An all-pass filter changes the audio's frequency to phase relationship
without changing its frequency to amplitude relationship.
-The filter accepts parameters as a list of @var{key}=@var{value}
-pairs, separated by ":".
-
-A description of the accepted parameters follows.
+The filter accepts the following options:
@table @option
@item frequency, f
The filter can be either single-pole, or double-pole (the default).
The filter roll off at 6dB per pole per octave (20dB per pole per decade).
-The filter accepts parameters as a list of @var{key}=@var{value}
-pairs, separated by ":".

frequency @var{frequency}, and (3dB-point) band-width @var{width}.

In order to produce complex equalisation curves, this filter can
be given several times, each with a different central frequency.

+The filter accepts the following options:

The scale filter forces the output display aspect ratio to be the same
of the input, by changing the output sample aspect ratio.
-This filter accepts a list of named options in the form of
-@var{key}=@var{value} pairs separated by ":". If the key for the first
-two options is not specified, the assumed keys for the first two
-values are @code{w} and @code{h}. If the first option has no key and
-can be interpreted like a video size specification, it will be used
-to set the video size.
