| − | '''.OGG''', or Ogg (see [http://en.wikipedia.org/wiki/Ogg Ogg file format]), is a file format for compressed multimedia files and a popular competitor to [[.MP3]]. Unlike MP3, Ogg uses an open-source, open-standard format and a permissive license, both of which allow it to be incorporated into the FS2_Open source code. Also unlike MP3, Ogg is a [http://en.wikipedia.org/wiki/Container_format container format], meaning that it can contain video data (via the Theora codec) in addition to audio data (via the Vorbis codec).

| − | Since Ogg delivers significantly smaller file sizes than [[.WAV]], while retaining substantially the same level of audio quality, it is becoming more and more frequently used in FSO-targeted mods. Ogg is not, however, a lossless format -- i.e., it is not possible to exactly reconstruct the original data from an .OGG file because some is "lost" in the conversion process. This is not usually a problem, however, because a high-quality .OGG file is usually indistinguishable from the source. A popular lossless alternative to Ogg Vorbis is [[.FLAC]].
