CHOIR-64
- 2020 - 33” W x 33“ H x 7” D

A psychoacoustic instrument and composition system, consisting of 64 individually addressable 1-bit (square wave) audio channels arranged in an 8x8 speaker grid, designed for experiments with spatialization and phase relationship effects.

Swarming tones shift and modulate over time, dancing across the surface of the altar. A wafting sound that hangs heavily in the air like incense.


The first musical composition written for this system, ‘Spatial Etude No.1’, consists of a long form generative drone piece in which elements are slowly changed over time. Each voice consists of an individual tone which moves between the speakers of the array, creating different chords and spatial effects as elements generatively spawn, decay, and modulate in path and frequency.

Please note: Due to the spatial acoustic nature of this piece, meaningful recording of the audio output is difficult. In order to experience the full spatial effect of sound moving across the array of speakers it is necessary to be present with the instrument.
