Steps from silent to sound movies ,[object Object],[object Object],Three major problems of early sound movies: Synchronization – The pictures and sound were recorded and played back by separate devices, which were difficult to start and maintain in synchronization. Playback volume – 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 to satisfactorily fill large spaces. 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, imposing severe limits on the sort of films that could be created with l live-recorded sound.

Cinematic innovators attempted to cope with the fundamental synchronization problem; an increasing number of motion picture systems relied on gramophone records Innovations continued on other fronts. In 1907, Eugene Lauste 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. In 1913, Edison introduced a new cylinder, as the Kinetophone; instead of films being shown to individual viewers in the Kinetoscope cabinet, they were now projected onto a screen.
