 @chapter Description
 @c man begin DESCRIPTION
 
 The libswresample library performs highly optimized audio resampling,
 rematrixing and sample format conversion operations.
 
 Specifically, this library performs the following conversions:
 
 @itemize
 @item
 @emph{Resampling}: is the process of changing the audio rate, for
f18ccb52
 example from a high sample rate of 44100Hz to 8000Hz. Audio
e903cb41
 conversion from high to low sample rate is a lossy process. Several
 resampling options and algorithms are available.
 
 @item
 @emph{Format conversion}: is the process of converting the type of
 samples, for example from 16-bit signed samples to unsigned 8-bit or
 float samples. It also handles packing conversion, when passing from
 packed layout (all samples belonging to distinct channels interleaved
 in the same buffer), to planar layout (all samples belonging to the
 same channel stored in a dedicated buffer or "plane").
 
 @item
 @emph{Rematrixing}: is the process of changing the channel layout, for
 example from stereo to mono. When the input channels cannot be mapped
 to the output streams, the process is lossy, since it involves
 different gain factors and mixing.
 @end itemize
 
 Various other audio conversions (e.g. stretching and padding) are
 enabled through dedicated options.
