装置。[Claims for Utility Model Registration] A delay section that delays an audio signal by a predetermined time and outputs it, a mute section that mutes the output signal of the delay section, and a point at which the original audio signal crosses O volts before passing through the delay section. a zero-cross detection section that detects the delay time of the audio signal; a delay time change instruction section that instructs to change the delay time of the audio signal; and a delay time change instruction section that detects the time from when the original audio signal zero-crosses when an instruction to change the delay time from d1 to d2 is given. 1. An audio signal delay device comprising: a control unit that monitors the elapse of time d1, applies mute after time d1 has elapsed, and cancels the mute after time d2 has elapsed after the original audio signal crosses zero.
