External AV-sync errors can occur if a microphone is placed far away from the sound source, the audio will be out of sync because the speed of sound is much lower than the speed of light. If the sound source is 340 meters from the microphone, then the sound arrives approximately 1 second later than the light. The AV-sync delay increases with ...
The audio synchronizer receives the DDO signal and in response delays the audio by an equivalent amount, thereby maintaining proper audio-video sync. Modern audio synchronizers operate by digitizing and writing the audio signal into a ring memory, which is most commonly a RAM -based memory having independent read and write ability.

The horizontal sync signal is a single short pulse that indicates the start of every line. The rest of the scan line follows, with the signal ranging from 0.3 V (black) to 1 V (white), until the next horizontal or vertical synchronization pulse. The format of the horizontal sync pulse varies.
A cable conducts the sync pulse from camera to sound recorder. The sync pulse is typically a sine wave of 50 or 60 Hz with an RMS amplitude of approximately 1 volt. [4] This double-system audio recording could then be transferred or "resolved" to sprocketed magnetic film, with sprocket holes that match one to one with the original camera film.
