<p>PURPOSE:To detect a position on a cassette tape on the basis of position data read similarly and to reproduce data on the tape from the point, by attaining audio recognition by referring to previously read-in data at the point in time when a voice is inputted by an operator. CONSTITUTION:A tape, after being set, is rewound by muCPU10 via interface circuit 8 and counter 2 is reset to zero. Digital data of the title of a musical composition and its beginning of singing recorded at the head of the tape are stored in RAM12 via demodulating circuit 7. Analog data are stored in RAM12 by way of A/D converter 15 and the buffer memory. When a sound is inputted from microphone 13 in this state, it is stored in RAM12 via A/D converter 15 and buffer memory 16. According to a program in ROM11, muCPU10 compares both data in RAM12 to find the address of the musical composition and feeds rapidly the tape up to the position through interface circuit 8.</p> |
