SIGGRAPH 2018 Parametric Directional Coding for Precomputed Sound Propagation

Nikunj Raghuvanshi and John Snyder. 2018. Parametric Directional Coding for Precomputed Sound Propagation. ACM Trans. Graph. 37, 4, Article 108 (August 2018), 14 pages. Convincing audio for games and virtual reality requires modeling directional propagation effects. The initial sound s arrival direction is particularly salient and derives from multiplydiffracted paths in complex scenes. When source and listener straddle occluders, the initial sound and multiplyscattered reverberation stream through gaps
