Abstract: An audio derived AGC signal for controlling RF and/or IF amplifiers in the radio receiver wherein a first control signal is developed by a circuit having a relatively slow response time when the audio output signal is below a predetermined value and a second control signal is developed by a circuit having a relatively fast response time when the audio output signal is at or above the predetermined value. The control signals are developed across a storage capacitor and a circuit is connected thereto for quickly discharging the capacitor when no signal is being supplied from the audio circuit.
