[PD] spinning sounds around the listener

Yes spinning is easily done with ambipan~ for instance. Since you have
control of the radius (sound distnace) and angle (rotation), the way that
you vary the angle variable determines the speed of course.

This can be "simulated" with two speakers only, for example with binaural
rendering of the audio. With ITD (see the list) the ears are tricked into
believing that the sound arrives from a certain position.

What I found in my implementations, installations, papers is that all this
works better with HRTF models, this means: you know where the head of the
users is. How to do that? OpenCv Head Tracking, IR tracking system with
rigid bodys (by far the best), and recently Microsoft Kinect.

Best regards,
