Patent ID: 7043031

Claim:
An audio image correction device comprising: a first 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 first left corrected response; a second left high-pass filter in communication with the left input signal, the second left high-pass filter configured to modify the left input signal as a function of frequency over a second frequency range within the left input signal to create a second left corrected response; and a first combiner in communication with at least the first left corrected response and the second left corrected response, the combiner configured to combine at least the first left corrected response and the second left corrected response to create a left spatially corrected output; a first right high-pass filter in communication with a right input signal, the first right high-pass filter 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 first right corrected response; a second right high-pass filter in communication with the right input signal, the second right high-pass filter configured to modify the right input signal as a function of frequency over a second frequency range within the right input signal to create a second right corrected response; and a second combiner in communication with at least the first right corrected response and the second right corrected response, the combiner configured to combine at least the first right corrected response and the second right corrected response 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 an adder in communication with the left and right spatially corrected outputs wherein the adder combines at least the left spatially corrected output with the right spatially corrected output to identify sum information in the left and right spatially corrected outputs.
