# Framework for Real-Time Auralization in Architectural Acoustics

## One-sentence takeaway

Noisternig/Katz/Siltanen/Savioja 2008: a *framework* for real-time auralization in architectural acoustics (Acta Acustica) — pipeline, not one tracer.

## Why it matters here

Systems-architecture card: how to connect GA/beam tracing, DSP, and spatialization for architects. Anoptic tools/debug: this pipeline diagram (and the 2008 Ambisonics sibling 1742).

## Key ideas

- **Framework.** Blocks: geometry → IR/paths → spatializer → headphones/speakers.
- **Acta Acustica 2008.** Harvest auralization/interactive; 25 cites.
- **Aalto + Katz.** Same names as ART and binaural.
- **Realtime architectural** target (design, not FPS HUD).

## Caveats

Framework paper; algorithms live in the cited tracers. 2008. Not a game engine (that's GSound/Triton).
