Butch, I agree with dnsacks. that looks alike a "normal" .wav file, just the top (typically Left ch) is hotter than the bottom (typically Right ch).
This type of file occurs to me when:
1] the placement of the mics is too far left or right and this is what they picked up
2] One of the mics gets turned outward on the mount or if head worn, you faced your head toward the stage while sitting off center.
3] the levels were set that way (accidentally)
4] the mic with lower levels may be damaged or not calibrated similar to the other mic (very low probability considering the screenshot; just trying to be thorough for you!)
Some DAW programs will allow you to raise the level of RT or Left independently; I don't use SF so can't comment on that.
Good luck- keep at it brother!
