Summary

Barak A. Pearlmutter and Anthony M. Zador propose an algorithm for separating spatially localized acoustic sources in a noisy environment using the monaural head-related transfer function (HRTF).
The algorithm assumes each source has a unique position in space and is subject to a different linear filter, and incorporates prior knowledge of weak statistical regularities in the sources.
Sources are represented sparsely in an overcomplete basis, and the algorithm solves an underdetermined system using L1-norm optimization.
The goal is to recover the underlying sources from the observed signal using knowledge of the directional filters, and the algorithm can be extended to make predictions about neural representations required to separate acoustic sources.
