First of all my I have to say Im new to this and my sole objective is to get the best possible quality sound w/ my limited resources. I have a home studio where i use a bedroom about 9' wide and 6' long very small, inside that room I built an even smaller booth with a window about 4' wide and 6' long, the room itself has a window and my apartment is located in a noisy NYC neighborhood the room seems to have a lot of echo and reverb but then again its kinda empty. Im using decent equipment mac pro w/ 2 tb hard drive, 8 gb ram, Neumann tlm 103 mic, avalon 737 sp, apogee ensemble, yamaha hs 80 montitors, and headroom headphone amp.. Given these factors is it a good idea to fully cover the booth w/ like say 4" foam, I also need ideas on how to treat the room I'm thinking of foam tiles behind the monitors and im building sound panels 4' high 2' wide and putting them on the adjacent wall are these good ideas??, if not care to share what has worked in small rooms?
