# AcoustiTrace RT60 Evaluator

This repository contains the learned visual RT60 component used by
[AcoustiTrace](https://leader-sheng.github.io/AcoustiTrace/), an audio-visual
benchmark for diagnosing acoustic plausibility in generated videos.

The checkpoint estimates scene-consistent reverberation time at 500 Hz from
visual acoustic cues. It contains a LoRA adapter for
[`Qwen/Qwen3-VL-8B-Instruct`](https://huggingface.co/Qwen/Qwen3-VL-8B-Instruct)
and a Sabine-guided continuous physics head. It does **not** include a copy of
the Qwen3-VL base model.

## Use with AcoustiTrace

```bash
git clone https://github.com/Leader-sheng/AcoustiTrace.git
cd AcoustiTrace

python scripts/download_weights.py \
  --repo-id Missouter/AcoustiTrace-RT60 \
  --local-dir checkpoints/acoustitrace-rt60

python scripts/verify_checkpoint.py checkpoints/acoustitrace-rt60
```

The frozen base model is downloaded separately from
`Qwen/Qwen3-VL-8B-Instruct`. Full evaluator setup and end-to-end commands are
provided in the AcoustiTrace repository.

## Training sources and license

The RT60 supervision combines Matterport3D RGB-D observations, SoundSpaces 2.0
room-acoustic simulation, and absorption coefficients from the PTB Room
Acoustics Absorption Coefficient Database. No upstream training data is
included in this repository.

The model artifacts are available for non-commercial academic and research
use under the terms in [LICENSE](LICENSE). In particular, use remains subject
to the Matterport3D Academic Use Terms. The Qwen3-VL base model is separately
licensed under Apache-2.0.

## Scope

This model is released as the visual RT60 evaluator for AcoustiTrace. Its
outputs are diagnostic estimates for benchmark evaluation rather than direct
room-acoustic measurements.
