2011 Signal Separation Evaluation Campaign
Under-determined speech and music mixtures
Test2 database

For details about each algorithm, click on "Algorithm".
Performance are evaluated using SIR/SDR/SAR metrics defined by BSS_EVAL and OPS/TPS/IPS/APS defined in PEASS 2.0.

SiSEC2010 submissions are also evaluated with PEASS 2.0 in the detailed result tables, to compare the PEASS results of SiSEC2010, where the PEASS version was 1.0.
