Raspberry Pi.
- - Warning fixes.
-
-v0.5 - 2017-11-11
- - API CHANGE: The mal_context_init() function now takes a pointer to a mal_context_config object for
- configuring the context. The works in the same kind of way as the device config. The rationale for this
- change is to give applications better control over context-level properties, add support for backend-
- specific configurations, and support extensibility without breaking the API.
- - API CHANGE: The alsa.preferPlugHW device config variable has been removed since it's not really useful for
- anything anymore.
- - ALSA: By default, device enumeration will now only enumerate over unique card/device pairs. Applications
- can enable verbose device enumeration by setting the alsa.useVerboseDeviceEnumeration context config
- variable.
- - ALSA: When opening a device in shared mode (the default), the dmix/dsnoop plugin will be prioritized. If
- this fails it will fall back to the hw plugin. With this change the preferExclusiveMode config is now
- honored. Note that this does not happen when alsa.useVerboseDeviceEnumeration is set to true (see above)
- which is by design.
- - ALSA: Add support for excluding the "null" device using the alsa.excludeNullDevice context config variable.
- - ALSA: Fix a bug with channel mapping which causes an assertion to fail.
- - Fix errors with enumeration when pInfo is set to NULL.
- - OSS: Fix a bug when starting a device when the client sends 0 samples for the initial buffer fill.
-
-v0.4 - 2017-11-05
- - API CHANGE: The log callback is now per-context rather than per-device and as is thus now passed to
- mal_context_init(). The rationale for this change is that it allows applications to capture diagnostic
- messages at the context level. Previously this was only available at the device level.
- - API CHANGE: The device config passed to mal_device_init() is now const.
- - Added support for OSS which enables support on BSD platforms.
- - Added support for WinMM (waveOut/waveIn).
- - Added support for UWP (Universal Windows Platform) applications. Currently C++ only.
- - Added support for exclusive mode for selected backends. Currently supported on WASAPI.
- - POSIX builds no longer require explicit linking to libpthread (-lpthread).
- - ALSA: Explicit linking to libasound (-lasound) is no longer required.
- - ALSA: Latency improvements.
- - ALSA: Use MMAP mode where available. This can be disabled with the alsa.noMMap config.
- - ALSA: Use "hw" devices instead of "plughw" devices by default. This can be disabled with the
- alsa.preferPlugHW config.
- - WASAPI is now the highest priority backend on Windows platforms.
- - Fixed an error with sample rate conversion which was causing crackling when capturing.
- - Improved error handling.
- - Improved compiler support.
- - Miscellaneous bug fixes.
-
-v0.3 - 2017-06-19
- - API CHANGE: Introduced the notion of a context. The context is the highest level object and is required for
- enumerating and creating devices. Now, applications must first create a context, and then use that to
- enumerate and create devices. The reason for this change is to ensure device enumeration and creation is
- tied to the same backend. In addition, some backends are better suited to this design.
- - API CHANGE: Removed the rewinding APIs because they're too inconsistent across the different backends, hard
- to test and maintain, and just generally unreliable.
- - Added helper APIs for initializing mal_device_config objects.
- - Null Backend: Fixed a crash when recording.
- - Fixed build for UWP.
- - Added support for f32 formats to the OpenSL|ES backend.
- - Added initial implementation of the WASAPI backend.
- - Added initial implementation of the OpenAL backend.
- - Added support for low quality linear sample rate conversion.
- - Added early support for basic channel mapping.
-
-v0.2 - 2016-10-28
- - API CHANGE: Add user data pointer as the last parameter to mal_device_init(). The rationale for this
- change is to ensure the logging callback has access to the user data during initialization.
- - API CHANGE: Have device configuration properties be passed to mal_device_init() via a structure. Rationale:
- 1) The number of parameters is just getting too much.
- 2) It makes it a bit easier to add new configuration properties in the future. In particular, there's a
- chance there will be support added for backend-specific properties.
- - Dropped support for f64, A-law and Mu-law formats since they just aren't common enough to justify the
- added maintenance cost.
- - DirectSound: Increased the default buffer size for capture devices.
- - Added initial implementation of the OpenSL|ES backend.
-
-v0.1 - 2016-10-21
- - Initial versioned release.

-HOW TO USE:
-
- In exactly one translation unit (.c or .cpp file), #define MSF_GIF_IMPL before including the header, like so:
-
- #define MSF_GIF_IMPL
- #include "msf_gif.h"
-
- Everywhere else, just include the header like normal.
-
-
-USAGE EXAMPLE:
-
- int width = 480, height = 320, centisecondsPerFrame = 5, bitDepth = 16;
- MsfGifState gifState = {};
- msf_gif_begin(&gifState, width, height);
- msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 1
- msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 2
- msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 3, etc...
- MsfGifResult result = msf_gif_end(&gifState);
- FILE * fp = fopen("MyGif.gif", "wb");
- fwrite(result.data, result.dataSize, 1, fp);
- fclose(fp);
- msf_gif_free(result);
-
-Detailed function documentation can be found in the header section below.
-
-
-REPLACING MALLOC:
-
- This library uses malloc+realloc+free internally for memory allocation.
- To facilitate integration with custom memory allocators, these calls go through macros, which can be redefined.
- The expected function signature equivalents of the macros are as follows:
-
- void * MSF_GIF_MALLOC(void * context, size_t newSize)
- void * MSF_GIF_REALLOC(void * context, void * oldMemory, size_t oldSize, size_t newSize)
- void MSF_GIF_FREE(void * context, void * oldMemory, size_t oldSize)
-
- If your allocator needs a context pointer, you can set the `customAllocatorContext` field of the MsfGifState struct
- before calling msf_gif_begin(), and it will be passed to all subsequent allocator macro calls.
-
-See end of file for license information.

-// SHAPES :: https://github.com/prideout/par
-// Simple C library for creation and manipulation of triangle meshes.
-//
-// The API is divided into three sections:
-//
-// - Generators. Create parametric surfaces, platonic solids, etc.
-// - Queries. Ask a mesh for its axis-aligned bounding box, etc.
-// - Transforms. Rotate a mesh, merge it with another, add normals, etc.
-//
-// In addition to the comment block above each function declaration, the API
-// has informal documentation here:
-//
-// https://prideout.net/shapes
-//
-// For our purposes, a "mesh" is a list of points and a list of triangles; the
-// former is a flattened list of three-tuples (32-bit floats) and the latter is
-// also a flattened list of three-tuples (16-bit uints). Triangles are always
-// oriented such that their front face winds counter-clockwise.
-//
-// Optionally, meshes can contain 3D normals (one per vertex), and 2D texture
-// coordinates (one per vertex). That's it! If you need something fancier,
-// look elsewhere.

-# Small Deflate
-`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
-which implements the Deflate (RFC 1951) compressed data format specification standard.
-It is mainly tuned to get as much speed and compression ratio from as little code
-as needed to keep the implementation as concise as possible.
-
-## Features
-- Portable single header and source file duo written in ANSI C (ISO C90)
-- Dual license with either MIT or public domain
-- Small implementation
- - Deflate: 525 LoC
- - Inflate: 320 LoC
-- Webassembly:
- - Deflate ~3.7 KB (~2.2KB compressed)
- - Inflate ~3.6 KB (~2.2KB compressed)
-
-## Usage:
-This file behaves differently depending on what symbols you define
-before including it.
-
-Header-File mode:
-If you do not define `SDEFL_IMPLEMENTATION` before including this file, it
-will operate in header only mode. In this mode it declares all used structs
-and the API of the library without including the implementation of the library.
-
-Implementation mode:
-If you define `SDEFL_IMPLEMENTATION` before including this file, it will
-compile the implementation . Make sure that you only include
-this file implementation in *one* C or C++ file to prevent collisions.

-# Small Deflate
-`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
-which implements the Deflate (RFC 1951) compressed data format specification standard.
-It is mainly tuned to get as much speed and compression ratio from as little code
-as needed to keep the implementation as concise as possible.
-
-## Features
-- Portable single header and source file duo written in ANSI C (ISO C90)
-- Dual license with either MIT or public domain
-- Small implementation
- - Deflate: 525 LoC
- - Inflate: 320 LoC
-- Webassembly:
- - Deflate ~3.7 KB (~2.2KB compressed)
- - Inflate ~3.6 KB (~2.2KB compressed)
-
-## Usage:
-This file behaves differently depending on what symbols you define
-before including it.
-
-Header-File mode:
-If you do not define `SINFL_IMPLEMENTATION` before including this file, it
-will operate in header only mode. In this mode it declares all used structs
-and the API of the library without including the implementation of the library.
-
-Implementation mode:
-If you define `SINFL_IMPLEMENTATION` before including this file, it will
-compile the implementation. Make sure that you only include
-this file implementation in *one* C or C++ file to prevent collisions.

-
-// DOCUMENTATION
-//
-// Limitations:
-// - no 12-bit-per-channel JPEG
-// - no JPEGs with arithmetic coding
-// - GIF always returns *comp=4
-//
-// Basic usage (see HDR discussion below for HDR usage):
-// int x,y,n;
-// unsigned char *data = stbi_load(filename, &x, &y, &n, 0);
-// // ... process data if not NULL ...
-// // ... x = width, y = height, n = # 8-bit components per pixel ...
-// // ... replace '0' with '1'..'4' to force that many components per pixel
-// // ... but 'n' will always be the number that it would have been if you said 0
-// stbi_image_free(data)
-//
-// Standard parameters:
-// int *x -- outputs image width in pixels
-// int *y -- outputs image height in pixels
-// int *channels_in_file -- outputs # of image components in image file
-// int desired_channels -- if non-zero, # of image components requested in result
-//
-// The return value from an image loader is an 'unsigned char *' which points
-// to the pixel data, or NULL on an allocation failure or if the image is
-// corrupt or invalid. The pixel data consists of *y scanlines of *x pixels,
-// with each pixel consisting of N interleaved 8-bit components; the first
-// pixel pointed to is top-left-most in the image. There is no padding between
-// image scanlines or between pixels, regardless of format. The number of
-// components N is 'desired_channels' if desired_channels is non-zero, or
-// *channels_in_file otherwise. If desired_channels is non-zero,
-// *channels_in_file has the number of components that _would_ have been
-// output otherwise. E.g. if you set desired_channels to 4, you will always
-// get RGBA output, but you can check *channels_in_file to see if it's trivially
-// opaque because e.g. there were only 3 channels in the source image.
-//
-// An output image with N components has the following components interleaved
-// in this order in each pixel:
-//
-// N=#comp components
-// 1 grey
-// 2 grey, alpha
-// 3 red, green, blue
-// 4 red, green, blue, alpha
-//
-// If image loading fails for any reason, the return value will be NULL,
-// and *x, *y, *channels_in_file will be unchanged. The function
-// stbi_failure_reason() can be queried for an extremely brief, end-user
-// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS
-// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly
-// more user-friendly ones.
-//
-// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized.
-//
-// ===========================================================================
-//
-// UNICODE:
-//
-// If compiling for Windows and you wish to use Unicode filenames, compile
-// with
-// #define STBI_WINDOWS_UTF8
-// and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert
-// Windows wchar_t filenames to utf8.
-//
-// ===========================================================================
-//
-// Philosophy
-//
-// stb libraries are designed with the following priorities:
-//
-// 1. easy to use
-// 2. easy to maintain
-// 3. good performance
-//
-// Sometimes I let "good performance" creep up in priority over "easy to maintain",
-// and for best performance I may provide less-easy-to-use APIs that give higher
-// performance, in addition to the easy-to-use ones. Nevertheless, it's important
-// to keep in mind that from the standpoint of you, a client of this library,
-// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all.
-//
-// Some secondary priorities arise directly from the first two, some of which
-// provide more explicit reasons why performance can't be emphasized.
-//
-// - Portable ("ease of use")
-// - Small source code footprint ("easy to maintain")
-// - No dependencies ("ease of use")
-//
-// ===========================================================================
-//
-// I/O callbacks
-//
-// I/O callbacks allow you to read from arbitrary sources, like packaged
-// files or some other source. Data read from callbacks are processed
-// through a small internal buffer (currently 128 bytes) to try to reduce
-// overhead.
-//
-// The three functions you must define are "read" (reads some bytes of data),
-// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end).
-//
-// ===========================================================================
-//
-// SIMD support
-//
-// The JPEG decoder will try to automatically use SIMD kernels on x86 when
-// supported by the compiler. For ARM Neon support, you must explicitly
-// request it.
-//
-// (The old do-it-yourself SIMD API is no longer supported in the current
-// code.)
-//
-// On x86, SSE2 will automatically be used when available based on a run-time
-// test; if not, the generic C versions are used as a fall-back. On ARM targets,
-// the typical path is to have separate builds for NEON and non-NEON devices
-// (at least this is true for iOS and Android). Therefore, the NEON support is
-// toggled by a build flag: define STBI_NEON to get NEON loops.
-//
-// If for some reason you do not want to use any of SIMD code, or if
-// you have issues compiling it, you can disable it entirely by
-// defining STBI_NO_SIMD.
-//
-// ===========================================================================
-//
-// HDR image support (disable by defining STBI_NO_HDR)
-//
-// stb_image supports loading HDR images in general, and currently the Radiance
-// .HDR file format specifically. You can still load any file through the existing
-// interface; if you attempt to load an HDR file, it will be automatically remapped
-// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;
-// both of these constants can be reconfigured through this interface:
-//
-// stbi_hdr_to_ldr_gamma(2.2f);
-// stbi_hdr_to_ldr_scale(1.0f);
-//
-// (note, do not use _inverse_ constants; stbi_image will invert them
-// appropriately).
-//
-// Additionally, there is a new, parallel interface for loading files as
-// (linear) floats to preserve the full dynamic range:
-//
-// float *data = stbi_loadf(filename, &x, &y, &n, 0);
-//
-// If you load LDR images through this interface, those images will
-// be promoted to floating point values, run through the inverse of
-// constants corresponding to the above:
-//
-// stbi_ldr_to_hdr_scale(1.0f);
-// stbi_ldr_to_hdr_gamma(2.2f);
-//
-// Finally, given a filename (or an open file or memory block--see header
-// file for details) containing image data, you can query for the "most
-// appropriate" interface to use (that is, whether the image is HDR or
-// not), using:
-//
-// stbi_is_hdr(char *filename);
-//
-// ===========================================================================
-//
-// iPhone PNG support:
-//
-// By default we convert iphone-formatted PNGs back to RGB, even though
-// they are internally encoded differently. You can disable this conversion
-// by calling stbi_convert_iphone_png_to_rgb(0), in which case
-// you will always just get the native iphone "format" through (which
-// is BGR stored in RGB).
-//
-// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per
-// pixel to remove any premultiplied alpha *only* if the image file explicitly
-// says there's premultiplied data (currently only happens in iPhone images,
-// and only if iPhone convert-to-rgb processing is on).
-//
-// ===========================================================================
-//
-// ADDITIONAL CONFIGURATION
-//
-// - You can suppress implementation of any of the decoders to reduce
-// your code footprint by #defining one or more of the following
-// symbols before creating the implementation.
-//
-// STBI_NO_JPEG
-// STBI_NO_PNG
-// STBI_NO_BMP
-// STBI_NO_PSD
-// STBI_NO_TGA
-// STBI_NO_GIF
-// STBI_NO_HDR
-// STBI_NO_PIC
-// STBI_NO_PNM (.ppm and .pgm)
-//
-// - You can request *only* certain decoders and suppress all other ones
-// (this will be more forward-compatible, as addition of new decoders
-// doesn't require you to disable them explicitly):
-//
-// STBI_ONLY_JPEG
-// STBI_ONLY_PNG
-// STBI_ONLY_BMP
-// STBI_ONLY_PSD
-// STBI_ONLY_TGA
-// STBI_ONLY_GIF
-// STBI_ONLY_HDR
-// STBI_ONLY_PIC
-// STBI_ONLY_PNM (.ppm and .pgm)
-//
-// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still
-// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB
-//
-// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater
-// than that size (in either width or height) without further processing.
-// This is to let programs in the wild set an upper bound to prevent
-// denial-of-service attacks on untrusted data, as one could generate a
-// valid image of gigantic dimensions and force stb_image to allocate a
-// huge block of memory and spend disproportionate time decoding it. By
-// default this is set to (1 << 24), which is 16777216, but that's still
-// very big.

-/* stb_image_resize - v0.96 - public domain image resizing
- by Jorge L Rodriguez (@VinoBS) - 2014
- http://github.com/nothings/stb
-
- Written with emphasis on usability, portability, and efficiency. (No
- SIMD or threads, so it be easily outperformed by libs that use those.)
- Only scaling and translation is supported, no rotations or shears.
- Easy API downsamples w/Mitchell filter, upsamples w/cubic interpolation.
-
- COMPILING & LINKING
- In one C/C++ file that #includes this file, do this:
- #define STB_IMAGE_RESIZE_IMPLEMENTATION
- before the #include. That will create the implementation in that file.
-
- QUICKSTART
- stbir_resize_uint8( input_pixels , in_w , in_h , 0,
- output_pixels, out_w, out_h, 0, num_channels)
- stbir_resize_float(...)
- stbir_resize_uint8_srgb( input_pixels , in_w , in_h , 0,
- output_pixels, out_w, out_h, 0,
- num_channels , alpha_chan , 0)
- stbir_resize_uint8_srgb_edgemode(
- input_pixels , in_w , in_h , 0,
- output_pixels, out_w, out_h, 0,
- num_channels , alpha_chan , 0, STBIR_EDGE_CLAMP)
- // WRAP/REFLECT/ZERO
-
- FULL API
- See the "header file" section of the source for API documentation.
-
- ADDITIONAL DOCUMENTATION
-
- SRGB & FLOATING POINT REPRESENTATION
- The sRGB functions presume IEEE floating point. If you do not have
- IEEE floating point, define STBIR_NON_IEEE_FLOAT. This will use
- a slower implementation.
-
- MEMORY ALLOCATION
- The resize functions here perform a single memory allocation using
- malloc. To control the memory allocation, before the #include that
- triggers the implementation, do:
-
- #define STBIR_MALLOC(size,context) ...
- #define STBIR_FREE(ptr,context) ...
-
- Each resize function makes exactly one call to malloc/free, so to use
- temp memory, store the temp memory in the context and return that.
-
- ASSERT
- Define STBIR_ASSERT(boolval) to override assert() and not use assert.h
-
- OPTIMIZATION
- Define STBIR_SATURATE_INT to compute clamp values in-range using
- integer operations instead of float operations. This may be faster
- on some platforms.
-
- DEFAULT FILTERS
- For functions which don't provide explicit control over what filters
- to use, you can change the compile-time defaults with
-
- #define STBIR_DEFAULT_FILTER_UPSAMPLE STBIR_FILTER_something
- #define STBIR_DEFAULT_FILTER_DOWNSAMPLE STBIR_FILTER_something
-
- See stbir_filter in the header-file section for the list of filters.
-
- NEW FILTERS
- A number of 1D filter kernels are used. For a list of
- supported filters see the stbir_filter enum. To add a new filter,
- write a filter function and add it to stbir__filter_info_table.
-
- PROGRESS
- For interactive use with slow resize operations, you can install
- a progress-report callback:
-
- #define STBIR_PROGRESS_REPORT(val) some_func(val)
-
- The parameter val is a float which goes from 0 to 1 as progress is made.
-
- For example:
-
- static void my_progress_report(float progress);
- #define STBIR_PROGRESS_REPORT(val) my_progress_report(val)
-
- #define STB_IMAGE_RESIZE_IMPLEMENTATION
- #include "stb_image_resize.h"
-
- static void my_progress_report(float progress)
- {
- printf("Progress: %f%%\n", progress*100);
- }
-
- MAX CHANNELS
- If your image has more than 64 channels, define STBIR_MAX_CHANNELS
- to the max you'll have.
-
- ALPHA CHANNEL
- Most of the resizing functions provide the ability to control how
- the alpha channel of an image is processed. The important things
- to know about this:
-
- 1. The best mathematically-behaved version of alpha to use is
- called "premultiplied alpha", in which the other color channels
- have had the alpha value multiplied in. If you use premultiplied
- alpha, linear filtering (such as image resampling done by this
- library, or performed in texture units on GPUs) does the "right
- thing". While premultiplied alpha is standard in the movie CGI
- industry, it is still uncommon in the videogame/real-time world.
-
- If you linearly filter non-premultiplied alpha, strange effects
- occur. (For example, the 50/50 average of 99% transparent bright green
- and 1% transparent black produces 50% transparent dark green when
- non-premultiplied, whereas premultiplied it produces 50%
- transparent near-black. The former introduces green energy
- that doesn't exist in the source image.)
-
- 2. Artists should not edit premultiplied-alpha images; artists
- want non-premultiplied alpha images. Thus, art tools generally output
- non-premultiplied alpha images.
-
- 3. You will get best results in most cases by converting images
- to premultiplied alpha before processing them mathematically.
-
- 4. If you pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, the
- resizer does not do anything special for the alpha channel;
- it is resampled identically to other channels. This produces
- the correct results for premultiplied-alpha images, but produces
- less-than-ideal results for non-premultiplied-alpha images.
-
- 5. If you do not pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED,
- then the resizer weights the contribution of input pixels
- based on their alpha values, or, equivalently, it multiplies
- the alpha value into the color channels, resamples, then divides
- by the resultant alpha value. Input pixels which have alpha=0 do
- not contribute at all to output pixels unless _all_ of the input
- pixels affecting that output pixel have alpha=0, in which case
- the result for that pixel is the same as it would be without
- STBIR_FLAG_ALPHA_PREMULTIPLIED. However, this is only true for
- input images in integer formats. For input images in float format,
- input pixels with alpha=0 have no effect, and output pixels
- which have alpha=0 will be 0 in all channels. (For float images,
- you can manually achieve the same result by adding a tiny epsilon
- value to the alpha channel of every image, and then subtracting
- or clamping it at the end.)
-
- 6. You can suppress the behavior described in #5 and make
- all-0-alpha pixels have 0 in all channels by #defining
- STBIR_NO_ALPHA_EPSILON.
-
- 7. You can separately control whether the alpha channel is
- interpreted as linear or affected by the colorspace. By default
- it is linear; you almost never want to apply the colorspace.
- (For example, graphics hardware does not apply sRGB conversion
- to the alpha channel.)

-// * input_w is input image width (x-axis), input_h is input image height (y-axis)
-// * stride is the offset between successive rows of image data in memory, in bytes. you can
-// specify 0 to mean packed continuously in memory
-// * alpha channel is treated identically to other channels.
-// * colorspace is linear or sRGB as specified by function name
-// * returned result is 1 for success or 0 in case of an error.
-// #define STBIR_ASSERT() to trigger an assert on parameter validation errors.
-// * Memory required grows approximately linearly with input and output size, but with
-// discontinuities at input_w == output_w and input_h == output_h.
-// * These functions use a "default" resampling filter defined at compile time. To change the filter,
-// you can change the compile-time defaults by #defining STBIR_DEFAULT_FILTER_UPSAMPLE
-// and STBIR_DEFAULT_FILTER_DOWNSAMPLE, or you can use the medium-complexity API.

-/* stb_image_write - v1.15 - public domain - http://nothings.org/stb
- writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
- no warranty implied; use at your own risk
-
- Before #including,
-
- #define STB_IMAGE_WRITE_IMPLEMENTATION
-
- in the file that you want to have the implementation.
-
- Will probably not work correctly with strict-aliasing optimizations.
-
-ABOUT:
-
- This header file is a library for writing images to C stdio or a callback.
-
- The PNG output is not optimal; it is 20-50% larger than the file
- written by a decent optimizing implementation; though providing a custom
- zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that.
- This library is designed for source code compactness and simplicity,
- not optimal image file size or run-time performance.
-
-BUILDING:
-
- You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
- You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
- malloc,realloc,free.
- You can #define STBIW_MEMMOVE() to replace memmove()
- You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function
- for PNG compression (instead of the builtin one), it must have the following signature:
- unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality);
- The returned data will be freed with STBIW_FREE() (free() by default),
- so it must be heap allocated with STBIW_MALLOC() (malloc() by default),
-
-UNICODE:
-
- If compiling for Windows and you wish to use Unicode filenames, compile
- with
- #define STBIW_WINDOWS_UTF8
- and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert
- Windows wchar_t filenames to utf8.
-
-USAGE:
-
- There are five functions, one for each image file format:
-
- int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
- int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
- int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
- int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality);
- int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
-
- void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
-
- There are also five equivalent functions that use an arbitrary write function. You are
- expected to open/close your file-equivalent before and after calling these:
-
- int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes);
- int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
- int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
- int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
- int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
-
- where the callback is:
- void stbi_write_func(void *context, void *data, int size);
-
- You can configure it with these global variables:
- int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE
- int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression
- int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode
-
-
- You can define STBI_WRITE_NO_STDIO to disable the file variant of these
- functions, so the library will not use stdio.h at all. However, this will
- also disable HDR writing, because it requires stdio for formatted output.
-
- Each function returns 0 on failure and non-0 on success.
-
- The functions create an image file defined by the parameters. The image
- is a rectangle of pixels stored from left-to-right, top-to-bottom.
- Each pixel contains 'comp' channels of data stored interleaved with 8-bits
- per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
- monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
- The *data pointer points to the first byte of the top-left-most pixel.
- For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
- a row of pixels to the first byte of the next row of pixels.
-
- PNG creates output files with the same number of components as the input.
- The BMP format expands Y to RGB in the file format and does not
- output alpha.
-
- PNG supports writing rectangles of data even when the bytes storing rows of
- data are not consecutive in memory (e.g. sub-rectangles of a larger image),
- by supplying the stride between the beginning of adjacent rows. The other
- formats do not. (Thus you cannot write a native-format BMP through the BMP
- writer, both because it is in BGR order and because it may have padding
- at the end of the line.)
-
- PNG allows you to set the deflate compression level by setting the global
- variable 'stbi_write_png_compression_level' (it defaults to 8).
-
- HDR expects linear float data. Since the format is always 32-bit rgb(e)
- data, alpha (if provided) is discarded, and for monochrome data it is
- replicated across all three channels.
-
- TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
- data, set the global variable 'stbi_write_tga_with_rle' to 0.
-
- JPEG does ignore alpha channels in input data; quality is between 1 and 100.
- Higher quality looks better but results in a bigger image.
- JPEG baseline (no JPEG progressive).

-// stb_perlin.h - v0.5 - perlin noise
-// public domain single-file C implementation by Sean Barrett
-//
-// LICENSE
-//
-// See end of file.
-//
-//
-// to create the implementation,
-// #define STB_PERLIN_IMPLEMENTATION
-// in *one* C/CPP file that includes this file.
-//
-//
-// Documentation:
-//
-// float stb_perlin_noise3( float x,
-// float y,
-// float z,
-// int x_wrap=0,
-// int y_wrap=0,
-// int z_wrap=0)
-//
-// This function computes a random value at the coordinate (x,y,z).
-// Adjacent random values are continuous but the noise fluctuates
-// its randomness with period 1, i.e. takes on wholly unrelated values
-// at integer points. Specifically, this implements Ken Perlin's
-// revised noise function from 2002.
-//
-// The "wrap" parameters can be used to create wraparound noise that
-// wraps at powers of two. The numbers MUST be powers of two. Specify
-// 0 to mean "don't care". (The noise always wraps every 256 due
-// details of the implementation, even if you ask for larger or no
-// wrapping.)
-//
-// float stb_perlin_noise3_seed( float x,
-// float y,
-// float z,
-// int x_wrap=0,
-// int y_wrap=0,
-// int z_wrap=0,
-// int seed)
-//
-// As above, but 'seed' selects from multiple different variations of the
-// noise function. The current implementation only uses the bottom 8 bits
-// of 'seed', but possibly in the future more bits will be used.
-//
-//
-// Fractal Noise:
-//
-// Three common fractal noise functions are included, which produce
-// a wide variety of nice effects depending on the parameters
-// provided. Note that each function will call stb_perlin_noise3
-// 'octaves' times, so this parameter will affect runtime.
-//
-// float stb_perlin_ridge_noise3(float x, float y, float z,
-// float lacunarity, float gain, float offset, int octaves)
-//
-// float stb_perlin_fbm_noise3(float x, float y, float z,
-// float lacunarity, float gain, int octaves)
-//
-// float stb_perlin_turbulence_noise3(float x, float y, float z,
-// float lacunarity, float gain, int octaves)
-//
-// Typical values to start playing with:
-// octaves = 6 -- number of "octaves" of noise3() to sum
-// lacunarity = ~ 2.0 -- spacing between successive octaves (use exactly 2.0 for wrapping output)
-// gain = 0.5 -- relative weighting applied to each successive octave
-// offset = 1.0? -- used to invert the ridges, may need to be larger, not sure
-//
-//
-// Contributors:
-// Jack Mott - additional noise functions
-// Jordan Peck - seeded noise

-// stb_rect_pack.h - v1.00 - public domain - rectangle packing
-// Sean Barrett 2014
-//
-// Useful for e.g. packing rectangular textures into an atlas.
-// Does not do rotation.
-//
-// Not necessarily the awesomest packing method, but better than
-// the totally naive one in stb_truetype (which is primarily what
-// this is meant to replace).
-//
-// Has only had a few tests run, may have issues.
-//
-// More docs to come.
-//
-// No memory allocations; uses qsort() and assert() from stdlib.
-// Can override those by defining STBRP_SORT and STBRP_ASSERT.
-//
-// This library currently uses the Skyline Bottom-Left algorithm.
-//
-// Please note: better rectangle packers are welcome! Please
-// implement them to the same API, but with a different init
-// function.

-//
-// USAGE
-//
-// Include this file in whatever places need to refer to it. In ONE C/C++
-// file, write:
-// #define STB_TRUETYPE_IMPLEMENTATION
-// before the #include of this file. This expands out the actual
-// implementation into that C/C++ file.
-//
-// To make the implementation private to the file that generates the implementation,
-// #define STBTT_STATIC
-//
-// Simple 3D API (don't ship this, but it's fine for tools and quick start)
-// stbtt_BakeFontBitmap() -- bake a font to a bitmap for use as texture
-// stbtt_GetBakedQuad() -- compute quad to draw for a given char
-//
-// Improved 3D API (more shippable):
-// #include "stb_rect_pack.h" -- optional, but you really want it
-// stbtt_PackBegin()
-// stbtt_PackSetOversampling() -- for improved quality on small fonts
-// stbtt_PackFontRanges() -- pack and renders
-// stbtt_PackEnd()
-// stbtt_GetPackedQuad()
-//
-// "Load" a font file from a memory buffer (you have to keep the buffer loaded)
-// stbtt_InitFont()
-// stbtt_GetFontOffsetForIndex() -- indexing for TTC font collections
-// stbtt_GetNumberOfFonts() -- number of fonts for TTC font collections
-//
-// Render a unicode codepoint to a bitmap
-// stbtt_GetCodepointBitmap() -- allocates and returns a bitmap
-// stbtt_MakeCodepointBitmap() -- renders into bitmap you provide
-// stbtt_GetCodepointBitmapBox() -- how big the bitmap must be
-//
-// Character advance/positioning
-// stbtt_GetCodepointHMetrics()
-// stbtt_GetFontVMetrics()
-// stbtt_GetFontVMetricsOS2()
-// stbtt_GetCodepointKernAdvance()
-//
-// Starting with version 1.06, the rasterizer was replaced with a new,
-// faster and generally-more-precise rasterizer. The new rasterizer more
-// accurately measures pixel coverage for anti-aliasing, except in the case
-// where multiple shapes overlap, in which case it overestimates the AA pixel
-// coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
-// this turns out to be a problem, you can re-enable the old rasterizer with
-// #define STBTT_RASTERIZER_VERSION 1
-// which will incur about a 15% speed hit.
-//
-// ADDITIONAL DOCUMENTATION
-//
-// Immediately after this block comment are a series of sample programs.
-//
-// After the sample programs is the "header file" section. This section
-// includes documentation for each API function.
-//
-// Some important concepts to understand to use this library:
-//
-// Codepoint
-// Characters are defined by unicode codepoints, e.g. 65 is
-// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
-// the hiragana for "ma".
-//
-// Glyph
-// A visual character shape (every codepoint is rendered as
-// some glyph)
-//
-// Glyph index
-// A font-specific integer ID representing a glyph
-//
-// Baseline
-// Glyph shapes are defined relative to a baseline, which is the
-// bottom of uppercase characters. Characters extend both above
-// and below the baseline.
-//
-// Current Point
-// As you draw text to the screen, you keep track of a "current point"
-// which is the origin of each character. The current point's vertical
-// position is the baseline. Even "baked fonts" use this model.
-//
-// Vertical Font Metrics
-// The vertical qualities of the font, used to vertically position
-// and space the characters. See docs for stbtt_GetFontVMetrics.
-//
-// Font Size in Pixels or Points
-// The preferred interface for specifying font sizes in stb_truetype
-// is to specify how tall the font's vertical extent should be in pixels.
-// If that sounds good enough, skip the next paragraph.
-//
-// Most font APIs instead use "points", which are a common typographic
-// measurement for describing font size, defined as 72 points per inch.
-// stb_truetype provides a point API for compatibility. However, true
-// "per inch" conventions don't make much sense on computer displays
-// since different monitors have different number of pixels per
-// inch. For example, Windows traditionally uses a convention that
-// there are 96 pixels per inch, thus making 'inch' measurements have
-// nothing to do with inches, and thus effectively defining a point to
-// be 1.333 pixels. Additionally, the TrueType font data provides
-// an explicit scale factor to scale a given font's glyphs to points,
-// but the author has observed that this scale factor is often wrong
-// for non-commercial fonts, thus making fonts scaled in points
-// according to the TrueType spec incoherently sized in practice.
-//
-// DETAILED USAGE:
-//
-// Scale:
-// Select how high you want the font to be, in points or pixels.
-// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
-// a scale factor SF that will be used by all other functions.
-//
-// Baseline:
-// You need to select a y-coordinate that is the baseline of where
-// your text will appear. Call GetFontBoundingBox to get the baseline-relative
-// bounding box for all characters. SF*-y0 will be the distance in pixels
-// that the worst-case character could extend above the baseline, so if
-// you want the top edge of characters to appear at the top of the
-// screen where y=0, then you would set the baseline to SF*-y0.
-//
-// Current point:
-// Set the current point where the first character will appear. The
-// first character could extend left of the current point; this is font
-// dependent. You can either choose a current point that is the leftmost
-// point and hope, or add some padding, or check the bounding box or
-// left-side-bearing of the first character to be displayed and set
-// the current point based on that.
-//
-// Displaying a character:
-// Compute the bounding box of the character. It will contain signed values
-// relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
-// then the character should be displayed in the rectangle from
-// <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
-//
-// Advancing for the next character:
-// Call GlyphHMetrics, and compute 'current_point += SF * advance'.
-//
-//
-// ADVANCED USAGE
-//
-// Quality:
-//
-// - Use the functions with Subpixel at the end to allow your characters
-// to have subpixel positioning. Since the font is anti-aliased, not
-// hinted, this is very import for quality. (This is not possible with
-// baked fonts.)
-//
-// - Kerning is now supported, and if you're supporting subpixel rendering
-// then kerning is worth using to give your text a polished look.
-//
-// Performance:
-//
-// - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
-// if you don't do this, stb_truetype is forced to do the conversion on
-// every call.
-//
-// - There are a lot of memory allocations. We should modify it to take
-// a temp buffer and allocate from the temp buffer (without freeing),
-// should help performance a lot.
-//
-// NOTES
-//
-// The system uses the raw data found in the .ttf file without changing it
-// and without building auxiliary data structures. This is a bit inefficient
-// on little-endian systems (the data is big-endian), but assuming you're
-// caching the bitmaps or glyph shapes this shouldn't be a big deal.
-//
-// It appears to be very hard to programmatically determine what font a
-// given file is in a general way. I provide an API for this, but I don't
-// recommend it.
-//
-//
-// PERFORMANCE MEASUREMENTS FOR 1.06:
-//
-// 32-bit 64-bit
-// Previous release: 8.83 s 7.68 s
-// Pool allocations: 7.72 s 6.34 s
-// Inline sort : 6.54 s 5.65 s
-// New rasterizer : 5.63 s 5.00 s

-// which allows effects like bit outlines
-// onedge_value -- value 0-255 to test the SDF against to reconstruct the character (i.e. the isocontour of the character)
-// pixel_dist_scale -- what value the SDF should increase by when moving one SDF "pixel" away from the edge (on the 0..255 scale)
-// if positive, > onedge_value is inside; if negative, < onedge_value is inside
-// width,height -- output height & width of the SDF bitmap (including padding)
-// xoff,yoff -- output origin of the character
-// return value -- a 2D array of bytes 0..255, width*height in size
-//
-// pixel_dist_scale & onedge_value are a scale & bias that allows you to make
-// optimal use of the limited 0..255 for your application, trading off precision
-// and special effects. SDF values outside the range 0..255 are clamped to 0..255.
-//
-// Example:
-// scale = stbtt_ScaleForPixelHeight(22)
-// padding = 5
-// onedge_value = 180
-// pixel_dist_scale = 180/5.0 = 36.0
-//
-// This will create an SDF bitmap in which the character is about 22 pixels
-// high but the whole bitmap is about 22+5+5=32 pixels high. To produce a filled
-// shape, sample the SDF at each pixel and fill the pixel if the SDF value
-// is greater than or equal to 180/255. (You'll actually want to antialias,
-// which is beyond the scope of this example.) Additionally, you can compute
-// offset outlines (e.g. to stroke the character border inside & outside,
-// or only outside). For example, to fill outside the character up to 3 SDF
-// pixels, you would compare against (180-36.0*3)/255 = 72/255. The above
-// choice of variables maps a range from 5 pixels outside the shape to
-// 2 pixels inside the shape to 0..255; this is intended primarily for apply
-// outside effects only (the interior range is needed to allow proper
-// antialiasing of the font at *smaller* sizes)
-//
-// The function computes the SDF analytically at each SDF pixel, not by e.g.
-// building a higher-res bitmap and approximating it. In theory the quality
-// should be as high as possible for an SDF of this size & representation, but
-// unclear if this is true in practice (perhaps building a higher-res bitmap
-// and computing from that can allow drop-out prevention).
-//
-// The algorithm has not been optimized at all, so expect it to be slow
-// if computing lots of characters or very large sizes.

-// Finding the right font...
-//
-// You should really just solve this offline, keep your own tables
-// of what font is what, and don't try to get it out of the .ttf file.
-// That's because getting it out of the .ttf file is really hard, because
-// the names in the file can appear in many possible encodings, in many
-// possible languages, and e.g. if you need a case-insensitive comparison,
-// the details of that depend on the encoding & language in a complex way
-// (actually underspecified in truetype, but also gigantic).
-//
-// But you can use the provided functions in two possible ways:
-// stbtt_FindMatchingFont() will use *case-sensitive* comparisons on
-// unicode-encoded names to try to find the font you want;
-// you can run this before calling stbtt_InitFont()
-//
-// stbtt_GetFontNameString() lets you get any of the various strings
-// from the file yourself and do your own comparisons on them.
-// You have to have called stbtt_InitFont() first.
-
-
-STBTT_DEF int stbtt_FindMatchingFont(const unsigned char *fontdata, const char *name, int flags);
-// returns the offset (not index) of the font that matches, or -1 if none
-// if you use STBTT_MACSTYLE_DONTCARE, use a font name like "Arial Bold".
-// if you use any other flag, use a font name like "Arial"; this checks
-// the 'macStyle' header field; i don't know if fonts set this consistently

-/////////// THREAD SAFETY
-
-// Individual stb_vorbis* handles are not thread-safe; you cannot decode from
-// them from multiple threads at the same time. However, you can have multiple
-// stb_vorbis* handles and decode from them independently in multiple thrads.
-
-
-/////////// MEMORY ALLOCATION
-
-// normally stb_vorbis uses malloc() to allocate memory at startup,
-// and alloca() to allocate temporary memory during a frame on the
-// stack. (Memory consumption will depend on the amount of setup
-// data in the file and how you set the compile flags for speed
-// vs. size. In my test files the maximal-size usage is ~150KB.)
-//
-// You can modify the wrapper functions in the source (stbv_setup_malloc,
-// stbv_setup_temp_malloc, temp_malloc) to change this behavior, or you
-// can use a simpler allocation model: you pass in a buffer from
-// which stb_vorbis will allocate _all_ its memory (including the
-// temp memory). "open" may fail with a VORBIS_outofmem if you
-// do not pass in enough data; there is no way to determine how
-// much you do need except to succeed (at which point you can
-// query get_info to find the exact amount required. yes I know
-// this is lame).
-//
-// If you pass in a non-NULL buffer of the type below, allocation
-// will occur from it as described above. Otherwise just pass NULL
-// to use malloc()/alloca()

-/////////// PUSHDATA API
-
-#ifndef STB_VORBIS_NO_PUSHDATA_API
-
-// this API allows you to get blocks of data from any source and hand
-// them to stb_vorbis. you have to buffer them; stb_vorbis will tell
-// you how much it used, and you have to give it the rest next time;
-// and stb_vorbis may not have enough data to work with and you will
-// need to give it the same data again PLUS more. Note that the Vorbis
-// specification does not bound the size of an individual frame.
-
-STBVDEF stb_vorbis *stb_vorbis_open_pushdata(
- const unsigned char * datablock, int datablock_length_in_bytes,

-// the first N bytes of the file--you're told if it's not enough, see below)
-// on success, returns an stb_vorbis *, does not set error, returns the amount of
-// data parsed/consumed on this call in *datablock_memory_consumed_in_bytes;
-// on failure, returns NULL on error and sets *error, does not change *datablock_memory_consumed
-// if returns NULL and *error is VORBIS_need_more_data, then the input block was
-// incomplete and you need to pass in a larger block from the start of the file
-
-STBVDEF int stb_vorbis_decode_frame_pushdata(
- stb_vorbis *f,
- const unsigned char *datablock, int datablock_length_in_bytes,
- int *channels, // place to write number of float * buffers
- float ***output, // place to write float ** array of float * buffers
- int *samples // place to write number of output samples
- );
-// decode a frame of audio sample data if possible from the passed-in data block
-//
-// return value: number of bytes we used from datablock
-//
-// possible cases:
-// 0 bytes used, 0 samples output (need more data)
-// N bytes used, 0 samples output (resynching the stream, keep going)
-// N bytes used, M samples output (one frame of data)
-// note that after opening a file, you will ALWAYS get one N-bytes,0-sample
-// frame, because Vorbis always "discards" the first frame.
-//
-// Note that on resynch, stb_vorbis will rarely consume all of the buffer,
-// instead only datablock_length_in_bytes-3 or less. This is because it wants
-// to avoid missing parts of a page header if they cross a datablock boundary,
-// without writing state-machiney code to record a partial detection.
-//
-// The number of channels returned are stored in *channels (which can be
-// NULL--it is always the same as the number of channels reported by
-// get_info). *output will contain an array of float* buffers, one per
-// channel. In other words, (*output)[0][0] contains the first sample from
-// the first channel, and (*output)[1][0] contains the first sample from
-// the second channel.
-
-STBVDEF void stb_vorbis_flush_pushdata(stb_vorbis *f);
-// inform stb_vorbis that your next datablock will not be contiguous with
-// previous ones (e.g. you've seeked in the data); future attempts to decode
-// frames will cause stb_vorbis to resynchronize (as noted above), and
-// once it sees a valid Ogg page (typically 4-8KB, as large as 64KB), it
-// will begin decoding the _next_ frame.
-//
-// if you want to seek using pushdata, you need to seek in your file, then
-// call stb_vorbis_flush_pushdata(), then start calling decoding, then once
-// decoding is returning you data, call stb_vorbis_get_sample_offset, and
-// if you don't like the result, seek your file again and repeat.

-// of callback to your code. (But if you don't support seeking, you may

-/**
- * cgltf - a single-file glTF 2.0 parser written in C99.
- *
- * Version: 1.10
- *
- * Website: https://github.com/jkuhlmann/cgltf
- *
- * Distributed under the MIT License, see notice at the end of this file.
- *
- * Building:
- * Include this file where you need the struct and function
- * declarations. Have exactly one source file where you define
- * `CGLTF_IMPLEMENTATION` before including this file to get the
- * function definitions.
- *
- * Reference:
- * `cgltf_result cgltf_parse(const cgltf_options*, const void*,
- * cgltf_size, cgltf_data**)` parses both glTF and GLB data. If
- * this function returns `cgltf_result_success`, you have to call
- * `cgltf_free()` on the created `cgltf_data*` variable.
- * Note that contents of external files for buffers and images are not
- * automatically loaded. You'll need to read these files yourself using
- * URIs in the `cgltf_data` structure.
- *
- * `cgltf_options` is the struct passed to `cgltf_parse()` to control
- * parts of the parsing process. You can use it to force the file type
- * and provide memory allocation as well as file operation callbacks.
- * Should be zero-initialized to trigger default behavior.
- *
- * `cgltf_data` is the struct allocated and filled by `cgltf_parse()`.
- * It generally mirrors the glTF format as described by the spec (see
- * https://github.com/KhronosGroup/glTF/tree/master/specification/2.0).
- *
- * `void cgltf_free(cgltf_data*)` frees the allocated `cgltf_data`
- * variable.
- *
- * `cgltf_result cgltf_load_buffers(const cgltf_options*, cgltf_data*,
- * const char* gltf_path)` can be optionally called to open and read buffer
- * files using the `FILE*` APIs. The `gltf_path` argument is the path to
- * the original glTF file, which allows the parser to resolve the path to
- * buffer files.
- *
- * `cgltf_result cgltf_load_buffer_base64(const cgltf_options* options,
- * cgltf_size size, const char* base64, void** out_data)` decodes
- * base64-encoded data content. Used internally by `cgltf_load_buffers()`.
- * This is useful when decoding data URIs in images.
- *
- * `cgltf_result cgltf_parse_file(const cgltf_options* options, const
- * char* path, cgltf_data** out_data)` can be used to open the given
- * file using `FILE*` APIs and parse the data using `cgltf_parse()`.
- *
- * `cgltf_result cgltf_validate(cgltf_data*)` can be used to do additional
- * checks to make sure the parsed glTF data is valid.
- *
- * `cgltf_node_transform_local` converts the translation / rotation / scale properties of a node
- * into a mat4.
- *
- * `cgltf_node_transform_world` calls `cgltf_node_transform_local` on every ancestor in order
- * to compute the root-to-node transformation.
- *
- * `cgltf_accessor_unpack_floats` reads in the data from an accessor, applies sparse data (if any),
- * and converts them to floating point. Assumes that `cgltf_load_buffers` has already been called.
- * By passing null for the output pointer, users can find out how many floats are required in the
- * output buffer.
- *
- * `cgltf_accessor_num_components` is a tiny utility that tells you the dimensionality of
- * a certain accessor type. This can be used before `cgltf_accessor_unpack_floats` to help allocate
- * the necessary amount of memory.
- *
- * `cgltf_accessor_read_float` reads a certain element from a non-sparse accessor and converts it to
- * floating point, assuming that `cgltf_load_buffers` has already been called. The passed-in element
- * size is the number of floats in the output buffer, which should be in the range [1, 16]. Returns
- * false if the passed-in element_size is too small, or if the accessor is sparse.
- *
- * `cgltf_accessor_read_uint` is similar to its floating-point counterpart, but limited to reading
- * vector types and does not support matrix types. The passed-in element size is the number of uints
- * in the output buffer, which should be in the range [1, 4]. Returns false if the passed-in
- * element_size is too small, or if the accessor is sparse.
- *
- * `cgltf_accessor_read_index` is similar to its floating-point counterpart, but it returns size_t
- * and only works with single-component data types.
- *
- * `cgltf_result cgltf_copy_extras_json(const cgltf_data*, const cgltf_extras*,
- * char* dest, cgltf_size* dest_size)` allows users to retrieve the "extras" data that
- * can be attached to many glTF objects (which can be arbitrary JSON data). The
- * `cgltf_extras` struct stores the offsets of the start and end of the extras JSON data
- * as it appears in the complete glTF JSON data. This function copies the extras data
- * into the provided buffer. If `dest` is NULL, the length of the data is written into
- * `dest_size`. You can then parse this data using your own JSON parser
- * or, if you've included the cgltf implementation using the integrated JSMN JSON parser.

-RELEASE NOTES - v0.12.0
-=======================
-Version 0.12.0 has breaking API changes including changes to the existing API and the removal of deprecated APIs.
-
-
-Improved Client-Defined Memory Allocation
------------------------------------------
-The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
-existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom
-allocation callbacks are specified.
-
-To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this:
-
- void* my_malloc(size_t sz, void* pUserData)
- {
- return malloc(sz);
- }
- void* my_realloc(void* p, size_t sz, void* pUserData)
- {
- return realloc(p, sz);
- }
- void my_free(void* p, void* pUserData)
- {
- free(p);
- }
-
- ...
-
- drflac_allocation_callbacks allocationCallbacks;
- allocationCallbacks.pUserData = &myData;
- allocationCallbacks.onMalloc = my_malloc;
- allocationCallbacks.onRealloc = my_realloc;
- allocationCallbacks.onFree = my_free;
- drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks);
-
-The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
-
-Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC,
-DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions.
-
-Every API that opens a drflac object now takes this extra parameter. These include the following:
-
- drflac_open()
- drflac_open_relaxed()
- drflac_open_with_metadata()
- drflac_open_with_metadata_relaxed()
- drflac_open_file()
- drflac_open_file_with_metadata()
- drflac_open_memory()
- drflac_open_memory_with_metadata()
- drflac_open_and_read_pcm_frames_s32()
- drflac_open_and_read_pcm_frames_s16()
- drflac_open_and_read_pcm_frames_f32()
- drflac_open_file_and_read_pcm_frames_s32()
- drflac_open_file_and_read_pcm_frames_s16()
- drflac_open_file_and_read_pcm_frames_f32()
- drflac_open_memory_and_read_pcm_frames_s32()
- drflac_open_memory_and_read_pcm_frames_s16()
- drflac_open_memory_and_read_pcm_frames_f32()
-
-
-
-Optimizations
--------------
-Seeking performance has been greatly improved. A new binary search based seeking algorithm has been introduced which significantly
-improves performance over the brute force method which was used when no seek table was present. Seek table based seeking also takes
-advantage of the new binary search seeking system to further improve performance there as well. Note that this depends on CRC which
-means it will be disabled when DR_FLAC_NO_CRC is used.
-
-The SSE4.1 pipeline has been cleaned up and optimized. You should see some improvements with decoding speed of 24-bit files in
-particular. 16-bit streams should also see some improvement.
-
-drflac_read_pcm_frames_s16() has been optimized. Previously this sat on top of drflac_read_pcm_frames_s32() and performed it's s32
-to s16 conversion in a second pass. This is now all done in a single pass. This includes SSE2 and ARM NEON optimized paths.
-
-A minor optimization has been implemented for drflac_read_pcm_frames_s32(). This will now use an SSE2 optimized pipeline for stereo
-channel reconstruction which is the last part of the decoding process.
-
-The ARM build has seen a few improvements. The CLZ (count leading zeroes) and REV (byte swap) instructions are now used when
-compiling with GCC and Clang which is achieved using inline assembly. The CLZ instruction requires ARM architecture version 5 at
-compile time and the REV instruction requires ARM architecture version 6.
-
-An ARM NEON optimized pipeline has been implemented. To enable this you'll need to add -mfpu=neon to the command line when compiling.
-
-
-Removed APIs
-------------
-The following APIs were deprecated in version 0.11.0 and have been completely removed in version 0.12.0:
-
- drflac_read_s32() -> drflac_read_pcm_frames_s32()
- drflac_read_s16() -> drflac_read_pcm_frames_s16()
- drflac_read_f32() -> drflac_read_pcm_frames_f32()
- drflac_seek_to_sample() -> drflac_seek_to_pcm_frame()
- drflac_open_and_decode_s32() -> drflac_open_and_read_pcm_frames_s32()
- drflac_open_and_decode_s16() -> drflac_open_and_read_pcm_frames_s16()
- drflac_open_and_decode_f32() -> drflac_open_and_read_pcm_frames_f32()
- drflac_open_and_decode_file_s32() -> drflac_open_file_and_read_pcm_frames_s32()
- drflac_open_and_decode_file_s16() -> drflac_open_file_and_read_pcm_frames_s16()
- drflac_open_and_decode_file_f32() -> drflac_open_file_and_read_pcm_frames_f32()
- drflac_open_and_decode_memory_s32() -> drflac_open_memory_and_read_pcm_frames_s32()
- drflac_open_and_decode_memory_s16() -> drflac_open_memory_and_read_pcm_frames_s16()
- drflac_open_and_decode_memory_f32() -> drflac_open_memroy_and_read_pcm_frames_f32()
-
-Prior versions of dr_flac operated on a per-sample basis whereas now it operates on PCM frames. The removed APIs all relate
-to the old per-sample APIs. You now need to use the "pcm_frame" versions.
-*/
-
-
-/*
-Introduction
-============
-dr_flac is a single file library. To use it, do something like the following in one .c file.
-
- ```c
- #define DR_FLAC_IMPLEMENTATION
- #include "dr_flac.h"
- ```
-
-You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following:
-
- ```c
- drflac* pFlac = drflac_open_file("MySong.flac", NULL);
- if (pFlac == NULL) {
- // Failed to open FLAC file
- }
-
- drflac_int32* pSamples = malloc(pFlac->totalPCMFrameCount * pFlac->channels * sizeof(drflac_int32));
- drflac_uint64 numberOfInterleavedSamplesActuallyRead = drflac_read_pcm_frames_s32(pFlac, pFlac->totalPCMFrameCount, pSamples);
- ```
-
-The drflac object represents the decoder. It is a transparent type so all the information you need, such as the number of channels and the bits per sample,
-should be directly accessible - just make sure you don't change their values. Samples are always output as interleaved signed 32-bit PCM. In the example above
-a native FLAC stream was opened, however dr_flac has seamless support for Ogg encapsulated FLAC streams as well.
-
-You do not need to decode the entire stream in one go - you just specify how many samples you'd like at any given time and the decoder will give you as many
-samples as it can, up to the amount requested. Later on when you need the next batch of samples, just call it again. Example:
-
- ```c
- while (drflac_read_pcm_frames_s32(pFlac, chunkSizeInPCMFrames, pChunkSamples) > 0) {
- do_something();
- }
- ```
-
-You can seek to a specific PCM frame with `drflac_seek_to_pcm_frame()`.
-
-If you just want to quickly decode an entire FLAC file in one go you can do something like this:
-
- ```c
- unsigned int channels;
- unsigned int sampleRate;
- drflac_uint64 totalPCMFrameCount;
- drflac_int32* pSampleData = drflac_open_file_and_read_pcm_frames_s32("MySong.flac", &channels, &sampleRate, &totalPCMFrameCount, NULL);
- if (pSampleData == NULL) {
- // Failed to open and decode FLAC file.
- }
-
- ...
-
- drflac_free(pSampleData, NULL);
- ```
-
-You can read samples as signed 16-bit integer and 32-bit floating-point PCM with the *_s16() and *_f32() family of APIs respectively, but note that these
-should be considered lossy.
-
-
-If you need access to metadata (album art, etc.), use `drflac_open_with_metadata()`, `drflac_open_file_with_metdata()` or `drflac_open_memory_with_metadata()`.
-The rationale for keeping these APIs separate is that they're slightly slower than the normal versions and also just a little bit harder to use. dr_flac
-reports metadata to the application through the use of a callback, and every metadata block is reported before `drflac_open_with_metdata()` returns.
-
-The main opening APIs (`drflac_open()`, etc.) will fail if the header is not present. The presents a problem in certain scenarios such as broadcast style
-streams or internet radio where the header may not be present because the user has started playback mid-stream. To handle this, use the relaxed APIs:
-
- `drflac_open_relaxed()`
- `drflac_open_with_metadata_relaxed()`
-
-It is not recommended to use these APIs for file based streams because a missing header would usually indicate a corrupt or perverse file. In addition, these
-APIs can take a long time to initialize because they may need to spend a lot of time finding the first frame.
-
-
-
-Build Options
-=============
-#define these options before including this file.
-
-#define DR_FLAC_NO_STDIO
- Disable `drflac_open_file()` and family.
-
-#define DR_FLAC_NO_OGG
- Disables support for Ogg/FLAC streams.
-
-#define DR_FLAC_BUFFER_SIZE <number>
- Defines the size of the internal buffer to store data from onRead(). This buffer is used to reduce the number of calls back to the client for more data.
- Larger values means more memory, but better performance. My tests show diminishing returns after about 4KB (which is the default). Consider reducing this if
- you have a very efficient implementation of onRead(), or increase it if it's very inefficient. Must be a multiple of 8.
-
-#define DR_FLAC_NO_CRC
- Disables CRC checks. This will offer a performance boost when CRC is unnecessary. This will disable binary search seeking. When seeking, the seek table will
- be used if available. Otherwise the seek will be performed using brute force.
-
-#define DR_FLAC_NO_SIMD
- Disables SIMD optimizations (SSE on x86/x64 architectures, NEON on ARM architectures). Use this if you are having compatibility issues with your compiler.
-
-
-
-Notes
-=====
-- dr_flac does not support changing the sample rate nor channel count mid stream.
-- dr_flac is not thread-safe, but its APIs can be called from any thread so long as you do your own synchronization.
-- When using Ogg encapsulation, a corrupted metadata block will result in `drflac_open_with_metadata()` and `drflac_open()` returning inconsistent samples due
- to differences in corrupted stream recorvery logic between the two APIs.

-
-This is the lowest level function for opening a FLAC stream. You can also use `drflac_open_file()` and `drflac_open_memory()` to open the stream from a file or
-from a block of memory respectively.
-
-The STREAMINFO block must be present for this to succeed. Use `drflac_open_relaxed()` to open a FLAC stream where the header may not be present.

-Use `drflac_open_with_metadata()` if you need access to metadata.

-
-This is slower than `drflac_open()`, so avoid this one if you don't need metadata. Internally, this will allocate and free memory on the heap for every
-metadata block except for STREAMINFO and PADDING blocks.
-
-The caller is notified of the metadata via the `onMeta` callback. All metadata blocks will be handled before the function returns. This callback takes a
-pointer to a `drflac_metadata` object which is a union containing the data of all relevant metadata blocks. Use the `type` member to discriminate against
-the different metadata types.
-
-The STREAMINFO block must be present for this to succeed. Use `drflac_open_with_metadata_relaxed()` to open a FLAC stream where the header may not be present.
-
-Note that this will behave inconsistently with `drflac_open()` if the stream is an Ogg encapsulated stream and a metadata block is corrupted. This is due to
-the way the Ogg stream recovers from corrupted pages. When `drflac_open_with_metadata()` is being used, the open routine will try to read the contents of the
-metadata block, whereas `drflac_open()` will simply seek past it (for the sake of efficiency). This inconsistency can result in different samples being
-returned depending on whether or not the stream is being opened with metadata.

- It's critical for competitive decoding performance that this function be highly optimal. With MSVC we can use the __lzcnt64() and __lzcnt() intrinsics
- to achieve good performance, however on GCC and Clang it's a little bit more annoying. The __builtin_clzl() and __builtin_clzll() intrinsics leave
- it undefined as to the return value when `x` is 0. We need this to be well defined as returning 32 or 64, depending on whether or not it's a 32- or
- 64-bit build. To work around this we would need to add a conditional to check for the x = 0 case, but this creates unnecessary inefficiency. To work
- around this problem I have written some inline assembly to emit the LZCNT (x86) or CLZ (ARM) instruction directly which removes the need to include
- the conditional. This has worked well in the past, but for some reason Clang's MSVC compatible driver, clang-cl, does not seem to be handling this
- in the same way as the normal Clang driver. It seems that `clang-cl` is just outputting the wrong results sometimes, maybe due to some register
- getting clobbered?
-
- I'm not sure if this is a bug with dr_flac's inlined assembly (most likely), a bug in `clang-cl` or just a misunderstanding on my part with inline
- assembly rules for `clang-cl`. If somebody can identify an error in dr_flac's inlined assembly I'm happy to get that fixed.
-
- Fortunately there is an easy workaround for this. Clang implements MSVC-specific intrinsics for compatibility. It also defines _MSC_VER for extra
- compatibility. We can therefore just check for _MSC_VER and use the MSVC intrinsic which, fortunately for us, Clang supports. It would still be nice
- to know how to fix the inlined assembly for correctness sake, however.

- There are two ways to find the sample and seek past irrelevant frames:

-
- Both of these options have their own pros and cons. Using the native FLAC decoder is slower because it needs to
- do a full decode of the frame. Using Ogg's framing system is faster, but more complicated and involves some code
- duplication for the decoding of frame headers.
-
- Another thing to consider is that using the Ogg framing system will perform direct seeking of the physical Ogg
- bitstream. This is important to consider because it means we cannot read data from the drflac_bs object using the
- standard drflac__*() APIs because that will read in extra data for its own internal caching which in turn breaks
- the positioning of the read pointer of the physical Ogg bitstream. Therefore, anything that would normally be read
- using the native FLAC decoding APIs, such as drflac__read_next_flac_frame_header(), need to be re-implemented so as to
- avoid the use of the drflac_bs object.
-
- Considering these issues, I have decided to use the slower native FLAC decoding method for the following reasons:
- 1) Seeking is already partially accelerated using Ogg's paging system in the code block above.
- 2) Seeking in an Ogg encapsulated FLAC stream is probably quite uncommon.
- 3) Simplicity.

-
-v0.12.0 - 2019-09-23
- - API CHANGE: Add support for user defined memory allocation routines. This system allows the program to specify their own memory allocation
- routines with a user data pointer for client-specific contextual data. This adds an extra parameter to the end of the following APIs:
- - drflac_open()
- - drflac_open_relaxed()
- - drflac_open_with_metadata()
- - drflac_open_with_metadata_relaxed()
- - drflac_open_file()
- - drflac_open_file_with_metadata()
- - drflac_open_memory()
- - drflac_open_memory_with_metadata()
- - drflac_open_and_read_pcm_frames_s32()
- - drflac_open_and_read_pcm_frames_s16()
- - drflac_open_and_read_pcm_frames_f32()
- - drflac_open_file_and_read_pcm_frames_s32()
- - drflac_open_file_and_read_pcm_frames_s16()
- - drflac_open_file_and_read_pcm_frames_f32()
- - drflac_open_memory_and_read_pcm_frames_s32()
- - drflac_open_memory_and_read_pcm_frames_s16()
- - drflac_open_memory_and_read_pcm_frames_f32()
- Set this extra parameter to NULL to use defaults which is the same as the previous behaviour. Setting this NULL will use
- DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE.
- - Remove deprecated APIs:
- - drflac_read_s32()
- - drflac_read_s16()
- - drflac_read_f32()
- - drflac_seek_to_sample()
- - drflac_open_and_decode_s32()
- - drflac_open_and_decode_s16()
- - drflac_open_and_decode_f32()
- - drflac_open_and_decode_file_s32()
- - drflac_open_and_decode_file_s16()
- - drflac_open_and_decode_file_f32()
- - drflac_open_and_decode_memory_s32()
- - drflac_open_and_decode_memory_s16()
- - drflac_open_and_decode_memory_f32()
- - Remove drflac.totalSampleCount which is now replaced with drflac.totalPCMFrameCount. You can emulate drflac.totalSampleCount
- by doing pFlac->totalPCMFrameCount*pFlac->channels.
- - Rename drflac.currentFrame to drflac.currentFLACFrame to remove ambiguity with PCM frames.
- - Fix errors when seeking to the end of a stream.
- - Optimizations to seeking.
- - SSE improvements and optimizations.
- - ARM NEON optimizations.
- - Optimizations to drflac_read_pcm_frames_s16().
- - Optimizations to drflac_read_pcm_frames_s32().
-
-v0.11.10 - 2019-06-26

- - Fix warnings.
-
-v0.11.7 - 2019-05-06
- - C89 fixes.
-
-v0.11.6 - 2019-05-05
- - Add support for C89.
- - Fix a compiler warning when CRC is disabled.
- - Change license to choice of public domain or MIT-0.

-v0.11.0 - 2018-12-16
- - API CHANGE: Deprecated drflac_read_s32(), drflac_read_s16() and drflac_read_f32() and replaced them with
- drflac_read_pcm_frames_s32(), drflac_read_pcm_frames_s16() and drflac_read_pcm_frames_f32(). The new APIs take
- and return PCM frame counts instead of sample counts. To upgrade you will need to change the input count by
- dividing it by the channel count, and then do the same with the return value.
- - API_CHANGE: Deprecated drflac_seek_to_sample() and replaced with drflac_seek_to_pcm_frame(). Same rules as
- the changes to drflac_read_*() apply.

-
-v0.6 - 2017-07-22

- never existed. Frames are checked against their sync code, the CRC-8 of the frame header and the CRC-16 of the whole frame.
-
-v0.5 - 2017-07-16
- - Fix typos.
- - Change drflac_bool* types to unsigned.
- - Add CRC checking. This makes dr_flac slower, but can be disabled with #define DR_FLAC_NO_CRC.

-
-/*
-RELEASE NOTES - VERSION 0.6
-===========================
-Version 0.6 includes breaking changes with the configuration of decoders. The ability to customize the number of output channels and the sample rate has been
-removed. You must now use the channel count and sample rate reported by the MP3 stream itself, and all channel and sample rate conversion must be done
-yourself.
-
-
-Changes to Initialization
--------------------------
-Previously, `drmp3_init()`, etc. took a pointer to a `drmp3_config` object that allowed you to customize the output channels and sample rate. This has been
-removed. If you need the old behaviour you will need to convert the data yourself or just not upgrade. The following APIs have changed.
-
- `drmp3_init()`
- `drmp3_init_memory()`
- `drmp3_init_file()`
-
-
-Miscellaneous Changes
----------------------
-Support for loading a file from a `wchar_t` string has been added via the `drmp3_init_file_w()` API.
-*/
-
-/*
-Introducation
-=============
-dr_mp3 is a single file library. To use it, do something like the following in one .c file.
-
- ```c
- #define DR_MP3_IMPLEMENTATION
- #include "dr_mp3.h"
- ```
-
-You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following:
-
- ```c
- drmp3 mp3;
- if (!drmp3_init_file(&mp3, "MySong.mp3", NULL)) {
- // Failed to open file
- }
-
- ...
-
- drmp3_uint64 framesRead = drmp3_read_pcm_frames_f32(pMP3, framesToRead, pFrames);
- ```
-
-The drmp3 object is transparent so you can get access to the channel count and sample rate like so:
-
- ```
- drmp3_uint32 channels = mp3.channels;
- drmp3_uint32 sampleRate = mp3.sampleRate;
- ```
-
-The example above initializes a decoder from a file, but you can also initialize it from a block of memory and read and seek callbacks with
-`drmp3_init_memory()` and `drmp3_init()` respectively.
-
-You do not need to do any annoying memory management when reading PCM frames - this is all managed internally. You can request any number of PCM frames in each
-call to `drmp3_read_pcm_frames_f32()` and it will return as many PCM frames as it can, up to the requested amount.
-
-You can also decode an entire file in one go with `drmp3_open_and_read_pcm_frames_f32()`, `drmp3_open_memory_and_read_pcm_frames_f32()` and
-`drmp3_open_file_and_read_pcm_frames_f32()`.
-
-
-Build Options
-=============
-#define these options before including this file.
-
-#define DR_MP3_NO_STDIO
- Disable drmp3_init_file(), etc.
-
-#define DR_MP3_NO_SIMD
- Disable SIMD optimizations.

-DIFFERENCES BETWEEN minimp3 AND dr_mp3
-======================================
-- First, keep in mind that minimp3 (https://github.com/lieff/minimp3) is where all the real work was done. All of the
- code relating to the actual decoding remains mostly unmodified, apart from some namespacing changes.
-- dr_mp3 adds a pulling style API which allows you to deliver raw data via callbacks. So, rather than pushing data
- to the decoder, the decoder _pulls_ data from your callbacks.
-- In addition to callbacks, a decoder can be initialized from a block of memory and a file.
-- The dr_mp3 pull API reads PCM frames rather than whole MP3 frames.
-- dr_mp3 adds convenience APIs for opening and decoding entire files in one go.
-- dr_mp3 is fully namespaced, including the implementation section, which is more suitable when compiling projects
- as a single translation unit (aka unity builds). At the time of writing this, a unity build is not possible when
- using minimp3 in conjunction with stb_vorbis. dr_mp3 addresses this.
-*/
-
-/*
-RELEASE NOTES - v0.5.0
-=======================
-Version 0.5.0 has breaking API changes.
-
-Improved Client-Defined Memory Allocation
------------------------------------------
-The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
-existing system of DRMP3_MALLOC, DRMP3_REALLOC and DRMP3_FREE are still in place and will be used by default when no custom
-allocation callbacks are specified.
-
-To use the new system, you pass in a pointer to a drmp3_allocation_callbacks object to drmp3_init() and family, like this:
-
- void* my_malloc(size_t sz, void* pUserData)
- {
- return malloc(sz);
- }
- void* my_realloc(void* p, size_t sz, void* pUserData)
- {
- return realloc(p, sz);
- }
- void my_free(void* p, void* pUserData)
- {
- free(p);
- }
-
- ...
-
- drmp3_allocation_callbacks allocationCallbacks;
- allocationCallbacks.pUserData = &myData;
- allocationCallbacks.onMalloc = my_malloc;
- allocationCallbacks.onRealloc = my_realloc;
- allocationCallbacks.onFree = my_free;
- drmp3_init_file(&mp3, "my_file.mp3", NULL, &allocationCallbacks);
-
-The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
-
-Passing in null for the allocation callbacks object will cause dr_mp3 to use defaults which is the same as DRMP3_MALLOC,
-DRMP3_REALLOC and DRMP3_FREE and the equivalent of how it worked in previous versions.
-
-Every API that opens a drmp3 object now takes this extra parameter. These include the following:
-
- drmp3_init()
- drmp3_init_file()
- drmp3_init_memory()
- drmp3_open_and_read_pcm_frames_f32()
- drmp3_open_and_read_pcm_frames_s16()
- drmp3_open_memory_and_read_pcm_frames_f32()
- drmp3_open_memory_and_read_pcm_frames_s16()
- drmp3_open_file_and_read_pcm_frames_f32()
- drmp3_open_file_and_read_pcm_frames_s16()
-
-Renamed APIs
-------------
-The following APIs have been renamed for consistency with other dr_* libraries and to make it clear that they return PCM frame
-counts rather than sample counts.
-
- drmp3_open_and_read_f32() -> drmp3_open_and_read_pcm_frames_f32()
- drmp3_open_and_read_s16() -> drmp3_open_and_read_pcm_frames_s16()
- drmp3_open_memory_and_read_f32() -> drmp3_open_memory_and_read_pcm_frames_f32()
- drmp3_open_memory_and_read_s16() -> drmp3_open_memory_and_read_pcm_frames_s16()
- drmp3_open_file_and_read_f32() -> drmp3_open_file_and_read_pcm_frames_f32()
- drmp3_open_file_and_read_s16() -> drmp3_open_file_and_read_pcm_frames_s16()

-RELEASE NOTES - VERSION 0.12
-============================
-Version 0.12 includes breaking changes to custom chunk handling.
-
-
-Changes to Chunk Callback
--------------------------
-dr_wav supports the ability to fire a callback when a chunk is encounted (except for WAVE and FMT chunks). The callback has been updated to include both the
-container (RIFF or Wave64) and the FMT chunk which contains information about the format of the data in the wave file.
-
-Previously, there was no direct way to determine the container, and therefore no way to discriminate against the different IDs in the chunk header (RIFF and
-Wave64 containers encode chunk ID's differently). The `container` parameter can be used to know which ID to use.
-
-Sometimes it can be useful to know the data format at the time the chunk callback is fired. A pointer to a `drwav_fmt` object is now passed into the chunk
-callback which will give you information about the data format. To determine the sample format, use `drwav_fmt_get_format()`. This will return one of the
-`DR_WAVE_FORMAT_*` tokens.
-*/
-
-/*
-Introduction
-============
-This is a single file library. To use it, do something like the following in one .c file.
-
- ```c
- #define DR_WAV_IMPLEMENTATION
- #include "dr_wav.h"
- ```
-
-You can then #include this file in other parts of the program as you would with any other header file. Do something like the following to read audio data:
-
- ```c
- drwav wav;
- if (!drwav_init_file(&wav, "my_song.wav", NULL)) {
- // Error opening WAV file.
- }
-
- drwav_int32* pDecodedInterleavedPCMFrames = malloc(wav.totalPCMFrameCount * wav.channels * sizeof(drwav_int32));
- size_t numberOfSamplesActuallyDecoded = drwav_read_pcm_frames_s32(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames);
-
- ...
-
- drwav_uninit(&wav);
- ```
-
-If you just want to quickly open and read the audio data in a single operation you can do something like this:
-
- ```c
- unsigned int channels;
- unsigned int sampleRate;
- drwav_uint64 totalPCMFrameCount;
- float* pSampleData = drwav_open_file_and_read_pcm_frames_f32("my_song.wav", &channels, &sampleRate, &totalPCMFrameCount, NULL);
- if (pSampleData == NULL) {
- // Error opening and reading WAV file.
- }
-
- ...
-
- drwav_free(pSampleData, NULL);
- ```
-
-The examples above use versions of the API that convert the audio data to a consistent format (32-bit signed PCM, in this case), but you can still output the
-audio data in its internal format (see notes below for supported formats):
-
- ```c
- size_t framesRead = drwav_read_pcm_frames(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames);
- ```
-
-You can also read the raw bytes of audio data, which could be useful if dr_wav does not have native support for a particular data format:
-
- ```c
- size_t bytesRead = drwav_read_raw(&wav, bytesToRead, pRawDataBuffer);
- ```
-
-dr_wav can also be used to output WAV files. This does not currently support compressed formats. To use this, look at `drwav_init_write()`,
-`drwav_init_file_write()`, etc. Use `drwav_write_pcm_frames()` to write samples, or `drwav_write_raw()` to write raw data in the "data" chunk.
-
- ```c
- drwav_data_format format;
- format.container = drwav_container_riff; // <-- drwav_container_riff = normal WAV files, drwav_container_w64 = Sony Wave64.
- format.format = DR_WAVE_FORMAT_PCM; // <-- Any of the DR_WAVE_FORMAT_* codes.
- format.channels = 2;
- format.sampleRate = 44100;
- format.bitsPerSample = 16;
- drwav_init_file_write(&wav, "data/recording.wav", &format, NULL);
-
- ...
-
- drwav_uint64 framesWritten = drwav_write_pcm_frames(pWav, frameCount, pSamples);
- ```
-
-dr_wav has seamless support the Sony Wave64 format. The decoder will automatically detect it and it should Just Work without any manual intervention.
-
-
-Build Options
-=============
-#define these options before including this file.
-
-#define DR_WAV_NO_CONVERSION_API
- Disables conversion APIs such as `drwav_read_pcm_frames_f32()` and `drwav_s16_to_f32()`.
-
-#define DR_WAV_NO_STDIO
- Disables APIs that initialize a decoder from a file such as `drwav_init_file()`, `drwav_init_file_write()`, etc.
-
-
-
-Notes
-=====
-- Samples are always interleaved.
-- The default read function does not do any data conversion. Use `drwav_read_pcm_frames_f32()`, `drwav_read_pcm_frames_s32()` and `drwav_read_pcm_frames_s16()`
- to read and convert audio data to 32-bit floating point, signed 32-bit integer and signed 16-bit integer samples respectively. Tested and supported internal
- formats include the following:
- - Unsigned 8-bit PCM
- - Signed 12-bit PCM
- - Signed 16-bit PCM
- - Signed 24-bit PCM
- - Signed 32-bit PCM
- - IEEE 32-bit floating point
- - IEEE 64-bit floating point
- - A-law and u-law
- - Microsoft ADPCM
- - IMA ADPCM (DVI, format code 0x11)
-- dr_wav will try to read the WAV file as best it can, even if it's not strictly conformant to the WAV format.

-RELEASE NOTES - v0.11.0
-=======================
-Version 0.11.0 has breaking API changes.
-
-Improved Client-Defined Memory Allocation
------------------------------------------
-The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
-existing system of DRWAV_MALLOC, DRWAV_REALLOC and DRWAV_FREE are still in place and will be used by default when no custom
-allocation callbacks are specified.
-
-To use the new system, you pass in a pointer to a drwav_allocation_callbacks object to drwav_init() and family, like this:
-
- void* my_malloc(size_t sz, void* pUserData)
- {
- return malloc(sz);
- }
- void* my_realloc(void* p, size_t sz, void* pUserData)
- {
- return realloc(p, sz);
- }
- void my_free(void* p, void* pUserData)
- {
- free(p);
- }
-
- ...
-
- drwav_allocation_callbacks allocationCallbacks;
- allocationCallbacks.pUserData = &myData;
- allocationCallbacks.onMalloc = my_malloc;
- allocationCallbacks.onRealloc = my_realloc;
- allocationCallbacks.onFree = my_free;
- drwav_init_file(&wav, "my_file.wav", &allocationCallbacks);
-
-The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
-
-Passing in null for the allocation callbacks object will cause dr_wav to use defaults which is the same as DRWAV_MALLOC,
-DRWAV_REALLOC and DRWAV_FREE and the equivalent of how it worked in previous versions.
-
-Every API that opens a drwav object now takes this extra parameter. These include the following:
-
- drwav_init()
- drwav_init_ex()
- drwav_init_file()
- drwav_init_file_ex()
- drwav_init_file_w()
- drwav_init_file_w_ex()
- drwav_init_memory()
- drwav_init_memory_ex()
- drwav_init_write()
- drwav_init_write_sequential()
- drwav_init_write_sequential_pcm_frames()
- drwav_init_file_write()
- drwav_init_file_write_sequential()
- drwav_init_file_write_sequential_pcm_frames()
- drwav_init_file_write_w()
- drwav_init_file_write_sequential_w()
- drwav_init_file_write_sequential_pcm_frames_w()
- drwav_init_memory_write()
- drwav_init_memory_write_sequential()
- drwav_init_memory_write_sequential_pcm_frames()
- drwav_open_and_read_pcm_frames_s16()
- drwav_open_and_read_pcm_frames_f32()
- drwav_open_and_read_pcm_frames_s32()
- drwav_open_file_and_read_pcm_frames_s16()
- drwav_open_file_and_read_pcm_frames_f32()
- drwav_open_file_and_read_pcm_frames_s32()
- drwav_open_file_and_read_pcm_frames_s16_w()
- drwav_open_file_and_read_pcm_frames_f32_w()
- drwav_open_file_and_read_pcm_frames_s32_w()
- drwav_open_memory_and_read_pcm_frames_s16()
- drwav_open_memory_and_read_pcm_frames_f32()
- drwav_open_memory_and_read_pcm_frames_s32()
-
-Endian Improvements
--------------------
-Previously, the following APIs returned little-endian audio data. These now return native-endian data. This improves compatibility
-on big-endian architectures.
-
- drwav_read_pcm_frames()
- drwav_read_pcm_frames_s16()
- drwav_read_pcm_frames_s32()
- drwav_read_pcm_frames_f32()
- drwav_open_and_read_pcm_frames_s16()
- drwav_open_and_read_pcm_frames_s32()
- drwav_open_and_read_pcm_frames_f32()
- drwav_open_file_and_read_pcm_frames_s16()
- drwav_open_file_and_read_pcm_frames_s32()
- drwav_open_file_and_read_pcm_frames_f32()
- drwav_open_file_and_read_pcm_frames_s16_w()
- drwav_open_file_and_read_pcm_frames_s32_w()
- drwav_open_file_and_read_pcm_frames_f32_w()
- drwav_open_memory_and_read_pcm_frames_s16()
- drwav_open_memory_and_read_pcm_frames_s32()
- drwav_open_memory_and_read_pcm_frames_f32()
-
-APIs have been added to give you explicit control over whether or not audio data is read or written in big- or little-endian byte
-order:
-
- drwav_read_pcm_frames_le()
- drwav_read_pcm_frames_be()
- drwav_read_pcm_frames_s16le()
- drwav_read_pcm_frames_s16be()
- drwav_read_pcm_frames_f32le()
- drwav_read_pcm_frames_f32be()
- drwav_read_pcm_frames_s32le()
- drwav_read_pcm_frames_s32be()
- drwav_write_pcm_frames_le()
- drwav_write_pcm_frames_be()
-
-Removed APIs
-------------
-The following APIs were deprecated in version 0.10.0 and have now been removed:
-
- drwav_open()
- drwav_open_ex()
- drwav_open_write()
- drwav_open_write_sequential()
- drwav_open_file()
- drwav_open_file_ex()
- drwav_open_file_write()
- drwav_open_file_write_sequential()
- drwav_open_memory()
- drwav_open_memory_ex()
- drwav_open_memory_write()
- drwav_open_memory_write_sequential()
- drwav_close()
-
-
-
-RELEASE NOTES - v0.10.0
-=======================
-Version 0.10.0 has breaking API changes. There are no significant bug fixes in this release, so if you are affected you do
-not need to upgrade.
-
-Removed APIs
-------------
-The following APIs were deprecated in version 0.9.0 and have been completely removed in version 0.10.0:
-
- drwav_read()
- drwav_read_s16()
- drwav_read_f32()
- drwav_read_s32()
- drwav_seek_to_sample()
- drwav_write()
- drwav_open_and_read_s16()
- drwav_open_and_read_f32()
- drwav_open_and_read_s32()
- drwav_open_file_and_read_s16()
- drwav_open_file_and_read_f32()
- drwav_open_file_and_read_s32()
- drwav_open_memory_and_read_s16()
- drwav_open_memory_and_read_f32()
- drwav_open_memory_and_read_s32()
- drwav::totalSampleCount
-
-See release notes for version 0.9.0 at the bottom of this file for replacement APIs.
-
-Deprecated APIs
----------------
-The following APIs have been deprecated. There is a confusing and completely arbitrary difference between drwav_init*() and
-drwav_open*(), where drwav_init*() initializes a pre-allocated drwav object, whereas drwav_open*() will first allocated a
-drwav object on the heap and then initialize it. drwav_open*() has been deprecated which means you must now use a pre-
-allocated drwav object with drwav_init*(). If you need the previous functionality, you can just do a malloc() followed by
-a called to one of the drwav_init*() APIs.
-
- drwav_open()
- drwav_open_ex()
- drwav_open_write()
- drwav_open_write_sequential()
- drwav_open_file()
- drwav_open_file_ex()
- drwav_open_file_write()
- drwav_open_file_write_sequential()
- drwav_open_memory()
- drwav_open_memory_ex()
- drwav_open_memory_write()
- drwav_open_memory_write_sequential()
- drwav_close()
-
-These APIs will be removed completely in a future version. The rationale for this change is to remove confusion between the
-two different ways to initialize a drwav object.

-## Introduction
-
-GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan
-application development. It provides a simple, platform-independent API for
-creating windows, contexts and surfaces, reading input, handling events, etc.
-
-GLFW natively supports Windows, macOS and Linux and other Unix-like systems. On
-Linux both X11 and Wayland are supported.
-
-GLFW is licensed under the [zlib/libpng
-license](http://www.glfw.org/license.html).
-
-You can [download](http://www.glfw.org/download.html) the latest stable release
-as source or Windows binaries, or fetch the `latest` branch from GitHub. Each
-release starting with 3.0 also has a corresponding [annotated
-tag](https://github.com/glfw/glfw/releases) with source and binary archives.
-
-The [documentation](http://www.glfw.org/docs/latest/) is available online and is
-included in all source and binary archives. See the [release
-notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and
-deprecations in the latest release. For more details see the [version
-history](http://www.glfw.org/changelog.html).
-
-The `master` branch is the stable integration branch and _should_ always compile
-and run on all supported platforms, although details of newly added features may
-change until they have been included in a release. New features and many bug
-fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until
-they are stable enough to merge.
-
-If you are new to GLFW, you may find the
-[tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful. If
-you have used GLFW 2 in the past, there is a [transition
-guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW
-3 API.
-
-
-## Compiling GLFW
-
-GLFW itself requires only the headers and libraries for your OS and window
-system. It does not need the headers for any context creation API (WGL, GLX,
-EGL, NSGL, OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable
-support for them.
-
-GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and
-MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
-and Clang. It will likely compile in other environments as well, but this is
-not regularly tested.
-
-There are [pre-compiled Windows binaries](http://www.glfw.org/download.html)
-available for all supported compilers.
-
-See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for
-more information about how to compile GLFW yourself.
-
-
-## Using GLFW
-
-See the [documentation](http://www.glfw.org/docs/latest/) for tutorials, guides
-and the API reference.
-
-
-## Contributing to GLFW
-
-See the [contribution
-guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
-more information.
-
-
-## System requirements
-
-GLFW supports Windows XP and later and macOS 10.8 and later. Linux and other
-Unix-like systems running the X Window System are supported even without
-a desktop environment or modern extensions, although some features require
-a running window or clipboard manager. The OSMesa backend requires Mesa 6.3.
-
-See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html)
-in the documentation for more information.
-
-
-## Dependencies
-
-GLFW itself needs only CMake 3.1 or later and the headers and libraries for your
-OS and window system.
-
-The examples and test programs depend on a number of tiny libraries. These are
-located in the `deps/` directory.
-
- - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
- with command-line options
- - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
- examples
- - [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan
- functions
- - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
- examples
- - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI
- - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk
-
-The documentation is generated with [Doxygen](http://doxygen.org/) if CMake can
-find that tool.
-
-
-## Reporting bugs
-
-Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).
-Please check the [contribution
-guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
-information on what to include when reporting a bug.

- *
- * The master copy of khrplatform.h is maintained in the Khronos EGL
- * Registry repository at https://github.com/KhronosGroup/EGL-Registry
- * The last semantic modification to khrplatform.h was at commit ID:
- * 67a3e0864c2d75ea5287b9f3d2eb74a745936692
- *
- * Adopters may modify this file to suit their platform. Adopters are
- * encouraged to submit platform specific modifications to the Khronos
- * group so that they can be included in future versions of this file.
- * Please submit changes by filing pull requests or issues on
- * the EGL Registry repository linked above.
- *
- *
- * See the Implementer's Guidelines for information about where this file
- * should be located on your system and for more details of its use:
- * http://www.khronos.org/registry/implementers_guide.pdf
- *
- * This file should be included as
- * #include <KHR/khrplatform.h>
- * by Khronos client API header files that use its types and defines.
- *
- * The types in khrplatform.h should only be used to define API-specific types.
- *
- * Types defined in khrplatform.h:
- * khronos_int8_t signed 8 bit
- * khronos_uint8_t unsigned 8 bit
- * khronos_int16_t signed 16 bit
- * khronos_uint16_t unsigned 16 bit
- * khronos_int32_t signed 32 bit
- * khronos_uint32_t unsigned 32 bit
- * khronos_int64_t signed 64 bit
- * khronos_uint64_t unsigned 64 bit
- * khronos_intptr_t signed same number of bits as a pointer
- * khronos_uintptr_t unsigned same number of bits as a pointer
- * khronos_ssize_t signed size
- * khronos_usize_t unsigned size
- * khronos_float_t signed 32 bit floating point
- * khronos_time_ns_t unsigned 64 bit time in nanoseconds
- * khronos_utime_nanoseconds_t unsigned time interval or absolute time in
- * nanoseconds
- * khronos_stime_nanoseconds_t signed time interval in nanoseconds
- * khronos_boolean_enum_t enumerated boolean type. This should
- * only be used as a base type when a client API's boolean type is
- * an enum. Client APIs which use an integer or other type for
- * booleans cannot use this as the base type for their boolean.
- *
- * Tokens defined in khrplatform.h:
- *
- * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
- *
- * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
- * KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
- *
- * Calling convention macros defined in this file:
- * KHRONOS_APICALL
- * KHRONOS_APIENTRY
- * KHRONOS_APIATTRIBUTES
- *
- * These may be used in function prototypes as:

- *
- * This function creates a window and its associated OpenGL or OpenGL ES
- * context. Most of the options controlling how the window and its context
- * should be created are specified with [window hints](@ref window_hints).
- *
- * Successful creation does not change which context is current. Before you
- * can use the newly created context, you need to
- * [make it current](@ref context_current). For information about the `share`
- * parameter, see @ref context_sharing.
- *
- * The created window, framebuffer and context may differ from what you
- * requested, as not all parameters and hints are
- * [hard constraints](@ref window_hints_hard). This includes the size of the
- * window, especially for full screen windows. To query the actual attributes
- * of the created window, framebuffer and context, see @ref
- * glfwGetWindowAttrib, @ref glfwGetWindowSize and @ref glfwGetFramebufferSize.
- *
- * To create a full screen window, you need to specify the monitor the window
- * will cover. If no monitor is specified, the window will be windowed mode.
- * Unless you have a way for the user to choose a specific monitor, it is
- * recommended that you pick the primary monitor. For more information on how
- * to query connected monitors, see @ref monitor_monitors.
- *
- * For full screen windows, the specified size becomes the resolution of the
- * window's _desired video mode_. As long as a full screen window is not
- * iconified, the supported video mode most closely matching the desired video
- * mode is set for the specified monitor. For more information about full
- * screen windows, including the creation of so called _windowed full screen_
- * or _borderless full screen_ windows, see @ref window_windowed_full_screen.
- *
- * Once you have created the window, you can switch it between windowed and
- * full screen mode with @ref glfwSetWindowMonitor. This will not affect its
- * OpenGL or OpenGL ES context.
- *
- * By default, newly created windows use the placement recommended by the
- * window system. To create the window at a specific position, make it
- * initially invisible using the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window
- * hint, set its [position](@ref window_pos) and then [show](@ref window_hide)
- * it.
- *
- * As long as at least one full screen window is not iconified, the screensaver
- * is prohibited from starting.
- *
- * Window systems put limits on window sizes. Very large or very small window
- * dimensions may be overridden by the window system on creation. Check the
- * actual [size](@ref window_size) after creation.
- *
- * The [swap interval](@ref buffer_swap) is not set during window creation and
- * the initial value may vary depending on driver settings and defaults.
- *
- * @param[in] width The desired width, in screen coordinates, of the window.
- * This must be greater than zero.
- * @param[in] height The desired height, in screen coordinates, of the window.
- * This must be greater than zero.
- * @param[in] title The initial, UTF-8 encoded window title.
- * @param[in] monitor The monitor to use for full screen mode, or `NULL` for
- * windowed mode.
- * @param[in] share The window whose context to share resources with, or `NULL`
- * to not share resources.
- * @return The handle of the created window, or `NULL` if an

- *
- * @remark @win32 Window creation will fail if the Microsoft GDI software
- * OpenGL implementation is the only one available.
- *
- * @remark @win32 If the executable has an icon resource named `GLFW_ICON,` it
- * will be set as the initial icon for the window. If no such icon is present,
- * the `IDI_APPLICATION` icon will be used instead. To set a different icon,
- * see @ref glfwSetWindowIcon.
- *
- * @remark @win32 The context to share resources with must not be current on
- * any other thread.
- *
- * @remark @macos The OS only supports core profile contexts for OpenGL
- * versions 3.2 and later. Before creating an OpenGL context of version 3.2 or
- * later you must set the [GLFW_OPENGL_PROFILE](@ref GLFW_OPENGL_PROFILE_hint)
- * hint accordingly. OpenGL 3.0 and 3.1 contexts are not supported at all
- * on macOS.
- *
- * @remark @macos The GLFW window has no icon, as it is not a document
- * window, but the dock icon will be the same as the application bundle's icon.
- * For more information on bundles, see the
- * [Bundle Programming Guide](https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/)
- * in the Mac Developer Library.
- *
- * @remark @macos On OS X 10.10 and later the window frame will not be rendered
- * at full resolution on Retina displays unless the

- * in the Mac Developer Library. The GLFW test and example programs use
- * a custom `Info.plist` template for this, which can be found as
- * `CMake/Info.plist.in` in the source tree.
- *
- * @remark @macos When activating frame autosaving with
- * [GLFW_COCOA_FRAME_NAME](@ref GLFW_COCOA_FRAME_NAME_hint), the specified
- * window size and position may be overridden by previously saved values.
- *
- * @remark @x11 Some window managers will not respect the placement of
- * initially hidden windows.
- *
- * @remark @x11 Due to the asynchronous nature of X11, it may take a moment for
- * a window to reach its requested state. This means you may not be able to
- * query the final size, position or other attributes directly after window
- * creation.
- *
- * @remark @x11 The class part of the `WM_CLASS` window property will by
- * default be set to the window title passed to this function. The instance
- * part will use the contents of the `RESOURCE_NAME` environment variable, if
- * present and not empty, or fall back to the window title. Set the
- * [GLFW_X11_CLASS_NAME](@ref GLFW_X11_CLASS_NAME_hint) and
- * [GLFW_X11_INSTANCE_NAME](@ref GLFW_X11_INSTANCE_NAME_hint) window hints to
- * override this.
- *
- * @remark @wayland Compositors should implement the xdg-decoration protocol
- * for GLFW to decorate the window properly. If this protocol isn't
- * supported, or if the compositor prefers client-side decorations, a very
- * simple fallback frame will be drawn using the wp_viewporter protocol. A
- * compositor can still emit close, maximize or fullscreen events, using for
- * instance a keybind mechanism. If neither of these protocols is supported,
- * the window won't be decorated.
- *
- * @remark @wayland A full screen window will not attempt to change the mode,

- * Marcus: This code was originally written by Markus G. Kuhn.
- * I have made some slight changes (trimmed it down a bit from >60 KB to
- * 20 KB), but the functionality is the same.
- */
-
-/*
- * This module converts keysym values into the corresponding ISO 10646
- * (UCS, Unicode) values.
- *
- * The array keysymtab[] contains pairs of X11 keysym values for graphical
- * characters and the corresponding Unicode value. The function
- * _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
- * search, therefore keysymtab[] must remain SORTED by keysym value.
- *
- * We allow to represent any UCS character in the range U-00000000 to
- * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
- * This admittedly does not cover the entire 31-bit space of UCS, but
- * it does cover all of the characters up to U-10FFFF, which can be
- * represented by UTF-16, and more, and it is very unlikely that higher
- * UCS codes will ever be assigned by ISO. So to get Unicode character
- * U+ABCD you can directly use keysym 0x0100abcd.
- *
- * Original author: Markus G. Kuhn <mkuhn@acm.org>, University of
- * Cambridge, April 2001
- *
- * Special thanks to Richard Verhoeven <river@win.tue.nl> for preparing
- * an initial draft of the mapping table.

-1. Introduction
-===============
-miniaudio is a single file library for audio playback and capture. To use it, do the following in one .c file:
-
- ```c
- #define MINIAUDIO_IMPLEMENTATION
- #include "miniaudio.h"
- ```
-
-You can do `#include "miniaudio.h"` in other parts of the program just like any other header.
-
-miniaudio uses the concept of a "device" as the abstraction for physical devices. The idea is that you choose a physical device to emit or capture audio from,
-and then move data to/from the device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a callback which you specify when
-initializing the device.
-
-When initializing the device you first need to configure it. The device configuration allows you to specify things like the format of the data delivered via
-the callback, the size of the internal buffer and the ID of the device you want to emit or capture audio from.
-
-Once you have the device configuration set up you can initialize the device. When initializing a device you need to allocate memory for the device object
-beforehand. This gives the application complete control over how the memory is allocated. In the example below we initialize a playback device on the stack,
-but you could allocate it on the heap if that suits your situation better.
-
- ```c
- void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount)
- {
- // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both
- // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than
- // frameCount frames.
- }
-
- int main()
- {
- ma_device_config config = ma_device_config_init(ma_device_type_playback);
- config.playback.format = ma_format_f32; // Set to ma_format_unknown to use the device's native format.
- config.playback.channels = 2; // Set to 0 to use the device's native channel count.
- config.sampleRate = 48000; // Set to 0 to use the device's native sample rate.
- config.dataCallback = data_callback; // This function will be called when miniaudio needs more data.
- config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData).
-
- ma_device device;
- if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) {
- return -1; // Failed to initialize the device.
- }
-
- ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually.
-
- // Do something here. Probably your program's main loop.
-
- ma_device_uninit(&device); // This will stop the device so no need to do that manually.
- return 0;
- }
- ```
-
-In the example above, `data_callback()` is where audio data is written and read from the device. The idea is in playback mode you cause sound to be emitted
-from the speakers by writing audio data to the output buffer (`pOutput` in the example). In capture mode you read data from the input buffer (`pInput`) to
-extract sound captured by the microphone. The `frameCount` parameter tells you how many frames can be written to the output buffer and read from the input
-buffer. A "frame" is one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 samples: one for the left, one for the right.
-The channel count is defined by the device config. The size in bytes of an individual sample is defined by the sample format which is also specified in the
-device config. Multi-channel audio data is always interleaved, which means the samples for each frame are stored next to each other in memory. For example, in
-a stereo stream the first pair of samples will be the left and right samples for the first frame, the second pair of samples will be the left and right samples
-for the second frame, etc.
-
-The configuration of the device is defined by the `ma_device_config` structure. The config object is always initialized with `ma_device_config_init()`. It's
-important to always initialize the config with this function as it initializes it with logical defaults and ensures your program doesn't break when new members
-are added to the `ma_device_config` structure. The example above uses a fairly simple and standard device configuration. The call to `ma_device_config_init()`
-takes a single parameter, which is whether or not the device is a playback, capture, duplex or loopback device (loopback devices are not supported on all
-backends). The `config.playback.format` member sets the sample format which can be one of the following (all formats are native-endian):
-
- +---------------+----------------------------------------+---------------------------+
- | Symbol | Description | Range |
- +---------------+----------------------------------------+---------------------------+
- | ma_format_f32 | 32-bit floating point | [-1, 1] |
- | ma_format_s16 | 16-bit signed integer | [-32768, 32767] |
- | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] |
- | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] |
- | ma_format_u8 | 8-bit unsigned integer | [0, 255] |
- +---------------+----------------------------------------+---------------------------+
-
-The `config.playback.channels` member sets the number of channels to use with the device. The channel count cannot exceed MA_MAX_CHANNELS. The
-`config.sampleRate` member sets the sample rate (which must be the same for both playback and capture in full-duplex configurations). This is usually set to
-44100 or 48000, but can be set to anything. It's recommended to keep this between 8000 and 384000, however.
-
-Note that leaving the format, channel count and/or sample rate at their default values will result in the internal device's native configuration being used
-which is useful if you want to avoid the overhead of miniaudio's automatic data conversion.
-
-In addition to the sample format, channel count and sample rate, the data callback and user data pointer are also set via the config. The user data pointer is
-not passed into the callback as a parameter, but is instead set to the `pUserData` member of `ma_device` which you can access directly since all miniaudio
-structures are transparent.
-
-Initializing the device is done with `ma_device_init()`. This will return a result code telling you what went wrong, if anything. On success it will return
-`MA_SUCCESS`. After initialization is complete the device will be in a stopped state. To start it, use `ma_device_start()`. Uninitializing the device will stop
-it, which is what the example above does, but you can also stop the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again.
-Note that it's important to never stop or start the device from inside the callback. This will result in a deadlock. Instead you set a variable or signal an
-event indicating that the device needs to stop and handle it in a different thread. The following APIs must never be called inside the callback:
-
- ```c
- ma_device_init()
- ma_device_init_ex()
- ma_device_uninit()
- ma_device_start()
- ma_device_stop()
- ```
-
-You must never try uninitializing and reinitializing a device inside the callback. You must also never try to stop and start it from inside the callback. There
-are a few other things you shouldn't do in the callback depending on your requirements, however this isn't so much a thread-safety thing, but rather a
-real-time processing thing which is beyond the scope of this introduction.
-
-The example above demonstrates the initialization of a playback device, but it works exactly the same for capture. All you need to do is change the device type
-from `ma_device_type_playback` to `ma_device_type_capture` when setting up the config, like so:
-
- ```c
- ma_device_config config = ma_device_config_init(ma_device_type_capture);
- config.capture.format = MY_FORMAT;
- config.capture.channels = MY_CHANNEL_COUNT;
- ```
-
-In the data callback you just read from the input buffer (`pInput` in the example above) and leave the output buffer alone (it will be set to NULL when the
-device type is set to `ma_device_type_capture`).
-
-These are the available device types and how you should handle the buffers in the callback:
-
- +-------------------------+--------------------------------------------------------+
- | Device Type | Callback Behavior |
- +-------------------------+--------------------------------------------------------+
- | ma_device_type_playback | Write to output buffer, leave input buffer untouched. |
- | ma_device_type_capture | Read from input buffer, leave output buffer untouched. |
- | ma_device_type_duplex | Read from input buffer, write to output buffer. |
- | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. |
- +-------------------------+--------------------------------------------------------+
-
-You will notice in the example above that the sample format and channel count is specified separately for playback and capture. This is to support different
-data formats between the playback and capture devices in a full-duplex system. An example may be that you want to capture audio data as a monaural stream (one
-channel), but output sound to a stereo speaker system. Note that if you use different formats between playback and capture in a full-duplex configuration you
-will need to convert the data yourself. There are functions available to help you do this which will be explained later.
-
-The example above did not specify a physical device to connect to which means it will use the operating system's default device. If you have multiple physical
-devices connected and you want to use a specific one you will need to specify the device ID in the configuration, like so:
-
- ```c
- config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device.
- config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device.
- ```
-
-To retrieve the device ID you will need to perform device enumeration, however this requires the use of a new concept called the "context". Conceptually
-speaking the context sits above the device. There is one context to many devices. The purpose of the context is to represent the backend at a more global level
-and to perform operations outside the scope of an individual device. Mainly it is used for performing run-time linking against backend libraries, initializing
-backends and enumerating devices. The example below shows how to enumerate devices.
-
- ```c
- ma_context context;
- if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) {
- // Error.
- }
-
- ma_device_info* pPlaybackInfos;
- ma_uint32 playbackCount;
- ma_device_info* pCaptureInfos;
- ma_uint32 captureCount;
- if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) {
- // Error.
- }
-
- // Loop over each device info and do something with it. Here we just print the name with their index. You may want
- // to give the user the opportunity to choose which device they'd prefer.
- for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) {
- printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name);
- }
-
- ma_device_config config = ma_device_config_init(ma_device_type_playback);
- config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id;
- config.playback.format = MY_FORMAT;
- config.playback.channels = MY_CHANNEL_COUNT;
- config.sampleRate = MY_SAMPLE_RATE;
- config.dataCallback = data_callback;
- config.pUserData = pMyCustomData;
-
- ma_device device;
- if (ma_device_init(&context, &config, &device) != MA_SUCCESS) {
- // Error
- }
-
- ...
-
- ma_device_uninit(&device);
- ma_context_uninit(&context);
- ```
-
-The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. The first parameter is a pointer to a list of `ma_backend`
-values which are used to override the default backend priorities. When this is NULL, as in this example, miniaudio's default priorities are used. The second
-parameter is the number of backends listed in the array pointed to by the first parameter. The third parameter is a pointer to a `ma_context_config` object
-which can be NULL, in which case defaults are used. The context configuration is used for setting the logging callback, custom memory allocation callbacks,
-user-defined data and some backend-specific configurations.
-
-Once the context has been initialized you can enumerate devices. In the example above we use the simpler `ma_context_get_devices()`, however you can also use a
-callback for handling devices by using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer to a pointer that will,
-upon output, be set to a pointer to a buffer containing a list of `ma_device_info` structures. You also provide a pointer to an unsigned integer that will
-receive the number of items in the returned buffer. Do not free the returned buffers as their memory is managed internally by miniaudio.
-
-The `ma_device_info` structure contains an `id` member which is the ID you pass to the device config. It also contains the name of the device which is useful
-for presenting a list of devices to the user via the UI.
-
-When creating your own context you will want to pass it to `ma_device_init()` when initializing the device. Passing in NULL, like we do in the first example,
-will result in miniaudio creating the context for you, which you don't want to do since you've already created a context. Note that internally the context is
-only tracked by it's pointer which means you must not change the location of the `ma_context` object. If this is an issue, consider using `malloc()` to
-allocate memory for the context.
-
-
-
-2. Building
-===========
-miniaudio should work cleanly out of the box without the need to download or install any dependencies. See below for platform-specific details.
-
-
-2.1. Windows
-------------
-The Windows build should compile cleanly on all popular compilers without the need to configure any include paths nor link to any libraries.
-
-2.2. macOS and iOS
-------------------
-The macOS build should compile cleanly without the need to download any dependencies nor link to any libraries or frameworks. The iOS build needs to be
-compiled as Objective-C and will need to link the relevant frameworks but should compile cleanly out of the box with Xcode. Compiling through the command line
-requires linking to `-lpthread` and `-lm`.
-
-Due to the way miniaudio links to frameworks at runtime, your application may not pass Apple's notarization process. To fix this there are two options. The
-first is to use the `MA_NO_RUNTIME_LINKING` option, like so:
-
- ```c
- #ifdef __APPLE__
- #define MA_NO_RUNTIME_LINKING
- #endif
- #define MINIAUDIO_IMPLEMENTATION
- #include "miniaudio.h"
- ```
-
-This will require linking with `-framework CoreFoundation -framework CoreAudio -framework AudioUnit`. Alternatively, if you would rather keep using runtime
-linking you can add the following to your entitlements.xcent file:
-
- ```
- <key>com.apple.security.cs.allow-dyld-environment-variables</key>
- <true/>
- <key>com.apple.security.cs.allow-unsigned-executable-memory</key>
- <true/>
- ```
-
-
-2.3. Linux
-----------
-The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any development packages.
-
-2.4. BSD
---------
-The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses sndio and FreeBSD uses OSS.
-
-2.5. Android
-------------
-AAudio is the highest priority backend on Android. This should work out of the box without needing any kind of compiler configuration. Support for AAudio
-starts with Android 8 which means older versions will fall back to OpenSL|ES which requires API level 16+.
-
-There have been reports that the OpenSL|ES backend fails to initialize on some Android based devices due to `dlopen()` failing to open "libOpenSLES.so". If
-this happens on your platform you'll need to disable run-time linking with `MA_NO_RUNTIME_LINKING` and link with -lOpenSLES.
-
-2.6. Emscripten
----------------
-The Emscripten build emits Web Audio JavaScript directly and should compile cleanly out of the box. You cannot use -std=c* compiler flags, nor -ansi.
-
-
-2.7. Build Options
-------------------
-`#define` these options before including miniaudio.h.

-
-3. Definitions
-==============
-This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity in the use of terms throughout the audio space, so this
-section is intended to clarify how miniaudio uses each term.
-
-3.1. Sample
------------
-A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit floating point number.
-
-3.2. Frame / PCM Frame
-----------------------
-A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 samples, a mono frame is 1 sample, a 5.1 surround sound frame
-is 6 samples, etc. The terms "frame" and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. If ever miniaudio
-needs to refer to a compressed frame, such as a FLAC frame, it will always clarify what it's referring to with something like "FLAC frame".
-
-3.3. Channel
-------------
-A stream of monaural audio that is emitted from an individual speaker in a speaker system, or received from an individual microphone in a microphone system. A
-stereo stream has two channels (a left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio systems refer to a channel as
-a complex audio stream that's mixed with other channels to produce the final mix - this is completely different to miniaudio's use of the term "channel" and
-should not be confused.
-
-3.4. Sample Rate
-----------------
-The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number of PCM frames that are processed per second.
-
-3.5. Formats
-------------
-Throughout miniaudio you will see references to different sample formats:
-
- +---------------+----------------------------------------+---------------------------+
- | Symbol | Description | Range |
- +---------------+----------------------------------------+---------------------------+
- | ma_format_f32 | 32-bit floating point | [-1, 1] |
- | ma_format_s16 | 16-bit signed integer | [-32768, 32767] |
- | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] |
- | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] |
- | ma_format_u8 | 8-bit unsigned integer | [0, 255] |
- +---------------+----------------------------------------+---------------------------+
-
-All formats are native-endian.
-
-
-
-4. Decoding
-===========
-The `ma_decoder` API is used for reading audio files. Decoders are completely decoupled from devices and can be used independently. The following formats are
-supported:
-
- +---------+------------------+----------+
- | Format | Decoding Backend | Built-In |
- +---------+------------------+----------+
- | WAV | dr_wav | Yes |
- | MP3 | dr_mp3 | Yes |
- | FLAC | dr_flac | Yes |
- | Vorbis | stb_vorbis | No |
- +---------+------------------+----------+
-
-Vorbis is supported via stb_vorbis which can be enabled by including the header section before the implementation of miniaudio, like the following:
-
- ```c
- #define STB_VORBIS_HEADER_ONLY
- #include "extras/stb_vorbis.c" // Enables Vorbis decoding.
-
- #define MINIAUDIO_IMPLEMENTATION
- #include "miniaudio.h"
-
- // The stb_vorbis implementation must come after the implementation of miniaudio.
- #undef STB_VORBIS_HEADER_ONLY
- #include "extras/stb_vorbis.c"
- ```
-
-A copy of stb_vorbis is included in the "extras" folder in the miniaudio repository (https://github.com/mackron/miniaudio).
-
-Built-in decoders are amalgamated into the implementation section of miniaudio. You can disable the built-in decoders by specifying one or more of the
-following options before the miniaudio implementation:
-
- ```c
- #define MA_NO_WAV
- #define MA_NO_MP3
- #define MA_NO_FLAC
- ```
-
-Disabling built-in decoding libraries is useful if you use these libraries independantly of the `ma_decoder` API.
-
-A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with `ma_decoder_init_memory()`, or from data delivered via callbacks
-with `ma_decoder_init()`. Here is an example for loading a decoder from a file:
-
- ```c
- ma_decoder decoder;
- ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder);
- if (result != MA_SUCCESS) {
- return false; // An error occurred.
- }
-
- ...
-
- ma_decoder_uninit(&decoder);
- ```
-
-When initializing a decoder, you can optionally pass in a pointer to a `ma_decoder_config` object (the `NULL` argument in the example above) which allows you
-to configure the output format, channel count, sample rate and channel map:
-
- ```c
- ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000);
- ```
-
-When passing in `NULL` for decoder config in `ma_decoder_init*()`, the output format will be the same as that defined by the decoding backend.
-
-Data is read from the decoder as PCM frames. This will return the number of PCM frames actually read. If the return value is less than the requested number of
-PCM frames it means you've reached the end:
-
- ```c
- ma_uint64 framesRead = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead);
- if (framesRead < framesToRead) {
- // Reached the end.
- }
- ```
-
-You can also seek to a specific frame like so:
-
- ```c
- ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame);
- if (result != MA_SUCCESS) {
- return false; // An error occurred.
- }
- ```
-
-If you want to loop back to the start, you can simply seek back to the first PCM frame:
-
- ```c
- ma_decoder_seek_to_pcm_frame(pDecoder, 0);
- ```
-
-When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding backend. This can be unnecessarily inefficient if the type
-is already known. In this case you can use the `_wav`, `_mp3`, etc. varients of the aforementioned initialization APIs:
-
- ```c
- ma_decoder_init_wav()
- ma_decoder_init_mp3()
- ma_decoder_init_memory_wav()
- ma_decoder_init_memory_mp3()
- ma_decoder_init_file_wav()
- ma_decoder_init_file_mp3()
- etc.
- ```
-
-The `ma_decoder_init_file()` API will try using the file extension to determine which decoding backend to prefer.
-
-
-
-5. Encoding
-===========
-The `ma_encoding` API is used for writing audio files. The only supported output format is WAV which is achieved via dr_wav which is amalgamated into the
-implementation section of miniaudio. This can be disabled by specifying the following option before the implementation of miniaudio:
-
- ```c
- #define MA_NO_WAV
- ```
-
-An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data delivered via callbacks with `ma_encoder_init()`. Below is an
-example for initializing an encoder to output to a file.
-
- ```c
- ma_encoder_config config = ma_encoder_config_init(ma_resource_format_wav, FORMAT, CHANNELS, SAMPLE_RATE);
- ma_encoder encoder;
- ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder);
- if (result != MA_SUCCESS) {
- // Error
- }
-
- ...
-
- ma_encoder_uninit(&encoder);
- ```
-
-When initializing an encoder you must specify a config which is initialized with `ma_encoder_config_init()`. Here you must specify the file type, the output
-sample format, output channel count and output sample rate. The following file types are supported:
-
- +------------------------+-------------+
- | Enum | Description |
- +------------------------+-------------+
- | ma_resource_format_wav | WAV |
- +------------------------+-------------+
-
-If the format, channel count or sample rate is not supported by the output file type an error will be returned. The encoder will not perform data conversion so
-you will need to convert it before outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the example below:
-
- ```c
- framesWritten = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite);
- ```
-
-Encoders must be uninitialized with `ma_encoder_uninit()`.
-
-
-6. Data Conversion
-==================
-A data conversion API is included with miniaudio which supports the majority of data conversion requirements. This supports conversion between sample formats,
-channel counts (with channel mapping) and sample rates.
-
-
-6.1. Sample Format Conversion
------------------------------
-Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and `ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()`
-to convert between two specific formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use `ma_convert_pcm_frames_format()` to convert
-PCM frames where you want to specify the frame count and channel count as a variable instead of the total sample count.
-
-
-6.1.1. Dithering
-----------------
-Dithering can be set using the ditherMode parameter.
-
-The different dithering modes include the following, in order of efficiency:
-
- +-----------+--------------------------+
- | Type | Enum Token |
- +-----------+--------------------------+
- | None | ma_dither_mode_none |
- | Rectangle | ma_dither_mode_rectangle |
- | Triangle | ma_dither_mode_triangle |
- +-----------+--------------------------+
-
-Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be ignored for conversions where dithering is not needed.
-Dithering is available for the following conversions:
-
- ```
- s16 -> u8
- s24 -> u8
- s32 -> u8
- f32 -> u8
- s24 -> s16
- s32 -> s16
- f32 -> s16
- ```
-
-Note that it is not an error to pass something other than ma_dither_mode_none for conversions where dither is not used. It will just be ignored.
-
-
-
-6.2. Channel Conversion
------------------------
-Channel conversion is used for channel rearrangement and conversion from one channel count to another. The `ma_channel_converter` API is used for channel
-conversion. Below is an example of initializing a simple channel converter which converts from mono to stereo.
-
- ```c
- ma_channel_converter_config config = ma_channel_converter_config_init(
- ma_format, // Sample format
- 1, // Input channels
- NULL, // Input channel map
- 2, // Output channels
- NULL, // Output channel map
- ma_channel_mix_mode_default); // The mixing algorithm to use when combining channels.
-
- result = ma_channel_converter_init(&config, &converter);
- if (result != MA_SUCCESS) {
- // Error.
- }
- ```
-
-To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so:
-
- ```c
- ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount);
- if (result != MA_SUCCESS) {
- // Error.
- }
- ```
-
-It is up to the caller to ensure the output buffer is large enough to accomodate the new PCM frames.
-
-Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported.
-
-
-6.2.1. Channel Mapping
-----------------------
-In addition to converting from one channel count to another, like the example above, the channel converter can also be used to rearrange channels. When
-initializing the channel converter, you can optionally pass in channel maps for both the input and output frames. If the channel counts are the same, and each
-channel map contains the same channel positions with the exception that they're in a different order, a simple shuffling of the channels will be performed. If,
-however, there is not a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed based on a mixing mode which is
-specified when initializing the `ma_channel_converter_config` object.
-
-When converting from mono to multi-channel, the mono channel is simply copied to each output channel. When going the other way around, the audio of each output
-channel is simply averaged and copied to the mono channel.
-
-In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess channels and silence extra channels. For example, converting
-from 4 to 2 channels, the 3rd and 4th channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and 4th channels.
-
-The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a simple distribution between input and output. Imagine sitting
-in the middle of a room, with speakers on the walls representing channel positions. The MA_CHANNEL_FRONT_LEFT position can be thought of as being in the corner
-of the front and left walls.
-
-Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined weights. Custom weights can be passed in as the last parameter of
-`ma_channel_converter_config_init()`.
-
-Predefined channel maps can be retrieved with `ma_get_standard_channel_map()`. This takes a `ma_standard_channel_map` enum as it's first parameter, which can
-be one of the following:
-
- +-----------------------------------+-----------------------------------------------------------+
- | Name | Description |
- +-----------------------------------+-----------------------------------------------------------+
- | ma_standard_channel_map_default | Default channel map used by miniaudio. See below. |
- | ma_standard_channel_map_microsoft | Channel map used by Microsoft's bitfield channel maps. |
- | ma_standard_channel_map_alsa | Default ALSA channel map. |

- | ma_standard_channel_map_webaudio | https://webaudio.github.io/web-audio-api/#ChannelOrdering |
- +-----------------------------------+-----------------------------------------------------------+
-
-Below are the channel maps used by default in miniaudio (`ma_standard_channel_map_default`):
-
- +---------------+---------------------------------+
- | Channel Count | Mapping |
- +---------------+---------------------------------+
- | 1 (Mono) | 0: MA_CHANNEL_MONO |
- +---------------+---------------------------------+
- | 2 (Stereo) | 0: MA_CHANNEL_FRONT_LEFT <br> |

- | | mapping as the device. |
- +---------------+---------------------------------+
-
-
-
-6.3. Resampling
----------------
-Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something like the following:
-
- ```c
- ma_resampler_config config = ma_resampler_config_init(
- ma_format_s16,
- channels,
- sampleRateIn,
- sampleRateOut,
- ma_resample_algorithm_linear);
-
- ma_resampler resampler;
- ma_result result = ma_resampler_init(&config, &resampler);
- if (result != MA_SUCCESS) {
- // An error occurred...
- }
- ```
-
-Do the following to uninitialize the resampler:
-
- ```c
- ma_resampler_uninit(&resampler);
- ```
-
-The following example shows how data can be processed
-
- ```c
- ma_uint64 frameCountIn = 1000;
- ma_uint64 frameCountOut = 2000;
- ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
- if (result != MA_SUCCESS) {
- // An error occurred...
- }
-
- // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the
- // number of output frames written.
- ```
-
-To initialize the resampler you first need to set up a config (`ma_resampler_config`) with `ma_resampler_config_init()`. You need to specify the sample format
-you want to use, the number of channels, the input and output sample rate, and the algorithm.
-
-The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format you will need to perform pre- and post-conversions yourself
-where necessary. Note that the format is the same for both input and output. The format cannot be changed after initialization.
-
-The resampler supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
-
-The sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the
-only configuration property that can be changed after initialization.
-
-The miniaudio resampler supports multiple algorithms:
-
- +-----------+------------------------------+
- | Algorithm | Enum Token |
- +-----------+------------------------------+
- | Linear | ma_resample_algorithm_linear |
- | Speex | ma_resample_algorithm_speex |
- +-----------+------------------------------+
-
-Because Speex is not public domain it is strictly opt-in and the code is stored in separate files. if you opt-in to the Speex backend you will need to consider
-it's license, the text of which can be found in it's source files in "extras/speex_resampler". Details on how to opt-in to the Speex resampler is explained in
-the Speex Resampler section below.
-
-The algorithm cannot be changed after initialization.
-
-Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
-frames, use `ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number of
-input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
-number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
-buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
-
-The sample rate can be changed dynamically on the fly. You can change this with explicit sample rates with `ma_resampler_set_rate()` and also with a decimal
-ratio with `ma_resampler_set_rate_ratio()`. The ratio is in/out.
-
-Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
-`ma_resampler_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
-input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`.
-
-Due to the nature of how resampling works, the resampler introduces some latency. This can be retrieved in terms of both the input rate and the output rate
-with `ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`.
-
-
-6.3.1. Resampling Algorithms
-----------------------------
-The choice of resampling algorithm depends on your situation and requirements. The linear resampler is the most efficient and has the least amount of latency,
-but at the expense of poorer quality. The Speex resampler is higher quality, but slower with more latency. It also performs several heap allocations internally
-for memory management.
-
-
-6.3.1.1. Linear Resampling
---------------------------
-The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, some control over the quality of the linear resampler which
-may make it a suitable option depending on your requirements.
-
-The linear resampler performs low-pass filtering before or after downsampling or upsampling, depending on the sample rates you're converting between. When
-decreasing the sample rate, the low-pass filter will be applied before downsampling. When increasing the rate it will be performed after upsampling. By default
-a fourth order low-pass filter will be applied. This can be configured via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering.
-
-The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of the input and output sample rates (Nyquist Frequency). This
-can be controlled with the `lpfNyquistFactor` config variable. This defaults to 1, and should be in the range of 0..1, although a value of 0 does not make
-sense and should be avoided. A value of 1 will use the Nyquist Frequency as the cutoff. A value of 0.5 will use half the Nyquist Frequency as the cutoff, etc.
-Values less than 1 will result in more washed out sound due to more of the higher frequencies being removed. This config variable has no impact on performance
-and is a purely perceptual configuration.
-
-The API for the linear resampler is the same as the main resampler API, only it's called `ma_linear_resampler`.
-
-
-6.3.1.2. Speex Resampling
--------------------------
-The Speex resampler is made up of third party code which is released under the BSD license. Because it is licensed differently to miniaudio, which is public
-domain, it is strictly opt-in and all of it's code is stored in separate files. If you opt-in to the Speex resampler you must consider the license text in it's
-source files. To opt-in, you must first `#include` the following file before the implementation of miniaudio.h:
-
- ```c
- #include "extras/speex_resampler/ma_speex_resampler.h"
- ```
-
-Both the header and implementation is contained within the same file. The implementation can be included in your program like so:
-
- ```c
- #define MINIAUDIO_SPEEX_RESAMPLER_IMPLEMENTATION
- #include "extras/speex_resampler/ma_speex_resampler.h"
- ```
-
-Note that even if you opt-in to the Speex backend, miniaudio won't use it unless you explicitly ask for it in the respective config of the object you are
-initializing. If you try to use the Speex resampler without opting in, initialization of the `ma_resampler` object will fail with `MA_NO_BACKEND`.
-
-The only configuration option to consider with the Speex resampler is the `speex.quality` config variable. This is a value between 0 and 10, with 0 being
-the fastest with the poorest quality and 10 being the slowest with the highest quality. The default value is 3.
-
-
-
-6.4. General Data Conversion
-----------------------------
-The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and resampling into one operation. This is what miniaudio uses
-internally to convert between the format requested when the device was initialized and the format of the backend's native device. The API for general data
-conversion is very similar to the resampling API. Create a `ma_data_converter` object like this:
-
- ```c
- ma_data_converter_config config = ma_data_converter_config_init(
- inputFormat,
- outputFormat,
- inputChannels,
- outputChannels,
- inputSampleRate,
- outputSampleRate
- );
-
- ma_data_converter converter;
- ma_result result = ma_data_converter_init(&config, &converter);
- if (result != MA_SUCCESS) {
- // An error occurred...
- }
- ```
-
-In the example above we use `ma_data_converter_config_init()` to initialize the config, however there's many more properties that can be configured, such as
-channel maps and resampling quality. Something like the following may be more suitable depending on your requirements:
-
- ```c
- ma_data_converter_config config = ma_data_converter_config_init_default();
- config.formatIn = inputFormat;
- config.formatOut = outputFormat;
- config.channelsIn = inputChannels;
- config.channelsOut = outputChannels;
- config.sampleRateIn = inputSampleRate;
- config.sampleRateOut = outputSampleRate;
- ma_get_standard_channel_map(ma_standard_channel_map_flac, config.channelCountIn, config.channelMapIn);
- config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER;
- ```
-
-Do the following to uninitialize the data converter:
-
- ```c
- ma_data_converter_uninit(&converter);
- ```
-
-The following example shows how data can be processed
-
- ```c
- ma_uint64 frameCountIn = 1000;
- ma_uint64 frameCountOut = 2000;
- ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
- if (result != MA_SUCCESS) {
- // An error occurred...
- }
-
- // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number
- // of output frames written.
- ```
-
-The data converter supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
-
-Sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the only
-configuration property that can be changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of `ma_data_converter_config` is
-set to `MA_TRUE`. To change the sample rate, use `ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. The
-resampling algorithm cannot be changed after initialization.
-
-Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
-frames, use `ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number
-of input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
-number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
-buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
-
-Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
-`ma_data_converter_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
-input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`.
-
-Due to the nature of how resampling works, the data converter introduces some latency if resampling is required. This can be retrieved in terms of both the
-input rate and the output rate with `ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`.
-
-
-
-7. Filtering
-============
-
-7.1. Biquad Filtering
----------------------
-Biquad filtering is achieved with the `ma_biquad` API. Example:
-
- ```c
- ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2);
- ma_result result = ma_biquad_init(&config, &biquad);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount);
- ```
-
-Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, b1 and b2, and the denominator coefficients are a0, a1 and
-a2. The a0 coefficient is required and coefficients must not be pre-normalized.
-
-Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. When using
-`ma_format_s16` the biquad filter will use fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used.
-
-Input and output frames are always interleaved.
-
-Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
-
- ```c
- ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount);
- ```
-
-If you need to change the values of the coefficients, but maintain the values in the registers you can do so with `ma_biquad_reinit()`. This is useful if you
-need to change the properties of the filter while keeping the values of registers valid to avoid glitching. Do not use `ma_biquad_init()` for this as it will
-do a full initialization which involves clearing the registers to 0. Note that changing the format or channel count after initialization is invalid and will
-result in an error.
-
-
-7.2. Low-Pass Filtering
------------------------
-Low-pass filtering is achieved with the following APIs:
-
- +---------+------------------------------------------+
- | API | Description |
- +---------+------------------------------------------+
- | ma_lpf1 | First order low-pass filter |
- | ma_lpf2 | Second order low-pass filter |
- | ma_lpf | High order low-pass filter (Butterworth) |
- +---------+------------------------------------------+
-
-Low-pass filter example:
-
- ```c
- ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order);
- ma_result result = ma_lpf_init(&config, &lpf);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount);
- ```
-
-Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. Input and output
-frames are always interleaved.
-
-Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
-
- ```c
- ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount);
- ```
-
-The maximum filter order is limited to `MA_MAX_FILTER_ORDER` which is set to 8. If you need more, you can chain first and second order filters together.
-
- ```c
- for (iFilter = 0; iFilter < filterCount; iFilter += 1) {
- ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount);
- }
- ```
-
-If you need to change the configuration of the filter, but need to maintain the state of internal registers you can do so with `ma_lpf_reinit()`. This may be
-useful if you need to change the sample rate and/or cutoff frequency dynamically while maintaing smooth transitions. Note that changing the format or channel
-count after initialization is invalid and will result in an error.
-
-The `ma_lpf` object supports a configurable order, but if you only need a first order filter you may want to consider using `ma_lpf1`. Likewise, if you only
-need a second order filter you can use `ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient.
-
-If an even filter order is specified, a series of second order filters will be processed in a chain. If an odd filter order is specified, a first order filter
-will be applied, followed by a series of second order filters in a chain.
-
-
-7.3. High-Pass Filtering
-------------------------
-High-pass filtering is achieved with the following APIs:
-
- +---------+-------------------------------------------+
- | API | Description |
- +---------+-------------------------------------------+
- | ma_hpf1 | First order high-pass filter |
- | ma_hpf2 | Second order high-pass filter |
- | ma_hpf | High order high-pass filter (Butterworth) |
- +---------+-------------------------------------------+
-
-High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, `ma_hpf2` and `ma_hpf`. See example code for low-pass filters
-for example usage.
-
-
-7.4. Band-Pass Filtering
-------------------------
-Band-pass filtering is achieved with the following APIs:
-
- +---------+-------------------------------+
- | API | Description |
- +---------+-------------------------------+
- | ma_bpf2 | Second order band-pass filter |
- | ma_bpf | High order band-pass filter |
- +---------+-------------------------------+
-
-Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and `ma_hpf`. See example code for low-pass filters for example
-usage. Note that the order for band-pass filters must be an even number which means there is no first order band-pass filter, unlike low-pass and high-pass
-filters.
-
-
-7.5. Notch Filtering
---------------------
-Notch filtering is achieved with the following APIs:
-
- +-----------+------------------------------------------+
- | API | Description |
- +-----------+------------------------------------------+
- | ma_notch2 | Second order notching filter |
- +-----------+------------------------------------------+
-
-
-7.6. Peaking EQ Filtering
--------------------------
-Peaking filtering is achieved with the following APIs:
-
- +----------+------------------------------------------+
- | API | Description |
- +----------+------------------------------------------+
- | ma_peak2 | Second order peaking filter |
- +----------+------------------------------------------+
-
-
-7.7. Low Shelf Filtering
-------------------------
-Low shelf filtering is achieved with the following APIs:
-
- +-------------+------------------------------------------+
- | API | Description |
- +-------------+------------------------------------------+
- | ma_loshelf2 | Second order low shelf filter |
- +-------------+------------------------------------------+
-
-Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to just turn them down rather than eliminate them entirely.
-
-
-7.8. High Shelf Filtering
--------------------------
-High shelf filtering is achieved with the following APIs:
-
- +-------------+------------------------------------------+
- | API | Description |
- +-------------+------------------------------------------+
- | ma_hishelf2 | Second order high shelf filter |
- +-------------+------------------------------------------+
-
-The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` instead of `ma_loshelf`. Where a low shelf filter is used to
-adjust the volume of low frequencies, the high shelf filter does the same thing for high frequencies.
-
-
-
-
-8. Waveform and Noise Generation
-================================
-
-8.1. Waveforms
---------------
-miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved with the `ma_waveform` API. Example:
-
- ```c
- ma_waveform_config config = ma_waveform_config_init(
- FORMAT,
- CHANNELS,
- SAMPLE_RATE,
- ma_waveform_type_sine,
- amplitude,
- frequency);
-
- ma_waveform waveform;
- ma_result result = ma_waveform_init(&config, &waveform);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount);
- ```
-
-The amplitude, frequency, type, and sample rate can be changed dynamically with `ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()`,
-`ma_waveform_set_type()`, and `ma_waveform_set_sample_rate()` respectively.
-
-You can invert the waveform by setting the amplitude to a negative value. You can use this to control whether or not a sawtooth has a positive or negative
-ramp, for example.
-
-Below are the supported waveform types:
-
- +---------------------------+
- | Enum Name |
- +---------------------------+
- | ma_waveform_type_sine |
- | ma_waveform_type_square |
- | ma_waveform_type_triangle |
- | ma_waveform_type_sawtooth |
- +---------------------------+
-
-
-
-8.2. Noise
-----------
-miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example:
-
- ```c
- ma_noise_config config = ma_noise_config_init(
- FORMAT,
- CHANNELS,
- ma_noise_type_white,
- SEED,
- amplitude);
-
- ma_noise noise;
- ma_result result = ma_noise_init(&config, &noise);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_noise_read_pcm_frames(&noise, pOutput, frameCount);
- ```
-
-The noise API uses simple LCG random number generation. It supports a custom seed which is useful for things like automated testing requiring reproducibility.
-Setting the seed to zero will default to `MA_DEFAULT_LCG_SEED`.
-
-The amplitude, seed, and type can be changed dynamically with `ma_noise_set_amplitude()`, `ma_noise_set_seed()`, and `ma_noise_set_type()` respectively.
-
-By default, the noise API will use different values for different channels. So, for example, the left side in a stereo stream will be different to the right
-side. To instead have each channel use the same random value, set the `duplicateChannels` member of the noise config to true, like so:
-
- ```c
- config.duplicateChannels = MA_TRUE;
- ```
-
-Below are the supported noise types.
-
- +------------------------+
- | Enum Name |
- +------------------------+
- | ma_noise_type_white |
- | ma_noise_type_pink |
- | ma_noise_type_brownian |
- +------------------------+
-
-
-
-9. Audio Buffers
-================
-miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can read from memory that's managed by the application, but
-can also handle the memory management for you internally. Memory management is flexible and should support most use cases.
-
-Audio buffers are initialised using the standard configuration system used everywhere in miniaudio:
-
- ```c
- ma_audio_buffer_config config = ma_audio_buffer_config_init(
- format,
- channels,
- sizeInFrames,
- pExistingData,
- &allocationCallbacks);
-
- ma_audio_buffer buffer;
- result = ma_audio_buffer_init(&config, &buffer);
- if (result != MA_SUCCESS) {
- // Error.
- }
-
- ...
-
- ma_audio_buffer_uninit(&buffer);
- ```
-
-In the example above, the memory pointed to by `pExistingData` will *not* be copied and is how an application can do self-managed memory allocation. If you
-would rather make a copy of the data, use `ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`.
-
-Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure and the raw audio data in a contiguous block of memory. That is,
-the raw audio data will be located immediately after the `ma_audio_buffer` structure. To do this, use `ma_audio_buffer_alloc_and_init()`:
-
- ```c
- ma_audio_buffer_config config = ma_audio_buffer_config_init(
- format,
- channels,
- sizeInFrames,
- pExistingData,
- &allocationCallbacks);
-
- ma_audio_buffer* pBuffer
- result = ma_audio_buffer_alloc_and_init(&config, &pBuffer);
- if (result != MA_SUCCESS) {
- // Error
- }
-
- ...
-
- ma_audio_buffer_uninit_and_free(&buffer);
- ```
-
-If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it with `ma_audio_buffer_uninit_and_free()`. In the example above,
-the memory pointed to by `pExistingData` will be copied into the buffer, which is contrary to the behavior of `ma_audio_buffer_init()`.
-
-An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the cursor moves forward. The last parameter (`loop`) can be
-used to determine if the buffer should loop. The return value is the number of frames actually read. If this is less than the number of frames requested it
-means the end has been reached. This should never happen if the `loop` parameter is set to true. If you want to manually loop back to the start, you can do so
-with with `ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an audio buffer.
-
- ```c
- ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping);
- if (framesRead < desiredFrameCount) {
- // If not looping, this means the end has been reached. This should never happen in looping mode with valid input.
- }
- ```
-
-Sometimes you may want to avoid the cost of data movement between the internal buffer and the output buffer. Instead you can use memory mapping to retrieve a
-pointer to a segment of data:
-
- ```c
- void* pMappedFrames;
- ma_uint64 frameCount = frameCountToTryMapping;
- ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount);
- if (result == MA_SUCCESS) {
- // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be
- // less due to the end of the buffer being reached.
- ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels);
-
- // You must unmap the buffer.
- ma_audio_buffer_unmap(pAudioBuffer, frameCount);
- }
- ```
-
-When you use memory mapping, the read cursor is increment by the frame count passed in to `ma_audio_buffer_unmap()`. If you decide not to process every frame
-you can pass in a value smaller than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is that it does not handle looping
-for you. You can determine if the buffer is at the end for the purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of
-`ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` as an error when returned by `ma_audio_buffer_unmap()`.
-
-
-
-10. Ring Buffers
-================
-miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates
-on bytes, whereas the `ma_pcm_rb` operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around `ma_rb`.
-
-Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved streams. The caller can also allocate their own backing memory for
-the ring buffer to use internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for you.
-
-The examples below use the PCM frame variant of the ring buffer since that's most likely the one you will want to use. To initialize a ring buffer, do
-something like the following:
-
- ```c
- ma_pcm_rb rb;
- ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb);
- if (result != MA_SUCCESS) {
- // Error
- }
- ```
-
-The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because it's the PCM varient of the ring buffer API. For the regular
-ring buffer that operates on bytes you would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes instead of frames. The
-fourth parameter is an optional pre-allocated buffer and the fifth parameter is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation
-routines. Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used.
-
-Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is offset from each other based on the stride. To manage your
-sub-buffers you can use `ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and `ma_pcm_rb_get_subbuffer_ptr()`.
-
-Use `ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section of the ring buffer. You specify the number of frames you
-need, and on output it will set to what was actually acquired. If the read or write pointer is positioned such that the number of frames requested will require
-a loop, it will be clamped to the end of the buffer. Therefore, the number of frames you're given may be less than the number you requested.
-
-After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the buffer and then "commit" it with `ma_pcm_rb_commit_read()` or
-`ma_pcm_rb_commit_write()`. This is where the read/write pointers are updated. When you commit you need to pass in the buffer that was returned by the earlier
-call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and
-`ma_pcm_rb_commit_write()` is what's used to increment the pointers, and can be less that what was originally requested.
-
-If you want to correct for drift between the write pointer and the read pointer you can use a combination of `ma_pcm_rb_pointer_distance()`,
-`ma_pcm_rb_seek_read()` and `ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only move the read pointer forward via
-the consumer thread, and the write pointer forward by the producer thread. If there is too much space between the pointers, move the read pointer forward. If
-there is too little space between the pointers, move the write pointer forward.
-
-You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` API. This is exactly the same, only you will use the `ma_rb`
-functions instead of `ma_pcm_rb` and instead of frame counts you will pass around byte counts.
-
-The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most significant bit being used to encode a loop flag and the internally
-managed buffers always being aligned to MA_SIMD_ALIGNMENT.
-
-Note that the ring buffer is only thread safe when used by a single consumer thread and single producer thread.
-

-11. Backends
-============
-The following backends are supported by miniaudio.
-
- +-------------+-----------------------+--------------------------------------------------------+
- | Name | Enum Name | Supported Operating Systems |
- +-------------+-----------------------+--------------------------------------------------------+
- | WASAPI | ma_backend_wasapi | Windows Vista+ |
- | DirectSound | ma_backend_dsound | Windows XP+ |
- | WinMM | ma_backend_winmm | Windows XP+ (may work on older versions, but untested) |
- | Core Audio | ma_backend_coreaudio | macOS, iOS |
- | ALSA | ma_backend_alsa | Linux |
- | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) |
- | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) |
- | sndio | ma_backend_sndio | OpenBSD |
- | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD |
- | OSS | ma_backend_oss | FreeBSD |
- | AAudio | ma_backend_aaudio | Android 8+ |
- | OpenSL ES | ma_backend_opensl | Android (API level 16+) |
- | Web Audio | ma_backend_webaudio | Web (via Emscripten) |
- | Custom | ma_backend_custom | Cross Platform |
- | Null | ma_backend_null | Cross Platform (not used on Web) |
- +-------------+-----------------------+--------------------------------------------------------+
-
-Some backends have some nuance details you may want to be aware of.
-
-11.1. WASAPI
-------------
-- Low-latency shared mode will be disabled when using an application-defined sample rate which is different to the device's native sample rate. To work around
- this, set `wasapi.noAutoConvertSRC` to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing when the
- `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC will result in miniaudio's internal resampler being used instead
- which will in turn enable the use of low-latency shared mode.
-
-11.2. PulseAudio
-----------------
-- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki:
- https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. Alternatively, consider using a different backend such as ALSA.
-
-11.3. Android
--------------
-- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: `<uses-permission android:name="android.permission.RECORD_AUDIO" />`
-- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a limitation with OpenSL|ES.
-- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration API (devices are enumerated through Java). You can however
- perform your own device enumeration through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it to ma_device_init().
-- The backend API will perform resampling where possible. The reason for this as opposed to using miniaudio's built-in resampler is to take advantage of any
- potential device-specific optimizations the driver may implement.
-
-11.4. UWP
----------
-- UWP only supports default playback and capture devices.
-- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest):
-
- ```
- <Package ...>
- ...
- <Capabilities>
- <DeviceCapability Name="microphone" />
- </Capabilities>
- </Package>
- ```
-
-11.5. Web Audio / Emscripten
-----------------------------
-- You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build.
-- The first time a context is initialized it will create a global object called "miniaudio" whose primary purpose is to act as a factory for device objects.
-- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as they've been deprecated.
-- Google has implemented a policy in their browsers that prevent automatic media output without first receiving some kind of user input. The following web page
- has additional details: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device may fail if you try to start playback
- without first handling some kind of user input.
-
-
-
-12. Miscellaneous Notes
-=======================
-- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for WASAPI and Core Audio, however other backends such as
- PulseAudio may naturally support it, though not all have been tested.
-- The contents of the output buffer passed into the data callback will always be pre-initialized to silence unless the `noPreZeroedOutputBuffer` config variable
- in `ma_device_config` is set to true, in which case it'll be undefined which will require you to write something to the entire buffer.
-- By default miniaudio will automatically clip samples. This only applies when the playback sample format is configured as `ma_format_f32`. If you are doing
- clipping yourself, you can disable this overhead by setting `noClip` to true in the device config.
-- The sndio backend is currently only enabled on OpenBSD builds.
-- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can use it.
-- Note that GCC and Clang requires `-msse2`, `-mavx2`, etc. for SIMD optimizations.
-- When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This is due to 64-bit file APIs not being available.

-Logging Levels
-==============
-A log level will automatically include the lower levels. For example, verbose logging will enable everything. The warning log level will only include warnings
-and errors, but will ignore informational and verbose logging. If you only want to handle a specific log level, implement a custom log callback (see
-ma_context_init() for details) and interrogate the `logLevel` parameter.
-
-By default the log level will be set to MA_LOG_LEVEL_ERROR, but you can change this by defining MA_LOG_LEVEL before the implementation of miniaudio.
-
-MA_LOG_LEVEL_VERBOSE
- Mainly intended for debugging. This will enable all log levels and can be triggered from within the data callback so care must be taken when enabling this
- in production environments.
-
-MA_LOG_LEVEL_INFO
- Informational logging. Useful for debugging. This will also enable warning and error logs. This will never be called from within the data callback.
-
-MA_LOG_LEVEL_WARNING
- Warnings. You should enable this in you development builds and action them when encounted. This will also enable error logs. These logs usually indicate a
- potential problem or misconfiguration, but still allow you to keep running. This will never be called from within the data callback.
-
-MA_LOG_LEVEL_ERROR
- Error logging. This will be fired when an operation fails and is subsequently aborted. This can be fired from within the data callback, in which case the
- device will be stopped. You should always have this log level enabled.

-The callback for processing audio data from the device.
-
-The data callback is fired by miniaudio whenever the device needs to have more data delivered to a playback device, or when a capture device has some data
-available. This is called as soon as the backend asks for more data which means it may be called with inconsistent frame counts. You cannot assume the
-callback will be fired with a consistent frame count.
-
-
-Parameters
-----------
-pDevice (in)
- A pointer to the relevant device.
-
-pOutput (out)
- A pointer to the output buffer that will receive audio data that will later be played back through the speakers. This will be non-null for a playback or
- full-duplex device and null for a capture and loopback device.
-
-pInput (in)
- A pointer to the buffer containing input data from a recording device. This will be non-null for a capture, full-duplex or loopback device and null for a
- playback device.
-
-frameCount (in)
- The number of PCM frames to process. Note that this will not necessarily be equal to what you requested when you initialized the device. The
- `periodSizeInFrames` and `periodSizeInMilliseconds` members of the device config are just hints, and are not necessarily exactly what you'll get. You must
- not assume this will always be the same value each time the callback is fired.
-
-
-Remarks
--------
-You cannot stop and start the device from inside the callback or else you'll get a deadlock. You must also not uninitialize the device from inside the
-callback. The following APIs cannot be called from inside the callback:
-
- ma_device_init()
- ma_device_init_ex()
- ma_device_uninit()
- ma_device_start()
- ma_device_stop()
-
-The proper way to stop the device is to call `ma_device_stop()` from a different thread, normally the main application thread.

-/*
-These are the callbacks required to be implemented for a backend. These callbacks are grouped into two parts: context and device. There is one context
-to many devices. A device is created from a context.
-
-The general flow goes like this:
-
- 1) A context is created with `onContextInit()`
- 1a) Available devices can be enumerated with `onContextEnumerateDevices()` if required.
- 1b) Detailed information about a device can be queried with `onContextGetDeviceInfo()` if required.
- 2) A device is created from the context that was created in the first step using `onDeviceInit()`, and optionally a device ID that was
- selected from device enumeration via `onContextEnumerateDevices()`.
- 3) A device is started or stopped with `onDeviceStart()` / `onDeviceStop()`
- 4) Data is delivered to and from the device by the backend. This is always done based on the native format returned by the prior call
- to `onDeviceInit()`. Conversion between the device's native format and the format requested by the application will be handled by
- miniaudio internally.
-
-Initialization of the context is quite simple. You need to do any necessary initialization of internal objects and then output the
-callbacks defined in this structure.
-
-Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which
-physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the
-given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration
-needs to stop and the `onContextEnumerateDevices()` function return with a success code.
-
-Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID,
-and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the
-case when the device ID is NULL, in which case information about the default device needs to be retrieved.
-
-Once the context has been created and the device ID retrieved (if using anything other than the default device), the device can be created.
-This is a little bit more complicated than initialization of the context due to it's more complicated configuration. When initializing a
-device, a duplex device may be requested. This means a separate data format needs to be specified for both playback and capture. On input,
-the data format is set to what the application wants. On output it's set to the native format which should match as closely as possible to
-the requested format. The conversion between the format requested by the application and the device's native format will be handled
-internally by miniaudio.
-
-On input, if the sample format is set to `ma_format_unknown`, the backend is free to use whatever sample format it desires, so long as it's
-supported by miniaudio. When the channel count is set to 0, the backend should use the device's native channel count. The same applies for
-sample rate. For the channel map, the default should be used when `ma_channel_map_blank()` returns true (all channels set to
-`MA_CHANNEL_NONE`). On input, the `periodSizeInFrames` or `periodSizeInMilliseconds` option should always be set. The backend should
-inspect both of these variables. If `periodSizeInFrames` is set, it should take priority, otherwise it needs to be derived from the period
-size in milliseconds (`periodSizeInMilliseconds`) and the sample rate, keeping in mind that the sample rate may be 0, in which case the
-sample rate will need to be determined before calculating the period size in frames. On output, all members of the `ma_device_data_format`
-object should be set to a valid value, except for `periodSizeInMilliseconds` which is optional (`periodSizeInFrames` *must* be set).
-
-Starting and stopping of the device is done with `onDeviceStart()` and `onDeviceStop()` and should be self-explanatory. If the backend uses
-asynchronous reading and writing, `onDeviceStart()` and `onDeviceStop()` should always be implemented.
-
-The handling of data delivery between the application and the device is the most complicated part of the process. To make this a bit
-easier, some helper callbacks are available. If the backend uses a blocking read/write style of API, the `onDeviceRead()` and
-`onDeviceWrite()` callbacks can optionally be implemented. These are blocking and work just like reading and writing from a file. If the
-backend uses a callback for data delivery, that callback must call `ma_device_handle_backend_data_callback()` from within it's callback.
-This allows miniaudio to then process any necessary data conversion and then pass it to the miniaudio data callback.
-
-If the backend requires absolute flexibility with it's data delivery, it can optionally implement the `onDeviceWorkerThread()` callback
-which will allow it to implement the logic that will run on the audio thread. This is much more advanced and is completely optional.
-
-The audio thread should run data delivery logic in a loop while `ma_device_get_state() == MA_STATE_STARTED` and no errors have been
-encounted. Do not start or stop the device here. That will be handled from outside the `onDeviceDataLoop()` callback.
-
-The invocation of the `onDeviceDataLoop()` callback will be handled by miniaudio. When you start the device, miniaudio will fire this
-callback. When the device is stopped, the `ma_device_get_state() == MA_STATE_STARTED` condition will fail and the loop will be terminated
-which will then fall through to the part that stops the device. For an example on how to implement the `onDeviceDataLoop()` callback,
-look at `ma_device_audio_thread__default_read_write()`. Implement the `onDeviceDataLoopWakeup()` callback if you need a mechanism to
-wake up the audio thread.

-Initializes a `ma_context_config` object.
-
-
-Return Value
-------------
-A `ma_context_config` initialized to defaults.
-
-
-Remarks
--------
-You must always use this to initialize the default state of the `ma_context_config` object. Not using this will result in your program breaking when miniaudio
-is updated and new members are added to `ma_context_config`. It also sets logical defaults.
-
-You can override members of the returned object by changing it's members directly.

-Initializes a context.
-
-The context is used for selecting and initializing an appropriate backend and to represent the backend at a more global level than that of an individual
-device. There is one context to many devices, and a device is created from a context. A context is required to enumerate devices.
-
-
-Parameters
-----------
-backends (in, optional)
- A list of backends to try initializing, in priority order. Can be NULL, in which case it uses default priority order.
-
-backendCount (in, optional)
- The number of items in `backend`. Ignored if `backend` is NULL.
-
-pConfig (in, optional)
- The context configuration.
-
-pContext (in)
- A pointer to the context object being initialized.
-
-
-Return Value
-------------
-MA_SUCCESS if successful; any other error code otherwise.
-
-
-Thread Safety
--------------
-Unsafe. Do not call this function across multiple threads as some backends read and write to global state.
-
-
-Remarks
--------
-When `backends` is NULL, the default priority order will be used. Below is a list of backends in priority order:
-
- |-------------|-----------------------|--------------------------------------------------------|
- | Name | Enum Name | Supported Operating Systems |
- |-------------|-----------------------|--------------------------------------------------------|
- | WASAPI | ma_backend_wasapi | Windows Vista+ |
- | DirectSound | ma_backend_dsound | Windows XP+ |
- | WinMM | ma_backend_winmm | Windows XP+ (may work on older versions, but untested) |
- | Core Audio | ma_backend_coreaudio | macOS, iOS |
- | ALSA | ma_backend_alsa | Linux |
- | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) |
- | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) |
- | sndio | ma_backend_sndio | OpenBSD |
- | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD |
- | OSS | ma_backend_oss | FreeBSD |
- | AAudio | ma_backend_aaudio | Android 8+ |
- | OpenSL|ES | ma_backend_opensl | Android (API level 16+) |
- | Web Audio | ma_backend_webaudio | Web (via Emscripten) |
- | Null | ma_backend_null | Cross Platform (not used on Web) |
- |-------------|-----------------------|--------------------------------------------------------|
-
-The context can be configured via the `pConfig` argument. The config object is initialized with `ma_context_config_init()`. Individual configuration settings
-can then be set directly on the structure. Below are the members of the `ma_context_config` object.
-
- logCallback
- Callback for handling log messages from miniaudio.
-
- threadPriority
- The desired priority to use for the audio thread. Allowable values include the following:
-
- |--------------------------------------|
- | Thread Priority |
- |--------------------------------------|
- | ma_thread_priority_idle |
- | ma_thread_priority_lowest |
- | ma_thread_priority_low |
- | ma_thread_priority_normal |
- | ma_thread_priority_high |
- | ma_thread_priority_highest (default) |
- | ma_thread_priority_realtime |
- | ma_thread_priority_default |
- |--------------------------------------|
-
- pUserData
- A pointer to application-defined data. This can be accessed from the context object directly such as `context.pUserData`.
-
- allocationCallbacks
- Structure containing custom allocation callbacks. Leaving this at defaults will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. These allocation
- callbacks will be used for anything tied to the context, including devices.
-
- alsa.useVerboseDeviceEnumeration
- ALSA will typically enumerate many different devices which can be intrusive and not user-friendly. To combat this, miniaudio will enumerate only unique
- card/device pairs by default. The problem with this is that you lose a bit of flexibility and control. Setting alsa.useVerboseDeviceEnumeration makes
- it so the ALSA backend includes all devices. Defaults to false.
-
- pulse.pApplicationName
- PulseAudio only. The application name to use when initializing the PulseAudio context with `pa_context_new()`.
-
- pulse.pServerName
- PulseAudio only. The name of the server to connect to with `pa_context_connect()`.
-
- pulse.tryAutoSpawn
- PulseAudio only. Whether or not to try automatically starting the PulseAudio daemon. Defaults to false. If you set this to true, keep in mind that
- miniaudio uses a trial and error method to find the most appropriate backend, and this will result in the PulseAudio daemon starting which may be
- intrusive for the end user.
-
- coreaudio.sessionCategory
- iOS only. The session category to use for the shared AudioSession instance. Below is a list of allowable values and their Core Audio equivalents.
-
- |-----------------------------------------|-------------------------------------|
- | miniaudio Token | Core Audio Token |
- |-----------------------------------------|-------------------------------------|
- | ma_ios_session_category_ambient | AVAudioSessionCategoryAmbient |
- | ma_ios_session_category_solo_ambient | AVAudioSessionCategorySoloAmbient |

-
-It is recommended that only a single context is active at any given time because it's a bulky data structure which performs run-time linking for the
-relevant backends every time it's initialized.
-
-The location of the context cannot change throughout it's lifetime. Consider allocating the `ma_context` object with `malloc()` if this is an issue. The
-reason for this is that a pointer to the context is stored in the `ma_device` structure.
-
-
-Example 1 - Default Initialization
-----------------------------------
-The example below shows how to initialize the context using the default configuration.
-
-```c
-ma_context context;
-ma_result result = ma_context_init(NULL, 0, NULL, &context);
-if (result != MA_SUCCESS) {
- // Error.
-}
-```
-
-
-Example 2 - Custom Configuration
---------------------------------
-The example below shows how to initialize the context using custom backend priorities and a custom configuration. In this hypothetical example, the program
-wants to prioritize ALSA over PulseAudio on Linux. They also want to avoid using the WinMM backend on Windows because it's latency is too high. They also
-want an error to be returned if no valid backend is available which they achieve by excluding the Null backend.
-
-For the configuration, the program wants to capture any log messages so they can, for example, route it to a log file and user interface.
-
-```c
-ma_backend backends[] = {
- ma_backend_alsa,
- ma_backend_pulseaudio,
- ma_backend_wasapi,
- ma_backend_dsound
-};
-
-ma_context_config config = ma_context_config_init();
-config.logCallback = my_log_callback;
-config.pUserData = pMyUserData;
-
-ma_context context;
-ma_result result = ma_context_init(backends, sizeof(backends)/sizeof(backends[0]), &config, &context);
-if (result != MA_SUCCESS) {
- // Error.
- if (result == MA_NO_BACKEND) {
- // Couldn't find an appropriate backend.
- }
-}
-```

-
-Note that this only retrieves the ID and name/description of the device. The reason for only retrieving basic information is that it would otherwise require

-Initializes a device.
-
-A device represents a physical audio device. The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it
-from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be
-playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the
-device is done via a callback which is fired by miniaudio at periodic time intervals.
-
-The frequency at which data is delivered to and from a device depends on the size of it's period. The size of the period can be defined in terms of PCM frames
-or milliseconds, whichever is more convenient. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and
-increased risk of glitching due to the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but
-miniaudio's defaults should work fine for most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple
-media player you can make it larger. Note that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the
-backend is ultimately responsible for what it gives you. You cannot assume you will get exactly what you ask for.
-
-When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the
-format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you
-can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline.
-
-
-Parameters
-----------
-pContext (in, optional)
- A pointer to the context that owns the device. This can be null, in which case it creates a default context internally.
-
-pConfig (in)
- A pointer to the device configuration. Cannot be null. See remarks for details.
-
-pDevice (out)
- A pointer to the device object being initialized.
-
-
-Return Value
-------------
-MA_SUCCESS if successful; any other error code otherwise.
-
-
-Thread Safety
--------------
-Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to
-calling this at the same time as `ma_device_uninit()`.
-
-
-Callback Safety
----------------
-Unsafe. It is not safe to call this inside any callback.
-
-
-Remarks
--------
-Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so:
-
- ```c
- ma_context_init(NULL, 0, NULL, &context);
- ```
-
-Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use
-device.pContext for the initialization of other devices.
-
-The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can
-then be set directly on the structure. Below are the members of the `ma_device_config` object.
-
- deviceType
- Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`.
-
- sampleRate
- The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate.
-
- periodSizeInFrames
- The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will
- be used depending on the selected performance profile. This value affects latency. See below for details.
-
- periodSizeInMilliseconds
- The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be
- used depending on the selected performance profile. The value affects latency. See below for details.
-
- periods
- The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by
- this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured.
-
- performanceProfile
- A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or
- `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value.
-
- noPreZeroedOutputBuffer
- When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of
- the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data
- callback will write to every sample in the output buffer, or if you are doing your own clearing.
-
- noClip
- When set to true, the contents of the output buffer passed into the data callback will be clipped after returning. When set to false (default), the
- contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or not the clip. This only
- applies when the playback sample format is f32.
-
- dataCallback
- The callback to fire whenever data is ready to be delivered to or from the device.
-
- stopCallback
- The callback to fire whenever the device has stopped, either explicitly via `ma_device_stop()`, or implicitly due to things like the device being
- disconnected.
-
- pUserData
- The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`.
-
- resampling.algorithm
- The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The
- default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`.
-
- resampling.linear.lpfOrder
- The linear resampler applies a low-pass filter as part of it's procesing for anti-aliasing. This setting controls the order of the filter. The higher
- the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is
- `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`.
-
- playback.pDeviceID
- A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's
- default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
-
- playback.format
- The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
- initialization from the device object directly with `device.playback.format`.
-
- playback.channels
- The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
- from the device object directly with `device.playback.channels`.
-
- playback.channelMap
- The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
- device object direct with `device.playback.channelMap`.
-
- playback.shareMode
- The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
- exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
- ma_share_mode_shared and reinitializing.
-
- capture.pDeviceID
- A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize. Setting this NULL (default) will use the system's
- default capture device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
-
- capture.format
- The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
- initialization from the device object directly with `device.capture.format`.
-
- capture.channels
- The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
- from the device object directly with `device.capture.channels`.
-
- capture.channelMap
- The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
- device object direct with `device.capture.channelMap`.
-
- capture.shareMode
- The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
- exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to
- ma_share_mode_shared and reinitializing.
-
- wasapi.noAutoConvertSRC
- WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false.
-
- wasapi.noDefaultQualitySRC
- WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`.
- You should usually leave this set to false, which is the default.
-
- wasapi.noAutoStreamRouting
- WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false.
-
- wasapi.noHardwareOffloading
- WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false.
-
- alsa.noMMap
- ALSA only. When set to true, disables MMap mode. Defaults to false.
-
- alsa.noAutoFormat
- ALSA only. When set to true, disables ALSA's automatic format conversion by including the SND_PCM_NO_AUTO_FORMAT flag. Defaults to false.
-
- alsa.noAutoChannels
- ALSA only. When set to true, disables ALSA's automatic channel conversion by including the SND_PCM_NO_AUTO_CHANNELS flag. Defaults to false.
-
- alsa.noAutoResample
- ALSA only. When set to true, disables ALSA's automatic resampling by including the SND_PCM_NO_AUTO_RESAMPLE flag. Defaults to false.
-
- pulse.pStreamNamePlayback
- PulseAudio only. Sets the stream name for playback.
-
- pulse.pStreamNameCapture
- PulseAudio only. Sets the stream name for capture.
-
- coreaudio.allowNominalSampleRateChange
- Core Audio only. Desktop only. When enabled, allows the sample rate of the device to be changed at the operating system level. This
- is disabled by default in order to prevent intrusive changes to the user's system. This is useful if you want to use a sample rate
- that is known to be natively supported by the hardware thereby avoiding the cost of resampling. When set to true, miniaudio will
- find the closest match between the sample rate requested in the device config and the sample rates natively supported by the
- hardware. When set to false, the sample rate currently set by the operating system will always be used.
-
-
-Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device.
-
-After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`.
-
-If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or
-`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or
-`ma_performance_profile_conservative`.
-
-If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device
-in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the
-config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA,
-for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user.
-Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary.
-
-When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config
-and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run
-on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`,
-`playback/capture.channels` and `sampleRate` members of the device object.
-
-When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message
-asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information.
-
-ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture.
-If these fail it will try falling back to the "hw" device.
-
-
-Example 1 - Simple Initialization
----------------------------------
-This example shows how to initialize a simple playback device using a standard configuration. If you are just needing to do simple playback from the default
-playback device this is usually all you need.
-
-```c
-ma_device_config config = ma_device_config_init(ma_device_type_playback);
-config.playback.format = ma_format_f32;
-config.playback.channels = 2;
-config.sampleRate = 48000;
-config.dataCallback = ma_data_callback;
-config.pMyUserData = pMyUserData;
-
-ma_device device;
-ma_result result = ma_device_init(NULL, &config, &device);
-if (result != MA_SUCCESS) {
- // Error
-}
-```
-
-
-Example 2 - Advanced Initialization
------------------------------------
-This example shows how you might do some more advanced initialization. In this hypothetical example we want to control the latency by setting the buffer size
-and period count. We also want to allow the user to be able to choose which device to output from which means we need a context so we can perform device
-enumeration.
-
-```c
-ma_context context;
-ma_result result = ma_context_init(NULL, 0, NULL, &context);
-if (result != MA_SUCCESS) {
- // Error
-}
-
-ma_device_info* pPlaybackDeviceInfos;
-ma_uint32 playbackDeviceCount;
-result = ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, NULL, NULL);
-if (result != MA_SUCCESS) {
- // Error
-}
-
-// ... choose a device from pPlaybackDeviceInfos ...
-
-ma_device_config config = ma_device_config_init(ma_device_type_playback);
-config.playback.pDeviceID = pMyChosenDeviceID; // <-- Get this from the `id` member of one of the `ma_device_info` objects returned by ma_context_get_devices().

-`pDescriptor` object. Since buffer size calculations based on time depends on the sample rate, a

- The device's native sample rate. This is only ever used when the `periodSizeInFrames` member of

--------
-If you want to retrieve the number of backends so you can determine the capacity of `pBackends` buffer, you can call

-
-This will also enumerate the null backend. If you don't want to include this you need to check for `ma_backend_null`
-when you enumerate over the returned backends and handle it appropriately. Alternatively, you can disable it at
-compile time with `MA_NO_NULL`.
-
-The returned backends are determined based on compile time settings, not the platform it's currently running on. For

- We could define ma_device_uninit() such that it must be called on the same thread as

- resampling.
-
- To reproduce this problem, open the "plug:dmix" device, and set the sample rate to 44100. Internally, it looks like dmix uses a
- sample rate of 48000. The hardware parameters will get set correctly with no errors, but it looks like the 44100 -> 48000 resampling
- doesn't work properly - but only with MMAP access mode. You will notice skipping/crackling in the audio, and it'll run at a slightly
- faster rate.
-
- miniaudio has built-in support for sample rate conversion (albeit low quality at the moment), so disabling resampling should be fine
- for us. The only problem is that it won't be taking advantage of any kind of hardware-accelerated resampling and it won't be very
- good quality until I get a chance to improve the quality of miniaudio's software sample rate conversion.
-
- I don't currently know if the dmix plugin is the only one with this error. Indeed, this is the only one I've been able to reproduce
- this error with. In the future, we may want to restrict the disabling of resampling to only known bad plugins.

-PulseAudio Backend
-
-******************************************************************************/
-#ifdef MA_HAS_PULSEAUDIO
-/*
-The PulseAudio API, along with Apple's Core Audio, is the worst of the maintream audio APIs. This is a brief description of what's going on
-in the PulseAudio backend. I apologize if this gets a bit ranty for your liking - you might want to skip this discussion.
-
-PulseAudio has something they call the "Simple API", which unfortunately isn't suitable for miniaudio. I've not seen anywhere where it
-allows you to enumerate over devices, nor does it seem to support the ability to stop and start streams. Looking at the documentation, it
-appears as though the stream is constantly running and you prevent sound from being emitted or captured by simply not calling the read or
-write functions. This is not a professional solution as it would be much better to *actually* stop the underlying stream. Perhaps the
-simple API has some smarts to do this automatically, but I'm not sure. Another limitation with the simple API is that it seems inefficient
-when you want to have multiple streams to a single context. For these reasons, miniaudio is not using the simple API.
-
-Since we're not using the simple API, we're left with the asynchronous API as our only other option. And boy, is this where it starts to
-get fun, and I don't mean that in a good way...
-
-The problems start with the very name of the API - "asynchronous". Yes, this is an asynchronous oriented API which means your commands
-don't immediately take effect. You instead need to issue your commands, and then wait for them to complete. The waiting mechanism is
-enabled through the use of a "main loop". In the asychronous API you cannot get away from the main loop, and the main loop is where almost
-all of PulseAudio's problems stem from.
-
-When you first initialize PulseAudio you need an object referred to as "main loop". You can implement this yourself by defining your own
-vtable, but it's much easier to just use one of the built-in main loop implementations. There's two generic implementations called
-pa_mainloop and pa_threaded_mainloop, and another implementation specific to GLib called pa_glib_mainloop. We're using pa_threaded_mainloop
-because it simplifies management of the worker thread. The idea of the main loop object is pretty self explanatory - you're supposed to use
-it to implement a worker thread which runs in a loop. The main loop is where operations are actually executed.
-
-To initialize the main loop, you just use `pa_threaded_mainloop_new()`. This is the first function you'll call. You can then get a pointer
-to the vtable with `pa_threaded_mainloop_get_api()` (the main loop vtable is called `pa_mainloop_api`). Again, you can bypass the threaded
-main loop object entirely and just implement `pa_mainloop_api` directly, but there's no need for it unless you're doing something extremely
-specialized such as if you want to integrate it into your application's existing main loop infrastructure.
-
-(EDIT 2021-01-26: miniaudio is no longer using `pa_threaded_mainloop` due to this issue: https://github.com/mackron/miniaudio/issues/262.
-It is now using `pa_mainloop` which turns out to be a simpler solution anyway. The rest of this rant still applies, however.)
-
-Once you have your main loop vtable (the `pa_mainloop_api` object) you can create the PulseAudio context. This is very similar to
-miniaudio's context and they map to each other quite well. You have one context to many streams, which is basically the same as miniaudio's
-one `ma_context` to many `ma_device`s. Here's where it starts to get annoying, however. When you first create the PulseAudio context, which
-is done with `pa_context_new()`, it's not actually connected to anything. When you connect, you call `pa_context_connect()`. However, if
-you remember, PulseAudio is an asynchronous API. That means you cannot just assume the context is connected after `pa_context_context()`
-has returned. You instead need to wait for it to connect. To do this, you need to either wait for a callback to get fired, which you can
-set with `pa_context_set_state_callback()`, or you can continuously poll the context's state. Either way, you need to run this in a loop.
-All objects from here out are created from the context, and, I believe, you can't be creating these objects until the context is connected.
-This waiting loop is therefore unavoidable. In order for the waiting to ever complete, however, the main loop needs to be running. Before
-attempting to connect the context, the main loop needs to be started with `pa_threaded_mainloop_start()`.
-
-The reason for this asynchronous design is to support cases where you're connecting to a remote server, say through a local network or an
-internet connection. However, the *VAST* majority of cases don't involve this at all - they just connect to a local "server" running on the
-host machine. The fact that this would be the default rather than making `pa_context_connect()` synchronous tends to boggle the mind.
-
-Once the context has been created and connected you can start creating a stream. A PulseAudio stream is analogous to miniaudio's device.
-The initialization of a stream is fairly standard - you configure some attributes (analogous to miniaudio's device config) and then call
-`pa_stream_new()` to actually create it. Here is where we start to get into "operations". When configuring the stream, you can get
-information about the source (such as sample format, sample rate, etc.), however it's not synchronous. Instead, a `pa_operation` object
-is returned from `pa_context_get_source_info_by_name()` (capture) or `pa_context_get_sink_info_by_name()` (playback). Then, you need to
-run a loop (again!) to wait for the operation to complete which you can determine via a callback or polling, just like we did with the
-context. Then, as an added bonus, you need to decrement the reference counter of the `pa_operation` object to ensure memory is cleaned up.
-All of that just to retrieve basic information about a device!
-
-Once the basic information about the device has been retrieved, miniaudio can now create the stream with `ma_stream_new()`. Like the
-context, this needs to be connected. But we need to be careful here, because we're now about to introduce one of the most horrific design
-choices in PulseAudio.
-
-PulseAudio allows you to specify a callback that is fired when data can be written to or read from a stream. The language is important here
-because PulseAudio takes it literally, specifically the "can be". You would think these callbacks would be appropriate as the place for
-writing and reading data to and from the stream, and that would be right, except when it's not. When you initialize the stream, you can
-set a flag that tells PulseAudio to not start the stream automatically. This is required because miniaudio does not auto-start devices
-straight after initialization - you need to call `ma_device_start()` manually. The problem is that even when this flag is specified,
-PulseAudio will immediately fire it's write or read callback. This is *technically* correct (based on the wording in the documentation)
-because indeed, data *can* be written at this point. The problem is that it's not *practical*. It makes sense that the write/read callback
-would be where a program will want to write or read data to or from the stream, but when it's called before the application has even
-requested that the stream be started, it's just not practical because the program probably isn't ready for any kind of data delivery at
-that point (it may still need to load files or whatnot). Instead, this callback should only be fired when the application requests the
-stream be started which is how it works with literally *every* other callback-based audio API. Since miniaudio forbids firing of the data
-callback until the device has been started (as it should be with *all* callback based APIs), logic needs to be added to ensure miniaudio
-doesn't just blindly fire the application-defined data callback from within the PulseAudio callback before the stream has actually been
-started. The device state is used for this - if the state is anything other than `MA_STATE_STARTING` or `MA_STATE_STARTED`, the main data
-callback is not fired.
-
-This, unfortunately, is not the end of the problems with the PulseAudio write callback. Any normal callback based audio API will
-continuously fire the callback at regular intervals based on the size of the internal buffer. This will only ever be fired when the device
-is running, and will be fired regardless of whether or not the user actually wrote anything to the device/stream. This not the case in
-PulseAudio. In PulseAudio, the data callback will *only* be called if you wrote something to it previously. That means, if you don't call
-`pa_stream_write()`, the callback will not get fired. On the surface you wouldn't think this would matter because you should be always
-writing data, and if you don't have anything to write, just write silence. That's fine until you want to drain the stream. You see, if
-you're continuously writing data to the stream, the stream will never get drained! That means in order to drain the stream, you need to
-*not* write data to it! But remember, when you don't write data to the stream, the callback won't get fired again! Why is draining
-important? Because that's how we've defined stopping to work in miniaudio. In miniaudio, stopping the device requires it to be drained
-before returning from ma_device_stop(). So we've stopped the device, which requires us to drain, but draining requires us to *not* write
-data to the stream (or else it won't ever complete draining), but not writing to the stream means the callback won't get fired again!
-
-This becomes a problem when stopping and then restarting the device. When the device is stopped, it's drained, which requires us to *not*
-write anything to the stream. But then, since we didn't write anything to it, the write callback will *never* get called again if we just
-resume the stream naively. This means that starting the stream requires us to write data to the stream from outside the callback. This
-disconnect is something PulseAudio has got seriously wrong - there should only ever be a single source of data delivery, that being the
-callback. (I have tried using `pa_stream_flush()` to trigger the write callback to fire, but this just doesn't work for some reason.)
-
-Once you've created the stream, you need to connect it which involves the whole waiting procedure. This is the same process as the context,
-only this time you'll poll for the state with `pa_stream_get_status()`. The starting and stopping of a streaming is referred to as
-"corking" in PulseAudio. The analogy is corking a barrel. To start the stream, you uncork it, to stop it you cork it. Personally I think
-it's silly - why would you not just call it "starting" and "stopping" like any other normal audio API? Anyway, the act of corking is, you
-guessed it, asynchronous. This means you'll need our waiting loop as usual. Again, why this asynchronous design is the default is
-absolutely beyond me. Would it really be that hard to just make it run synchronously?
-
-Teardown is pretty simple (what?!). It's just a matter of calling the relevant `_unref()` function on each object in reverse order that
-they were initialized in.
-
-That's about it from the PulseAudio side. A bit ranty, I know, but they really need to fix that main loop and callback system. They're
-embarrassingly unpractical. The main loop thing is an easy fix - have synchronous versions of all APIs. If an application wants these to
-run asynchronously, they can execute them in a separate thread themselves. The desire to run these asynchronously is such a niche
-requirement - it makes no sense to make it the default. The stream write callback needs to be change, or an alternative provided, that is
-constantly fired, regardless of whether or not `pa_stream_write()` has been called, and it needs to take a pointer to a buffer as a
-parameter which the program just writes to directly rather than having to call `pa_stream_writable_size()` and `pa_stream_write()`. These
-changes alone will change PulseAudio from one of the worst audio APIs to one of the best.

-Core Audio
-
-So far, Core Audio has been the worst backend to work with due to being both unintuitive and having almost no documentation
-apart from comments in the headers (which admittedly are quite good). For my own purposes, and for anybody out there whose
-needing to figure out how this darn thing works, I'm going to outline a few things here.
-
-Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be
-able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen
-that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent
-and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the
-distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API.
-
-Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When
-retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific
-data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the
-devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be
-the central APIs for retrieving information about the system and specific devices.
-
-To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a
-structure with three variables and is used to identify which property you are getting or setting. The first is the "selector"
-which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is
-typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and
-kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to
-kAudioObjectPropertyElementMaster in miniaudio's case. I don't know of any cases where this would be set to anything different.
-
-Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size
-of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property
-address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the
-size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of
-AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count.

- Technical Note TN2091: Device input using the HAL Output Audio Unit
- https://developer.apple.com/library/archive/technotes/tn2091/_index.html
-
- This documentation says the following:
-
- The internal AudioConverter can handle any *simple* conversion. Typically, this means that a client can specify ANY
- variant of the PCM formats. Consequently, the device's sample rate should match the desired sample rate. If sample rate
- conversion is needed, it can be accomplished by buffering the input and converting the data on a separate thread with
- another AudioConverter.
-
- The important part here is the mention that it can handle *simple* conversions, which does *not* include sample rate. We
- therefore want to ensure the sample rate stays consistent. This document is specifically for input, but I'm going to play it
- safe and apply the same rule to output as well.
-
- I have tried going against the documentation by setting the sample rate anyway, but this just results in AudioUnitRender()
- returning a result code of -10863. I have also tried changing the format directly on the input scope on the input bus, but
- this just results in `ca_require: IsStreamFormatWritable(inScope, inElement) NotWritable` when trying to set the format.
-
- Something that does seem to work, however, has been setting the nominal sample rate on the deivce object. The problem with
- this, however, is that it actually changes the sample rate at the operating system level and not just the application. This
- could be intrusive to the user, however, so I don't think it's wise to make this the default. Instead I'm making this a
- configuration option. When the `coreaudio.allowNominalSampleRateChange` config option is set to true, changing the sample
- rate will be allowed. Otherwise it'll be fixed to the current sample rate. To check the system-defined sample rate, run
- the Audio MIDI Setup program that comes installed on macOS and observe how the sample rate changes as the sample rate is
- changed by miniaudio.

-Note on Starting and Stopping
-=============================
-In the past I was using SNDCTL_DSP_HALT to stop the device, however this results in issues when
-trying to resume the device again. If we use SNDCTL_DSP_HALT, the next write() or read() will
-fail. Instead what we need to do is just not write or read to and from the device when the
-device is not running.
-
-As a result, both the start and stop functions for OSS are just empty stubs. The starting and
-stopping logic is handled by ma_device_write__oss() and ma_device_read__oss(). These will check
-the device state, and if the device is stopped they will simply not do any kind of processing.
-
-The downside to this technique is that I've noticed a fairly lengthy delay in stopping the
-device, up to a second. This is on a virtual machine, and as such might just be due to the
-virtual drivers, but I'm not fully sure. I am not sure how to work around this problem so for
-the moment that's just how it's going to have to be.
-
-When starting the device, OSS will automatically start it when write() or read() is called.

- ScriptProcessorNode is actually deprecated so this is likely to be temporary. The way this works for playback is very simple. You just set a callback

- something called AudioWorklets which _forces_ you to load a _separate_ .js file at run time... nice... Hopefully ScriptProcessorNode will continue to
- work for years to come, but this may need to change to use AudioSourceBufferNode instead, which I think is what Emscripten uses for it's built-in SDL
- implementation. I'll be avoiding that insane AudioWorklet API like the plague...
-
- For capture it is a bit unintuitive. We use the ScriptProccessorNode _only_ to get the raw PCM data. It is connected to an AudioContext just like the
- playback case, however we just output silence to the AudioContext instead of passing any real data. It would make more sense to me to use the
- MediaRecorder API, but unfortunately you need to specify a MIME time (Opus, Vorbis, etc.) for the binary blob that's returned to the client, but I've
- been unable to figure out how to get this as raw PCM. The closest I can think is to use the MIME type for WAV files and just parse it, but I don't know
- how well this would work. Although ScriptProccessorNode is deprecated, in practice it seems to have pretty good browser support so I'm leaving it like
- this for now. If anyone knows how I could get raw PCM data using the MediaRecorder API please let me know!

- Imagine the following simplified example: You have a single input speaker which is the front/left speaker which you want to convert to
- the following output configuration:
-
- - front/left
- - side/left
- - back/left
-
- The front/left output is easy - it the same speaker position so it receives the full contribution of the front/left input. The amount
- of contribution to apply to the side/left and back/left speakers, however, is a bit more complicated.
-
- Imagine the front/left speaker as emitting audio from two planes - the front plane and the left plane. You can think of the front/left
- speaker emitting half of it's total volume from the front, and the other half from the left. Since part of it's volume is being emitted
- from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would
- receive some amount of contribution from front/left speaker. The amount of contribution depends on how many planes are shared between
- the two speakers. Note that in the examples below I've added a top/front/left speaker as an example just to show how the math works
- across 3 spatial dimensions.
-
- The first thing to do is figure out how each speaker's volume is spread over each of plane:
- - front/left: 2 planes (front and left) = 1/2 = half it's total volume on each plane
- - side/left: 1 plane (left only) = 1/1 = entire volume from left plane
- - back/left: 2 planes (back and left) = 1/2 = half it's total volume on each plane
- - top/front/left: 3 planes (top, front and left) = 1/3 = one third it's total volume on each plane
-
- The amount of volume each channel contributes to each of it's planes is what controls how much it is willing to given and take to other
- channels on the same plane. The volume that is willing to the given by one channel is multiplied by the volume that is willing to be
- taken by the other to produce the final contribution.

-RELEASE NOTES - VERSION 0.10.x
-==============================
-Version 0.10 includes major API changes and refactoring, mostly concerned with the data conversion system. Data conversion is performed internally to convert
-audio data between the format requested when initializing the `ma_device` object and the format of the internal device used by the backend. The same applies
-to the `ma_decoder` object. The previous design has several design flaws and missing features which necessitated a complete redesign.
-
-
-Changes to Data Conversion
---------------------------
-The previous data conversion system used callbacks to deliver input data for conversion. This design works well in some specific situations, but in other
-situations it has some major readability and maintenance issues. The decision was made to replace this with a more iterative approach where you just pass in a
-pointer to the input data directly rather than dealing with a callback.
-
-The following are the data conversion APIs that have been removed and their replacements:
-
- - ma_format_converter -> ma_convert_pcm_frames_format()
- - ma_channel_router -> ma_channel_converter
- - ma_src -> ma_resampler
- - ma_pcm_converter -> ma_data_converter
-
-The previous conversion APIs accepted a callback in their configs. There are no longer any callbacks to deal with. Instead you just pass the data into the
-`*_process_pcm_frames()` function as a pointer to a buffer.
-
-The simplest aspect of data conversion is sample format conversion. To convert between two formats, just call `ma_convert_pcm_frames_format()`. Channel
-conversion is also simple which you can do with `ma_channel_converter` via `ma_channel_converter_process_pcm_frames()`.
-
-Resampling is more complicated because the number of output frames that are processed is different to the number of input frames that are consumed. When you
-call `ma_resampler_process_pcm_frames()` you need to pass in the number of input frames available for processing and the number of output frames you want to
-output. Upon returning they will receive the number of input frames that were consumed and the number of output frames that were generated.
-
-The `ma_data_converter` API is a wrapper around format, channel and sample rate conversion and handles all of the data conversion you'll need which probably
-makes it the best option if you need to do data conversion.
-
-In addition to changes to the API design, a few other changes have been made to the data conversion pipeline:
-
- - The sinc resampler has been removed. This was completely broken and never actually worked properly.
- - The linear resampler now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with the
- `lpfOrder` option, which has a maximum value of MA_MAX_FILTER_ORDER.
- - Data conversion now supports s16 natively which runs through a fixed point pipeline. Previously everything needed to be converted to floating point before
- processing, whereas now both s16 and f32 are natively supported. Other formats still require conversion to either s16 or f32 prior to processing, however
- `ma_data_converter` will handle this for you.
-
-
-Custom Memory Allocators
-------------------------
-miniaudio has always supported macro level customization for memory allocation via MA_MALLOC, MA_REALLOC and MA_FREE, however some scenarios require more
-flexibility by allowing a user data pointer to be passed to the custom allocation routines. Support for this has been added to version 0.10 via the
-`ma_allocation_callbacks` structure. Anything making use of heap allocations has been updated to accept this new structure.
-
-The `ma_context_config` structure has been updated with a new member called `allocationCallbacks`. Leaving this set to it's defaults returned by
-`ma_context_config_init()` will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. Likewise, The `ma_decoder_config` structure has been updated in the same
-way, and leaving everything as-is after `ma_decoder_config_init()` will cause it to use the same defaults.
-
-The following APIs have been updated to take a pointer to a `ma_allocation_callbacks` object. Setting this parameter to NULL will cause it to use defaults.
-Otherwise they will use the relevant callback in the structure.
-
- - ma_malloc()
- - ma_realloc()
- - ma_free()
- - ma_aligned_malloc()
- - ma_aligned_free()
- - ma_rb_init() / ma_rb_init_ex()
- - ma_pcm_rb_init() / ma_pcm_rb_init_ex()
-
-Note that you can continue to use MA_MALLOC, MA_REALLOC and MA_FREE as per normal. These will continue to be used by default if you do not specify custom
-allocation callbacks.
-
-
-Buffer and Period Configuration Changes
----------------------------------------
-The way in which the size of the internal buffer and periods are specified in the device configuration have changed. In previous versions, the config variables
-`bufferSizeInFrames` and `bufferSizeInMilliseconds` defined the size of the entire buffer, with the size of a period being the size of this variable divided by
-the period count. This became confusing because people would expect the value of `bufferSizeInFrames` or `bufferSizeInMilliseconds` to independantly determine
-latency, when in fact it was that value divided by the period count that determined it. These variables have been removed and replaced with new ones called
-`periodSizeInFrames` and `periodSizeInMilliseconds`.
-
-These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is
-that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to
-configure latency.
-
-The following unused APIs have been removed:
-
- ma_get_default_buffer_size_in_milliseconds()
- ma_get_default_buffer_size_in_frames()
-
-The following macros have been removed:
-
- MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY
- MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE
-
-
-Other API Changes
------------------
-Other less major API changes have also been made in version 0.10.
-
-`ma_device_set_stop_callback()` has been removed. If you require a stop callback, you must now set it via the device config just like the data callback.
-
-The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including
-sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes a configuration
-object called `ma_waveform_config` which defines the properties of the waveform. Use `ma_waveform_config_init()` to initialize a `ma_waveform_config` object.
-Use `ma_waveform_read_pcm_frames()` in place of `ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`.
-
-`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies
-the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to
-take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it more flexible, to
-prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added.
-
-`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API.
-
-
-Filters
--------
-The following filters have been added:
-
- |-------------|-------------------------------------------------------------------|
- | API | Description |
- |-------------|-------------------------------------------------------------------|
- | ma_biquad | Biquad filter (transposed direct form 2) |
- | ma_lpf1 | First order low-pass filter |
- | ma_lpf2 | Second order low-pass filter |
- | ma_lpf | High order low-pass filter (Butterworth) |
- | ma_hpf1 | First order high-pass filter |
- | ma_hpf2 | Second order high-pass filter |
- | ma_hpf | High order high-pass filter (Butterworth) |
- | ma_bpf2 | Second order band-pass filter |
- | ma_bpf | High order band-pass filter |
- | ma_peak2 | Second order peaking filter |
- | ma_notch2 | Second order notching filter |
- | ma_loshelf2 | Second order low shelf filter |
- | ma_hishelf2 | Second order high shelf filter |
- |-------------|-------------------------------------------------------------------|
-
-These filters all support 32-bit floating point and 16-bit signed integer formats natively. Other formats need to be converted beforehand.
-
-
-Sine, Square, Triangle and Sawtooth Waveforms
----------------------------------------------
-Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old
-`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_config_init()` to initialize a config object, and then pass it
-into `ma_waveform_init()`. Then use `ma_waveform_read_pcm_frames()` to read PCM data.
-
-
-Noise Generation
-----------------
-A noise generation API has been added. This is used via the `ma_noise` API. Currently white, pink and Brownian noise is supported. The `ma_noise` API is
-similar to the waveform API. Use `ma_noise_config_init()` to initialize a config object, and then pass it into `ma_noise_init()` to initialize a `ma_noise`
-object. Then use `ma_noise_read_pcm_frames()` to read PCM data.
-
-
-Miscellaneous Changes
----------------------
-The MA_NO_STDIO option has been removed. This would disable file I/O APIs, however this has proven to be too hard to maintain for it's perceived value and was
-therefore removed.
-
-Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report.
-
-The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on
-the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it
-was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work,
-this has been removed from all structures.
-
-Results codes have been overhauled. Unnecessary result codes have been removed, and some have been renumbered for organisation purposes. If you are are binding
-maintainer you will need to update your result codes. Support has also been added for retrieving a human readable description of a given result code via the
-`ma_result_description()` API.
-
-ALSA: The automatic format conversion, channel conversion and resampling performed by ALSA is now disabled by default as they were causing some compatibility
-issues with certain devices and configurations. These can be individually enabled via the device config:
-
- ```c
- deviceConfig.alsa.noAutoFormat = MA_TRUE;
- deviceConfig.alsa.noAutoChannels = MA_TRUE;
- deviceConfig.alsa.noAutoResample = MA_TRUE;
- ```

-RELEASE NOTES - VERSION 0.9.x
-=============================
-Version 0.9 includes major API changes, centered mostly around full-duplex and the rebrand to "miniaudio". Before I go into detail about the major changes I
-would like to apologize. I know it's annoying dealing with breaking API changes, but I think it's best to get these changes out of the way now while the
-library is still relatively young and unknown.
-
-There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in advance for this. You may want to
-hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for you, and you don't need full-duplex support, you can avoid upgrading
-(though you won't be getting future bug fixes).
-
-
-Rebranding to "miniaudio"
--------------------------
-The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple:
-
-1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and
-2) I don't like the look of the underscore.
-
-This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's better to get this out of the road
-now rather than later. Also, since there are necessary API changes for full-duplex support I think it's better to just get the namespace change over and done
-with at the same time as the full-duplex changes. I'm hoping this will be the last of the major API changes. Fingers crossed!
-
-The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's your preference.
-
-
-Full-Duplex Support
--------------------
-The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes.
-
-1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted to avoid a third callback just
- for full-duplex so the decision was made to break this API and unify the callbacks. Now, there is just one callback which is the same for all three modes
- (playback, capture, duplex). The new callback looks like the following:
-
- void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
-
- This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In playback-only mode, pInput will be
- null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer returned from the callback since it's not necessary for miniaudio
- anymore.
-
-2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client to choose a different PCM format
- for the playback and capture sides. The old ma_device_config object simply did not allow this and needed to change. With these changes you now specify the
- device ID, format, channels, channel map and share mode on a per-playback and per-capture basis (see example below). The sample rate must be the same for
- playback and capture.
-
- Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now, the device ID, device type and
- callback user data are set in the config. ma_device_init() is now simplified down to taking just the context, device config and a pointer to the device
- object being initialized. The rationale for this change is that it just makes more sense to me that these are set as part of the config like everything
- else.
-
- Example device initialization:
-
- ma_device_config config = ma_device_config_init(ma_device_type_duplex); // Or ma_device_type_playback or ma_device_type_capture.
- config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device.
- config.playback.format = ma_format_f32;
- config.playback.channels = 2;
- config.capture.pDeviceID = &myCaptureDeviceID; // Or NULL for the default capture device.
- config.capture.format = ma_format_s16;
- config.capture.channels = 1;
- config.sampleRate = 44100;
- config.dataCallback = data_callback;
- config.pUserData = &myUserData;
-
- result = ma_device_init(&myContext, &config, &device);
- if (result != MA_SUCCESS) {
- ... handle error ...
- }
-
- Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has been renamed to "stopCallback".
-
-This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample rate conversion is required for
-the playback device:
- - Core Audio
- - JACK
- - AAudio
- - OpenSL
- - WebAudio
-
-In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such thorough testing. If you
-experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample program that reproduces the issue if possible).
-
-
-Other API Changes
------------------
-In addition to the above, the following API changes have been made:
-
-- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization.
-- The onLogCallback member of ma_context_config has been renamed to "logCallback".
-- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
- - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it.
-- Some APIs have been renamed:
- - mal_decoder_read() -> ma_decoder_read_pcm_frames()
- - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
- - mal_sine_wave_read() -> ma_sine_wave_read_f32()
- - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
-- Some APIs have been removed:
- - mal_device_get_buffer_size_in_bytes()
- - mal_device_set_recv_callback()
- - mal_device_set_send_callback()
- - mal_src_set_input_sample_rate()
- - mal_src_set_output_sample_rate()
-- Error codes have been rearranged. If you're a binding maintainer you will need to update.
-- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection and to make it easier to see
- the priority. If you're a binding maintainer you will need to update.
-- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with some future planned high-level
- APIs.
-- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that the pointer comes before the
- count. The rationale for this is to keep it consistent with things like memcpy().
-
-
-Miscellaneous Changes
----------------------
-The following miscellaneous changes have also been made.
-
-- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the record, this is one of the nicest
- audio APIs out there, just behind the BSD audio APIs).
-- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL.
-- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio was not explicitly
- supported. These are no longer needed and have therefore been removed.
-- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an exclusive mode device, or an
- error. The rationale for this change is to give the client more control over how to handle cases when the desired shared mode is unavailable.
-- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb" operates on PCM frames.
-- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but removes the attribution
- requirement. The rationale for this is to support countries that don't recognize public domain.

-
-v0.10.9 - 2020-06-24
- - Amalgamation of dr_wav, dr_flac and dr_mp3. With this change, including the header section of these libraries before the implementation of miniaudio is no
- longer required. Decoding of WAV, FLAC and MP3 should be supported seamlessly without any additional libraries. Decoders can be excluded from the build
- with the following options:
- - MA_NO_WAV
- - MA_NO_FLAC
- - MA_NO_MP3
- If you get errors about multiple definitions you need to either enable the options above, move the implementation of dr_wav, dr_flac and/or dr_mp3 to before

- - Change playback.pDeviceID and capture.pDeviceID to constant pointers in ma_device_config.
- - Add support for initializing decoders from a virtual file system object. This is achieved via the ma_vfs API and allows the application to customize file
- IO for the loading and reading of raw audio data. Passing in NULL for the VFS will use defaults. New APIs:
- - ma_decoder_init_vfs()
- - ma_decoder_init_vfs_wav()
- - ma_decoder_init_vfs_flac()

- - ma_get_default_buffer_size_in_milliseconds()
- - ma_get_default_buffer_size_in_frames()
- - API CHANGE: ma_device_set_stop_callback() has been removed. If you require a stop callback, you must now set it via the device config just like the data

- - Core Audio: Fix bugs with automatic stream routing.
- - Add support for controlling whether or not the content of the output buffer passed in to the data callback is pre-initialized
- to zero. By default it will be initialized to zero, but this can be changed by setting noPreZeroedOutputBuffer in the device
- config. Setting noPreZeroedOutputBuffer to true will leave the contents undefined.
- - Add support for clipping samples after the data callback has returned. This only applies when the playback sample format is
- configured as ma_format_f32. If you are doing clipping yourself, you can disable this overhead by setting noClip to true in
- the device config.
- - Add support for master volume control for devices.
- - Use ma_device_set_master_volume() to set the volume to a factor between 0 and 1, where 0 is silence and 1 is full volume.

- Microsoft compilers back to VC6. Other compilers should also work, but have not been tested.
-
-v0.9.3 - 2019-04-19

- - Fix an issue where the data callback is getting called too frequently on the WASAPI and DirectSound backends.
- - Fix error on the UWP build.
- - Fix a build error on Apple platforms.
-
-v0.9 - 2019-03-06
- - Rebranded to "miniaudio". All namespaces have been renamed from "mal" to "ma".
- - API CHANGE: ma_device_init() and ma_device_config_init() have changed significantly:
- - The device type, device ID and user data pointer have moved from ma_device_init() to the config.
- - All variations of ma_device_config_init_*() have been removed in favor of just ma_device_config_init().
- - ma_device_config_init() now takes only one parameter which is the device type. All other properties need
- to be set on the returned object directly.
- - The onDataCallback and onStopCallback members of ma_device_config have been renamed to "dataCallback"
- and "stopCallback".
- - The ID of the physical device is now split into two: one for the playback device and the other for the
- capture device. This is required for full-duplex. These are named "pPlaybackDeviceID" and "pCaptureDeviceID".
- - API CHANGE: The data callback has changed. It now uses a unified callback for all device types rather than
- being separate for each. It now takes two pointers - one containing input data and the other output data. This
- design in required for full-duplex. The return value is now void instead of the number of frames written. The
- new callback looks like the following:
- void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
- - API CHANGE: Remove the log callback parameter from ma_context_config_init(). With this change,
- ma_context_config_init() now takes no parameters and the log callback is set via the structure directly. The
- new policy for config initialization is that only mandatory settings are passed in to *_config_init(). The
- "onLog" member of ma_context_config has been renamed to "logCallback".
- - API CHANGE: Remove ma_device_get_buffer_size_in_bytes().
- - API CHANGE: Rename decoding APIs to "pcm_frames" convention.
- - mal_decoder_read() -> ma_decoder_read_pcm_frames()
- - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
- - API CHANGE: Rename sine wave reading APIs to f32 convention.
- - mal_sine_wave_read() -> ma_sine_wave_read_f32()
- - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
- - API CHANGE: Remove some deprecated APIs
- - mal_device_set_recv_callback()
- - mal_device_set_send_callback()
- - mal_src_set_input_sample_rate()
- - mal_src_set_output_sample_rate()
- - API CHANGE: Add log level to the log callback. New signature:
- - void on_log(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
- - API CHANGE: Changes to result codes. Constants have changed and unused codes have been removed. If you're
- a binding mainainer you will need to update your result code constants.
- - API CHANGE: Change the order of the ma_backend enums to priority order. If you are a binding maintainer, you
- will need to update.
- - API CHANGE: Rename mal_dsp to ma_pcm_converter. All functions have been renamed from mal_dsp_*() to
- ma_pcm_converter_*(). All structures have been renamed from mal_dsp* to ma_pcm_converter*.
- - API CHANGE: Reorder parameters of ma_decoder_read_pcm_frames() to be consistent with the new parameter order scheme.
- - The resampling algorithm has been changed from sinc to linear. The rationale for this is that the sinc implementation
- is too inefficient right now. This will hopefully be improved at a later date.
- - Device initialization will no longer fall back to shared mode if exclusive mode is requested but is unusable.
- With this change, if you request an device in exclusive mode, but exclusive mode is not supported, it will not
- automatically fall back to shared mode. The client will need to reinitialize the device in shared mode if that's
- what they want.
- - Add ring buffer API. This is ma_rb and ma_pcm_rb, the difference being that ma_rb operates on bytes and
- ma_pcm_rb operates on PCM frames.
- - Add Web Audio backend. This is used when compiling with Emscripten. The SDL backend, which was previously
- used for web support, will be removed in a future version.
- - Add AAudio backend (Android Audio). This is the new priority backend for Android. Support for AAudio starts
- with Android 8. OpenSL|ES is used as a fallback for older versions of Android.
- - Remove OpenAL and SDL backends.
- - Fix a possible deadlock when rapidly stopping the device after it has started.
- - Update documentation.
- - Change licensing to a choice of public domain _or_ MIT-0 (No Attribution).

- - Fix a bug with UWP detection.
-
-v0.8.6 - 2018-08-26
- - Automatically switch the internal device when the default device is unplugged. Note that this is still in the
- early stages and not all backends handle this the same way. As of this version, this will not detect a default
- device switch when changed from the operating system's audio preferences (unless the backend itself handles
- this automatically). This is not supported in exclusive mode.
- - WASAPI and Core Audio: Add support for stream routing. When the application is using a default device and the
- user switches the default device via the operating system's audio preferences, miniaudio will automatically switch
- the internal device to the new default. This is not supported in exclusive mode.
- - WASAPI: Add support for hardware offloading via IAudioClient2. Only supported on Windows 8 and newer.
- - WASAPI: Add support for low-latency shared mode via IAudioClient3. Only supported on Windows 10 and newer.
- - Add support for compiling the UWP build as C.
- - mal_device_set_recv_callback() and mal_device_set_send_callback() have been deprecated. You must now set this
- when the device is initialized with mal_device_init*(). These will be removed in version 0.9.0.
-
-v0.8.5 - 2018-08-12
- - Add support for specifying the size of a device's buffer in milliseconds. You can still set the buffer size in
- frames if that suits you. When bufferSizeInFrames is 0, bufferSizeInMilliseconds will be used. If both are non-0
- then bufferSizeInFrames will take priority. If both are set to 0 the default buffer size is used.
- - Add support for the audio(4) backend to OpenBSD.
- - Fix a bug with the ALSA backend that was causing problems on Raspberry Pi. This significantly improves the
- Raspberry Pi experience.
- - Fix a bug where an incorrect number of samples is returned from sinc resampling.

- - Add audio(4) backend for NetBSD.
- - Drop support for the OSS backend on everything except FreeBSD and DragonFly BSD.
- - Formats are now native-endian (were previously little-endian).

- - mal_dsp_set_input_sample_rate() and mal_dsp_set_output_sample_rate() are replaced with mal_dsp_set_sample_rate().
- - Fix a bug when capturing using the WASAPI backend.
- - Fix some aliasing issues with resampling, specifically when increasing the sample rate.
- - Fix warnings.
-
-v0.8.3 - 2018-07-15
- - Fix a crackling bug when resampling in capture mode.
- - Core Audio: Fix a bug where capture does not work.
- - ALSA: Fix a bug where the worker thread can get stuck in an infinite loop.
- - PulseAudio: Fix a bug where mal_context_init() succeeds when PulseAudio is unusable.
- - JACK: Fix a bug where mal_context_init() succeeds when JACK is unusable.
-
-v0.8.2 - 2018-07-07
- - Fix a bug on macOS with Core Audio where the internal callback is not called.
-
-v0.8.1 - 2018-07-06
- - Fix compilation errors and warnings.
-
-v0.8 - 2018-07-05
- - Changed MAL_IMPLEMENTATION to MINI_AL_IMPLEMENTATION for consistency with other libraries. The old
- way is still supported for now, but you should update as it may be removed in the future.
- - API CHANGE: Replace device enumeration APIs. mal_enumerate_devices() has been replaced with
- mal_context_get_devices(). An additional low-level device enumration API has been introduced called
- mal_context_enumerate_devices() which uses a callback to report devices.
- - API CHANGE: Rename mal_get_sample_size_in_bytes() to mal_get_bytes_per_sample() and add
- mal_get_bytes_per_frame().
- - API CHANGE: Replace mal_device_config.preferExclusiveMode with mal_device_config.shareMode.
- - This new config can be set to mal_share_mode_shared (default) or mal_share_mode_exclusive.
- - API CHANGE: Remove excludeNullDevice from mal_context_config.alsa.
- - API CHANGE: Rename MAL_MAX_SAMPLE_SIZE_IN_BYTES to MAL_MAX_PCM_SAMPLE_SIZE_IN_BYTES.
- - API CHANGE: Change the default channel mapping to the standard Microsoft mapping.
- - API CHANGE: Remove backend-specific result codes.
- - API CHANGE: Changes to the format conversion APIs (mal_pcm_f32_to_s16(), etc.)
- - Add support for Core Audio (Apple).
- - Add support for PulseAudio.
- - This is the highest priority backend on Linux (higher priority than ALSA) since it is commonly
- installed by default on many of the popular distros and offer's more seamless integration on
- platforms where PulseAudio is used. In addition, if PulseAudio is installed and running (which
- is extremely common), it's better to just use PulseAudio directly rather than going through the
- "pulse" ALSA plugin (which is what the "default" ALSA device is likely set to).
- - Add support for JACK.
- - Remove dependency on asound.h for the ALSA backend. This means the ALSA development packages are no
- longer required to build miniaudio.
- - Remove dependency on dsound.h for the DirectSound backend. This fixes build issues with some
- distributions of MinGW.
- - Remove dependency on audioclient.h for the WASAPI backend. This fixes build issues with some
- distributions of MinGW.
- - Add support for dithering to format conversion.
- - Add support for configuring the priority of the worker thread.
- - Add a sine wave generator.
- - Improve efficiency of sample rate conversion.
- - Introduce the notion of standard channel maps. Use mal_get_standard_channel_map().
- - Introduce the notion of default device configurations. A default config uses the same configuration
- as the backend's internal device, and as such results in a pass-through data transmission pipeline.
- - Add support for passing in NULL for the device config in mal_device_init(), which uses a default
- config. This requires manually calling mal_device_set_send/recv_callback().
- - Add support for decoding from raw PCM data (mal_decoder_init_raw(), etc.)
- - Make mal_device_init_ex() more robust.
- - Make some APIs more const-correct.
- - Fix errors with SDL detection on Apple platforms.
- - Fix errors with OpenAL detection.
- - Fix some memory leaks.
- - Fix a bug with opening decoders from memory.
- - Early work on SSE2, AVX2 and NEON optimizations.
- - Miscellaneous bug fixes.
- - Documentation updates.
-
-v0.7 - 2018-02-25
- - API CHANGE: Change mal_src_read_frames() and mal_dsp_read_frames() to use 64-bit sample counts.
- - Add decoder APIs for loading WAV, FLAC, Vorbis and MP3 files.
- - Allow opening of devices without a context.
- - In this case the context is created and managed internally by the device.
- - Change the default channel mapping to the same as that used by FLAC.
- - Fix build errors with macOS.
-
-v0.6c - 2018-02-12
- - Fix build errors with BSD/OSS.
-
-v0.6b - 2018-02-03
- - Fix some warnings when compiling with Visual C++.
-
-v0.6a - 2018-01-26
- - Fix errors with channel mixing when increasing the channel count.
- - Improvements to the build system for the OpenAL backend.
- - Documentation fixes.
-
-v0.6 - 2017-12-08
- - API CHANGE: Expose and improve mutex APIs. If you were using the mutex APIs before this version you'll
- need to update.
- - API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively.
- - API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent.
- - Add support for SDL and Emscripten.
- - Simplify the build system further for when development packages for various backends are not installed.
- With this change, when the compiler supports __has_include, backends without the relevant development
- packages installed will be ignored. This fixes the build for old versions of MinGW.
- - Fixes to the Android build.
- - Add mal_convert_frames(). This is a high-level helper API for performing a one-time, bulk conversion of
- audio data to a different format.
- - Improvements to f32 -> u8/s16/s24/s32 conversion routines.
- - Fix a bug where the wrong value is returned from mal_device_start() for the OpenSL backend.
- - Fixes and improvements for Raspberry Pi.
- - Warning fixes.
-
-v0.5 - 2017-11-11
- - API CHANGE: The mal_context_init() function now takes a pointer to a mal_context_config object for
- configuring the context. The works in the same kind of way as the device config. The rationale for this
- change is to give applications better control over context-level properties, add support for backend-
- specific configurations, and support extensibility without breaking the API.
- - API CHANGE: The alsa.preferPlugHW device config variable has been removed since it's not really useful for
- anything anymore.
- - ALSA: By default, device enumeration will now only enumerate over unique card/device pairs. Applications
- can enable verbose device enumeration by setting the alsa.useVerboseDeviceEnumeration context config
- variable.
- - ALSA: When opening a device in shared mode (the default), the dmix/dsnoop plugin will be prioritized. If
- this fails it will fall back to the hw plugin. With this change the preferExclusiveMode config is now
- honored. Note that this does not happen when alsa.useVerboseDeviceEnumeration is set to true (see above)
- which is by design.
- - ALSA: Add support for excluding the "null" device using the alsa.excludeNullDevice context config variable.
- - ALSA: Fix a bug with channel mapping which causes an assertion to fail.
- - Fix errors with enumeration when pInfo is set to NULL.
- - OSS: Fix a bug when starting a device when the client sends 0 samples for the initial buffer fill.
-
-v0.4 - 2017-11-05
- - API CHANGE: The log callback is now per-context rather than per-device and as is thus now passed to
- mal_context_init(). The rationale for this change is that it allows applications to capture diagnostic
- messages at the context level. Previously this was only available at the device level.
- - API CHANGE: The device config passed to mal_device_init() is now const.
- - Added support for OSS which enables support on BSD platforms.
- - Added support for WinMM (waveOut/waveIn).
- - Added support for UWP (Universal Windows Platform) applications. Currently C++ only.
- - Added support for exclusive mode for selected backends. Currently supported on WASAPI.
- - POSIX builds no longer require explicit linking to libpthread (-lpthread).
- - ALSA: Explicit linking to libasound (-lasound) is no longer required.
- - ALSA: Latency improvements.
- - ALSA: Use MMAP mode where available. This can be disabled with the alsa.noMMap config.
- - ALSA: Use "hw" devices instead of "plughw" devices by default. This can be disabled with the
- alsa.preferPlugHW config.
- - WASAPI is now the highest priority backend on Windows platforms.
- - Fixed an error with sample rate conversion which was causing crackling when capturing.
- - Improved error handling.
- - Improved compiler support.
- - Miscellaneous bug fixes.
-
-v0.3 - 2017-06-19
- - API CHANGE: Introduced the notion of a context. The context is the highest level object and is required for
- enumerating and creating devices. Now, applications must first create a context, and then use that to
- enumerate and create devices. The reason for this change is to ensure device enumeration and creation is
- tied to the same backend. In addition, some backends are better suited to this design.
- - API CHANGE: Removed the rewinding APIs because they're too inconsistent across the different backends, hard
- to test and maintain, and just generally unreliable.
- - Added helper APIs for initializing mal_device_config objects.
- - Null Backend: Fixed a crash when recording.
- - Fixed build for UWP.
- - Added support for f32 formats to the OpenSL|ES backend.
- - Added initial implementation of the WASAPI backend.
- - Added initial implementation of the OpenAL backend.
- - Added support for low quality linear sample rate conversion.
- - Added early support for basic channel mapping.
-
-v0.2 - 2016-10-28
- - API CHANGE: Add user data pointer as the last parameter to mal_device_init(). The rationale for this
- change is to ensure the logging callback has access to the user data during initialization.
- - API CHANGE: Have device configuration properties be passed to mal_device_init() via a structure. Rationale:
- 1) The number of parameters is just getting too much.
- 2) It makes it a bit easier to add new configuration properties in the future. In particular, there's a
- chance there will be support added for backend-specific properties.
- - Dropped support for f64, A-law and Mu-law formats since they just aren't common enough to justify the
- added maintenance cost.
- - DirectSound: Increased the default buffer size for capture devices.
- - Added initial implementation of the OpenSL|ES backend.
-
-v0.1 - 2016-10-21
- - Initial versioned release.

-HOW TO USE:
-
- In exactly one translation unit (.c or .cpp file), #define MSF_GIF_IMPL before including the header, like so:
-
- #define MSF_GIF_IMPL
- #include "msf_gif.h"
-
- Everywhere else, just include the header like normal.
-
-
-USAGE EXAMPLE:
-
- int width = 480, height = 320, centisecondsPerFrame = 5, bitDepth = 16;
- MsfGifState gifState = {};
- msf_gif_begin(&gifState, width, height);
- msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 1
- msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 2
- msf_gif_frame(&gifState, ..., centisecondsPerFrame, bitDepth, width * 4); //frame 3, etc...
- MsfGifResult result = msf_gif_end(&gifState);
- FILE * fp = fopen("MyGif.gif", "wb");
- fwrite(result.data, result.dataSize, 1, fp);
- fclose(fp);
- msf_gif_free(result);
-
-Detailed function documentation can be found in the header section below.
-
-
-REPLACING MALLOC:
-
- This library uses malloc+realloc+free internally for memory allocation.
- To facilitate integration with custom memory allocators, these calls go through macros, which can be redefined.
- The expected function signature equivalents of the macros are as follows:
-
- void * MSF_GIF_MALLOC(void * context, size_t newSize)
- void * MSF_GIF_REALLOC(void * context, void * oldMemory, size_t oldSize, size_t newSize)
- void MSF_GIF_FREE(void * context, void * oldMemory, size_t oldSize)
-
- If your allocator needs a context pointer, you can set the `customAllocatorContext` field of the MsfGifState struct
- before calling msf_gif_begin(), and it will be passed to all subsequent allocator macro calls.
-
-See end of file for license information.

-// SHAPES :: https://github.com/prideout/par
-// Simple C library for creation and manipulation of triangle meshes.
-//
-// The API is divided into three sections:
-//
-// - Generators. Create parametric surfaces, platonic solids, etc.
-// - Queries. Ask a mesh for its axis-aligned bounding box, etc.
-// - Transforms. Rotate a mesh, merge it with another, add normals, etc.
-//
-// In addition to the comment block above each function declaration, the API
-// has informal documentation here:
-//
-// https://prideout.net/shapes
-//
-// For our purposes, a "mesh" is a list of points and a list of triangles; the
-// former is a flattened list of three-tuples (32-bit floats) and the latter is
-// also a flattened list of three-tuples (16-bit uints). Triangles are always
-// oriented such that their front face winds counter-clockwise.
-//
-// Optionally, meshes can contain 3D normals (one per vertex), and 2D texture
-// coordinates (one per vertex). That's it! If you need something fancier,
-// look elsewhere.

-# Small Deflate
-`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
-which implements the Deflate (RFC 1951) compressed data format specification standard.
-It is mainly tuned to get as much speed and compression ratio from as little code
-as needed to keep the implementation as concise as possible.
-
-## Features
-- Portable single header and source file duo written in ANSI C (ISO C90)
-- Dual license with either MIT or public domain
-- Small implementation
- - Deflate: 525 LoC
- - Inflate: 320 LoC
-- Webassembly:
- - Deflate ~3.7 KB (~2.2KB compressed)
- - Inflate ~3.6 KB (~2.2KB compressed)
-
-## Usage:
-This file behaves differently depending on what symbols you define
-before including it.
-
-Header-File mode:
-If you do not define `SDEFL_IMPLEMENTATION` before including this file, it
-will operate in header only mode. In this mode it declares all used structs
-and the API of the library without including the implementation of the library.
-
-Implementation mode:
-If you define `SDEFL_IMPLEMENTATION` before including this file, it will
-compile the implementation . Make sure that you only include
-this file implementation in *one* C or C++ file to prevent collisions.

-# Small Deflate
-`sdefl` is a small bare bone lossless compression library in ANSI C (ISO C90)
-which implements the Deflate (RFC 1951) compressed data format specification standard.
-It is mainly tuned to get as much speed and compression ratio from as little code
-as needed to keep the implementation as concise as possible.
-
-## Features
-- Portable single header and source file duo written in ANSI C (ISO C90)
-- Dual license with either MIT or public domain
-- Small implementation
- - Deflate: 525 LoC
- - Inflate: 320 LoC
-- Webassembly:
- - Deflate ~3.7 KB (~2.2KB compressed)
- - Inflate ~3.6 KB (~2.2KB compressed)
-
-## Usage:
-This file behaves differently depending on what symbols you define
-before including it.
-
-Header-File mode:
-If you do not define `SINFL_IMPLEMENTATION` before including this file, it
-will operate in header only mode. In this mode it declares all used structs
-and the API of the library without including the implementation of the library.
-
-Implementation mode:
-If you define `SINFL_IMPLEMENTATION` before including this file, it will
-compile the implementation. Make sure that you only include
-this file implementation in *one* C or C++ file to prevent collisions.

-
-// DOCUMENTATION
-//
-// Limitations:
-// - no 12-bit-per-channel JPEG
-// - no JPEGs with arithmetic coding
-// - GIF always returns *comp=4
-//
-// Basic usage (see HDR discussion below for HDR usage):
-// int x,y,n;
-// unsigned char *data = stbi_load(filename, &x, &y, &n, 0);
-// // ... process data if not NULL ...
-// // ... x = width, y = height, n = # 8-bit components per pixel ...
-// // ... replace '0' with '1'..'4' to force that many components per pixel
-// // ... but 'n' will always be the number that it would have been if you said 0
-// stbi_image_free(data)
-//
-// Standard parameters:
-// int *x -- outputs image width in pixels
-// int *y -- outputs image height in pixels
-// int *channels_in_file -- outputs # of image components in image file
-// int desired_channels -- if non-zero, # of image components requested in result
-//
-// The return value from an image loader is an 'unsigned char *' which points
-// to the pixel data, or NULL on an allocation failure or if the image is
-// corrupt or invalid. The pixel data consists of *y scanlines of *x pixels,
-// with each pixel consisting of N interleaved 8-bit components; the first
-// pixel pointed to is top-left-most in the image. There is no padding between
-// image scanlines or between pixels, regardless of format. The number of
-// components N is 'desired_channels' if desired_channels is non-zero, or
-// *channels_in_file otherwise. If desired_channels is non-zero,
-// *channels_in_file has the number of components that _would_ have been
-// output otherwise. E.g. if you set desired_channels to 4, you will always
-// get RGBA output, but you can check *channels_in_file to see if it's trivially
-// opaque because e.g. there were only 3 channels in the source image.
-//
-// An output image with N components has the following components interleaved
-// in this order in each pixel:
-//
-// N=#comp components
-// 1 grey
-// 2 grey, alpha
-// 3 red, green, blue
-// 4 red, green, blue, alpha
-//
-// If image loading fails for any reason, the return value will be NULL,
-// and *x, *y, *channels_in_file will be unchanged. The function
-// stbi_failure_reason() can be queried for an extremely brief, end-user
-// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS
-// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly
-// more user-friendly ones.
-//
-// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized.
-//
-// ===========================================================================
-//
-// UNICODE:
-//
-// If compiling for Windows and you wish to use Unicode filenames, compile
-// with
-// #define STBI_WINDOWS_UTF8
-// and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert
-// Windows wchar_t filenames to utf8.
-//
-// ===========================================================================
-//
-// Philosophy
-//
-// stb libraries are designed with the following priorities:
-//
-// 1. easy to use
-// 2. easy to maintain
-// 3. good performance
-//
-// Sometimes I let "good performance" creep up in priority over "easy to maintain",
-// and for best performance I may provide less-easy-to-use APIs that give higher
-// performance, in addition to the easy-to-use ones. Nevertheless, it's important
-// to keep in mind that from the standpoint of you, a client of this library,
-// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all.
-//
-// Some secondary priorities arise directly from the first two, some of which
-// provide more explicit reasons why performance can't be emphasized.
-//
-// - Portable ("ease of use")
-// - Small source code footprint ("easy to maintain")
-// - No dependencies ("ease of use")
-//
-// ===========================================================================
-//
-// I/O callbacks
-//
-// I/O callbacks allow you to read from arbitrary sources, like packaged
-// files or some other source. Data read from callbacks are processed
-// through a small internal buffer (currently 128 bytes) to try to reduce
-// overhead.
-//
-// The three functions you must define are "read" (reads some bytes of data),
-// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end).
-//
-// ===========================================================================
-//
-// SIMD support
-//
-// The JPEG decoder will try to automatically use SIMD kernels on x86 when
-// supported by the compiler. For ARM Neon support, you must explicitly
-// request it.
-//
-// (The old do-it-yourself SIMD API is no longer supported in the current
-// code.)
-//
-// On x86, SSE2 will automatically be used when available based on a run-time
-// test; if not, the generic C versions are used as a fall-back. On ARM targets,
-// the typical path is to have separate builds for NEON and non-NEON devices
-// (at least this is true for iOS and Android). Therefore, the NEON support is
-// toggled by a build flag: define STBI_NEON to get NEON loops.
-//
-// If for some reason you do not want to use any of SIMD code, or if
-// you have issues compiling it, you can disable it entirely by
-// defining STBI_NO_SIMD.
-//
-// ===========================================================================
-//
-// HDR image support (disable by defining STBI_NO_HDR)
-//
-// stb_image supports loading HDR images in general, and currently the Radiance
-// .HDR file format specifically. You can still load any file through the existing
-// interface; if you attempt to load an HDR file, it will be automatically remapped
-// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;
-// both of these constants can be reconfigured through this interface:
-//
-// stbi_hdr_to_ldr_gamma(2.2f);
-// stbi_hdr_to_ldr_scale(1.0f);
-//
-// (note, do not use _inverse_ constants; stbi_image will invert them
-// appropriately).
-//
-// Additionally, there is a new, parallel interface for loading files as
-// (linear) floats to preserve the full dynamic range:
-//
-// float *data = stbi_loadf(filename, &x, &y, &n, 0);
-//
-// If you load LDR images through this interface, those images will
-// be promoted to floating point values, run through the inverse of
-// constants corresponding to the above:
-//
-// stbi_ldr_to_hdr_scale(1.0f);
-// stbi_ldr_to_hdr_gamma(2.2f);
-//
-// Finally, given a filename (or an open file or memory block--see header
-// file for details) containing image data, you can query for the "most
-// appropriate" interface to use (that is, whether the image is HDR or
-// not), using:
-//
-// stbi_is_hdr(char *filename);
-//
-// ===========================================================================
-//
-// iPhone PNG support:
-//
-// By default we convert iphone-formatted PNGs back to RGB, even though
-// they are internally encoded differently. You can disable this conversion
-// by calling stbi_convert_iphone_png_to_rgb(0), in which case
-// you will always just get the native iphone "format" through (which
-// is BGR stored in RGB).
-//
-// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per
-// pixel to remove any premultiplied alpha *only* if the image file explicitly
-// says there's premultiplied data (currently only happens in iPhone images,
-// and only if iPhone convert-to-rgb processing is on).
-//
-// ===========================================================================
-//
-// ADDITIONAL CONFIGURATION
-//
-// - You can suppress implementation of any of the decoders to reduce
-// your code footprint by #defining one or more of the following
-// symbols before creating the implementation.
-//
-// STBI_NO_JPEG
-// STBI_NO_PNG
-// STBI_NO_BMP
-// STBI_NO_PSD
-// STBI_NO_TGA
-// STBI_NO_GIF
-// STBI_NO_HDR
-// STBI_NO_PIC
-// STBI_NO_PNM (.ppm and .pgm)
-//
-// - You can request *only* certain decoders and suppress all other ones
-// (this will be more forward-compatible, as addition of new decoders
-// doesn't require you to disable them explicitly):
-//
-// STBI_ONLY_JPEG
-// STBI_ONLY_PNG
-// STBI_ONLY_BMP
-// STBI_ONLY_PSD
-// STBI_ONLY_TGA
-// STBI_ONLY_GIF
-// STBI_ONLY_HDR
-// STBI_ONLY_PIC
-// STBI_ONLY_PNM (.ppm and .pgm)
-//
-// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still
-// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB
-//
-// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater
-// than that size (in either width or height) without further processing.
-// This is to let programs in the wild set an upper bound to prevent
-// denial-of-service attacks on untrusted data, as one could generate a
-// valid image of gigantic dimensions and force stb_image to allocate a
-// huge block of memory and spend disproportionate time decoding it. By
-// default this is set to (1 << 24), which is 16777216, but that's still
-// very big.

-/* stb_image_resize - v0.96 - public domain image resizing
- by Jorge L Rodriguez (@VinoBS) - 2014
- http://github.com/nothings/stb
-
- Written with emphasis on usability, portability, and efficiency. (No
- SIMD or threads, so it be easily outperformed by libs that use those.)
- Only scaling and translation is supported, no rotations or shears.
- Easy API downsamples w/Mitchell filter, upsamples w/cubic interpolation.
-
- COMPILING & LINKING
- In one C/C++ file that #includes this file, do this:
- #define STB_IMAGE_RESIZE_IMPLEMENTATION
- before the #include. That will create the implementation in that file.
-
- QUICKSTART
- stbir_resize_uint8( input_pixels , in_w , in_h , 0,
- output_pixels, out_w, out_h, 0, num_channels)
- stbir_resize_float(...)
- stbir_resize_uint8_srgb( input_pixels , in_w , in_h , 0,
- output_pixels, out_w, out_h, 0,
- num_channels , alpha_chan , 0)
- stbir_resize_uint8_srgb_edgemode(
- input_pixels , in_w , in_h , 0,
- output_pixels, out_w, out_h, 0,
- num_channels , alpha_chan , 0, STBIR_EDGE_CLAMP)
- // WRAP/REFLECT/ZERO
-
- FULL API
- See the "header file" section of the source for API documentation.
-
- ADDITIONAL DOCUMENTATION
-
- SRGB & FLOATING POINT REPRESENTATION
- The sRGB functions presume IEEE floating point. If you do not have
- IEEE floating point, define STBIR_NON_IEEE_FLOAT. This will use
- a slower implementation.
-
- MEMORY ALLOCATION
- The resize functions here perform a single memory allocation using
- malloc. To control the memory allocation, before the #include that
- triggers the implementation, do:
-
- #define STBIR_MALLOC(size,context) ...
- #define STBIR_FREE(ptr,context) ...
-
- Each resize function makes exactly one call to malloc/free, so to use
- temp memory, store the temp memory in the context and return that.
-
- ASSERT
- Define STBIR_ASSERT(boolval) to override assert() and not use assert.h
-
- OPTIMIZATION
- Define STBIR_SATURATE_INT to compute clamp values in-range using
- integer operations instead of float operations. This may be faster
- on some platforms.
-
- DEFAULT FILTERS
- For functions which don't provide explicit control over what filters
- to use, you can change the compile-time defaults with
-
- #define STBIR_DEFAULT_FILTER_UPSAMPLE STBIR_FILTER_something
- #define STBIR_DEFAULT_FILTER_DOWNSAMPLE STBIR_FILTER_something
-
- See stbir_filter in the header-file section for the list of filters.
-
- NEW FILTERS
- A number of 1D filter kernels are used. For a list of
- supported filters see the stbir_filter enum. To add a new filter,
- write a filter function and add it to stbir__filter_info_table.
-
- PROGRESS
- For interactive use with slow resize operations, you can install
- a progress-report callback:
-
- #define STBIR_PROGRESS_REPORT(val) some_func(val)
-
- The parameter val is a float which goes from 0 to 1 as progress is made.
-
- For example:
-
- static void my_progress_report(float progress);
- #define STBIR_PROGRESS_REPORT(val) my_progress_report(val)
-
- #define STB_IMAGE_RESIZE_IMPLEMENTATION
- #include "stb_image_resize.h"
-
- static void my_progress_report(float progress)
- {
- printf("Progress: %f%%\n", progress*100);
- }
-
- MAX CHANNELS
- If your image has more than 64 channels, define STBIR_MAX_CHANNELS
- to the max you'll have.
-
- ALPHA CHANNEL
- Most of the resizing functions provide the ability to control how
- the alpha channel of an image is processed. The important things
- to know about this:
-
- 1. The best mathematically-behaved version of alpha to use is
- called "premultiplied alpha", in which the other color channels
- have had the alpha value multiplied in. If you use premultiplied
- alpha, linear filtering (such as image resampling done by this
- library, or performed in texture units on GPUs) does the "right
- thing". While premultiplied alpha is standard in the movie CGI
- industry, it is still uncommon in the videogame/real-time world.
-
- If you linearly filter non-premultiplied alpha, strange effects
- occur. (For example, the 50/50 average of 99% transparent bright green
- and 1% transparent black produces 50% transparent dark green when
- non-premultiplied, whereas premultiplied it produces 50%
- transparent near-black. The former introduces green energy
- that doesn't exist in the source image.)
-
- 2. Artists should not edit premultiplied-alpha images; artists
- want non-premultiplied alpha images. Thus, art tools generally output
- non-premultiplied alpha images.
-
- 3. You will get best results in most cases by converting images
- to premultiplied alpha before processing them mathematically.
-
- 4. If you pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, the
- resizer does not do anything special for the alpha channel;
- it is resampled identically to other channels. This produces
- the correct results for premultiplied-alpha images, but produces
- less-than-ideal results for non-premultiplied-alpha images.
-
- 5. If you do not pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED,
- then the resizer weights the contribution of input pixels
- based on their alpha values, or, equivalently, it multiplies
- the alpha value into the color channels, resamples, then divides
- by the resultant alpha value. Input pixels which have alpha=0 do
- not contribute at all to output pixels unless _all_ of the input
- pixels affecting that output pixel have alpha=0, in which case
- the result for that pixel is the same as it would be without
- STBIR_FLAG_ALPHA_PREMULTIPLIED. However, this is only true for
- input images in integer formats. For input images in float format,
- input pixels with alpha=0 have no effect, and output pixels
- which have alpha=0 will be 0 in all channels. (For float images,
- you can manually achieve the same result by adding a tiny epsilon
- value to the alpha channel of every image, and then subtracting
- or clamping it at the end.)
-
- 6. You can suppress the behavior described in #5 and make
- all-0-alpha pixels have 0 in all channels by #defining
- STBIR_NO_ALPHA_EPSILON.
-
- 7. You can separately control whether the alpha channel is
- interpreted as linear or affected by the colorspace. By default
- it is linear; you almost never want to apply the colorspace.
- (For example, graphics hardware does not apply sRGB conversion
- to the alpha channel.)

-// * input_w is input image width (x-axis), input_h is input image height (y-axis)
-// * stride is the offset between successive rows of image data in memory, in bytes. you can
-// specify 0 to mean packed continuously in memory
-// * alpha channel is treated identically to other channels.
-// * colorspace is linear or sRGB as specified by function name
-// * returned result is 1 for success or 0 in case of an error.
-// #define STBIR_ASSERT() to trigger an assert on parameter validation errors.
-// * Memory required grows approximately linearly with input and output size, but with
-// discontinuities at input_w == output_w and input_h == output_h.
-// * These functions use a "default" resampling filter defined at compile time. To change the filter,
-// you can change the compile-time defaults by #defining STBIR_DEFAULT_FILTER_UPSAMPLE
-// and STBIR_DEFAULT_FILTER_DOWNSAMPLE, or you can use the medium-complexity API.

-/* stb_image_write - v1.15 - public domain - http://nothings.org/stb
- writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
- no warranty implied; use at your own risk
-
- Before #including,
-
- #define STB_IMAGE_WRITE_IMPLEMENTATION
-
- in the file that you want to have the implementation.
-
- Will probably not work correctly with strict-aliasing optimizations.
-
-ABOUT:
-
- This header file is a library for writing images to C stdio or a callback.
-
- The PNG output is not optimal; it is 20-50% larger than the file
- written by a decent optimizing implementation; though providing a custom
- zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that.
- This library is designed for source code compactness and simplicity,
- not optimal image file size or run-time performance.
-
-BUILDING:
-
- You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
- You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
- malloc,realloc,free.
- You can #define STBIW_MEMMOVE() to replace memmove()
- You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function
- for PNG compression (instead of the builtin one), it must have the following signature:
- unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality);
- The returned data will be freed with STBIW_FREE() (free() by default),
- so it must be heap allocated with STBIW_MALLOC() (malloc() by default),
-
-UNICODE:
-
- If compiling for Windows and you wish to use Unicode filenames, compile
- with
- #define STBIW_WINDOWS_UTF8
- and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert
- Windows wchar_t filenames to utf8.
-
-USAGE:
-
- There are five functions, one for each image file format:
-
- int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
- int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
- int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
- int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality);
- int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
-
- void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
-
- There are also five equivalent functions that use an arbitrary write function. You are
- expected to open/close your file-equivalent before and after calling these:
-
- int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes);
- int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
- int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
- int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
- int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
-
- where the callback is:
- void stbi_write_func(void *context, void *data, int size);
-
- You can configure it with these global variables:
- int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE
- int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression
- int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode
-
-
- You can define STBI_WRITE_NO_STDIO to disable the file variant of these
- functions, so the library will not use stdio.h at all. However, this will
- also disable HDR writing, because it requires stdio for formatted output.
-
- Each function returns 0 on failure and non-0 on success.
-
- The functions create an image file defined by the parameters. The image
- is a rectangle of pixels stored from left-to-right, top-to-bottom.
- Each pixel contains 'comp' channels of data stored interleaved with 8-bits
- per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
- monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
- The *data pointer points to the first byte of the top-left-most pixel.
- For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
- a row of pixels to the first byte of the next row of pixels.
-
- PNG creates output files with the same number of components as the input.
- The BMP format expands Y to RGB in the file format and does not
- output alpha.
-
- PNG supports writing rectangles of data even when the bytes storing rows of
- data are not consecutive in memory (e.g. sub-rectangles of a larger image),
- by supplying the stride between the beginning of adjacent rows. The other
- formats do not. (Thus you cannot write a native-format BMP through the BMP
- writer, both because it is in BGR order and because it may have padding
- at the end of the line.)
-
- PNG allows you to set the deflate compression level by setting the global
- variable 'stbi_write_png_compression_level' (it defaults to 8).
-
- HDR expects linear float data. Since the format is always 32-bit rgb(e)
- data, alpha (if provided) is discarded, and for monochrome data it is
- replicated across all three channels.
-
- TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
- data, set the global variable 'stbi_write_tga_with_rle' to 0.
-
- JPEG does ignore alpha channels in input data; quality is between 1 and 100.
- Higher quality looks better but results in a bigger image.
- JPEG baseline (no JPEG progressive).

-// stb_perlin.h - v0.5 - perlin noise
-// public domain single-file C implementation by Sean Barrett
-//
-// LICENSE
-//
-// See end of file.
-//
-//
-// to create the implementation,
-// #define STB_PERLIN_IMPLEMENTATION
-// in *one* C/CPP file that includes this file.
-//
-//
-// Documentation:
-//
-// float stb_perlin_noise3( float x,
-// float y,
-// float z,
-// int x_wrap=0,
-// int y_wrap=0,
-// int z_wrap=0)
-//
-// This function computes a random value at the coordinate (x,y,z).
-// Adjacent random values are continuous but the noise fluctuates
-// its randomness with period 1, i.e. takes on wholly unrelated values
-// at integer points. Specifically, this implements Ken Perlin's
-// revised noise function from 2002.
-//
-// The "wrap" parameters can be used to create wraparound noise that
-// wraps at powers of two. The numbers MUST be powers of two. Specify
-// 0 to mean "don't care". (The noise always wraps every 256 due
-// details of the implementation, even if you ask for larger or no
-// wrapping.)
-//
-// float stb_perlin_noise3_seed( float x,
-// float y,
-// float z,
-// int x_wrap=0,
-// int y_wrap=0,
-// int z_wrap=0,
-// int seed)
-//
-// As above, but 'seed' selects from multiple different variations of the
-// noise function. The current implementation only uses the bottom 8 bits
-// of 'seed', but possibly in the future more bits will be used.
-//
-//
-// Fractal Noise:
-//
-// Three common fractal noise functions are included, which produce
-// a wide variety of nice effects depending on the parameters
-// provided. Note that each function will call stb_perlin_noise3
-// 'octaves' times, so this parameter will affect runtime.
-//
-// float stb_perlin_ridge_noise3(float x, float y, float z,
-// float lacunarity, float gain, float offset, int octaves)
-//
-// float stb_perlin_fbm_noise3(float x, float y, float z,
-// float lacunarity, float gain, int octaves)
-//
-// float stb_perlin_turbulence_noise3(float x, float y, float z,
-// float lacunarity, float gain, int octaves)
-//
-// Typical values to start playing with:
-// octaves = 6 -- number of "octaves" of noise3() to sum
-// lacunarity = ~ 2.0 -- spacing between successive octaves (use exactly 2.0 for wrapping output)
-// gain = 0.5 -- relative weighting applied to each successive octave
-// offset = 1.0? -- used to invert the ridges, may need to be larger, not sure
-//
-//
-// Contributors:
-// Jack Mott - additional noise functions
-// Jordan Peck - seeded noise

-// stb_rect_pack.h - v1.00 - public domain - rectangle packing
-// Sean Barrett 2014
-//
-// Useful for e.g. packing rectangular textures into an atlas.
-// Does not do rotation.
-//
-// Not necessarily the awesomest packing method, but better than
-// the totally naive one in stb_truetype (which is primarily what
-// this is meant to replace).
-//
-// Has only had a few tests run, may have issues.
-//
-// More docs to come.
-//
-// No memory allocations; uses qsort() and assert() from stdlib.
-// Can override those by defining STBRP_SORT and STBRP_ASSERT.
-//
-// This library currently uses the Skyline Bottom-Left algorithm.
-//
-// Please note: better rectangle packers are welcome! Please
-// implement them to the same API, but with a different init
-// function.

-//
-// USAGE
-//
-// Include this file in whatever places need to refer to it. In ONE C/C++
-// file, write:
-// #define STB_TRUETYPE_IMPLEMENTATION
-// before the #include of this file. This expands out the actual
-// implementation into that C/C++ file.
-//
-// To make the implementation private to the file that generates the implementation,
-// #define STBTT_STATIC
-//
-// Simple 3D API (don't ship this, but it's fine for tools and quick start)
-// stbtt_BakeFontBitmap() -- bake a font to a bitmap for use as texture
-// stbtt_GetBakedQuad() -- compute quad to draw for a given char
-//
-// Improved 3D API (more shippable):
-// #include "stb_rect_pack.h" -- optional, but you really want it
-// stbtt_PackBegin()
-// stbtt_PackSetOversampling() -- for improved quality on small fonts
-// stbtt_PackFontRanges() -- pack and renders
-// stbtt_PackEnd()
-// stbtt_GetPackedQuad()
-//
-// "Load" a font file from a memory buffer (you have to keep the buffer loaded)
-// stbtt_InitFont()
-// stbtt_GetFontOffsetForIndex() -- indexing for TTC font collections
-// stbtt_GetNumberOfFonts() -- number of fonts for TTC font collections
-//
-// Render a unicode codepoint to a bitmap
-// stbtt_GetCodepointBitmap() -- allocates and returns a bitmap
-// stbtt_MakeCodepointBitmap() -- renders into bitmap you provide
-// stbtt_GetCodepointBitmapBox() -- how big the bitmap must be
-//
-// Character advance/positioning
-// stbtt_GetCodepointHMetrics()
-// stbtt_GetFontVMetrics()
-// stbtt_GetFontVMetricsOS2()
-// stbtt_GetCodepointKernAdvance()
-//
-// Starting with version 1.06, the rasterizer was replaced with a new,
-// faster and generally-more-precise rasterizer. The new rasterizer more
-// accurately measures pixel coverage for anti-aliasing, except in the case
-// where multiple shapes overlap, in which case it overestimates the AA pixel
-// coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
-// this turns out to be a problem, you can re-enable the old rasterizer with
-// #define STBTT_RASTERIZER_VERSION 1
-// which will incur about a 15% speed hit.
-//
-// ADDITIONAL DOCUMENTATION
-//
-// Immediately after this block comment are a series of sample programs.
-//
-// After the sample programs is the "header file" section. This section
-// includes documentation for each API function.
-//
-// Some important concepts to understand to use this library:
-//
-// Codepoint
-// Characters are defined by unicode codepoints, e.g. 65 is
-// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
-// the hiragana for "ma".
-//
-// Glyph
-// A visual character shape (every codepoint is rendered as
-// some glyph)
-//
-// Glyph index
-// A font-specific integer ID representing a glyph
-//
-// Baseline
-// Glyph shapes are defined relative to a baseline, which is the
-// bottom of uppercase characters. Characters extend both above
-// and below the baseline.
-//
-// Current Point
-// As you draw text to the screen, you keep track of a "current point"
-// which is the origin of each character. The current point's vertical
-// position is the baseline. Even "baked fonts" use this model.
-//
-// Vertical Font Metrics
-// The vertical qualities of the font, used to vertically position
-// and space the characters. See docs for stbtt_GetFontVMetrics.
-//
-// Font Size in Pixels or Points
-// The preferred interface for specifying font sizes in stb_truetype
-// is to specify how tall the font's vertical extent should be in pixels.
-// If that sounds good enough, skip the next paragraph.
-//
-// Most font APIs instead use "points", which are a common typographic
-// measurement for describing font size, defined as 72 points per inch.
-// stb_truetype provides a point API for compatibility. However, true
-// "per inch" conventions don't make much sense on computer displays
-// since different monitors have different number of pixels per
-// inch. For example, Windows traditionally uses a convention that
-// there are 96 pixels per inch, thus making 'inch' measurements have
-// nothing to do with inches, and thus effectively defining a point to
-// be 1.333 pixels. Additionally, the TrueType font data provides
-// an explicit scale factor to scale a given font's glyphs to points,
-// but the author has observed that this scale factor is often wrong
-// for non-commercial fonts, thus making fonts scaled in points
-// according to the TrueType spec incoherently sized in practice.
-//
-// DETAILED USAGE:
-//
-// Scale:
-// Select how high you want the font to be, in points or pixels.
-// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
-// a scale factor SF that will be used by all other functions.
-//
-// Baseline:
-// You need to select a y-coordinate that is the baseline of where
-// your text will appear. Call GetFontBoundingBox to get the baseline-relative
-// bounding box for all characters. SF*-y0 will be the distance in pixels
-// that the worst-case character could extend above the baseline, so if
-// you want the top edge of characters to appear at the top of the
-// screen where y=0, then you would set the baseline to SF*-y0.
-//
-// Current point:
-// Set the current point where the first character will appear. The
-// first character could extend left of the current point; this is font
-// dependent. You can either choose a current point that is the leftmost
-// point and hope, or add some padding, or check the bounding box or
-// left-side-bearing of the first character to be displayed and set
-// the current point based on that.
-//
-// Displaying a character:
-// Compute the bounding box of the character. It will contain signed values
-// relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
-// then the character should be displayed in the rectangle from
-// <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
-//
-// Advancing for the next character:
-// Call GlyphHMetrics, and compute 'current_point += SF * advance'.
-//
-//
-// ADVANCED USAGE
-//
-// Quality:
-//
-// - Use the functions with Subpixel at the end to allow your characters
-// to have subpixel positioning. Since the font is anti-aliased, not
-// hinted, this is very import for quality. (This is not possible with
-// baked fonts.)
-//
-// - Kerning is now supported, and if you're supporting subpixel rendering
-// then kerning is worth using to give your text a polished look.
-//
-// Performance:
-//
-// - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
-// if you don't do this, stb_truetype is forced to do the conversion on
-// every call.
-//
-// - There are a lot of memory allocations. We should modify it to take
-// a temp buffer and allocate from the temp buffer (without freeing),
-// should help performance a lot.
-//
-// NOTES
-//
-// The system uses the raw data found in the .ttf file without changing it
-// and without building auxiliary data structures. This is a bit inefficient
-// on little-endian systems (the data is big-endian), but assuming you're
-// caching the bitmaps or glyph shapes this shouldn't be a big deal.
-//
-// It appears to be very hard to programmatically determine what font a
-// given file is in a general way. I provide an API for this, but I don't
-// recommend it.
-//
-//
-// PERFORMANCE MEASUREMENTS FOR 1.06:
-//
-// 32-bit 64-bit
-// Previous release: 8.83 s 7.68 s
-// Pool allocations: 7.72 s 6.34 s
-// Inline sort : 6.54 s 5.65 s
-// New rasterizer : 5.63 s 5.00 s

-// which allows effects like bit outlines
-// onedge_value -- value 0-255 to test the SDF against to reconstruct the character (i.e. the isocontour of the character)
-// pixel_dist_scale -- what value the SDF should increase by when moving one SDF "pixel" away from the edge (on the 0..255 scale)
-// if positive, > onedge_value is inside; if negative, < onedge_value is inside
-// width,height -- output height & width of the SDF bitmap (including padding)
-// xoff,yoff -- output origin of the character
-// return value -- a 2D array of bytes 0..255, width*height in size
-//
-// pixel_dist_scale & onedge_value are a scale & bias that allows you to make
-// optimal use of the limited 0..255 for your application, trading off precision
-// and special effects. SDF values outside the range 0..255 are clamped to 0..255.
-//
-// Example:
-// scale = stbtt_ScaleForPixelHeight(22)
-// padding = 5
-// onedge_value = 180
-// pixel_dist_scale = 180/5.0 = 36.0
-//
-// This will create an SDF bitmap in which the character is about 22 pixels
-// high but the whole bitmap is about 22+5+5=32 pixels high. To produce a filled
-// shape, sample the SDF at each pixel and fill the pixel if the SDF value
-// is greater than or equal to 180/255. (You'll actually want to antialias,
-// which is beyond the scope of this example.) Additionally, you can compute
-// offset outlines (e.g. to stroke the character border inside & outside,
-// or only outside). For example, to fill outside the character up to 3 SDF
-// pixels, you would compare against (180-36.0*3)/255 = 72/255. The above
-// choice of variables maps a range from 5 pixels outside the shape to
-// 2 pixels inside the shape to 0..255; this is intended primarily for apply
-// outside effects only (the interior range is needed to allow proper
-// antialiasing of the font at *smaller* sizes)
-//
-// The function computes the SDF analytically at each SDF pixel, not by e.g.
-// building a higher-res bitmap and approximating it. In theory the quality
-// should be as high as possible for an SDF of this size & representation, but
-// unclear if this is true in practice (perhaps building a higher-res bitmap
-// and computing from that can allow drop-out prevention).
-//
-// The algorithm has not been optimized at all, so expect it to be slow
-// if computing lots of characters or very large sizes.

-// Finding the right font...
-//
-// You should really just solve this offline, keep your own tables
-// of what font is what, and don't try to get it out of the .ttf file.
-// That's because getting it out of the .ttf file is really hard, because
-// the names in the file can appear in many possible encodings, in many
-// possible languages, and e.g. if you need a case-insensitive comparison,
-// the details of that depend on the encoding & language in a complex way
-// (actually underspecified in truetype, but also gigantic).
-//
-// But you can use the provided functions in two possible ways:
-// stbtt_FindMatchingFont() will use *case-sensitive* comparisons on
-// unicode-encoded names to try to find the font you want;
-// you can run this before calling stbtt_InitFont()
-//
-// stbtt_GetFontNameString() lets you get any of the various strings
-// from the file yourself and do your own comparisons on them.
-// You have to have called stbtt_InitFont() first.
-
-
-STBTT_DEF int stbtt_FindMatchingFont(const unsigned char *fontdata, const char *name, int flags);
-// returns the offset (not index) of the font that matches, or -1 if none
-// if you use STBTT_MACSTYLE_DONTCARE, use a font name like "Arial Bold".
-// if you use any other flag, use a font name like "Arial"; this checks
-// the 'macStyle' header field; i don't know if fonts set this consistently

-/////////// THREAD SAFETY
-
-// Individual stb_vorbis* handles are not thread-safe; you cannot decode from
-// them from multiple threads at the same time. However, you can have multiple
-// stb_vorbis* handles and decode from them independently in multiple thrads.
-
-
-/////////// MEMORY ALLOCATION
-
-// normally stb_vorbis uses malloc() to allocate memory at startup,
-// and alloca() to allocate temporary memory during a frame on the
-// stack. (Memory consumption will depend on the amount of setup
-// data in the file and how you set the compile flags for speed
-// vs. size. In my test files the maximal-size usage is ~150KB.)
-//
-// You can modify the wrapper functions in the source (stbv_setup_malloc,
-// stbv_setup_temp_malloc, temp_malloc) to change this behavior, or you
-// can use a simpler allocation model: you pass in a buffer from
-// which stb_vorbis will allocate _all_ its memory (including the
-// temp memory). "open" may fail with a VORBIS_outofmem if you
-// do not pass in enough data; there is no way to determine how
-// much you do need except to succeed (at which point you can
-// query get_info to find the exact amount required. yes I know
-// this is lame).
-//
-// If you pass in a non-NULL buffer of the type below, allocation
-// will occur from it as described above. Otherwise just pass NULL
-// to use malloc()/alloca()

-/////////// PUSHDATA API
-
-#ifndef STB_VORBIS_NO_PUSHDATA_API
-
-// this API allows you to get blocks of data from any source and hand
-// them to stb_vorbis. you have to buffer them; stb_vorbis will tell
-// you how much it used, and you have to give it the rest next time;
-// and stb_vorbis may not have enough data to work with and you will
-// need to give it the same data again PLUS more. Note that the Vorbis
-// specification does not bound the size of an individual frame.
-
-STBVDEF stb_vorbis *stb_vorbis_open_pushdata(
- const unsigned char * datablock, int datablock_length_in_bytes,

-// the first N bytes of the file--you're told if it's not enough, see below)
-// on success, returns an stb_vorbis *, does not set error, returns the amount of
-// data parsed/consumed on this call in *datablock_memory_consumed_in_bytes;
-// on failure, returns NULL on error and sets *error, does not change *datablock_memory_consumed
-// if returns NULL and *error is VORBIS_need_more_data, then the input block was
-// incomplete and you need to pass in a larger block from the start of the file
-
-STBVDEF int stb_vorbis_decode_frame_pushdata(
- stb_vorbis *f,
- const unsigned char *datablock, int datablock_length_in_bytes,
- int *channels, // place to write number of float * buffers
- float ***output, // place to write float ** array of float * buffers
- int *samples // place to write number of output samples
- );
-// decode a frame of audio sample data if possible from the passed-in data block
-//
-// return value: number of bytes we used from datablock
-//
-// possible cases:
-// 0 bytes used, 0 samples output (need more data)
-// N bytes used, 0 samples output (resynching the stream, keep going)
-// N bytes used, M samples output (one frame of data)
-// note that after opening a file, you will ALWAYS get one N-bytes,0-sample
-// frame, because Vorbis always "discards" the first frame.
-//
-// Note that on resynch, stb_vorbis will rarely consume all of the buffer,
-// instead only datablock_length_in_bytes-3 or less. This is because it wants
-// to avoid missing parts of a page header if they cross a datablock boundary,
-// without writing state-machiney code to record a partial detection.
-//
-// The number of channels returned are stored in *channels (which can be
-// NULL--it is always the same as the number of channels reported by
-// get_info). *output will contain an array of float* buffers, one per
-// channel. In other words, (*output)[0][0] contains the first sample from
-// the first channel, and (*output)[1][0] contains the first sample from
-// the second channel.
-
-STBVDEF void stb_vorbis_flush_pushdata(stb_vorbis *f);
-// inform stb_vorbis that your next datablock will not be contiguous with
-// previous ones (e.g. you've seeked in the data); future attempts to decode
-// frames will cause stb_vorbis to resynchronize (as noted above), and
-// once it sees a valid Ogg page (typically 4-8KB, as large as 64KB), it
-// will begin decoding the _next_ frame.
-//
-// if you want to seek using pushdata, you need to seek in your file, then
-// call stb_vorbis_flush_pushdata(), then start calling decoding, then once
-// decoding is returning you data, call stb_vorbis_get_sample_offset, and
-// if you don't like the result, seek your file again and repeat.

-// of callback to your code. (But if you don't support seeking, you may
