| Zusammenfassung: | A computing part computes a correlation coefficient representing a level of correlation among acoustic signals for a plurality of channels. A filtering part smoothes a time variation of the correlation coefficient computed. A center component reducer reduces a correlation component that is common in the acoustic signals by using the correlation coefficient. Then, the correlation component extracted by the reducer is reduced from each of the acoustic signals. |
