Hi, I thought this may be of interest to some - I finally found some time to organize some code for real-time ambisonic spatialization and binaural decoding on the browser, using the Web Audio API and JavaScript. I just published the code in Github, you can find it at:
https://github.com/polarch/JSAmbisonics The library is split into 3 parts: - WebAudio_FOA.js: Implements B-format encoding, rotations, virtual microphones, acoustic intensity analysis, and binaural decoding - WebAudio_HOA.js: Implements HOA encoding, rotations, virtual microphones and binaural decoding for a user-specified order - JSHlib.js: A (non-audio) set of functions computing spherical harmonics, Legendre polynomials, rotation matrices for spherical harmonics, and the forward and inverse spherical harmonic transform. It is required by the WebAudio_HOA.js objects. The objects are easy to set-up, it needs a few lines of code to initialize and connect the FOA/HOA blocks. The documentation at the moment is sketchy, but you can see some real-time examples at the bottom of the webpage, and check their page source code: https://github.com/polarch/JSAmbisonics#examples (If the play-button is not enabled, it means that the page is still loading the soundfile..) Web Audio is still WIP, and different browsers implement things differently. I expect it to work on Firefox and Chrome (most likely on Android too), but not on other browsers. Any feedback, comments or recommendations are very welcome. Best regards, Archontis Politis -------------- next part -------------- An HTML attachment was scrubbed...
