In this page you can find two EM algorithms for simultaneous separation and diarision of multichannel convolutive audio mixtures. The algorithm on Icassp 2017 paper
[IEEXplore] [pdf] uses the Narrow-Band model to represent the multichannel mixture in the STFT domain. The algorithm on Waspaa 2017 paper [IEEXplore] [pdf] uses the Spatial Covariance model of Duong et. al. to represent the multichannel mixture.
