I failed to acknowledge the modified SASS. I know that others here use 
them too. You've reminded me to put the SASS on my list of things to 
experiment with when I get the chance.

Yup. That's why I referred to Klaus' wise reminder. I like your term 
"cognitive scene analysis apparatus." That's exactly what's lacking 
with mics. On the other hand, as you said later in your comments, the 
listener does apply some scene analysis even to recordings. The other 
day my children and their spouses were at the house and I played some 
field recordings for them. The daughter-in-law was under headphones 
when I played a recording I made on a United 727 flight to Chicago a 
few years ago. As the plane accelerated down the runway and lifted off, 
there she was, pressed back in the chair as if she were right there. 
Her scene analysis apparatus was working overtime to paint a very vivid 
image for her. It was fun to observe.

Nice word picture, Walt.

Sorry I was unclear on this. I, too, am quite a purist with respect to 
field recordings. I do a lot of cosmetic editing to clean things up and 
condense them, but almost no mixing. The mixed/panned multi-mono 
recordings I've done have been in my studio work -- original music for 
media, albums for recording artists and big live broadcasts. Even in 
those settings, I prefer to work with stereo pairs whenever possible.
