Hmm. Replied to Michael but it didn’t post. So, Shuffling. This actually started with Mr. Blumlein and his stereo mic technique. I read about it via something from Michael Gerzon, either from a couple of web boards, the Mastering web board, of which, Bob Katz was a part, or maybe even earlier in the old rec.pro.audio days. Anyways, Mr. Gerzon expounded on it and there are some plugins built with shuffling built in, one of which is from Waves. Mr. Gerzon also developed his own take on stereo miking, using almost half X-Y and half ORTF.
I tried to attach a link to a pdf written by Michael Gerzon. Maybe that link kicked my post out? Don’t know. Anyways, I’ll post the URL via this post. Just copy and paste. Will see if that let’s my post through.
