Guess not, I looked online for a little over an hour, and through all my books...nothing. Sorry, I was sure I had heard of this before, maybe just in one of the classes I was in.
It does appear to resemble an A/B spaced pair the most.
The mic placement you described for the horn recording, what is the name of that technique? I know it is A/B Spaced pair basically, but I remember reading something similar to that before in college, and they had a specific name. It is not really important, just curious. Thanks!
