Description:
add Replay Gain volume tags to Ogg Vorbis files
vorbisgain calculates a percieved volume of an Ogg Vorbis file using the Replay Gain algorithm. It then stores a per-track and per-album volume adjustment in the file's tags, to let songs play back with a uniform volume. The process is non-destructive and does not change the audio data at all. . Many audio players in Debian support reading these tags, including XMMS, Quod Libet, amaroK, Muine, and Rhythmbox.
