Spatial effects induced by a sound centrifuge

Abstract : If revolutions of sound in space go beyond a certain barrier of revolutions per second, they become something else” explained Karlheinz Stockhausen during a conversation with Jonathan Cott in 1971. This observation gave birth to a series of controlled scientific experiments we have conducted at CIRMMT since 2008. We first estimated perceptual thresholds for auditory motion and velocity perception and later investigated the influence of reverberation, spatialization techniques and loudspeaker configurations. Throughout this process, new tools based on a hybrid spatialization method combining numerical propagation and angle-based amplitude panning, were developed to move sounds around the listener at very high velocities. The revolution frequency can be in the same order of magnitude as audible frequencies. In this demonstration, spatial audio effects will be presented parametrically as core elements of spatial studies based on velocity
