June 22, 2000 Ogg Vorbis is a fully Open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for high quality (44.1-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. This places Vorbis in the same class as audio representations including MPEG-1 audio layer 3, MPEG-4 audio (AAC and TwinVQ), and PAC. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiphophorus's Ogg multimedia project. Vorbis Home Table of ContentsNewsVorbis 1.0 beta launched at the MP3 summit on June 20, 2000. The iCast sponsored demo site at http://www.vorbis.com/ now offers binary downloads of encoders and plugins for Linux and Windows (and links to others like Be will be there soon if not already), audio tracks in .ogg format and other goodies. The beta launch is not entirely complete; we still have quite a few tracks (and a few complete albums) to get up on the site, as well as several encoder features that didn't quite make it in by the 20th.
