<P>PROBLEM TO BE SOLVED: To sufficiently suppress impact sound in a deteriorated signal by reducing discontinuity of a signal caused by a phase. <P>SOLUTION: A signal processing method includes: suppressing impact sound in the deteriorated signal; detecting the impact sound in the deterioration signal therefor; and processing phase information of detected impact sound with the phase information of signals other than the impact sound in the deteriorated signal so that a change amount of the phase information is smaller. <P>COPYRIGHT: (C)2011,JPO&INPIT |
