Foley is the reproduction of everyday sound effects which are added in post production to enhance the quality of audio in movies, television and other media. The reproduced sounds can be anything from the swishing of clothing and footsteps to squeaky doors and breaking glass. The best foley art is so well integrated into a film that it goes unnoticed by the audience. It helps to create a sense of reality within a scene. Without these crucial background noises, movies feel unnaturally quiet and uncomfortable.
This is a pretty funny video that turns foley a bit on it’s head. Just watch.
