Source separation with one ear : proposition for an anthropomorphic approach
Abstract : We present an example of an anthropomorphic approach, in which auditory-based cues are combined with temporal correlation to implement a source separation system. The auditory features are based on spectral ...
Performance of three acoustical methods for localizing whales in the Saguenay - St. Lawrence Marine Park
Abstract : Three algorithms are explored to localize fin whale calls recorded from a large-aperture hydrophone array deployed in the Saguenay—St. Lawrence Marine Park. The methods have to cope with varying sound speed in ...
Wavelet speech enhancement based on time-scale adaptation
Abstract : We propose a new speech enhancement method based on time and scale adaptation of wavelet thresholds. The time dependency is introduced by approximating the Teager Energy of the wavelet coefficients, while the ...
