Introduction to Digital Audio
An Overview
Sound In Media
 Sound Design gives meaning to noise, music and dialog
 A good design makes the listener immerse into the story, characters,
emotions, environment and genre
 It’s the intrinsic element of storytelling
 It’s the function of combining sight and sound to enrapture audiences
Artistic elements
 Just like doing a painting or taking a picture, audio needs depth,
composition, contrast and an aural stage
 There should be a sense of location, an intensity of emotions and
movement of time
 Creativity is important in creating a sound design
 The audio design should be able to tell the story on its own, independent
of the visuals
