What is a OGG? Ogg Vorbis is a fully open, non-proprietary,
patent-and-royalty-free, general-purpose compressed audio format
for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio
and music at fixed and variable bitrates from 16 to 128 kbps/channel.
Vorbis is the first of a planned family of Ogg multimedia coding
formats being developed as part of Xiph.org's Ogg multimedia project.
