Patent ID: 7555130

Claim:
An audio image correction device comprising: a left high-pass filter in communication with a left input signal and configured to modify the left input signal as a function of frequency over a first frequency range within the left input signal to create a left spatially corrected output; a right high-pass filter in communication with a right input signal and configured to modify the right input signal as a function of frequency over a first frequency range within the right input signal to create a right spatially corrected output; wherein the left spatially corrected output and the right spatially corrected output are configured to relocate a perceived location of an apparent sound image from a first location to a second apparent location when the left and right spatially corrected outputs are audibly reproduced through a speaker system and perceived by a listener, and wherein the second apparent location is defined by an elevation with respect to the listener that is different from that of the first location; and a combiner in communication with the left and right spatially corrected outputs wherein the combiner combines at least the left spatially corrected output with the right spatially corrected output to identify difference information in the left and right spatially corrected outputs.
