The Movietone sound system is a sound-on-film method of recording sound for motion pictures that guarantees synchronization between sound and picture. It achieves this by recording the sound as a variable-density optical track on the same strip of film that records the pictures. Although sound films today use variable-area tracks, any modern motion picture theater (excluding those that have transitioned to digital cinema) can play a Movietone film without modification to the projector. Movietone was one of four motion picture sound systems under development in the U.S. during the 1920s, the others being DeForest Phonofilm, Warner Brothers' Vitaphone, and RCA Photophone, though Phonofilm was primarily an early version of Movietone.

Famous quotes containing the words sound and/or system:
“An old pond—
a frog tumbles in—
the sound of water.”
—Matsuo Basho (1644–1694)
“Loving feels lonely in a violent world,
irrelevant to people burning like last year’s weed
with bellies distended, with fish throats agape
and flesh melting down to glue.
We can no longer shut out the screaming
That leaks through the ventilation system ...”
—Marge Piercy (b. 1936)
