maintainer-needed@gentoo.org A set of Python modules and utility programmes to deal with Replay Gain information -- calculate it (with GStreamer), read and write it (with Mutagen). It has support for Ogg Vorbis (or probably anything stored in an Ogg container), Flac, WavPack (oddly enough) and MP3 (in different incarnations). There‘s also a command-line programme, replaygain, that works very similar to its like- named cousins, most prominently vorbisgain and mp3gain -- only that it works for all those supported formats alike. collectiongain on the other hand is a kind of fire-and-forget tool for big amounts of music files. rgain fk/rgain
