Informed Acoustic Source Separation

Acoustic source separation has received a great interest from the research community but the problem remains challenging in the undetermined setting (when the number of sources I is less than the number of channels J), including the single-channel case (I = 1), and for convolutive mixtures. It is now quite clear that source separation performances strongly depend on the amount of available prior information about the sources and the mixing process one can introduce in the source separation algorithm. The so-called informed source separation methods then appear to be particularly attractive.

This special issue will also build on the success of the recent (double) special session at Eusipco 2012 on the very same topic.

    On the use of a spatial cue as prior information for stereo sound source separation based on spatially weighted non-negative tensor factorization

    This paper proposes a new method to enhance the performance of non-negative tensor factorization (NTF), one of the most prevalent source separation techniques nowadays. The enhancement is mainly achieved by in...

    Perceptually controlled doping for audio source separation

    The separation of an underdetermined audio mixture can be performed through sparse component analysis (SCA) that relies however on the strong hypothesis that source signals are sparse in some domain. To overco...

    Nonnegative signal factorization with learnt instrument models for sound source separation in close-microphone recordings

    Close-microphone techniques are extensively employed in many live music recordings, allowing for interference rejection and reducing the amount of reverberation in the resulting instrument tracks. However, des...
