Abstract

We present a method for simulating reverberation in real-time using arbitrary object shapes. This method is an extension of digital plate reverberation where a dry signal is filtered through a physical model of an object vibrating in response to audio input. Using the modal synthesis method, we can simulate the vibration of many different shapes and materials in real time. Sound samples are available at the following website: http://cynthia.code404.com/dafx-audio/. and apply forces using the discrete convolution integral method as described in [4] and [5]. We implement this reverberation as an effect plug-in that takes an audio stream as the input and produces the sound of the object vibration as the output. The main contributions of this paper are to extend the use of the modal synthesis and the discrete convolution integral for the rapid simulation of the motion of objects in response to arbitrary loading profiles. We give examples of using this technique for the deformation of linear shell models of simple and complex shapes in a real-time synthesis environment.
