Attic home studio acoustics advice(low budget)

First off I want to say that all of this is not going to happen anytime soon, I just would like to know where to start first if I wanted to treat my room, here goes(I don't have any money right now and I'm just 15 years old). I've already read alot about treating a room, but I think my room is quite different from most of the examples, the room has sloped walls, hollow space behind walls etc. I've also read alot about acoustics theory(standing waves etc), but I don't really understand it yet so I've got no idea where to start with my plans. I have a very bad shaped room, it lookes like this from the outside: (I'm no hero with sketchup, sorry) Inside: http://s161.photobucket.com/albums/t227/XGBeatz/th_kamer_binnenkant.jpg Outside: http://s161.photobucket.com/albums/t227/XGBeatz/th_kamer_buitenkant.jpg Against the concrete wall(where the bed is), there is also a drumkit, but that really slowed down the program so i left it out, and ofcoarse the desk etc is not the exact model i have, but its close. My "monitors" are placed on the top shelf of the desk, on the desk is my pc with my DAW. There is also a window on the right wall(was causing problems to make somehow, sketchup can be hard sometimes). The wall with the door is hollow, the frame is made of 1.57"x2.36" wooden beams, the cardboard is 0.27" thick and the space in between is around 2.75". The sloped walls are made of wood, behind them is roof insulation. The floor is concrete with thin carpet on it. On the outside drawing you can see that there is hollow space behind the non sloped wall, that wall is very thin cardboard. the units are in cm; 357cm = 11.7ft 325cm = 10.6ft 466cm = 15.3ft 93cm = 3ft 365cm = 12ft If my tangent calculations are correct, then the roof is sloped at around 30 degrees. I cannot specify any budget right now as I don't know how much I will earn when I get a summer job, but I'm guessing over time it could be $600 or so, but it could be more, I have no idea right now. I hope this is enough information to advice me.

154 views and not a single reply? Do I need to include more details?

Probably for two reasons - one, it's trickier than people who are also just learning will venture a guess at - and two, the pix show up so wide it's a pain to scroll sideways to read every line of text. Please read this http://www.johnlsayers.com/phpBB2/viewtopic.php?t=3231 (it's the very top post in the forum) and try to follow the parts about posting pix. (including the request to post the actual pix HERE so future readers can still find them) If you need help converting/resizing, post back and we'll help you figure that part out. One thing that'll help without losing detail is to trim off all the blank space around the sketches. Once the thread isn't such a pain to follow, we can get into the details... Steve

The other factor in not getting any replies is that this thread was started in the Studio Construction forum, although the questions are primarily acoustics related. As such, I'll move this to the Acoustics forum, where those who frequent the area are, I think, more likely to be able to contribute some constructive advice. --Keith :mrgreen:

For any small room, there are two main goals: first, get the low end under control. This is done most easily by putting lots of thick absorption in the corners. In your case, the sharp corner above your head is prime, you could build a massive superchunk there, as well as in the other room corners. Second, create a RFZ at your mix position. This involves absorbing early reflections (have a friend move a mirror along all the walls while you sit at your mix position.... anywhere you see your speakers in the mirrors, put absorption there). Those are 2 very good rules of thumb to get you started.

Thanks for the advice. Sorry for the big pics, I put thumbnails instead now. And one thing I forgot to mention; This is a rental house, so anything I change about the room musn't cause any real damage to the walls(big holes, glueing stuff etc). The only wall where anything can be done with is the wall with the door, as is it self-built. What is the best location to place my monitoring setup? I read that against parallel walls is a no-no. And adding the images as attachments also makes you scroll, is there any other way?
