Creating sound effects by watching the picture and mimicking the action, often with props. Foley artists, also known as Foley walkers, make use of a variety of objects and/or surfaces to elicit realistic sound effects; most commonly used in the recording of on-screen footsteps, hence the term “walkers.” Foley effects are named after Hack Foley, who was the head of the sound effects department at Universal Studios. The audio track which contains Foley sounds is known either as a cloth track (west coast) or rustle (east coast.)
