Hi Len,
you can find a higher-order virtual microphone implementation in our web-audio
ambisonics library, implementing higher-order cardioids, supercardioids, and
hypercardioid patterns. The library is open-source and generates the patterns
for any order, even though Web Audio supports up to 4th-order signals (without
tricks) at that point. You can find a real-time 3rd-order demo here:
https://cdn.rawgit.com/polarch/JSAmbisonics/e28e15b384f2442a66fadc0035439c64ed65fa4d/examples/hoa-virtual-mic.html
If you manage to stream your 9 second-order signals somehow in the browser,
then you can process them live there, but unfortunately I think HTML5 supports
up to 8 channels for streaming audio, so at the moment HOA material works only
with wav/ogg files.
I don't believe this is (still?) true:
https://github.com/GoogleChrome/omnitone
Omnitone offers ambisonic decoding and binaural rendering of:
* First-order-ambisonic stream
* High-order-ambisonic stream: 2nd and 3rd order.
The input audio stream can be either an HTMLMediaElement (<video> or
<audio> tag) or a multichannel AudioBufferSourceNode.

We're introducing OctoMic next week at AES (booth 315). It's a 2nd-order
ambisonic microphone.
Does anyone else have a virtual microphone processor for 2nd-order (or higher)
B-format?
