Add to ORKGIn this paper we propose a simple time-frequency Gaussian model of audio signals that allows for separation of possibly underdeter-mined and noisy linear instantaneous mixtures. An efcient EM algorithm is proposed to estimate the mixing matrix, the noise co-variance and covariances of the source t-f coefcients over a cho-sen frame/subband tiling of the time-frequency domain. Results are given on 4 4 and 3 4 noisy mixtures of audio sources. 1
