This paper describes a real-time technique for generating realistic and compelling sounds that correspond to the motions of rigid objects. By numerically precomputing the shape and frequencies of an object's deformation modes, audio can be synthesized interactively directly from the force data generated by a standard rigid-body simulation. Using sparse-matrix eigen-decomposition methods, the deformation modes can be computed efficiently even for large meshes. This approach allows us to
