RECOMBINANT SPATIALIZATION FOR ECOACOUSTIC IMMERSIVE ENVIRONMENTS
Matthew Burtner, David Topper · 2004
An approach to digital audio synthesis is implemented using recombinant spatialization for signal processing. This technique, which we call Spatio-Operational Spectral Synthesis (SOS), relies on recent theories of auditory perception, especially research by Kubovy and Bregman. In SOS, the perceptual spatial phenomenon of objecthood is explored as an expressive musical tool. In musical applications of these theories, we observe the emergence of a "persistence of audition " exposing interesting opportunities for compositional development. In essence, SOS, breaks an audio signal into salient components then recombines and spatializes them in a multichannel environment. Following an introduction to the technique and several examples demonstrating potential applications, this paper concentrates on some applications of the technique in ecoacoustic compositions by Matthew Burtner, Anugi Unipkaaq, Sikniq Unipkaaq and Siku Unipaaq. These works draw on environmental systems as models for multichannel processing. 1.
