Sound film

Sound film, also known as "talkie," is a type of motion picture that synchronizes audio with the visual images, allowing audiences to hear dialogue, music, and sound effects as they watch. Before sound films, movies were silent and often accompanied by live music. The introduction of sound films in the late 1920s revolutionized filmmaking by creating a more immersive and realistic experience. The technology involves recording sound separately or simultaneously with filming and then synchronizing the audio with the visuals during playback. This innovation significantly enhanced storytelling, actor performance, and audience engagement.
