# Adaptive impulse response modeling for interactive sound propagation

## One-sentence takeaway

Adaptive impulse-response modeling at I3D 2016: update encoded IRs interactively as the listener moves through a game scene.

## Why it matters here

Schissler & Manocha I3D 2016 is the engine-facing IR-adaptation paper (between GSound and 2017 multi-source). Anoptic: don't rebuild a 2 s IR every step — morph parameters, keep the convolution running (1091-style filters).

## Key ideas

- **Adaptive IR.** Time-varying filter as listener/source move.
- **I3D 2016.** Game/engine-oriented; harvest rel=21.
- **Geometric interactive stack.** UNC.
- **Runtime convolution** of a changing IR, not a static hall send.

## Caveats

Parameter morphing ≠ physically correct dynamic wave field. I3D short vs TOG. Not SDN/FDN (different reverb family).
