Hearing from within a sound: A series of techniques for deconstructing and spatialising timbre

Document Thumbnail

We present a series of compositional techniques for deconstructing and spatialsing timbre in an immersive audio environment. These techniques aim to engulf a spectator within a given abstract timbre, by highlighting said timbre’s distinct spectral and gestural characteristics through our approach to sound spatialisation. We have designed these techniques using both additive synthesis, and time-frequency analysis and resynthesis, building upon analytical methods such as the discrete Fourier transform and the joint time-frequency scattering transform. These spatialisation techniques can be used to deconstruct a sound into subsets of spectral and gestural information, which can then be independently positioned in unique locations within an immersive audio environment. We here survey and evaluate how perceptibly cohesive and aesthetically nuanced a timbre remains after deconstruction and spatialisation, when applied in both live performance and studio production contexts. In accordance with their varying design, each spatialisation technique engenders a unique aesthetic experience, affording a listener various means through which to hear from within a sound.
