We have developed a system we call Telescopic Spatial Radio (TSR). This system transforms monaural transmissions from geographically distributed speakers into a spatial audio presentation using binaural techniques which preserve the actual physical angles between participants. TSR instantly augments the user’s situational awareness with the headings of the speaking users. The system leverages orientation measuring, location tracking, and signal processing capabilities that are rapidly decreasing in cost. TSR has many potential applications ranging from emergency and aviation communication to a richer consumer experience. We have developed a prototype system using laptop computers, GPS, and electronic compasses. The system allows users to select HRTFs from a library, and operates over a computer network.
