I maintain a detailed reverberation (RT60) calculator at http://threedb.com/rt.php and a primitive, but realtime 2D room beamtracer at http://threedb.com/2d-viewer.php. You'll also find my large database of absorption coefficients there.

As an enthusiast, would you pay some modest amount for access to more related calculators and analysis tools?

Hello, thanks! As I've said, I have a technical background, such that I have the basic understanding of how the sound works, what decibels are and that basic stuff, but I've never had any acoustic classes. I'm just trying to figure out what's happening in my living room and how I can improve the sound. I know that the shape and the minimal furniture are far from any ideal, but I have the problems of even hearing the clear dialogues when watching the movies and I hope I can do something about that. The room acoustics at the moment is such that even talking to the other people there is for me harder than in some better setting.
