jeanlouis durrieu Institut TELECOM, TELECOM ParisTech / CNRS LTCI durrieu@enst.fr average computational time: about 200s per second of excerpt on Core2 2.66 GHz, unsupervised algorithm suited for de-soloing applications, stereo source separation method version based on Durrieu et al, \"AN ITERATIVE APPROACH TO MONAURAL MUSICAL MIXTURE DE-SOLOING\", submitted to ICASSP09. Unvoiced parts of the vocals are not separated with this version (contrary to the other submitted algorithm). Better run time essentially due to better Matlab implementation.
