Vitaphone was a sound film system used for feature films and nearly 1,000 short films made by Warner Bros. Pictures and its sister studio First National from 1926 to 1931. Vitaphone is the last major analog sound-on-disc system and the only one that was widely used and commercially successful. The soundtrack is not printed on the film, but issued separately on phonograph records. The discs, recorded at rpm (a speed first used for this system) and typically in diameter, are played on a turntable physically coupled to the projector motor while the film is projected. Its frequency response is 4300 Hz. Many early talkies, such as The Jazz Singer (1927), used the Vitaphone system. The name "Vitaphone" derived from the Latin and Greek words, respectively, for "living" and "sound".
The "Vitaphone" trademark was later associated with cartoons and other short subjects that had optical soundtracks and did not use discs.
Early history
In the early 1920s, Western Electric was developing both sound-on-film and sound-on-disc systems, aided by the purchase of Lee De Forest's Audion amplifier tube in 1913, consequent advances in public address systems, and the first practical condenser microphone, which Western Electric engineer E.C. Wente had created in 1916 and greatly improved in 1922. De Forest debuted his own Phonofilm sound-on-film system in New York City on April 15, 1923, but due to the relatively poor sound quality of Phonofilm and the impressive state-of-the-art sound heard in Western Electric's private demonstrations, the Warner Brothers decided to go forward with the industrial giant and the more familiar disc technology.
The business was established at Western Electric's Bell Laboratories in New York City and acquired by Warner Bros. in April 1925.Sperling, Millner, and Warner (1998), p. 111. Warner Bros. introduced Vitaphone on August 5, 1926, with the premiere of their silent feature Don Juan, which had been retrofitted with a symphonic musical score and sound effects. There was no spoken dialog. The feature was preceded by a program of short subjects with live-recorded sound, nearly all featuring classical instrumentalists and opera stars. The only "pop music" artist was guitarist Roy Smeck and the only actual "talkie" was the short film that opened the program, Introduction of Vitaphone Sound Pictures, four minutes of introductory remarks by motion picture industry spokesman Will Hays.
Don Juan was able to draw huge sums of money at the box office, but was not able to recoup the expenses Warner Bros. put into the film's production.Sperling, Millner, and Warner (1998), p. 113. After its financial failure, Paramount head Adolph Zukor offered Sam Warner a deal as an executive producer for Paramount if he brought Vitaphone with him.Sperling, Millner, and Warner (1998), p. 114. Sam, not wanting to take any more of Harry Warner's refusal to move forward with using sound in future Warner films, agreed to accept Zukor's offer, but the deal died after Paramount lost money in the wake of Rudolph Valentino's death. Harry eventually agreed to accept Sam's demands.Sperling, Millner, and Warner (1998), p. 116. Sam then pushed ahead with a new Vitaphone feature starring Al Jolson, the Broadway dynamo who had already scored a big hit with early Vitaphone audiences in A Plantation Act, a musical short released on October 7, 1926. On October 6, 1927, The Jazz Singer premiered at the Warner Theater in New York City, broke box-office records, established Warner Bros. as a major player in Hollywood, and is traditionally credited with single-handedly launching the talkie revolution.
At first, the production of Vitaphone shorts and the recording of orchestral scores were strictly a New York phenomenon, taking advantage of the bountiful supply of stage and concert hall talent there, but the Warners soon migrated some of this activity to their more spacious facilities on the West Coast. Dance band leader Henry Halstead is given credit for starring in the first Vitaphone short subject filmed in Hollywood instead of New York. Carnival Night in Paris (1927) featured the Henry Halstead Orchestra and a cast of hundreds of costumed dancers in a Carnival atmosphere.
Process
From the perspective of the cast and crew on the sound stage, there was little difference between filming with Vitaphone and a sound-on-film system. In the early years of sound, the noisy cameras and their operators were enclosed in soundproofed booths with small windows made of thick glass. Cables suspended the microphones in fixed positions just above camera range, and sometimes they were hidden behind objects in the scene. The recording machines were usually located in a separate building to completely isolate them from sound stage floor vibrations and other undesirable influences. The audio signal was sent from an on-stage monitoring and control booth to the recording room over a heavy shielded cable. Synchronization was maintained by driving all the cameras and recorders with synchronous electric motors powered from a common source. When music and sound effects were being recorded to accompany existing film footage, the film was projected so that the conductor could synchronize the music with the visual cues and it was the projector, rather than a camera, that was electrically interlocked with the recording machine.
Except for the unusual disc size and speed, the physical record-making process was the same one employed by contemporary record companies to make smaller discs for home use. The recording lathe cut an audio-signal-modulated spiral groove into the polished surface of a thick round slab of wax-like material rotating on a turntable. The wax was much too soft to be played in the usual way, but a specially supported and guided pickup could be used to play it back immediately in order to detect any sound problems that might have gone unnoticed during the filming. If problems were found, the scene could then be re-shot while everything was still in place, minimizing additional expense. Even the lightest playback caused some damage to the wax master, so it was customary to employ two recorders and simultaneously record two waxes, one to play and the other to be sent for processing if that "take" of the scene was approved. At the processing plant, the surface of the wax was rendered electrically conductive and electroplated to produce a metal mold or "stamper" with a ridge instead of a groove, and this was used to press hard shellac discs from molten "biscuits" of the raw material.
Because of the universal desirability of an immediate playback capability, even studios using sound-on-film systems employed a wax disc "playback machine" in tandem with their film recorders, as it was impossible to play an optical recording until it had made the round trip to the film processing laboratory.
A Vitaphone-equipped theater had normal projectors which had been furnished with special phonograph turntables and pickups; a fader; an amplifier; and a loudspeaker system. The projectors operated just as motorized silent projectors did, but at a fixed speed of 24 frames per second and mechanically interlocked with the attached turntables. When each projector was threaded, the projectionist would align a start mark on the film with the film gate, then cue up the corresponding soundtrack disc on the turntable, being careful to place the phonograph needle at a point indicated by an arrow scribed on the record's surface. When the projector was started, it rotated the linked turntable and (in theory) automatically kept the record "in sync" (correctly synchronized) with the projected image.
The Vitaphone process made several improvements over previous systems: Amplification – The Vitaphone system used electronic amplification based on Lee De Forest's Audion tube. This allowed the sound to be played to a large audience at a comfortable volume. Vitaphone was far from the first sound film system to use this technology, but it had amplifiers and loudspeakers, developed by Western Electric, which were state-of-the-art. Their performance was greatly superior to anything else of the kind then available, including the equipment used by De Forest to present his own Phonofilm sound-on-film exhibitions. Fidelity – Contrary to conventional wisdom, neither Vitaphone's ability to fill a theater with an adequate volume of sound nor its success in maintaining synchronization was unprecedented. Léon Gaumont's sound-on-disc films, which were being shown twenty years earlier, were successfully synchronized by the use of electrically interlinked multi-pole synchronous motors, and a pneumatic amplification system more than sufficed to fill Gaumont's 3,400-seat flagship theater in Paris with the recorded sound. That sound, however, had to be recorded by the same insensitive non-electronic method introduced by Thomas Edison in 1877, or alternatively by a very crude microphone-based variant which had logistical advantages but did not offer improved fidelity. The resulting sound, however greatly amplified it might be, was tinny and unclear and speech was difficult to understand. The footsteps and other incidental sounds that audiences instinctively expected to hear were missing. It did not sound "natural".
The Vitaphone system derived from extensive work on electronically recording and reproducing sound that had been carried out at Western Electric during the first half of the 1920s. Western Electric's engineers had developed a highly sensitive full-frequency-range condenser microphone, capable of capturing a whisper from several feet away, along with the electronic and mechanical equipment necessary to adequately record the audio signal it produced. As a result, the quality of Vitaphone sound in the theater came as a revelation to the audience at its public debut in 1926. It easily and dramatically surpassed anything previously achieved. It even surpassed the sound quality of Western Electric's own sound-on-film system, developed concurrently with the sound-on-disc system but still in the laboratory at that time, because at first the discs yielded better fidelity than an optical sound track.
These innovations notwithstanding, the Vitaphone process lost the early format war with sound-on-film processes for many reasons: Distribution – Vitaphone records had to be distributed along with film prints, and shipping the records required a whole infrastructure apart from the already-existing film distribution system. The records would start to suffer from audible wear after an estimated 20 playings (a check box system on the label was used to keep count) and were then supposed to be replaced with a fresh set. Damage and breakage were inherent dangers, so a spare set of discs was usually kept on hand, further adding to the costs.
