Sparse representations in audio & music: from coding to source separation [PDF]

, 2010
—Sparse representations have proved a powerful toolin the analysis and processing of audio signals and already lieat the heart of popular coding standards such as MP3 andDolby AAC.

Speech enhancement via combination of Wiener filter and blind source separation [PDF]

, 2011
Automatic speech recognition (ASR) often fails in acoustically noisy environments. Aimed to improve speech recognition scores of an ASR in a real-life like acoustical environment, a speech pre-processing system is proposed in this paper, which consists ...

Blind source separation to enhance spectral and non-linear features of magnetoencephalogram recordings:Application to Alzheimer's disease [PDF]

, 2009
This work studied whether a blind source separation (BSS) and component selection procedure could increase the differences between Alzheimer's disease (AD) patients and control subjects' spectral and nonlinear features of magnetoencephalogram (MEG ...

Blind and semi-blind source separation

, 2007
After a brief state-of-the-art description, we introduce the fundamental concepts of independent component analysis, which is the reference technique we used to solve the blind- or semi-blind source separation problem for astrophysical images. The specific aspects of this problem are then presented, and the results we obtained with some specific ...

Combining Superdirective Beamforming and Frequency-Domain Blind Source Separation for Highly Reverberant Signals

EURASIP Journal on Audio, Speech, and Music Processing, 2010
Frequency-domain blind source separation (BSS) performs poorly in high reverberation because the independence assumption collapses at each frequency bins when the number of bins increases.

Sparse separation of sources in 3D soundscapes [PDF]

, 2010
A novel blind source separation algorithm applicable to extracting sources from within 3D soundscapes is presented. The algorithm is based on constructing a binary mask based on directional information. The validity of filtering using binary masked based
