The Ogg Vorbis CODEC project

http://www.xiph.org/ogg/vorbis/

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. This places Vorbis in the same
competitive class as audio representations such as MPEG-4 (AAC), and similar
to, but higher performance than MPEG-1/2 audio layer 3, MPEG-4 audio
(TwinVQ), WMA and PAC.

Vorbis is the first of a planned family of Ogg multimedia coding formats
being developed as part of Xiph.org's Ogg multimedia project.
