Thank you Joel.
How do you feel about the common practice of damping front and rear walls only? I've worked in a few studios set up this way, but the walls were 100% covered in acoustic foam, front and rear, but with nothing on the sides. The rooms were not asymetrical. I've also seen some instalations where damping is installed in small 1x1' panels spaced about the wall, with occasional basstraps.
I do not have any working experience with this, but im looking to get a pretty neutral sounding room, i dont have to worry about glass, but materials are an issue, normal gypsum walls and a concrete floor with carpet over. If anyone has advice for me, or people looking to build a studio in general please post it.
Thanks!

If you're really short on money for acousting, the most important thing would be to have acoustic foam / plates placed between the mixing point and the monitoring to avoid the worst reflections coming from the walls, and the same goes with the roof of course. It's good to have the back end of your room acousted too, but it doesn't count that much as the walls.
If you have some money to spend on it, you can always build a floating floor and possibly a floating roof too, and there are probably lots of instructions in the web for building floating floors. We'd need to build a floating floor for ourselves since our floor is relatively thin and it rumbles a bit while playing out loud. However we haven't had time, money and interest for it yet. The same goes for basstraps.. there's a picture I draw of a nice building instruction for a powerful bass-trap (designed by Ethan Winer) available on my site too, at Docs & Files -> Acousting. Such traps are cheap to build and small to place in your studio, and I've heard they're powerful on killing those standing waves. I wish I only had more money for progressing with the workshop

Well, after reading through everything you did to create that studio its hard to believe you need to do any more work. On the site you said that the sawdust in the corners was working as a basstrap. Are you saying that its just not working as well as a specific basstrap, or that its not working on the same frequencies as a specific basstrap?
Unfortunately, money is an issue for me right now, so i can't go crazy on acousting materials. But i'm going to make sure to get the front wall damped for now, work on the rest later.

The sawdust in corners isn't working as a basstrap but it breaks down a bit of those low end reflections (each corner in a room boosts low end by 3dB, so an imaginary room would be some sort of a modified oval-ball... maybe an asymmetrical raindrop shape would be great? ). The whole acousting thing didn't cost that much; We got all the woodstuff, wool and acousting panels for around 350E in overall, and the sawdust was free of charge. I really would like to build a 2nd floor on top of the current one and put some wool in between. It would also be great to wire things up so that the wiring was done inside the floor instead of having wires circling all around. It would also let us use shorter wires too, leading to gain of quality in the recordings a bit that way as well (would probably gain the quality a lot more if we bought some high-end cables to replace the current ones though)

Alright, i guess i misunderstood what you were writing in the website, i thought you were saying that sawdust worked as a basstrap, but it really just works to damp out low end in the corners, gotcha.
So as a revised design i was thinking about building out an almost octagonal room, except the walls would not be of equal length. Think square with corners cut off, but not a the same angles front and rear. That would alleviate the boost that you would see in corners, and if i get the angles right, reflections will not bounce back to the source... What do you think?
