Abstract: Today's state-of-the-art criteria for motion-picture sound reproduction may fall far short of meeting the demands of motion-picture audiences in five to ten years. Present-day A-chain capabilities far exceed the capabilities of motion-picture theater playback equipment, and the gap widens at an ever-increasing rate. The authors propose a quantum improvement in film-sound playback systems as a necessary means to gain significant improvements in sound quality in the motion-picture theater.
