awesome. I was going to do this w/using the freq analysis in Audition, just to get an idea of where my peaks are, but this seems WAY better suited.
I assume I can run omni -> 702 -> line out -> line in on lappy (will borrow one from work). The only Omni mic I can easily get my hands on is a Studio Projects C4.. should work ok.... I hope.
but since I'm currently figuring a design for my sub, I'll wait until its done to do this.. garage project gets finished first, then I have room for sub project...
thanks for the link!
