SoundSpaces is a realistic acoustic simulation platform for audio-visual embodied AI research. From audio-visual navigation, audio-visual exploration to echolocation and audio-visual floor plan reconstruction, this platform expands embodied vision research to a broader scope of topics.

Motivation

Moving around in the world is naturally a multisensory experience, but today's embodied agents are deaf---restricted to solely their visual perception of the environment. We introduce audio-visual navigation for complex, acoustically and visually realistic 3D environments. We further build SoundSpaces: a first-of-its-kind dataset of audio renderings based on geometrical acoustic simulations for two sets of publicly available 3D environments (Matterport3D and Replica), and we instrument Habitat to support the new sensor, making it possible to insert arbitrary sound sources in an array of real-world scanned environments.

Installation

Follow the step-by-step installation guide to install the repo.

Usage

This repo renders audio-visual observations with high acoustic and spatial correspondence. It supports various visual-acoustic learning tasks, including audio-visual embodied navigation, acoustics prediction from egocentric observations, etc. In this repo, we provide code for training and evaluating audio-visual navigation agents. For other downstream tasks, please check out each paper's respective repo, e.g., visual acoustic matching and audio-visual dereverberation.

Below we show some example commands for training and evaluating AudioGoal with depth sensor on Replica.

  1. Validation (evaluate each checkpoint and generate a validation curve)
python ss_baselines/av_nav/run.py --run-type eval --exp-config ss_baselines/av_nav/config/audionav/replica/val_telephone/audiogoal_depth.yaml --model-dir data/models/replica/audiogoal_depth
  1. Test the best validation checkpoint based on validation curve

SoundSpaces 1.0

We provide acoustically realistic audio renderings for Replica and Matterport3D datasets. The audio renderings exist in the form of pre-rendered room impulse responses (RIR), which allows users to convolve with any source sounds they wish during training. See dataset for more details.
Note that we do not open source the rendering code at this time.

SoundSpaces 2.0

SoundSpaces 2.0 is a fast, continuous, configurable and generalizable audio-visual simulation platform that allows users to render sounds for arbitrary spaces and environments. As a result of rendering accuracy improvements, the rendered IRs are different from SoundSpaces 1.0. Check out the jupyter notebook for a quick tutorial. The documentation of the APIs can be found here.
