Isn't this what AmbiExplorer does on Android devices? It renders B format files into binaural, allowing you to reposition your perspective. I know that it supports rendering to a file.

Now I understand. What I did is a player, but what you need is a converter. The principles are the same, except the first is realtime (for listening and interacting) while the second could be much faster but would have to be streamed to a file. The Web Audio API does support offline audio rendering that could potentially be faster than realtime : http://webaudio.github.io/web-audio-api/#the-offlineaudiocontext-interface But I don't know if the result could be streamed to a file. To be verified.
