Ogg Vorbis is a high-quality lossy audio codec which is free of intellectual property restrictions (like those surrounding MP3). These are the tools that one needs to create and play Ogg Vorbis files on the commandline, as well as a simple commentor.

Vorbis is a ?lossy? codec, this means that lossy compression algorithms discard data in order to compress it better than would normally be possible. Examples include JPEG, Vorbis, and MP3 compression.
