Keynote 2. Accessibility and web audio technologies
summary
Demonstrates a working virtual binaural bus built with the Resonance-style 3D audio approach, navigable by keyboard so blind users can move and localize sources; runs in Firefox but Chrome needs manual AudioContext resume and some users hear only collisions. Shows a WebAssembly audio SDK (Superpowered WebAssembly) for pitch-preserving rate changes and a prototype cross-platform time-stretching audiobook player. Runs a listener quiz: only 1 of 14 correctly counted occupants, 11/16 identified road side, ~10/16 located the engine—proofs of concept that mostly work but need polish and standards.
