The thesis presents the principles, design, implementation, and test results of a prototype three-dimensional audio processor based upon the Analog Devices EZ-KIT Lite digital signal processing development platform. The three-dimensional audio processor simulates a virtual sound source that is free to move in three-dimensional space using a monaural audio source for input, a personal computer and mouse for source position control, and six loudspeakers arranged in a Cartesian array for output. Source distance, direction, and speed cues are produced by the processor using the Inverse Square Law, time delay, loudspeaker mixing, and sampling rate conversion by third-order polynomial interpolation. Test results confirm the performance of the three-dimensional audio processor.
