-/*
- IMPORTANT:
-
- WASAPI is implemented for Callback and Blocking interfaces. It supports Shared and Exclusive
- share modes.
-
- Exclusive Mode:
-
- Exclusive mode allows to deliver audio data directly to hardware bypassing
- software mixing.
- Exclusive mode is specified by 'paWinWasapiExclusive' flag.
-
- Callback Interface:
-
- Provides best audio quality with low latency. Callback interface is implemented in
- two versions:
-
- 1) Event-Driven:
- This is the most powerful WASAPI implementation which provides glitch-free
- audio at around 3ms latency in Exclusive mode. Lowest possible latency for this mode is
- 3 ms for HD Audio class audio chips. For the Shared mode latency can not be
- lower than 20 ms.
-
- 2) Poll-Driven:
- Polling is another 2-nd method to operate with WASAPI. It is less efficient than Event-Driven
- and provides latency at around 10-13ms. Polling must be used to overcome a system bug
- under Windows Vista x64 when application is WOW64(32-bit) and Event-Driven method simply
- times out (event handle is never signalled on buffer completion). Please note, such WOW64 bug
- does not exist in Vista x86 or Windows 7.
- Polling can be setup by speciying 'paWinWasapiPolling' flag. Our WASAPI implementation detects
- WOW64 bug and sets 'paWinWasapiPolling' automatically.
-
- Thread priority:
-
- Normally thread priority is set automatically and does not require modification. Although
- if user wants some tweaking thread priority can be modified by setting 'paWinWasapiThreadPriority'
- flag and specifying 'PaWasapiStreamInfo::threadPriority' with value from PaWasapiThreadPriority
- enum.
-
- Blocking Interface:
-
- Blocking interface is implemented but due to above described Poll-Driven method can not
- deliver lowest possible latency. Specifying too low latency in Shared mode will result in
- distorted audio although Exclusive mode adds stability.
-
- Pa_IsFormatSupported:
-
- To check format with correct Share Mode (Exclusive/Shared) you must supply
- PaWasapiStreamInfo with flags paWinWasapiExclusive set through member of
- PaStreamParameters::hostApiSpecificStreamInfo structure.
-
- Pa_OpenStream:
-
- To set desired Share Mode (Exclusive/Shared) you must supply
- PaWasapiStreamInfo with flags paWinWasapiExclusive set through member of
- PaStreamParameters::hostApiSpecificStreamInfo structure.

- Functions of type PaStreamCallback are implemented by PortAudio clients.
- They consume, process or generate audio in response to requests from an
- active PortAudio stream.
-
- When a stream is running, PortAudio calls the stream callback periodically.
- The callback function is responsible for processing buffers of audio samples
- passed via the input and output parameters.
-
- The PortAudio stream callback runs at very high or real-time priority.
- It is required to consistently meet its time deadlines. Do not allocate
- memory, access the file system, call library functions or call other functions
- from the stream callback that may block or take an unpredictable amount of
- time to complete.
-
- In order for a stream to maintain glitch-free operation the callback
- must consume and return audio data faster than it is recorded and/or
- played. PortAudio anticipates that each callback invocation may execute for
- a duration approaching the duration of frameCount audio frames at the stream
- sample rate. It is reasonable to expect to be able to utilise 70% or more of
- the available CPU time in the PortAudio callback. However, due to buffer size
- adaption and other factors, not all host APIs are able to guarantee audio
- stability under heavy CPU load with arbitrary fixed callback buffer sizes.
- When high callback CPU utilisation is required the most robust behavior
- can be achieved by using paFramesPerBufferUnspecified as the
- Pa_OpenStream() framesPerBuffer parameter.
-
- @param input and @param output are either arrays of interleaved samples or;
- if non-interleaved samples were requested using the paNonInterleaved sample
- format flag, an array of buffer pointers, one non-interleaved buffer for
- each channel.
-
- The format, packing and number of channels used by the buffers are
- determined by parameters to Pa_OpenStream().
-
- @param frameCount The number of sample frames to be processed by
- the stream callback.
-
- @param timeInfo Timestamps indicating the ADC capture time of the first sample
- in the input buffer, the DAC output time of the first sample in the output buffer
- and the time the callback was invoked.
- See PaStreamCallbackTimeInfo and Pa_GetStreamTime()
-
- @param statusFlags Flags indicating whether input and/or output buffers
- have been inserted or will be dropped to overcome underflow or overflow
- conditions.
-
- @param userData The value of a user supplied pointer passed to
- Pa_OpenStream() intended for storing synthesis data etc.
-
- @return
- The stream callback should return one of the values in the
- ::PaStreamCallbackResult enumeration. To ensure that the callback continues
- to be called, it should return paContinue (0). Either paComplete or paAbort
- can be returned to finish stream processing, after either of these values is
- returned the callback will not be called again. If paAbort is returned the
- stream will finish as soon as possible. If paComplete is returned, the stream
- will continue until all buffers generated by the callback have been played.
- This may be useful in applications such as soundfile players where a specific
- duration of output is required. However, it is not necessary to utilize this
- mechanism as Pa_StopStream(), Pa_AbortStream() or Pa_CloseStream() can also
- be used to stop the stream. The callback must always fill the entire output
- buffer irrespective of its return value.
