Webcam Head-tracked AMbisonics (WHAM)

This website provides an implementation of an auralisation platform using (currently) up to 15th order Ambisonics/Circular Harmonics to enable head rotation of 3D binaurally scanned real, or synthesised, spaces. Development of the site, and capturing of the room responses are by Mark Dring and Bruce Wiggins, University of Derby, UK.

Webcam Tracking

Your webcam is currently being used to track the movement of your face and position the audio source accordingly. For best results keep your face well-lit and avoid obstructions. Alternatively, uncheck the box to control the rotation manually by moving the puck in the map with your mouse.

Start / Stop audio:    

Select sample: or

Click on the map to rotate the head if not using a webcam:
Azimuth: 0 degrees Elevation: 0 degrees

Azimuth = degrees and Elevation = degrees
