Foley Artist research

A foley artisit job is to create sound effects for film, tv or video games. They need to create sounds externally and add them into the final clip. The priority for filming in terms of audio is to record dialog rather than sound effects so they must be created and added in. They are usually difficult to recreate a what the sound effect is being used for so immitations are used. Also it can enhance the atmosphere of a clip by making it more dramatic to give more impact.
First footsteps of the characters are recorded then the background footsteps. Then they go through a prop pass which is creating sound effects for all the things happening on screen.

Foley artists need to be skilled and experienced in thinking of ways to make different sounds to full effect. A creative mind is needed to do this and an ear for how the effect will work with a clip. Timing is also important because they need to sync it to the footage.
A foley artist will use real objects to create sound effects rather than digital techniques is because they can create a more authentic sound and it is often possible to create many different sounds with the same item in the way it is manipulated.
