Infuriating Nonlinear Reverberator
Miller Puckette · University of Michigan Library Repository · 2011
A ceramic tile or other small rigid object is attached to a contact microphone, and any resonances of the physical system are filtered out using linear predictive analysis. The resulting audio signal is fed into a nonlinear reverberator to simulate a variety of real or fanciful percussion instruments. The result is a highly expressive and playable electronic percussion instrument that is both easy and inexpensive to build. The effects of various design parameters of the nonlinear reverberator on the resulting sound are discussed.
