This software is a compressed audio format that is fully open and non-proprietary, designed for general-purpose use.
In fact, Vorbis even outperforms MPEG-1/2 audio layer 3, MPEG-4 audio (TwinVQ), WMA and PAC. Not only that, but Vorbis is just the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's Ogg multimedia project.
At the core of Vorbis lies libVorbis, which acts as the Ogg stream / Vorbis engine. With its impressive performance and open nature, Ogg Vorbis is a fantastic choice for anyone looking to compress their audio files without any proprietary fees or restrictions.
