ABSTRACT:
A digital signal processing technique is provided for symmetrical stereophonic image enhancement in an automotive listening environment. The process introduces a rapid rate-of-change of phase shift between the channels, to a maximum of substantially 180 degrees, at substantially 200 Hertz. As an additional feature, spatial enhancement of the reproduced sound may be provided through the application of modified stereo difference signals prior to the image enhancement process.
