Despite its popularity, multichannel source demixing is intrinsically limited in real-world applications due to the model mismatch between the convolutive mixing model and the actual recordings. Varying number of sources, reverberation, diffuseness and spatial changes are common uncertainties that need to be handled. Post-processing is commonly adopted to(More)
Acoustic source time-difference of arrivals (TDOAs) estimation is a basic task required by source localization and separation techniques. Standard wide-band methods, e.g. the GCC-PHAT, estimate the TDOAs by evaluating the cross-correlation at multiple time lags and performing a direct-search of the global maximum. A more convenient formulation is to model(More)
