PROBLEM TO BE SOLVED: To provide a reverberating circuit and an audio device using it which can obtain good adjustment feeling of reverberation. SOLUTION: A microphone signal MC from a microphone 11 is amplified by an amplifier 12 and supplied to a mixing section 40. A microphone output signal MEB outputted from the mixing section 40 is supplied to a delay section 18. The signal MEB is delayed by the delay section 18 and supplied to a reverberation quantity adjuster 19 as a delay signal DLC. A reverberation signal ECB obtained by adjusting a signal level of the signal DLC by the adjuster 19 is supplied to the mixing section 40, mixed with the microphone signal MC, and the microphone output signal MEB is generated. By making reverberation small by the adjuster 19, an attenuation rate of reverberation is made large and a continuation time of reverberation is made short, and by making reverberation large, an attenuation rate of reverberation is made small and a continuation time of reverberation is made long, then, good adjustment feeling of reverberation can be obtained. |
