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.
- See the 35 mm film article for more information on both digital and analog methods.

Famous quotes containing the word sound:
“Today we seek a moral basis for peace.... It cannot be a lasting peace if the fruit of it is oppression, or starvation, cruelty, or human life dominated by armed camps. It cannot be a sound peace if small nations must live in fear of powerful neighbors. It cannot be a moral peace if freedom from invasion is sold for tribute.”
—Franklin D. Roosevelt (1882–1945)
“The last sound on the worthless earth will be two human beings trying to launch a homemade spaceship and already quarreling about where they are going next.”
—William Faulkner (1897–1962)
“Is there no hope for me? Is there no way
That I may sight and check that speeding bark
Which out of sight and sound is passing, passing?”
—Paul Laurence Dunbar (1872–1906)
