AUDIO CHANNEL EXTRACTION USING INTER-CHANNEL AMPLITUDE SPECTRA

摘要

FIELD: information technology.;SUBSTANCE: 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 creates multiple audio channels which are not only linear combinations of input channels, and thus can than be used, for example, in combination with a blind source separation (BSS) algorithm.;EFFECT: efficient extraction of specific initial sources from their linear mix.;19 cl, 16 dwg
