Foley is the reproduction of everyday sound effects that are added to film,video, and other media in post-production to enhance audio quality.They include sounds such as footsteps, crockery clinking, paper folding, clothes rustling,doors opening and slamming, glass breaking, punches hitting, etc. etc. In other words, many of the sounds that the sound recordists on set did their best to avoid recording during the shoot.
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.For example, an introductory shot of a biker wearing a leather jacket might be enhanced if we hear his jacket creak as he enters the shot – but do we really want to hear it every time he moves? By adding the foley sound fx in post, we can control its intensity, and fade it down once the dialogue begins.
Foley is usually performed by Foley artists.Jack Donovan Foley was the developer of many sound effect techniques used in filmmaking. He is credited with developing a unique method for performing sound effects live and in synchrony with the picture during a film’s post-production. Accordingly, individuals engaged in this trade are called “Foley artists”.
The Foley artists can clearly see a screen which displays the footage they are to add sound fx to, and they perform their sound effects while watching this screen for timing. The actions they perform can include walking, running, jostling each other, rubbing their clothing, handling props, and breaking objects, all while closely observing the screen to ensure their sound fx are appropriate to the vision.
