Thanks again Steve.
Never opened a track from a major motion picture but thinking about it most of
the sound is at center from watching a few movies at home. Of course you have
now got me sitting paying more attention to the sound next time I watch a movie
instead of just taking it 'as is'. ;)
Most of what I'll do will be outdoor wildlife and the surround Ls & Rs will
come into their own I'm sure. I put a quick (60 second) test together yesterday
just to play with settings in the software. I was pleased with the result so my
next move is to focus something at center and play again.
Again, thanks for your advice and the Diegetic link.
