Hi,
just a note that I replaced the binaural decoding filters in the examples with
others that fix most of the decoding colouration issues that were very strong
in the first version.
I‘ve also added some Matlab routines that can show how these filters can be

Thanks for the detailed reply, Archontis! Good feedback for us. Yes, sorry, I
did kind of group all of my responses to various comments in this thread into
one reply.
Keep an eye out for an update to our encoder plugin (including 4th order, in
approximately the same range you mention). Every

I re-normalized the decoding filters in the examples, could you confirm if that
fixes the clipping issues you mentioned on your browser?
Best regards,
Archontis

Nice work! It’s great someone is taking the time to put together the
infrastructure for web-based ambisonics. I enjoyed watching your Intensity

Only in a directional sense, and not that much IMO. (vs. "much better")
Using proper encoding filters the range of the dipoles and omni are close to
the ideal ones for up to ~9kHz, for the Sou

Well done Archontis!. I was hoping this could be possible, somebody just had

The examples are (sort of) working for me but sound very low res and dull

Thanks. But I'm curious: any reason why you don't want to use the term
"B-Format" in HOA?
People working with HOA
Excellent work! :-)
The examples are working. The ones for HOA are impressive.
I may "steal" some of your code for ambisonic.xyz ;
I was unable to use Firefox a year ago.

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:
