An acoustic correction apparatus processes a pair of left and right input signals
to compensate for spatial distortion as a function of frequency when the input
signals are reproduced through speakers in a sound system. The sound-energy of
the left and right input signals is separated and corrected in a first low-frequency
range and a second high-frequency range. The resultant signals are recombined to
create image-corrected audio signals having a desired sound-pressure response when
reproduced by the speakers in the sound system. The desired sound-pressure response
creates an apparent sound image location with respect to a listener. The image-corrected
signals may then be spatially enhanced to broaden the apparent sound image.
