I want to know how the professional codec 5.1 Dolby Digital Audio (Left, Right, Center, subwoofer, left-surround, right-surround) is used in movies?
The discussion about the codecs used in movies is very ample. For example, Dolby Digital sets a standard with its usage in movies, because movie producers and audio engineers use the codecs to deliver maximum audio quality while keeping the file size to a minimum. This enables them to embed audio in DVDs played at the cinema. The Dolby Digital is also used in games, home cinemas, etc. I recommend checking the official page where many other specifications are listed and explained as well. You have the possibility to compare the standards used in movies.
