about

Neural Acoustic Fields is a research implementation that models acoustic propagation in physical scenes as a continuous implicit function. By treating sound propagation as a linear time-invariant system, NAF learns to map any emitter-listener location pair to a neural impulse response that can be applied to arbitrary audio sources.

The system enables continuous spatial audio rendering for listeners at any position in a scene, including novel locations not seen during training. NAF learns magnitude-only representations (using random phase similar to Image2Reverb) and demonstrates how acoustic structure emerges as a byproduct of learning spatial sound propagation. The learned representations can also improve visual learning tasks with sparse views.

This is research code from a NeurIPS 2022 paper, providing training and evaluation pipelines for learning acoustic fields from 3D scene data. It includes baseline comparisons against codec-based interpolation methods (AAC-LC, Opus) and tools for analyzing spectral accuracy, T60 error, and learned feature representations.
