You can get packages ofSo how is it that the Debian-packaged normalize works on MP3s? It mustencode as well as decode them since it modifies the MP3 file. (Curiously, it doesn't support Ogg-Vorbis!)
Ogg Vorbis has vorbisgain which does the same thing as normalize and I know that vorbisgain doesn't do any reencoding, it just adds meta-data to the file that players use to adjust the volume. Indeed I would go so far as to say that reencoding would be a very retarded way of going about it since both mp3 and ogg are lossy formats, but anything is possible[I don't know how normalize works].
