Researchers Synthesize Real-Time Fracture Sounds

ChippedTeapot writes "Researchers at Cornell University have devised an algorithm for synthesizing sounds associated with brittle fracture simulations. Computers can now automatically generate synchronized sound, motion, and graphics for physically based fracture events, such as in future interactive virtual environments. The results will be presented at ACM SIGGRAPH 2010 in Los Angeles July 25-29. Check out the smashing results on YouTube."

As a post-audio SFX editor/designer, I would LOVE to have a virtual room full of junk to throw around, bang, break, bend, etc. Having convincing sounds is very nice, but even sounds that are not 100% accurate can still be used for very creative purposes. I love the work these guys are doing. This is another video of theirs I saved last year from an article submitted here but didn't make it to the main page:

Shouldn't this have been titled Breaking News?

for me, as a physicist, it's fascinating that they were able to do it. the human brain is a great tool to test how "natural" various simulations are, and when you succeed in fooling it, it means your model is very close to reality in a certain way.
in the study of complex phenomena, any ability to model is an important insight, because we don't have the math to understand what's happening just by using first principles.

as a sidenote, the problem of turbulence was well-known before the revolution of quantum and relativistic physics; still, Kolmogorov's scaling law (one of the most important results in turbulence) came in the 1940s. these problems are hard, and I will take my hat off to anyone who is able to cheaply reproduce aspects of nonlinear phenomena.
