Click through each page of this article to view and hear video clips from landmark films released with Dolby sound formats. Headphones required! While the British thriller "Callan" starring Edward Woodward was the first film to feature release prints with a Dolby-encoded optical soundtrack, Ken Russell's "Lisztomania," a psychedelic interpretation of the life of Frank Liszt starring The Who's Roger Daltry, was the first Dolby release in stereo. Dolby Stereo was a deceptively simple concept: with two optical soundtracks on the film strip, additional audio information was encoded as out-of-phase signals.
A decoder on the projector would then separate the out-of-phase sound which would translate as additional channels, producing four channels of sound to be spread across the cinema. What this clip from "Lisztomania" which features a Frankenstein monster-like incarnation of Richard Wagner, a slaughter of Jews, and Nazi girls with voodoo dolls -- hey, it's a Ken Russell film!

Because there was little spatial differentiation in dialogue between, say, left and center, the mixers for "Star Wars" kept the L-C-R tracks, but used the remaining two front tracks for isolated, low-frequency effects LFE, a. Originally Dolby Sound was incompatible with mono projectors, so "Star Wars" was released in three different sound mixes: 70mm six-track magnetic stereo, 35mm Dolby stereo optical, and 35mm optical mono, with slight editorial differences among them.
The soundtrack, boasting not just vivid sound effects but also John Williams' music, became as much a star of the film as the visual effects. The success of "Star Wars" and "Close Encounters of the Third Kind" not only inspired more film producers to use Dolby Stereo, but also spurred more and more theater owners to shell out for upgrades to their sound systems.
While there were fewer than 50 theaters in the U. The sound mixers of "Superman," which received a very wide 70mm release, experimented with the film's surround tracks, splitting them to incorporate left and right information. A third company entered the surround-sound fray in This 6. I would like to receive exclusive offers and hear about products from InformIT and its family of brands.
