Synchronization of Digital Audio Channels to Analog Soundtrack

Authors: Karamon, John J.

AES Convention 93 · Paper 3439 · October 1992

Abstract

The synchronizing system simplifies the process of providing digital sound to the cinema. This new technology achieves digital sound while maintaining the use of regular optical or magnetic soundtracks and the standard theater projector. The technology uses the analog and digital audio that are recorded from the same audio master, and thus have very similar audio structures. These structures are continuously compared by the system, and as a result, the digital audio can quickly be correlated and synchronized to the film's soundtrack. The technology is based on U.S. patent 4,839,733, -Method and System for Synchronization of an Auxilliary Sound Source to Motion Picture Film, Videotape or Other Picture Source Containing a Sound Track.-
