ABSTRACT:
A method and device for coordination of a signal to a sound event stored on a magnetic tape or the like, particularly for signalizing and locating the sound event. A tape drive device is operatively coupled with a counter. The sound playback is started, and when the user recognizes the sound event, the counter, in functional relationship with the tape transport, is activated. After a certain time interval or upon the occurrence of a counter value, the magnetic tape is shifted back and a repeated playback begins. Upon attaining the count condition ("O") the counter turns on a signal device providing a marking location signal. Upon a non-correspondence in time of the location signal with the sound event, the count condition of the counter, and thus the location signal, can be charged relative to the sound event, and the location signal is used for positioning the sound event with respect to a reference point on the device.
