Real-Time Audio Spatialization with Inexpensive Hardware

project (Mynatt & Edwards, 1992). The goal of Mercator is to allow visually-impaired computer users to have access to application software packages with graphical user interfaces under the X Window System3. Mercator will accomplish this task by mapping the structures and behaviors of X applications to an auditory and tactile space. An important feature of Mercator will be the use of spatial sound as a primary organizational cue. For Mercator to be useful, this feature must be implemented at a reasonable cost with of f-the-shelf hardware.
