vorbisgain 0.36-1ubuntu1 (i386 binary) in ubuntu dapper

 It calculates a percieved sound level of an Ogg Vorbis file using the
 ReplayGain algorithm. VorbisGain then stores in the comments (tags)
 in the file a suggestion on how the volume should be changed during
 playback, to get a uniform sound level.

 Players supporting this include XMMS 1.2.8 and newer, and Rhythmbox 0.7.0
