Volumetric modeling of acoustic fields in CNMAT´s sound spatialization theatre

A new tool for real time visualization of acoustic sound fields has been developed for a new sound spatialization theatre. The theatre is described and several applications of the acoustic and volumetric modeling software are presented. The visualization system described is a valuable tool for spatial sound researchers, sound engineers and composers using CNMAT´s sound spatialization theatre. Further work is in progress on the adaptation of better acoustic simulation methods (M. Monks et al., 1996) for more accurate display of the quality of the reverberant field. The room database will be automatically extracted from a model built with 3D modeling software. Volume visualization strategies are being explored to display sounds in spectral and impulse response form.
