Inter-channel amplitude spectra are used to extract multiple audio channels from two or more audio input channels comprising a mix of audio sources. This approach produces multiple audio channels that are not merely linear combinations of the input channels, and thus can than be used, for example, in combination with a blind source separation (BSS) algorithm.

La présente invention concerne un spectre d'amplitude inter-canaux utilisé pour extraire plusieurs canaux audio à partir de deux canaux d'entrée audio ou plus, comprenant un mélange de sources audio. Cette approche produit plusieurs canaux audio qui ne sont pas des combinaisons simplement linéaires des canaux d'entrée et peuvent donc être utilisés, par exemple, en combinaison avec un algorithme de séparation de source aveugle (BSS).
