your files are mp3, right? what you want to do is fairly simple, just use media-sound/mp3gain just direct your browser to http://mp3gain.sourceforge.net/ and get some background. i haven't found much documentation on-line, just install it and run mp3gain -h. i guess this is what you need, because: 1. the application does not perform normalization (which would mean decoding and re-encoding ), it only adjusts the replaygain tag in the mp3 file; 2. the adjustment is not based on peak amplitude, but on the ReplayGain "loudness" algorithm (don't know much of the details, but basically it's RMS calculation with some psychoacoustic adjustments, based on the "lodness curve"). check these options: -r - apply Track gain automatically (all files set to equal loudness) -k - automatically lower Track/Album gain to not clip audio -a - apply Album gain automatically (files are all from the same album: a single gain change is applied to all files, so their loudness relative to each other remains unchanged, but the average album loudness is normalized)
