Foley techniques are sound effects created in post-production to enhance audio in films, television shows, and video games. Named after sound effects artist Jack Foley, these techniques involve recording everyday sounds, like footsteps or rustling clothes, to match the on-screen action. This adds realism and depth to the audio experience. Foley artists use various props and tools to replicate sounds, often in a studio setting. For example, they might walk on different surfaces to create the sound of footsteps or use a microphone to capture the sound of a door creaking. This meticulous process helps immerse the audience in the story.
