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:
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.

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?
