I've used the program
"normalize-audio" a number of times to good
effect.

I see that there is a replaygain script for Amarok, though I haven't
used it. If you can get it to work, replaygain is probably the best
solution, since it doesn't change the data (as normalize-audio does, I
believe) but rather sets an id3 (?) tag.
Be warned though that there is no perfect solution, since different
types of music are compressed differently. No matter what strategy one
adopts, a classical piece will have quiet parts and loud parts, and
whichever of these you try to match with the volume of a pop piece,
the other will sound wrong. Then of course there's the tricky issue of
whether to change the volume per-song or per-album...
HTH :)
