So I was taping an opening band tonight at sloss furnaces here in Birmingham and the amount of chatty people behind the stand annoyed me, and was only accentuated by the rear lobe in the hypercardiod pattern I was running.
Here's my question: has anyone tried to take the rear lobe out of play using a some sort of baffle? Think mics set up with a J-disc or something behind them to absorb the sound coming from the rear of the mic. Seems like it would work, but I'm wondering if it would have any consequences to the overall sound of the recording. Would there be any noticeable difference (save the desired effect of no rear-of-mic chatter)?
I'm interested to hear if anyone has tried this in a club-type situation where you have to run hypers to clean up the shitty room but also want to cut out idiots making noise behind you. Opinions needed, fire away!
