Multi-Microphone

Joint Alternating Least-Squares-Based Microphone Array Parameter Estimation for A Single-Source Reverberant and Noisy Acoustic Scenario

This algorithm can be used to jointly estimate the source’s RTF, and the PSDs of the early reflections, the late reverberation and the ambient noise at low complexity.

Software, Feb 2025

Multimicrophone Signal Parameter Estimation in A Multi-Source Noisy Reverberant Scenario

This algorithm can be used in the more general scenarios where multiple sources, late reverberation and noise exist concurrently. The algorithm can be used to estimate the relative transfer functions (RTFs) of the point sources (both target and interferers) and individual power spectral densities (PSDs) of the sources and the late reverberation.

Software, Feb 2025

Joint Maximum Likelihood Estimation of Microphone Array Parameters for a Reverberant Single Source Scenario

Matlab software for estimating the ATF, source PSD, and late reverberation PSD for a single source scenario.
