Synthetic percussion
Stefan Bilbao · The Journal of the Acoustical Society of America · 2006
The widespread availability of fast small computers has removed many of the restrictions that governed the development of sound synthesis methods in the past, and, in particular, those based on physical modeling of musical instruments. Even relatively complex models can now produce sound output in something approaching real time, if not real time itself. As an example, various models of strings and 2-D percussion instruments, simulated using direct time domain methods, are presented here. Various issues are discussed, including interconnections of various vibrating objects, extensions of percussion instruments involving acoustic ‘‘preparation,’’ the modeling of nonlinearities, multichannel output, algorithmic complexity, and operation counts, as well as current work towards developing real time implementations. Sound examples are presented.
