Hi All,
I did end up building a partial ceiling poly over 1/3 of ceiling beam in my live room and it solved the flutter echo problem in the center of room. Thank you Glenn for the advice and plans.
I want to gain back some ambiance in my live/tracking room and think the best way is to cover some or all of the large bass trap and moving gobo panels with diffusion plates of some kind like the examples attached. I also could do away with the ceiling cloud and install mostly diffusion on the ceiling. I would greatly appreciate any and all opinions on this.
Thank you for your time and expertise,
Jason
