- W193133003 abstract "This paper presents a blind source separation process for convolutive mixtures of audio sources. Here undetermined condition that is few microphones than sources has been considered as a mixing model. By an expectation– maximization (EM) algorithm the separation operation is performed in the frequency domain. The T-F masking separation is made use which is a powerful approach for the separation of underdetermined mixtures, especially for the separation of single-channel mixtures. Even under reverberant conditions the process enables to attain a good separation. From the experimental results, separated signals SDR values of speech mixtures is obtained in the range of 7.5dB while for music mixtures in the range of 2.9dB. It can be concluded from these values that separation of speech mixtures is better than music mixtures. General Terms Blind Source Separation, Convolutive mixing" @default.
