Sarge's Smoke Break #41: Reducing Reverb In The Guinness Room

So NONE of this involved a fresh outlay of money. I bought two HUGE pieces of acoustic foam back in 2020 (something like 7'x8' each?) and I still have one of them intact, even after this project, in a closet. Hopefully this eliminates the ball-busting from Babel Audio.
In case anyone else doesn't know what in the fuck reverb is (I had to look that up myself), here it is. Easiest explanation is fragments of ricocheted sound. Not quite a full echo where you can make out entire words such as we learned about in 'Predator' - "My, you have a big pussy... my, you have a big pussy"!
