High Quality Content by WIKIPEDIA articles! Xiph.Org Foundation is a non-profit organization that produces free multimedia formats and software tools. It focuses on the Ogg family of formats, the most successful of which has been Vorbis, an open and freely licensed audio format and codec designed to compete with the patented MP3 and AAC. Current development work is focusing on Theora, an open and patent-free video format and codec designed to compete with the patented MPEG-4, RealVideo, and Windows Media Video. In addition to its in-house development work, the Foundation has also brought several already-existing but complementary free software projects under its aegis, most of which have a separate, active group of developers. These include Speex, an audio codec designed for speech, and FLAC, a lossless audio codec.
