about

Project Acoustics is a wave-based acoustics simulation system that bakes acoustic propagation into pre-computed data files. It models occlusion, obstruction, portalling, and reverberation using physics-based wave simulation during an offline baking process, then provides runtime queries for interpolated acoustic parameters.

The system uses the Triton engine for voxel-free interpolation and supports multiple ACE files simultaneously. It includes HRTF processing validated through FLEX listening tests published in the Journal of the Acoustic Engineering Society. Runtime performance remains efficient by querying pre-baked simulations rather than computing wave propagation in real-time.

Integrations provide spatial reverb, custom impulse responses, and parameter exposure to engine-native systems. The tool handles large worlds through double-precision mesh parsing and supports both middleware and engine-native audio pipelines.
