Ogg is a digital media [[container format]] developed by [[Xiph]] that encapsulates the [[Ogg Vorbis|Vorbis]] codec, or a number of other audio and video [[codecs]]. The actual compression format is Vorbis (or [[Theora]], [[FLAC]], [[Speex]], [[PNG]], etc.), depending on what format is within the ogg container.

Ogg is a multimedia container format, and the native file and stream format developed by the Xiph.Org Foundation, for their multimedia codecs. It is an open format free for anyone to use. It is usually used to store Vorbis audio (or, less commonly, Theora video), and because of this, "Ogg" has been used incorrectly to refer to Vorbis.

For more details, see Xiph's explanation of the Ogg container.
