Basically, it's a two-step process : (1) analyze the 'effective loudness' of a track, and (2) add a tag indicating the difference between the measured 'effective loudness' with a reference level of 89 dB SPL http://wiki.hydrogenaudio.org/index.php?title=ReplayGain The above wiki article might be out of date with regards to the available software. Try asking around in the HydrogenAudio forums.

What you're looking for is called "replay gain" (alternati= ve spelling, "replaygain"). Basically, it's a two-step proces= s : (1) analyze the 'effective loudness' of a track, and (2) add a = tag indicating the difference between the measured 'effective loudness&= #39; with a reference level of 89 dB SPL
