Strategies in Diffuse Spatialization

This dissertation deals with strategies in spatialization of music. It tries to explore a certain concept of spatialization (Diffuse Spatialization) based on sounds as volumetric objects that have extension and occupy a space. Three different approaches are described: SupaStrings- a network of physical modelled strings with extent (multiple outputs per string) placed in a virtual sound stage. Parameter Field Synthesis- A grid of stationary sources, all using the same synthesis process, is driven by time-evolving scalar fields. Sine Fields- Sine wave generators are free to roam through a frequency scalar field; the frequencies are inherently connected to the locations in space. The three approaches were conceptualized and implemented using the SuperCollider audio synthesis programming language. Through the use of the different systems, namely in several live music performances, it was concluded that diffuse spatialization is a viable approach to spatialization, and one which still has potential for further developments
