The Xiph.Org Foundation is a nonprofit organization that develops free, open-source multimedia formats and software, most notably the Ogg family of formats and the Vorbis audio codec designed to compete with proprietary codecs like MP3 and AAC. The foundation's work on codecs such as Opus and FLAC provides patent-free alternatives for audio compression, while its Daala project aims to create a royalty-free video codec to compete with HEVC and VP9. By focusing on open protocols and software, Xiph.Org differentiates itself from commercial codec vendors by ensuring unrestricted use for developers and businesses without licensing fees.
