From Blind Source Separation to Blind Source Cancellation in the Underdetermined Case: a New Approach Based on Time-frequency Analysis

Many source separation methods are restricted to non-Gaussian, stationary and independent sources. This yields some problems in real applications where the sources often do not match these hypotheses. Moreover, in some cases we are dealing with more sources than available observations which is critical for most classical source separation approaches. In this paper, we propose a new simple sourc...

Unison Source Separation

In this work we present a new scenario of analyzing and separating linear mixtures of musical instrument signals. When instruments are playing in unison, traditional source separation methods are not performing well. Although the sources share the same pitch, they often still differ in their modulation frequency caused by vibrato and/or tremolo effects. In this paper we propose source separatio...

Blind Spectral-GMM Estimation for Underdetermined Instantaneous Audio Source Separation

The underdetermined blind audio source separation problem is often addressed in the time-frequency domain by assuming that each time-frequency point is an independently distributed random variable. Other approaches which are not blind assume a more structured model, like the Spectral Gaussian Mixture Models (Spectral-GMMs), thus exploiting statistical diversity of audio sources in the separatio...

A new approach for blind source separation using time frequencydistributions

This paper deals with the problem of blind source separation which consists of recovering a set of signals from instantaneous linear mixtures of them. So far, this problem has been solved using statistical information available on the source signals. Here, we propose an approach for blind source separation based on time-frequency (t-f) signal representations. This approach is based on a `joint ...
