Excellent thread! Props to Andre for making me aware of it. Now I'm more excited than I was a few hours ago about treating my room.
I think I'm going to take a break from researching design, construction and asking questions and just relax. I've been going at this acquiring knowledge thing for about 10 days in a row, at a rate of maybe 10+ hours per day. Before that, it was still several hours per day, researching gear and such. Besides, I haven't gotten full permission by my lady to turn our bedroom into a recording/mixing palace anyway.
I absolutely cannot wait to get a new place, with a separate room reserved solely for music. Should be this summer, but I have an album to record now, that can no longer wait. Ah....the joys of independent music.
Congrats on your room John! I haven't even gotten into diffusion yet. My brain needs a breather, and the room needs absorption before I can even think about delving into that realm of things, haha!
