PROT-005prototypeVERIFIED RECORD

Analog Wave-Terrain Synthesizer with Precision Optical XY Tracking

PROT-005: WAVE-TERRAINCLEARANCE: BLACK-BOXSTATUS: CONTAINED HAZARDYEAR: 2025

Discipline: Experimental Audio Systems · Lead Researcher: Mireille O’Connor

OPERATIONAL ABSTRACT

A physical modeling synthesizer that maps hand gestures across a three-dimensional topographic relief surface into complex cyclic audio waveforms.

TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS

Dual infrared laser sensors track position coordinates over carved wooden or cast bronze terrain surfaces, reading elevation contours as real-time wavetable indices at audio rate. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
