Foley

he art of re-creating and recording sound effects in a studio to synchronize with the picture, often to enhance or replace original production audio. Common examples include footsteps, cloth movement, and object handling. In documentary, it can be used to bring life to silent archival footage, such as adding the sound of skateboard grinds to MOS Super 8mm film, as described by editor Paul Crowder for 'Dogtown and Z-Boys'.
