The term computer-generated most often
refers to a sound or visual that has been created in whole or in
part with the aid of computer software. It can, but does
not customarily, refer to something produced solely by computer hardware, like a noise from a hard disk
drive or a printed page from a printer (although
the object printed on the paper may be computer-generated, the
physical page itself is not).
Sounds and visuals are the most easily computer-generated objects.
They are created either from the ground up, or by using real-world
models recorded by a microphone or camera, over which computer-generated objects
are placed.
