Vorbis audio compression
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.
The bitstream format for Vorbis I was frozen Monday, May 8th 2000.
All bitstreams encoded since will remain compatible with all future
releases of Vorbis.
