Odd question for you cats who've built home studios... My home office is also my music studio. Essentially about 12 x 12 but with some odd angle walls / ceilings / staircase that break up the standard cube. I'm adding a new dimension by building a green screen along two walls. Should be enough space for 3 musicians and related video production. The room has a slight amount of echo. Not much, but it's there if you listen closely. Wood laminate floor, some bookshelves to break up the wall space. I was thinking of adding minor acoustic treatment but with the big green screen suspended in front of a staircase that was contributing to the slight echo, I'm wondering if that might be unnecessary. The perpendicular side of the green screen is a foot out from the wall so there's airspace behind the partition. The green screen is a thin muslin material. Can any of you comment on how a big green screen might cut noise in a very small recording environment? This is a concept of how it will look. My ceiling is 8 feet so the screen will go from ceiling to floor.
