Which technology allowed sound to be synchronized with the film for Warner Brothers' productions?

• A. Vitaphone
• B. Technicolor
• C. Dolby
• D. THX

Answer: (A)

The idea being tested is how early movies achieved synchronized sound with the moving images, specifically for Warner Bros. in the transition from silent to talking pictures. The technology responsible was a sound-on-disc system called Vitaphone. In this setup, the audio track was recorded on a separate vinyl disc that ran in lockstep with the film projector. The projector and the disc motor were mechanically linked, so as the film played, the disc played the audio in precise synchronization, allowing dialogue, music, and effects to match the action on screen. This made Warner Bros.’ early talkies, such as The Jazz Singer, possible and marked a pivotal shift in cinema. Technicolor is the process for adding color to films, not synchronized sound. Dolby refers to later sound technologies, including noise reduction and multi-channel sound, developed long after the silent-to-sound transition. THX is a modern cinema sound standard and certification. None of these provided the synchronous sound-on-disc method that Warner Bros. used with Vitaphone.
