Dickson as a test of the early version of the Edison Kinetophonecombining the Kinetoscope and phonograph. The idea of combining motion pictures with recorded sound is nearly as old as the concept of cinema itself.
On February 27,a couple of days after photographic pioneer Eadweard Muybridge gave a lecture not far from the laboratory of Thomas Edisonthe two inventors privately met. The two devices were brought together as the Kinetophone inbut individual, cabinet viewing of motion pictures was soon to be outmoded by successes in film projection.
These appear to be the first publicly exhibited films with projection of both image and recorded sound. The primary issue was synchronization: While motion picture projectors soon allowed film to be shown to large theater audiences, audio technology before the development of electric amplification could not project satisfactorily to fill large spaces.
Finally, there was the challenge of recording fidelity. The primitive systems of the era produced sound of very low quality unless the performers were stationed directly in front of the cumbersome recording devices acoustical horns, for the most partimposing severe limits on the sort of films that could be created with live-recorded sound.
Cinematic innovators attempted to cope with the fundamental synchronization problem in a variety of ways. An increasing number of motion picture systems relied on gramophone records —known as sound-on-disc technology; the records themselves were often referred to as "Berliner discs", after one of the primary inventors in the field, German-American Emile Berliner.
For some years, American inventor E. The phonograph was connected by an intricate arrangement of pulleys to the film projector, allowing—under ideal conditions—for synchronization. However, conditions were rarely ideal, and the new, improved Kinetophone was retired after little more than a year.
Inas part of the research he was conducting on the photophonethe German physicist Ernst Ruhmer recorded the fluctuations of the transmitting arc-light as varying shades of light and dark bands onto a continuous roll of photographic film.
He then determined that he could reverse the process and reproduce the recorded sound from this photographic strip by shining a bright light through the running filmstrip, with the resulting varying light illuminating a selenium cell. He called this invention the photographophone which he summarized as: InLauste was awarded the first patent for sound-on-film technology, involving the transformation of sound into light waves that are photographically recorded direct onto celluloid.
As described by historian Scott Eyman, It was a double system, that is, the sound was on a different piece of film from the picture In essence, the sound was captured by a microphone and translated into light waves via a light valve, a thin ribbon of sensitive metal over a tiny slit.
The sound reaching this ribbon would be converted into light by the shivering of the diaphragm, focusing the resulting light waves through the slit, where it would be photographed on the side of the film, on a strip about a tenth of an inch wide. InFinnish inventor Eric Tigerstedt was granted German patentfor his sound-on-film work; that same year, he apparently demonstrated a film made with the process to an audience of scientists in Berlin.
Two involved contrasting approaches to synchronized sound reproduction, or playback: Advanced sound-on-film[ edit ] InAmerican inventor Lee De Forest was awarded several patents that would lead to the first optical sound -on-film technology with commercial application.
If proper synchronization of sound and picture was achieved in recording, it could be absolutely counted on in playback. Over the next four years, he improved his system with the help of equipment and patents licensed from another American inventor in the field, Theodore Case. On June 9,he gave the first reported U.
