Doesn't sound to me like the solution to your problem is at all
inherently linux related but there are sure lots of good tools available
for this OS.

If you are new to linux audio, I would suggest get Audacity from Planet
CCRMA, import the songs (ripped off your existing CD) into Audacity
(probably one at a time), use Audacity's "Normalize" or "Amplify" effect
and maybe play with one of the compressors in the plug-in lists (I've
used the "Dyson Compressor" to get a file that just almost touches 0 dB
in the loud parts and is nice and "fat" looking. You will have done a
very quick and dirty mastering job that should make it sound lots better
in your CD player.

Jan Depner just suggested "Gnome Wave Cleaner (GWC) works great." I
haven't tried it but want to. I have tried Audacity's "Noise Removal"
with not very good results.

Audacity has a "Declipper" in it's plug-ins list (same plug-ins
available to all other linux apps) that seems to help some. But if the
file is badly clipped, it's going to take some pretty smart software
(and user) to fix it if it's even possible. Lost information can never
really be retrieved, only guessed at.

You'll like Audacity and after having some success with it you will be
ready to try the much more complex but way-cool JACK-Ardour-Jamin, etc,
etc route.

Good luck and feel free to email me with any Audacity questions you
