ABSTRACT:
An apparatus having a microphone, an analog to digital converting circuit, a semiconductor memory an, input device, and a controller, wherein the analog to digital converting circuit converts an output signal from the microphone into a digital signal. The semiconductor memory stores the output signal from the analog to digital converting circuit, and the input device carries out input of a record start and a record end. The controller, according to the input from the input device, carries out control to start and stop writing into the semiconductor memory a digital signal from the analog to digital converting circuit. When the input device is operated and a predetermined time interval has passed, the controller starts writing the digital signal from the analog/digital conversion circuit into the semiconductor memory.
