Chapter 01 - What is a Sound Effect?
The following is a sample paragraph from The Sound Effects Bible.
Filmmaking is a very complicated process. It is a machine with dozens of integral parts that have to keep in sync, quite literally, with one another in order to create the well-balanced and perfectly aligned product of film. Take away or misalign any of the machine’s moving parts and the product suffers greatly. According to George Lucas (the guy who made a space movie, the name of which I can’t seem to remember), “sound is half of the experience.” Therefore, sound is half of the machine.
