Foley is a sound design technique used in film, television, and theater to create and enhance audio effects. It involves recording everyday sounds in a studio to match the actions on screen, such as footsteps, rustling clothes, or the clinking of objects. This process helps to make the audio experience more immersive and realistic for the audience. The term comes from Jack Foley, a pioneer in the field who developed these techniques in the early 20th century. Foley artists use various props and tools to replicate sounds, ensuring that the audio complements the visual elements and enhances storytelling.
