Ive been asking questions about acoustic treatment for my room, where I plan on recording myself playing acoustic guitar, singing and rapping on a neumann tlm 102. It was suggested that I should post my room dimensions, so here they are. Short wall-6.1ft Long wall-8.2ft Theres also a little nook that extends out to 10.5ft. And the ceiling is 7.5 ft high. Ive attached a few photos of the room. The black curtain on the wall is covering a window. I have a few foam panels up, but know those don't do much. I also have an area rug over most of the tile floor. Looking to buy some bass traps, dont want to build them. Any recommendations or advice on ways to get my room to sound better? There's not much echo, but when I clap my hands loudly, I hear a metallic high pitched ringing sound.
