It's actually quite interesting- I can go into an apparently similar room and clap and the reverb has a very distinct color- go into the 'optimal' room and clap and the verb sort of vanishes into colorlessness. Instead of 'Klonng' it's like 'Khhhh' no mode reinforcements! |

Just remember that clapping will not excite the low freq modes determined by room dimensions - claps are high enough in freq to be controlled by surface treatments alone... |

Assume you can have a room of any shape or size, what would it be? |

Well, there's no perfect room, but if you pick up something like F. Alton Everest's 'Master Handbook of Acoustics' you can see charts of 'good sounding' ratios as well as ways to determine which dimensions yield the best low freq room response. |

I wrote a program to generate quadratic residue diffusor construction plans and I'm going to make some out of shipping plank styrofoam. |

Do you have a program to calculate the well depths of a 2 dimensional quadratic residue diffusor? |

GA told me to budget $150/foot to build plus his design and consultation (which is amazingly reasonable). Since I am building the facility on some wooded land, I can count on a bit less build-out costs as isolation won't be as hard to accomplish as it is in the city environment... |
