# Triton: Practical Pre-Computed Sound Propagation for Games and Virtual Reality

## One-sentence takeaway

Triton: the practical Project Acoustics bake that shipped in games/VR — precomputed wave parameters as an engine feature, not a paper demo.

## Why it matters here

This is the 'call the middleware' card for Anoptic: Raghuvanshi/Tennant/Snyder 2017 ASA is the *productization* of 1669–1671. Gears-era Microsoft spatial audio. Use when you want the shipping contract, not the SIGGRAPH encoding math.

## Key ideas

- **Engine-oriented bake.** Design-time wave simulation → runtime parameter volumes designers can place.
- **Games and VR.** Harvest: game/engine-oriented, rel=17.
- **Lineage.** ARD 2009 → precomputed wave 2010 → parametric 2014/2018 → Triton 2017.
- **ASA 2017 abstract / JASA.** Short paper; the systems view of Project Acoustics.

## Caveats

Abstract-length vs the TOG encoding papers. Static-world bake; live destruction needs portals (1735) or 2D wave (1754). Not GSound (ray/UTD), not MagLS.
