Title:
METHOD AND APPARATUS FOR SOUND TRACING FOR ENHANCEMENT OF SOUND PROPAGATION PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2022/191356
Kind Code:
A1
Abstract:
The present invention relates to a method and apparatus for sound tracing for the enhancement of a sound propagation performance. The method comprises: a setup processing step of setting up ray information; a ray generation step of generating a sound ray; a traversal/intersection test step of generating hit triangle information; a propagation path validation (PPV) step of searching for a sound path; a guide plane sort step of generating and sorting a guide plane; a reverb geometry collect/reverb plane sort (RGC/RPS) step of generating and sorting a reverb plane; and an impulse response calculation step of calculating an impulse response (IR) and storing the calculated IR in a valid path buffer.
