Unusual shaped basement bedroom. Ideas?

Hi everyone, thanks for a great forum. I have one room to work on music in my home and would appreciate any ideas to make it sound the best I can. It's small and unusually shaped basement bedroom with lots of corners, and a wall of closet doors. Not an ideal situation. The floor is carpeted. The walls are drywall and the ceiling is also drywall but with that "popcorn?" texture stuff on it. There are 2 drywalled soffits in the ceiling, hiding utilities. There are 2 windows, one of which is flush with a corner. This is a professionally finished basement. No demoing of walls or anything like that. I will primarily use this space to record vocals and guitars. Some mixing and personal mastering. Noise and neighbors are not an issue. I just need a balanced inspiring listening space. This place sounds funky. Not Good funky. I'm good with tools however not so much with money :D . Would like to keep this under $500. This is the first time I've used the sketchup program. Pretty neat. Ceiling is 7ft 4 1/2 inches at highest. Width is 10ft 6 inches Length is 13ft on half the room Length is 11ft 9 inches on other half I guess I'm looking for opinions on where to start for treatment, besides moving. Thanks

for your budget - plan on getting a bunch of 1x lumber, rigid insulation, and cloth to build absorbers. using a bunch of 1x1 and rigid insulation and cloth you will build 12 4" thick absorbers for the front wall, side walls, closet doors, and several on the ceiling. you will place several absorbers on your back wall. here's a dynamic SU component absorber which you can dissect to build yours. you could use some rolls (smallest in diameter to fit your space) of pink insulation and stack them in all of the corners, cover the corner with cloth and 1x1 trim to conceal. the compression of the rolls and the plastic on the rolls increases the density of the insulation and reflects some highs. you might consider removing the carpet and polishing the concrete (?) or placing some heavy finished plywood over a portion where you record acoustical instruments. get your monitors up and off your desk to ear height or slightly above - maybe behind the desk on stands - maybe replace your desk (assuming it's like the one in the drawing) with something smaller and/or less reflective.

Thank You for all your help! I added a bunch of panels to this sketchup. Unfortunately I couldn't figure out how to draw the treatment for the corners. I guess imagination will have to suffice for that part. My desk is a lot like the one in the picture, it was an L-shaped that I took apart. I've adjusted the desk's scale to make it more accurate. I primarily use the one for my computer and music as the other houses my homes ATT network router and printer among other assorted crap that I have no where else to go with. I added speaker stands that I forgot I already had and pulled the desk out from the wall a bit. 1. Too many panels? Too Few? Just right? Or totally wrong? 2. Yes, the floor is concrete under the carpet. Finished Plywood sounds great. Could laminate(w/built in pad) flooring snapped together sitting on top of the carpet be a good alternative? I only ask as I have a few boxes of that stuff laying around. Or would it be too thin or something? 3. I came under the realization that the rear corner (studio8.jpg) has a door there. Am I just screwed in that area? 4. I angled a panel to the ceiling in front of the window. Not sure why, just been looking at lots of examples and it seams people do this. Is this an effective thing to do? Thanks again

i think that's a good start and you can always add/remove if necessary.
