Abstract : This paper deals with audio source separation guided by multiple audio references. We present a general framework where additional audio references for one or more sources of a given mixture are available. Each audio reference is another mixture which is supposed to contain at least one source similar to one of the target sources. Deformations between the sources of interest and their references are modeled in a general manner. A nonnegative matrix co-factorization algorithm is used which allows sharing of information between the considered mixtures. We run our algorithm on music plus voice mixtures with music and-or voice references. Applied on movies and TV series data, our algorithm improves the signal-todistortion ratio SDR of the sources with the lowest intensity by 9 to 12 decibels with respect to original mixture.
