On several cable channels, commercials are much louder than normal programming, or the volume level changes annoyingly during a program. Does anyone have a circuit that can be built into a stereo TV to provide an "AGC" function? Ideally, it would be installed by cutting into the low-level L and R audio inputs to the power amp IC (analog signal) and inserting this circuit in-line. Also, it would be great if it could be powered by an available supply in the TV (generally 12V).
