ABSTRACT:
Apparatus for monitoring reproduced audio signals during fast playback operation comprises a bucket-brigade device for storing pieces of audio information reproduced from a recording medium at a high speed. The stored pieces of information are read out in a sequence at a slower speed than they were stored when the magnitude of the reproduced audio signal exceeds a predetermined value so that the audio information will be restored to the original pitch to be monitored. The interval for which an audio signal is stored in the bucket-brigade device may be controlled in accordance with the speed of the recording medium.
