ABSTRACT:
An audio signal recording/reproducing system is used in a time-lapse video tape recording device for time-lapse recording a video signal on a magnetic tape at predetermined time intervals. The audio signal recording/reproducing system comprises a memory which stores an audio signal and time-compresses the stored audio signal to output it as the time-compressed audio signal at one field period, and a magnetic head for recording the one-field period audio signal on the magnetic tape. Each of the audio signal recording tracks recorded on the magnetic tape is arranged between two adjacent video signal recording tracks. The audio signal recorded on the magnetic tape is read out by the magnetic head and stored in the memory again. The audio signal stored in the memory is expanded in its time-base to be reproduced as continuous sound.
