More specifically, I need suggestions on controlling bleed between mics-- in this case, controlling the drums as much as possible. The acoustic situation is this-- a church of about 150 seat capacity with a vaulted ceiling, and a raised stage about 30' by 20' deep with a stone wall behing the instrumentalists. The only "acoustic treatment" applied is one of those plexi gobos in front of the drums. I plan to tweak mic placement to avoid phase issues and too much bleed, but does anyone have any suggestions of temporary acoustic isolation I could use to isolate the drums? Thanks.
