Visualization and Manipulation of 3D Digital Waveguide Structures for Sound Experimentation

1D and 2D digital waveguides are already established as important elements in physical modeling constructions. This paper describes a program which has been developed for sound experimentation using three dimensional digital waveguide structures. Arbitrary waveguide structures may be created and displayed in three dimensions. They may be rotated and viewed in a number of visualization modalities. Acoustic impulses may be applied to any element within the waveguide structure through the use of a `virtual' hammer. A `virtual' microphone may then be positioned to determine the acoustic response at any other point within the waveguide structure. Impulse sequences may be read and written to sound les at a sampling rate of 44100Hz.
