ABSTRACT:
Spectral imbalance when playing home video versions of motion pictures is overcome by a frequency response correction unit which compensates for the equalization employed during the production of motion picture sound tracks designed for playback over the standard X-curve. In addition, the frequency response correction unit may additionally or instead compensate for listener-perceived differences in the frequency response between the surround sound channel and main sound channels.
