ABSTRACT:
A stereophonic image enhancement signal processing system for vehicular sound systems provides a symmetrical improvement in imaging for listeners located at the left and right regions of a vehicle passenger compartment The stereo signals are processed in a manner to provide a rapid rate-of-change of phase equal to at least 90 degrees per octave approaching a maximum of 180 degrees between the stereo channels at approximately 300 Hz. A further enhancement of the reproduced sound stage is provided through the application of equalized stereo difference signals prior to, and in combination with, the above described phase shift process. An optional center channel signal, summed from stereo source signals, may be provided for driving a central speaker.
