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

Wideband Relative Transfer Function (RTF) Estimation Exploiting Frequency Correlations This implementation estimates the relative transfer functions (RTFs) for beamforming applications taking spectral correlations into account. Software, Feb 2025
