<P>PROBLEM TO BE SOLVED: To apply an audio effect to a signal with an instantaneous event. <P>SOLUTION: A signal operating device for operating an audio signal with an instantaneous event includes an instantaneous event signal removing unit 100, a signal processing unit 110 and a signal inserting unit 120. The signal operating device inserts a time portion into a processed audio signal at a signal position where the instantaneous event is removed by the instantaneous event signal removing unit 100. As a result, the operated audio signal includes an instantaneous event that is unaffected by processing. At this point, vertical coherence of instantaneous event is maintained because the vertical coherence is not destroyed by the processing executed in the signal processing unit 110. <P>COPYRIGHT: (C)2012,JPO&INPIT |
