Abstract
An audio imaging method and cognition interface for two-loudspeaker playback is intended for use with standard stereo recordings. The process applies new azimuth-based equalization and phase measurements specifically derived for stereo playback while faithfully interfacing with and eliciting human psychoacoustic localization responses via the Fletcher-Munson loudness effect. The process accurately recovers and reproduces three-dimensional sonic image locations inherently encoded in standard recordings so that a listener may accurately perceive the three-dimensional sound. Sound images are reproduced in at least the forward 180° free-field environment of the listener. The apparatus is designed to allow reproduction of atypical recordings made with closely-spaced microphones if desired.
