That didn't sound like any sort of noise reduction I'd ever heard, and that doesn't explain why it was on some of the commercials. I don't know what you guys think of the live engineers who handle these sorts of gigs, but they are not stone-deaf chumps, nor are the people in the audience. If that noise has been audible in the house, LOTS of people in that theater would have raised holy hell. Hell, I would've gotten fired from a bar gig for sound like that - no way was that in the house. -Dan.
