# Progressive perceptual audio rendering of complex scenes

## One-sentence takeaway

Progressive perceptual rendering: stream cluster refinements so complex scenes start cheap and add sources as budget allows (Moeck/Tsingos/Drettakis I3D 2007).

## Why it matters here

Tsingos 2004 clustering is a snapshot. I3D 2007 makes it progressive — important for GRID COMMAND when the audio thread has leftover ms. Harvest quality 10 despite being the 'progressive' leftover.

## Key ideas

- **Progressive clusters.** Coarse grouping first, split as time allows.
- **I3D 2007.** Game/engine-oriented.
- **INRIA perceptual audio.** Same family as 1714.
- **Masking-aware.** Don't spend budget on inaudible emitters.

## Caveats

Hysteresis/pops. Doesn't compute physics. 2007 hardware. Pair with Schissler 2017 for the tracer-side many-source problem.
