An artistic approach is taken that uses principles in quantum mechanics to understand the signature sound created by granular synthesis in an undergraduate course on music synthesis techniques

Abstract

Music Synthesis Techniques is an advanced undergraduate course that explores how various methods are used to create and manipulate synthesized sounds used in sound design and audio production. Students explore their understanding through the creation of a series of short, one-minute compositions that utilize each technique. This paper focuses on that of granular synthesis. Granular synthesis is a music synthesis technique that is used to create unique and alluring sounds that has captivated modern music listeners. For audio engineers and sound designers, the term granular synthesis has always held an aura of mystery surrounding it. Recent developments in plug-ins for digital audio workstations allow them to easily create its signature sound, which have created a way to use granular synthesis as an art form. Unlike other methods, granular synthesis is rooted in the laws of quantum mechanics. The Heisenberg Uncertainty Principle is explored to understand how granular synthesis creates its signature sound, which in turn is then used to create artistic compositions through the manipulation of the variables. Several examples from student work as well as collaborative work will be included.
