VorbisGain {corrects the volume of an Ogg Vorbis file to a predefined standardized loudness} by calculating the file's percieved sound level 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. You then need to use an audio player that knows about and acts on that suggestion.
