Sound-on-Disc

Sound-on-disc is a category of sound film techniques that use a phonograph or disc-based system for synchronising sound with a motion picture.

Sound-on-disc is an audio technology that was initially conceived during the early 20th century, achieving commercial feasibility in the late 1920s. This system involved the recording of music and dialogue onto wax records, which were subsequently played in synchronisation with the film using a turntable. This turntable was intricately linked to a film projector through a carefully coordinated mechanism, ensuring that sound and visuals harmoniously converged for a complete cinematic experience.
