I thought about your question some more, and I have another answer. If you consider the waves of sound coming from a point then yes, there is a kind of focal point any time you have walls coming together. Even when walls angles are not equal, there's a focal point (it just may be in a strange location). In the case of my tracking room, if you stand right where the end of the piano is on
the floorplan and beam your sound north the east corner, you will get roughly equal reflections coming back from four walls, providing an apparent amplification effect. But there are three things to remember about that:
- There are ten 12' RPG reversable BAD panels providing diffusion or absorption and another two 6' panels on the side walls
- You can choose to point your sound in the opposite direction
- You don't have to put your mic in that one location
On the plus side, if you consider the reflections you get from the opposite corner (where the sound has to travel down the length of the room to get there), then you get the multiple reflection diffusion effect I described in my previous post. And the advantage of the symmetry is that you can a much more even, predictable response from the room, meaning that you have an easier time moving microphones for the convenience of musicians without the room getting all funny on you.
