Request for help - documenting Rockbox's audio codec support

Rockbox now supports almost 20 different audio formats (on the swcodec
targets) and I thought it would be useful to start documenting them in
more detail than the information available on the current SoundCodecs
My intention is to create a separate wiki page for each format supported
in Rockbox, and populate them with the following information:
1) A brief description of the format, with links for further
information, encoders, etc.
2) Details of the current status of playing that format in Rockbox -
any limitations, which tagging formats are supported, etc.
3) A table showing the decoding speed (the % realtime figure given by
test_codec) for a range of different encoding settings on the three
different architectures Rockbox runs on - Coldfire, PortalPlayer and the
Gigabeat's 300MHz ARM.
Related to 3) is the need to find a freely-distributed test track which
can be used to compare the decoding speed of the different codecs. If
anyone has suggestions for such a track, or views on any methodology we
should use to choose it, please say so.
I've added a first attempt at a page for the newly supported Monkey's
If anyone feels like working on pages for other formats, please feel
free to do so.
These pages are (automagically) linked to from the SoundCodecs page -
please make sure you add the "CategorySoundCodecs: Codec Name" line to
the bottom of any new page you add.
I think this page could also benefit from being restructured - e.g.
moving the main table into a "SoundCodecDevelopment" or similar page,
and leaving SoundCodecs to just document the currently supported formats.
