Abstract: A disclosed system and method dynamically controls the perceived volume of a stereo audio program including left and right channel signals. The system comprises: a dynamic volume control configured and arranged so as to maintain a perceived constant volume level of the stereo audio program; and an excessive spatial processing protection processor configured and arranged for controlling the level of a difference signal, created as a function of the right channel signal subtracted from the left channel signal (L?R), relative to the level of a sum signal, created as a function of the right channel signal plus the left channel signal;; wherein the excessive spatial processing protection processor processes the audio signals so as to control the difference (L?R) signal relative to the sum (L+R) signal.

Abstract: A switching circuit for switching a time-varying input signal, the switching circuit comprising: at least one switch including a N-channel MOSFET and a P-channel MOSFET, each having a gate configured to receive a drive signal to change the ON/OFF state of the switch; and a drive circuit configured and arranged so as to selectively apply a pair of drive signals to change the ON/OFF state of the switch, the drive circuit being configured and arranged to generate the drive signals as a function of (a) a pair DC signal components sufficient to change the ON/OFF state of the switch and (b) a pair of time-varying signal components as at least a partial replica of the signal present on the source terminal of each MOSFET so that when applied with the DC signals to the gates of the re-channel MOSFET and p-channel MOSFET respectively, the drive signals will be at the appropriate level to maintain the ON/OFF state of the switch and keep the gate-source voltages of each MOSFET within the gate-source breakdown limit of th
