A toolbox to compute oracle estimators for source separation

by E. Vincent and R. Gribonval


BSS_ORACLE is a MATLAB toolbox to evaluate the best performance achievable by a class of source separation algorithms in an evaluation framework where the true reference sources are known.

What it can do / what it cannot do

BSS_ORACLE can only compute oracle estimates when the true reference sources are known. In no way it provides a method to separate the sources blindly: it needs to know the reference sources to select the best separation algorithm (the oracle) within a given class.
