Digital synthesis of impact sounds
Vasileios Chatziioannou · 2015
Nonlinear interactions may impose several restrictions to numerical simulation attempts, in particular concerning the design of unconditionally stable algorithms. Such algorithms are required for real-time synthesis applications where virtual instruments may be modified on-line. One characteristic case of nonlinear interactions is that of impact sounds. This paper gives a brief summary of recently developed numerical techniques that are suitable for the simulation of systems involving collisions. A simple numerical example, involving a lumped collision model, is used to demonstrate the methodology, and further perspectives concerning the applicability of the presented family of schemes to real-time synthesis applications are discussed.
