01Executive Overview
A procedural 10-Point Dolby Atmos 7.1.4 3D Spatial Audio Engine written in raw mathematical DSP code and synced with real-time 2.5D SVG Vector Graphics. Zero DAW plugins. Zero pre-recorded audio assets. 100% procedural trigonometric synthesis.
02The Engineering Challenge
Operational Problem & Constraints
Critical friction and failure modes observed in existing workflows
Spatial audio production traditionally relies on proprietary, heavyweight DAW plugins and static binaural recordings that cannot dynamically adapt to interactive programmatic vector geometry in real time.
03Architecture & Technical Solution
System Architecture & Algorithmic Design
Engineering methodology, model selection, and pipeline design
Developed a ground-up mathematical acoustic engine implementing the Frontal Concha Acoustic Horn boost (+6.5 dB at 4.2 kHz), Rear Pinna Shadowing low-pass filters, Circular Shortest-Angle Gain Laws, Woodworth Spherical Head ITD equations, and 6-Boundary Shoebox early reflection matrices coupled with 2.5D screen coordinates.
04Quantified Impact & Benchmarks
Empirical Outcomes & Performance Metrics
Validated benchmarks, latency figures, and operational efficiency
Delivers true 360-degree out-of-head externalized auditory immersion and 2.5D ray-tracing at 48 kHz / 60 FPS in standard browser environments and uncompressed Master WAV exports.
