Multichannel Sound for Film, Video, and Home Music Applications
Presentation in the theater is normally via four channels: three behind the screen and a surround channel. New digital formats allow for five channels, three behind the screen and two for surround.
Control of the playback acoustical environment. Unlike the wide variety of consumer playback environments (automobile, home, or headphones), motion pictures are primarily shown in environments that are not unlike those where the product was mixed.
Extensive postproduction activity. Music, dialog, and effects are all separately recorded and premixed and are brought together during a final mixdown operation after the film has been edited.
