what software can remove cracks/distortion in mp3s?

[LongCoolMother]

i saw somewhere that a piece of software that came with my audigy soundcard can do this, but i cant seem to find it. whats it called? can soundforge remove the crackles in some of my mp3s? if it can, whats the option? is it "noice reduction"? because nero has an option called that. thanks.
