BSS Oracle

A toolbox to compute oracle estimators for source separation


by E. Vincent, R. Gribonval and Mark D. Plumbley


Purpose

BSS Oracle is a Matlab toolbox to evaluate the best performance achievable by a class of source separation algorithms in an evaluation framework where reference source signals are known. In other words, it computes the best demixing filters or the best time-frequency masks for a given mixture signal.

BSS Oracle implements oracle estimators for four classes of separation algorithms:

What it cannot do

BSS Oracle cannot separate sources blindly: it needs reference source signals to select the best separation parameters.
