As 3D CGI animation is to film and game visuals, procedural audio is the synthesis of sonic material, usually at the point of delivery, based on the behaviour and interaction of sounding object models. It offers enormous advantages for space efficiency and control, providing rich interactive experiences unavailable from sample based methods. Many see it as the future of game audio. Pioneering researcher and author of the textbook Designing Sound, Andy Farnell presents some examples and commentary on the subject.
