Abstract
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.
