Sound
Regardless of the sound format, any sound represented on the film image itself will not be the sound for the particular frame it occupies. In the gate of the projector head, there is no space for a reader, and the film is not travelling smoothly at the gate position. Consequently, all optical sound formats must be offset from the image because the sound reader is usually located above (for magnetic readers) or below (for optical readers) the projector head.

Famous quotes containing the word sound:
“Envy awakens at the sound of a distant laugh.”

“One dreadful sound could the Rover hear,
A sound as if, with the Inchcape Bell,
The Devil below was ringing his knell.”
—Robert Southey (1774–1843)
“There have been many stories told about the bottom, or rather no bottom, of this pond, which certainly had no foundation for themselves. It is remarkable how long men will believe in the bottomlessness of a pond without taking the trouble to sound it.”
