Foley is the art of recreating realistic sounds in film. Foley artists recreate everyday sounds like footsteps or gunshots that were not captured well during filming. This allows them to enhance audio quality and add missing sounds during post-production. Some methods include using shoes on a floor to mimic footsteps or speeding up recordings of grapes to sound like gunshots. Foley is useful for improving low quality audio, creating sounds from unexpected objects, and reusing recorded effects between projects. The technique originated from live radio broadcasts and got its name from Jack Donovan Foley, who synchronized off-screen sound effects for a 1914 film.
