Abstract
A computer-implemented method is provided for multi-source sound localization. The method includes extracting, by a hardware processor, spectral features from respective pluralities of microphones comprised in each of two or more microphone arrays. The method further includes forming, by the hardware processor, respective sets of pairs of the spectral features from the respective pluralities of microphones within each of the two or more microphone arrays by rearranging and duplicating the spectral features from the respective pluralities of microphones included in each of the two or more microphone arrays. The method also includes inputting, by the hardware processor, the respective sets of pairs of the spectral features into a neural network to encode the spectral features into deep features and decode the deep features to output from the neural network at least one location representation of one or more sound sources.
