Adds tags to Ogg Vorbis files to adjust the volume
VorbisGain is a utility that uses a psychoacoustic method to correct the volume of an Ogg Vorbis file to a predefined standardized loudness. It needs player support to work. Non-supporting players will play back the files without problems, but you'll miss out on the benefits. Nowadays most good players such as ogg123, xmms and mplayer are already compatible.
