High-Order Ambisonic Spatialization Suite with Dynamic DBAP Panning (Revision 3.2)
Discipline: Generative Software · Lead Researcher: Soren Lindqvist
OPERATIONAL ABSTRACT
A modular software library for positioning and animating multi-source audio in irregular 3D architectural spaces with up to 64 independent speaker outputs. Enhanced revision 3 with improved low-noise shielding and updated real-time firmware.
TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS
Combines Distance-Based Amplitude Panning (DBAP) with 5th-order spherical harmonic encoding, compensating for non-spherical loudspeaker placements via delay calibration. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
