| Abstract(in English) | Proposed is a processing scheme of Blind Source Separation (BSS) employing frequency-domain Independent Component Analysis (f-ICA) to a vector consisting of time series of adjacent frequency components, contrasting with Permutation-Free ICA (PF-ICA) applying f-ICA to a vector consisting of all the frequency components. The proposed method is named Multi-Bin ICA (MB-ICA). It can treat directionality of frequency characteristics of the sound field, while PF-ICA proposed by Di Persia cannot treat directionality of frequency characteristics. Its performance is confirmed by comparing with those of ordinary ICA and PF-ICA for room environments of almost equal directionality and of forcedly asymmetrical directionality in the room characteristics. |
