+<p>The libswresample library performs highly optimized audio resampling,
+rematrixing and sample format conversion operations.
+</p>
+<p>Specifically, this library performs the following conversions:
+</p>
+<ul>
+<li> <em>Resampling</em>: is the process of changing the audio rate, for
+example from a high sample rate of 44100Hz to 8000Hz. Audio
+conversion from high to low sample rate is a lossy process. Several
+resampling options and algorithms are available.
+
+</li><li> <em>Format conversion</em>: 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 &quot;plane&quot;).
+
+</li><li> <em>Rematrixing</em>: 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.
+</li></ul>
+
+<p>Various other audio conversions (e.g. stretching and padding) are
+enabled through dedicated options.
