What did the Vitaphone system do?

• A. It synchronized sound disks with film to provide audio for movies.
• B. It recorded actors' voices directly onto film
• C. It projected both audio and video on separate screens
• D. It allowed for widescreen formats

Answer: (A)

Vitaphone introduced a synchronized sound-on-disc system, where a phonograph record ran in sync with the film projector to provide the movie’s audio. The disk carried the soundtrack separately from the film, and the projector and turntable had to stay in perfect timing so the audio stayed aligned with the on-screen action. This enabled spoken dialogue and musical cues in early sound films, making talkies possible. It did not record voices directly onto the film, nor did it project audio on a separate screen or use widescreen formats.
