虚拟理发店（请戴耳机闭眼听）

A binaural audio demo, the 'Virtual Barber Shop', that places a barber moving around your head. It works best with headphones and closed eyes.

Why HN likes it: It is the classic demo HN people point to for showing positional 3D audio working on ordinary headphones.

“try this 3d demo. And don't forget to close your eyes.”
