Solder the free end of the ground lead to the bottom of the tin. Remove the small speakers from the earpieces and discard the speakers and cable. Our ability to perceive the location of sounds we hear is the result of many complex factors, including the spacing of our ears and the acoustic properties of our heads. I started off with a piece of wood (pictured) that was 1m long, 8cm wide and 1.5cm thick. Over the years a number of artists and musicians have worked with the technique, among them Lou Reed on. Binaural recording is the process of recording audio as we hear it. Put recorder into record mode and make distinct sounds into the left and right capsules.
