Program to show wave's motion and modes?

I was wondering if there is a program that let's you test a room in a virtual environment? For example you have a room design. You enter the material type of the walls. You place a source of sound anywhere within the room. The program shows you the wave paths, the accumulations, the nulls, the standing waves, etc. That would be sooooo useful. Please say yes. :P

There's a bunch here: http://forum.studiotips.com/viewforum.php?f=27 You'll need to be logged in to access them. I've been using the Chris Whealy calcs. which are ffffiiine :D not quite wave paths and stuff, but general absorbtion and reflection stuff. Wave paths would be confusing I think seeing as a sound wave propogates in a complex 3D scatter from any point it hits. I've been using raytracing in Maya for checks of a single bounce, but its only really a rough guideline for direct lines, anything more than that I figure it's not much use. Raytracing works the wrong way round really.

Thanks, I'll check it out.

http://www.cara.de/ENU/cara-powerpack.html For $69 Euro, this is exactly what you asked for; best bargain in the known universe, with a warning; be prepared to spend a LOT of time with this, it's DEEP and has its own CAD interface to learn before you can "build" your environment. The video tutorials will give you a jump start, but plan on a few DAYS of messing with it. Still, a very useful program - I've still not found enough time to figure it all out, beyond knowing what's possible (but I'm always spread thinner than I should be) Check it out... Steve

thanks
