sorry to hijack the thread, but Michael, why is everybody repeating that parallel walls are a big no-no ???
If you design a studio, the maths for it are waaaay easier with rectangular walls and you maximize space usage too... If your dimensions are good so will the room be.

Well, it's just the concensus of many studio design professionals that parallel walls aren't ideal for a studio.
From what I understand, the biggest reason for this is:
Parallel walls create standing waves. That is, the sound waves bounce directly off of one wall, and then interefere with sound waves comming from the source as the reflected wave heads directly back to the source. When this happens, some frequencies are cancelled out and others are boosted. This doesn't give an accurate representation of the music or sound being recorded. Angled walls, because reflected sound doesn't bounce directly back, eliminates this phenomena.
As far as the math goes, I have to disagree. Its just as easy to measure and cut a 12 degree angle as it is to measure and cut a 90 degree angle. Likewise its as easy to measure and cut a dimension of 6'-5 11/16" as it is to measure and cut a dimension of 6'-6".
While it is true that some space is lost, in proper studio design, the loss usually comes from implementing air space between the walls, rather than from angled walls. A good design will make use of most areas, and minimize the lost or un-usable area.
The net loss of say 3% - 5% of total floor space is a small price to pay for proper room acoustics and added isolation.
No one says you HAVE to have angled walls, its just a prefered method for optimal room acoustics.
