Vorbis: Open Source Audio Encoding and Streaming Library

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.

It has been designed to completely replace all proprietary, patented audio formats. It is a lossy codec. Lossy compression algorithms discard data in order to compress it better than would normally be possible. Examples include JPEG, Vorbis, and MP3 compression.
