Abstract:
1. A recording and/or reproducing apparatus comprising: a microphone; an automatic gain control circuit for adjusting an output signal from said microphone; an analog to digital converting circuit for converting an output signal from said microphone into a digital output signal; a semiconductor memory for storing said digital output signal from said analog to digital converting circuit; a digital to analog converting circuit for converting a digital signal read from said semiconductor memory into an analog output signal; an input device operable by a user of said apparatus for entering at least a recording start mode; a controller for controlling in response to an input from said input device a writing of said digital output signal from said analog to digital converting circuit into said semiconductor memory and a reading of a stored digital signal from said semiconductor memory; and a cabinet in which said microphone, said analog/digital converting circuit, said digital/analog converting circuit, and said input device are arranged, wherein said semiconductor memory includes at least two files and said output signal from said microphone converted by said analog to digital converting circuit into said digital output signal is written in one of said at least two files file as specified by said input device, said controller controls a start of said writing of said digital converting circuit into said semiconductor memory in response to an input from said input device, and after said input device is operated and a predetermined time interval has lapsed said controller controls the start of said writing into said semiconductor memory of said digital output signal from said analog to digital converting circuit, and wherein said controller comprises a switch for entering a recording start mode; and said controller starts writing into said storage device when said predeterming time interval has passed after said switch is initially operated, and terminates writing into said storage device said digital output signal from said analog to digital converting circuit at a time point equal to said predetermined interval before an end of said digital output signal occurs after said switch is subsequently operated.
