Yup not working for me either :(

Well, this is a shame.. Apparently the sample rate of the AudioContext (for some people 48 kHz) isn't definable (it should be 44.1 kHz here), which makes this a tough thing to fix. For me, it works in osx but not in windows 8 (bootcamp).

This is insanely great! Now, imagine if binaural audio was combined with an accelerometer sensor (in the earbud/headphone) so that when you turn your head, the sounds' origins would be adjusted in real time to reflect your new head position. This would be awesome for video games and movies.
To make this work, you would need to record the location of every sound. Easy to do for a video game (where the software knows the exact object or person emitting a sound). But it would be harder for movies, as this sounds localization data would need to be captured on set and handled during all post production work.
I did a little research and a field known as ambisonics (http://en.m.wikipedia.org/wiki/Ambisonics) generalizes this concept to more than 2 speakers. Now that I think about it I remember that the guy behind the xiph.org videos debunking digital audio myths lamenting that not enough research was being done on ambisonics.

I found this: https://github.com/WebAudio/web-audio-api/issues/300
Apparently it's not implemented yet?
