Foley is the art of creating and adding realistic sound effects to films, videos, and other media in post-production to enhance audio quality. Foley artists use a variety of props and recording equipment to reproduce everyday sounds, such as footsteps, clothing movements, and object interactions, which are synchronized to the visual elements of the film. This process allows for complete control over the quality and characteristics of the sounds, adding depth and realism to the audio. Foley complements or replaces sound recorded on set during filming and is essential for creating a consistent and coherent auditory experience for the audience.
