<p><P>PROBLEM TO BE SOLVED: To prevent a level from being temporarily raised at the time of an attack and release. <P>SOLUTION: The delay time DT of a delay circuit 12 is made longer than attack control time AT so as to complete attack control when a sound signal to be inputted to a variable gain amplifier circuit 13 attacks. When the attack control is switched from attack control to release control, a value holding circuit 20 holds a control signal as long as time HT that is longer than the delay time DT so as to delay a release control start point than the release time of the sound signal to be inputted to a variable gain amplifier circuit 13. <P>COPYRIGHT: (C)2004,JPO</p> |
