The Sound Era


Experimentation with sound film technology, both for recording and playback, was virtually constant throughout the silent era, but the twin problems of accurate synchronization and sufficient amplification had been difficult to overcome (Eyman, 1997). In 1926, Hollywood studio Warner Bros. introduced the "Vitaphone" system, producing short films of live entertainment acts and public figures and adding recorded sound effects and orchestral scores to some of its major features.

The real turning point came in late 1927, when Warners released The Jazz Singer, which was mostly silent but contained the first synchronized dialogue (and singing) in a feature film. It was a gargantuan success, as were follow-ups like Warners' The Lights of New York (1928), the first all-synchronized-sound feature. The early sound-on-disc processes such as Vitaphone were soon superseded by sound-on-film methods like Fox Movietone, DeForest Phonofilm, and RCA Photophone. The trend convinced the reluctant industry that "talking pictures", or "talkies," were the future.
