Hedrot is an inexpensive head rotator that you can build yourself and attach to any pair of head phones, based on a small microcontroller (a Teensy) with an attached sensor board that measures your head’s rotation, pitch, tilt, etc. Using the Hedrot, you can monitor a binaural version of an ambisonic mix in a pair of headphones and be able to move your head around inside the sound field. In this tutorial we will cover how to set up the Hedrot application to send it’s sensor data via OSC to Reaper to rotate our ambisonic mix with our head movements.
