Rubber-Band Mixing

he manual, keyframe-based technique of adjusting audio levels directly on the timeline, so-named for the visual representation of the volume line that can be pulled up or down like a rubber band. Described by Walter Murch as a 'largely intuitive' process, it allows for precise, moment-to-moment sculpting of the soundscape, particularly for ducking music under dialogue. This tactile method prioritizes the editor's 'feel' for the mix over automated processes, turning a technical task into an act of performance.
