Foley Sounds vs Real Sounds

This paper is an initial attempt to study the world of sound effects for motion pictures, also known as Foley sounds. Throughout several audio and audio-video tests we have compared both Foley and real sounds originated by an identical action. The main purpose was to evaluate if sound effects are always better than real sounds [1]. Once this aspect is cleared up, the next step will be to understand how Foley effects exaggerate important acoustic features. These are the basis for being able to create a database of expressive sounds, such as audio caricatures, that will be used in different applications of sound design such as advertisement or soundtracks for movies.
