In this paper, we address the issue of underdetermined source separation of non-stationary audio sources from a stereo (i.e. 2-channel) linear instantaneous mixture. This problem is addressed with a specific coder-decoder configuration. At the coder, source signals are assumed to be available before the mixing is processed. A time-frequency (TF) analysis of each source enables to select the one or two predominant sources (among I≫2) in each TF region, and a corresponding source(s) index code is… CONTINUE READING
