It is possible to think of the two extremes of the world of sound as the inner domain of microsound (less than 50 ms) where frequency and time are interdependent, and the external world of sonic complexity, namely the soundscape. In terms of sonic design, the computer is increasingly providing tools for dealing with each of these domains, such as granular synthesis and multi-channel soundscape composition. The models of interaction involved with the complexity of each of these domains are instructive, and will be presented with sound examples.
Barry Truax is a Professor in both the School of Communication and the School for the Contemporary Arts at Simon Fraser University where he teaches courses in acoustic communication and electroacoustic music. He has worked with the World Soundscape Project, editing its Handbook for Acoustic Ecology, and has published a book Acoustic Communication dealing with all aspects of sound and technology. As a composer, Truax is best known for his work with the PODX computer music system which he has used for tape solo works and those which combine tape with live performers or computer graphics. In 1991 his work, Riverrun, was awarded the Magisterium at the International Competition of Electroacoustic Music in Bourges, France, a category open only to electroacoustic composers of 20 or more years experience.
