We address the problem of instantaneous, underdetermined audio source separation by time-frequency masking. Using oracle estimators, we determine experimental upper performance bounds, by assuming that we have reference sources available, and that we know, or have estimated, the mixing structure. Oracle estimation of four musical sources from two-channel mixtures demonstrates a potential for SDR improvements of up to 12.7 dB, compared to semi-blind methods. We also show that using adaptivedoi:10.1109/icassp.2008.4517541 dblp:conf/icassp/NesbitP08 fatcat:ezhu666rfney3hwzqglbnt7dxe
