Phase-based informed source separation for active listening of music

Abstract : This paper presents an informed source separation technique of monophonic mixtures. Although the vast majority of the sepa- ration methods are based on the time-frequency energy of each source, we introduce a new approach using solely phase informa- tion to perform the separation. The sources are iteratively recon- structed using an adaptation of the Multiple Input Spectrogram In- version (MISI) algorithm from Gunawan and Sen. The proposed method is then tested against conventional MISI and Wiener filter- ing on monophonic signals and oracle conditions. Results show that at the cost of a larger computation time, our method outper- forms both MISI and Wiener filtering in oracle conditions with much higher objective quality even with phase quantization.
