The audio layer is most commonly provided by the music-oriented Vorbis format but other options include the human speech compression codec Speex, the lossless audio compression codec FLAC, and OggPCM.
Before 2007, the .ogg filename extension was used for all files whose content used the Ogg container format. Since 2007, the Xiph.Org Foundation recommends that .ogg only be used for Ogg Vorbis audio files. The Xiph.Org Foundation decided to create a new set of file extensions and media types to describe different types of content such as .oga for audio only files, .ogv for video with or without sound (including Theora), and .ogx for multiplexed Ogg.[5]
As of August 4, 2011, the current version of the Xiph.Org Foundation's reference implementation, is libogg 1.3.0.[2] Another version, libogg2, has been in development, but is awaiting a rewrite as of 2008.[6] Both software libraries are free software, released under the new BSD license. Ogg reference implementation was separated from Vorbis on September 2, 2000.[7]
Because the format is free, and its reference implementation is not subject to restrictions associated with copyright, Ogg's various codecs have been incorporated into a number of different free and proprietary media players, both commercial and non-commercial, as well as portable media players and GPS receivers from different manufacturers.
