Digital synthesis of binaural auditory localization azimuth cues using headphones
Richard L. McKinley, Mark A. Ericson · The Journal of the Acoustical Society of America · 1988
A laboratory demonstration prototype of a digital auditory localization cue synthesizer has been developed. This synthesizer uses a single audio input that is separately processed in real-time for independent presentation to each ear using headphones. The headphone presented acoustic signals are easy to localize and appear to be out of head. The acoustic image is stabilized for head movement by use of a three-space head tracking device. The paper will describe the salient parameters of the design. A description of the psychoacoustic and electroacoustic measurements that led to the design will be presented. Human performance data on free field, simulated, and synthesized localization cues will be described and a real-time interactive demonstration will be available for interested listeners.
