Parametric Directional Coding for Precomputed Sound Propagation
Convincing audio for games and virtual reality requires modeling directional propagation effects. The initial sound’s arrival direction is particularly salient and derives from multiply-diffracted paths in complex scenes…

Gears of War 4, Project Triton: Pre-Computed Environmental Wave Acoustics
In this 2017 GDC talk, Microsoft’s Nikunj Raghuvanshi and John Tennant discuss both the technical and design aspects of Project Titan, a new audio system that robustly models complex wave phenomena such as diffraction…

Parametric Wave Field Coding for Precomputed Sound Propagation
The acoustic wave field in a complex scene is a chaotic 7D function of time and the positions of source and listener, making it difficult to compress and interpolate. This hampers precomputed approaches which tabulate impulse…

Wave-Based Sound Propagation in Large Open Scenes using an Equivalent Source Formulation
We present a novel approach for wave-based sound propagation suitable for large, open spaces spanning hundreds of meters, with a small memory footprint. The scene is decomposed into disjoint rigid objects. The free-field acoustic…

Sound Synthesis for Impact Sounds in Video Games
We present an interactive system for synthesizing high quality, physically based audio on current video game consoles. From a recorded impact sound, we compute a modal model, which we use to synthesize variations of the sound…

Precomputed Wave Simulation for Real-Time Sound Propagation of Dynamic Sources in Complex Scenes
We present a method for real-time sound propagation that captures all wave effects, including diffraction and reverberation, for multiple moving sources and a moving listener in a complex, static 3D scene…

Aerophones in Flatland: Interactive Wave Simulation of Wind Instruments
We present the first real-time technique to synthesize full bandwidth sounds for 2D virtual wind instruments. A novel interactive wave solver is proposed that synthesizes audio at 128,000Hz on commodity graphics cards. Simulating…
