Wave Field Synthesis Composition
“When The Sound of Your Voice Resonates Like Time” is a composition that explores the relationship between rhythmic perception, spatial perception, and the perception of pitch. Pitch can be seen as a recurring vibration above 16 to 20hz – anything below this can be described as individual pulses, or rhythm. Imagine a pitch located at a single location, pulsating at hundreds of times a second. But then imagine this pitch dissolving – with each subsequent pulse traveling to a different location in the room – spreading a unified pitch into a swarm of disparate pulses. At what point of spatial diffusion does a pitch cease to be a pitch? At what proximity do rhythm pulses morph into a pitch? By dissolving one pitch through space, a whole multitude of pitches and rhythms is possible, allowing for complex compositions generated from a single pitch, simply through the process of spatialization.
“When The Sound of Your Voice Resonates Like Time” was commissioned by the I²Audiolab HAW Hamburg University for their Wave Field Synthesis sound system and awarded first prize in their Raum:Klang Competition.
Technical examples using pure impulse waveforms – alternating between stereo panning and mono, resulting in a one octave jump:
EXAMPLE: six sources at 10hz would allow for four different constant pitches/rhythms – 10hz, 20hz, 30hz, 60hz. Visualized as such:
