# Scattering Delay Networks for Artificial Reverberation

## One-sentence takeaway

Scattering Delay Networks: a physically structured FDN whose delays/scattering come from a room *graph* (walls as nodes) — cheap geometric-ish reverb.

## Why it matters here

Full GA is heavy; a random FDN ignores layout. De Sena/Hacıhabiboğlu/Cvetković/Smith 2015 TASLP build an SDN from a box/graph of surfaces — the parametric reverb you can still run on a game thread. Anoptic hallway vs hangar: change the delay graph, not a 2 s IR.

## Key ideas

- **Room as scattering network.** Nodes ~ walls/patches; edges ~ delays.
- **FDN cousin with geometry.** Harvest reverb-parametric.
- **IEEE TASLP 2015.** JOS among authors.
- **Realtime recursive.** Contrast convolution of baked IRs.

## Caveats

Coarse geometric abstraction (not diffraction, not modes). Forced parametric. Not Triton. 2015.
