<p>PROBLEM TO BE SOLVED: To prevent useless topmusic information from being recorded in a pause, etc., of performance and to record the topmusic information on an optimum position with simple operation. SOLUTION: A trigger generation circuit 23 generates a trigger signal when a level discrimination circuit 21 discriminates that a signal level of an audio signal exceeds a threshold level. A digital signal processing circuit 13 adds a start ID to the audio signal when the trigger signal is generated to perform the processing converting it to a prescribed format. Then, a rotary head 15 records the audio signal on a magnetic tape 20. Then, the level discrimination circuit 21 stops the comparative discrimination between the signal level and the threshold level of the audio signal.</p> |
