ABSTRACT
Historically, media production is the process of copying images or sound from one place onto another. Pieces of movie film are copied onto others for special effects, composite masters, and release prints. Digital audio handles data loss differently: • Small data errors are reconstructed perfectly. The system uses checking digits to find out what the missing data should have been, and recreates it. Digital circuits are immune to gradual noise because they ignore ambiguity. A bit of information is either zero or one. If a signal falls between those two values, the circuit Producing Great Sound for Film and Video picks a value and ignores the difference. Computer designers combine bits together to represent high numbers. Each time they add another bit, they double the number of possibilities. Doubling the possibilities, each time add a bit, makes a big difference.
