Dithering is used to reduce the harmonic distortion that can occur as part of
the conversion of audio data from e.g. 32-bit floating point to 16-bit integer
format (data coming from effect processing converted for playback or final long
term storage).

See http://en.wikipedia.org/wiki/Dithering for more information about (audio)
dithering.  At least one obvious implementation under LGPL is available, as
part of the WaveGain program (http://www.rarewares.org/others.html).

It's a useful feature to have at some point in the future.  The target is most
probably the audioconvert element, as this is where any reduction of the
bandwidth actually happens.
