<<<Next question: I am looking for a good noise reducer that can decrackle, hum remove, etc. Sound Soap (not the pro version) is not expensive and looks pretty good. Do you recommend it?>>>
No, and not because it doesn't work. It works as well as the one inside SoundTrack Pro which you may already own.
<<<good noise reducer >>>
"I have no show because of noise and distortion, but I have to try and rescue it anyway."
Noise Reduction software, as good as it is, fails to rescue damaged shows well over half of the time. The problem is that by the time you realize you need it, it's too late. We did a SoundTrack Pro noise workup here for somebody. I'll look.
