Abstract: The editing of video signals is usually based on the visual content of the video signal. This means the associated audio signal editing must be done to match the required final visual product. Since the visual editing is restricted at least to integer fields and more generally to every other frame, these same time restrictions will apply to the audio editing. When the video and audio signals are digitally encoded, their sampling rates should be related to each other exactly. This article shows how video systems may use the 50 kHz audio sample rate, how this rate is locked to the video system, and methods of performing the actual digital audio edits to coincide acceptably with the associated edited digital video signal.
