Whoa, what a can of worms I've opened! Sorry! Anyway, nothing is in the red. It's just that noisy/busy passages are peaking over 0dbs. None of it is the end of the world, but I want it to be right. Bob Katz's Digital Domain site is great, but it's a little over my head. I'll keep experimenting, but I'd love to hear more opinions. But, yeah...what is a master fader for, then?
