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:

It's a 2nd-order ambisonic microphone. Does anyone else have a virtual microphone processor for 2nd-order (or higher) B-format?
