How do Foley artists make the sounds you hear in films?

Foley artists recreate the physical sounds of a film or television show in a studio, performing them in time with the picture. They use props, shoes, cloth and surfaces, and the results are layered onto the soundtrack. The sounds replace or supplement field recordings taken at the time of filming. Often they are not literal copies of the original sound; creative materials and movements can give a sharper, more precise result. [1]

The US Bureau of Labor Statistics explains that microphones on a set or location are designed to capture dialogue, so other sounds can seem quiet or get lost. Foley artists therefore create almost all of these sounds later in a studio, away from the film set. A sound effects editor may instead bring in library effects, but a Foley artist interviewed by the Royal Television Society says recording sounds as they happen on screen captures detail, such as whether a glass is put down with care or with anger. The sound mixer then decides whether a Foley effect is needed or whether to keep the location sound. [2] [3]

Artists first watch the whole video and take notes, then gather props and break each scene into individual sounds. Work is done on a Foley stage, an acoustically controlled studio filled with props, surfaces and materials. Cue sheets specify the timing of movements; for someone getting into a car, one might list the footsteps, the door handle, clothing rustle, keys and the ignition. The artists rehearse against the picture, then record in real time while rewatching the film, typically with sensitive condenser microphones. Sound designers tweak the reels, mixers add them to the dialogue and effects tracks, and the director approves them or asks for retakes. [1] [2]

Work is often divided between two artists, each taking certain characters, with each character on a separate track recorded in 15-minute reels. [2]

Backstage describes three main categories: feet, movement and specifics. Footsteps use many shoes on many floors. Movement covers subtle sounds such as clothing brushing past. Specifics cover everything else, such as a banging door. Foley artist Marko Costanzo told CineMontage that footsteps can take half a day, followed by body movements and actions like opening doors and setting down plates. Performers also act the part: a calm person's steps are light and steady, an angry person's stomp, and artists may wear ballet shoes or combat boots to suit the character. Because the microphone stays in one spot, artists walk in place, and the Foley mixer moves the sound around in space. [1] [4] [2] [5]

Standard substitutes include shaking latex gloves or an umbrella for wings, pressing cornstarch for snow, snapping celery for breaking bones, and frying bacon for rain. Another artist, Joanna Fang, describes pasta shells sounding like breaking bones. Time depends on budget, according to Costanzo: two to five days for low-budget films, one to two days for a typical television episode, almost two weeks for medium budgets and three to five weeks for big ones. A British Foley artist reports about three days for an hour of drama. [1] [6] [3]
