Algorithmically Generated Realistic Sound On Show At SIGGRAPH

Researchers at Cornell University are hard at work on a project that sounds odd at first, but is in fact a perfectly natural extension of existing 3D and computing technology. They're making an engine for producing the sounds of colliding objects by simulating the materials of the objects themselves in a virtual space, and then calculating the forces and vibrations that would be produced. Academically it's a challenging proposition, but it has plenty of practical applications as well. The simulation of noise propagation perhaps would be most easily applied in 3D games, which despite having nearly photorealistic models, textures, and lighting, still rely on a limited cache of pre-recorded sounds to play when, say, a table tips over. By simulating every object on the table and tracking the physical effects of collision with the floor, other objects, and the resulting reverberations, a more realistic and accurate sound can be created on the fly — or at least that's the theory.
