PURPOSE:To attain sound recording/reproduction without requiring the operation of rewinding and reproduction by detecting the designation of sound recording from a sound recording designation means, designating sequentially write to a storage means, and designating the reading sequentially from the 1st address to the final stored address with the write designation of the stored content after the end of write designation. CONSTITUTION:A sound signal applied to an input terminal IN is applied to an A/D converter 11, where the signal is converted into a sound signal data and the data is applied to an RAM2. A program controlling a CPU21 is written in an ROM22, the CPU21 reads an output of a detection circuit 14 and a setting data of a reproduction number setting device 19 via an input port 24 according to the program in the ROM22 as required, transmits/receives data with the RAM23, executes operation and comparison, and transmits a convertion designation signal to the A/D converter 11 via an output port 25, a write designation signal, a read designation signal and an address signal to the RAM2 and a conversion designation signal to a D/A converter 13 as required according to the result of comparison and operation. |
