mixing

In motion picture production, "mixing" refers to the postproduction process of combining various recorded sound elements—dialogue, sound effects, and music—onto a single, synchronized soundtrack. Less than 25 percent of a film's sound is typically captured during initial photography; the rest is added and refined later.1

Sound mixers use specialized consoles to adjust the loudness and quality of individual tracks, ensuring a dramatic balance between dialogue, music, and effects. Modern techniques, including computerized consoles, allow for precise adjustments and corrections without needing to re-record entire segments. This process is crucial for creating the final auditory experience of a film.123
