Sound
Foley
The reproduction of everyday sound effects that are added to films in post-production.
In Depth
Named after Jack Foley, this process involves artists watching the film and physically making sounds (footsteps, cloth movement, breaking glass) in sync with the picture to replace or enhance the on-set audio.
Example
"The sound of crunchy footsteps on snow in 'Frozen' was actually a Foley artist squeezing bags of cornstarch."
