Maybe this topic has been beaten like the proverbial dead horse, but I'm a new kid on this particular block...so, I could really use some help. I intend to build a small studio in my house, the basement specifically. I have a maximum space of 10' X 15'. My question is this: what is the best shape for a home studio to be? Square? Rectangular? Not plumb? I don't want to build something that will create some weird harmonic resonance because of it's dimensions. I am somewhat familiar with the acoustic treatment I will need to isolate outside noises, but I could use some tips on that as well. Any and all responses welcome...and thanks in advance for the help. Oh, and don't worry, I tend to be flame retardent!
