In this paper, we address the issue of underdetermined source separation of I nonstationary audio sources from a J -channel linear instantaneous mixture (J <; I). 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) joint analysis of each source signal and mixture signal enables to select the subset of sources (among I ) leading to the best separation results in each… CONTINUE READING
