CA 2755834

A device and method for manipulating an audio signal comprises a windower (102) for generating a plurality of consecutive blocks of audio samples, the plurality of consecutive blocks comprising at least one padded block of audio samples, the padded block having padded values and audio signal values, a first converter (104) for converting the padded block into a spectral representation having spectral values, a phase modifier (106) for modifying phases of the spectral values to obtain a modified spectral representation and a second converter (108) for converting the modified spectral representation into a modified time domain audio signal.

L'invention concerne un dispositif et un procédé permettant le traitement d'un signal audio, qui utilisent un dispositif de fenêtrage (102) destiné à générer une pluralité de blocs consécutifs d'échantillons audio, ladite pluralité de blocs consécutifs comportant au moins un bloc d'échantillons audio rempli, ledit bloc rempli ayant des valeurs de remplissage et des valeurs de signaux audio, un premier convertisseur (104) destiné à convertir le bloc rempli en représentation spectrale possédant des valeurs spectrales, un modificateur de phases (106) destiné à modifier les phases des valeurs spectrales pour obtenir une représentation spectrale modifiée et un second convertisseur (108) destiné à convertir la représentation spectrale modifiée en signal audio à domaine temporel modifié.
