Vorbis

Ogg Vorbis is a completely free and open audio compression (codec) project from the Xiph.org Foundation, and is part of their Ogg effort to create free and open multimedia and signal processing standards.

Like all developments of the Ogg project, Vorbis is believed by the developers to be completely free from the licensing or patent issues raised by other proprietary formats such as MP3. Outside parties have doubted the claim that Vorbis would be patent free; but have so far not produced any supporting evidence so this has been derided by some as so-called "FUD": disinformation spread by large companies with a vested interest.

Compared to other audio formats Ogg Vorbis is relatively new, having been refined by developers until a stable version 1.0 of the codec was released on July 19, 2002.
