A DAW allows sounds, stored as computer files on a host computer, to be placed in timed synchronization with a motion picture, mixed, manipulated, and documented. The standard DAW system in use by the American film industry, as of 2012, is Avid's Pro Tools, with the majority running on Macs. Another system in use presently is Yamaha owned Steinberg's cross platform DAW Nuendo running on Macs using operating system Mac OS X but also on Windows XP.
