Abstract
A circuit for providing enhanced stereophonic sound by processing the L-R signal. A compressor which receives the L+R signal provides a gain control signal. This signal controls the level of the L-R signal and the gain in a tracking VCA. The tracking VCA receives the enhanced L-R signal and under predetermined conditions prevents increasing the level of the L-R signal.
