<p>PURPOSE:To omit the time required to perform the program searching of the voice tape of an original blank material by detecting the time point when the reproduction of the sound signal contained in the material is started and starting the storage of the sound signal. CONSTITUTION:A branching device 3 branches the voice output 2 of a reproducer 1 which reproduces the material of the CM sound signal for a tape recorder, etc. A sound signal detector 5 delivers a sound signal detecting signal 6. A control part 8 for audio file device triggers the signal 6 and delivers a disk control signal 9 to a disk device 10. While a sound signal 11 is supplied to a buffer memory via a voice amplifier 12 and an A/D conversion part 14. Then the voice data 18 is sent to the device 10 from the memory 16 when a control signal 17 is delivered from the part 8 by the interruption applied from the detector 5. The data 18 is written and stored by a disk control signal 9.</p> |
