Welcome to the official code repository for "Novel-View Acoustic Synthesis from 3D Reconstructed Rooms".
This project estimates the sound anywhere in a scene containing multiple unknown sound sources, hence resulting in novel-view acoustic synthesis, given audio recordings from multiple microphones and the 3D geometry and material of a scene.

Installation: SoundSpaces

Follow our Step-by-Step Installation Guide for rendering room impulse responses (RIRs) and images in Matterport3D rooms using SoundSpaces.

Quickstart: Demo

Refer to the Demo Guide for instructions on data generation, dry sound estimation using our model, and novel-view acoustic rendering.

Download the Pretrained Model

Download our pretrained model and place it in the nvas3d/assets/saved_models/default/checkpoints/ directory.

Launch the Demo

To get started with the full pipeline quickly:

bash demo/run_demo.sh

Training

After Training Data Generation, start the training process with:

python main.py --config ./nvas3d/config/default_config.yaml --exp default_exp
