Presentation of an application that demonstrates object-based 3D audio rendering in the web browser using the Web Audio API. The application loads audio files containing object-based meta-data and provides head-tracked dynamic binaural rendering of the content to create an immersive 3D audio experience for headphone listeners. The user can interact with the rendering by muting individual audio objects and switching between the binaural rendering mode and conventional stereo rendering. The demo also includes visualisations of the object-based meta-data. Active objects are highlights on a 2D timeline visualisation and THREE.js is used to show the rendering location of each audio source in 3D space.

This application demonstrates a future of broadcast sound experiences over the web, where immersive content is rendered on the client and can be adapted to listener context, as page layout is adapted to device context today with responsive design.
