Abstract
Apparatus for identifying edit points in a digital audio signal recorded on a record medium in association with a video signal and a time code signal, comprises a random access memory (3) for storing a reproduced segment of the digital audio signal and the associated time code signal, a monitor (2) for displaying the image corresponding to a reproduced portion of the associated video signal, a digital-to-analog converter for converting that part of the segment of the digital audio signal corresponding to the displayed image and read from the random access memory (3) by reference to the stored time code for reproduction by a loudspeaker (4), a video screen (6) for displaying the waveform of the analog-converted audio signal with a cursor (8) which relates the waveform to the image displayed on the monitor (2), and a register (7) for recording the time code read from the random access memory (3) and corresponding to a required audio edit point at which the cursor is positioned.
