# Pre-Computing Geometry-Based Reverberation Effects for Games

## One-sentence takeaway

Tsingos AES 2009: precompute geometry-based reverberation *for games* — bake late energy from the level, play it as a send.

## Why it matters here

Designers will not run FDTD. This AES Audio for Games talk is the 'precompute a reverb volume from the mesh' recipe (Crytek/Tsingos-era thinking). Anoptic: baked late tail + runtime early GA/wave, same split as Vorländer 1989.

## Key ideas

- **Geometry → reverb params/IRs** at design time.
- **AES 35th Audio for Games 2009.** elib 15164; no DOI in harvest.
- **Game-audio.** Not a JASA theory paper.
- **Late field emphasis.** Early reflections may still be runtime.

## Caveats

AES paywall-ish e-lib. Precompute ≠ dynamic destruction. Not FDN (cheap recursive) and not Triton wave (different bake).
