Experiments in binaural audio for telepresence

One area of telepresence research that has had less, though increasing, analysis is that pertaining to the audio aspects of presence, particularly with regard to the remote detection of real world sounds. If telepresence can be considered as the physical sensation of being elsewhere, whether within a virtual, or real environment then addressing the sensation that provides audio information, whether virtual or real should be a worthwhile endeavour in order to enhance the sense of presence.
