Abstract

A digital artificial reverberation algorithm is presented, based on a full-time domain simulation of plate vibration. As such it may be considered to be a physical model plate reverberation, a popular means of processing audio signals in the days of analog production. A small number of parameters are available to the user, to be used to tune the plate response, in a means analogous to that for the acoustic plate reverberation unit. Such parameters include stiffness, aspect ratio, tension, and two-parameter loss. A variety of other possibilities are opened up, including multichannel input and output, possibly over time-varying locations, and various types of boundary termination. The complete numerical method is presented, along with a discussion of implementation details and computational complexity (which is near real time). Numerical results and sound examples are also presented.
