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.

A chorus of many voices, and a scale model for the temple.


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.

A composition platform and prototype for further spatial audio installations, including Cathedral-64.
