置。a delay unit that repeatedly delays an input audio signal to form an echo component; a mixing unit that mixes and adds the echo component to the input audio signal to output a mixed audio signal having an echo effect; and a mixing unit that detects the level of the input audio signal. Basically, it includes a detection section that outputs a detection signal during a low level period when the input audio signal is below a predetermined level and a non-input period of the input audio signal, and a detection section that mutes the output from the delay section to the mixing section using the detection signal. An electronic echo device equipped with a muting section that performs muting.
