AVC – The featured circuit controls a volume line automatically. It delivers an output voltage of approximately 4 volts peak to peak. This voltage remains relatively constant by input voltages ranging from several hundred milivolts to serveral volts. This electronic circuit is not highly recommended for Hi-Fi applications because its noise factor is way above the …

The purpose of this circuit is to control the relay which turns on the speaker output relay in the audio amplifier...Tomi Engdahl 1998: Audio Level Meter - Audio levels can be monitored using a small panel meter with this circuit built from discrete components. The circuit has a flat frequency response from about 20Hz to well over 50Khz.
Circuit Design: Automatic Gain Control - Engineers Garage
https://www.engineersgarage.com/circuit-design-automatic-gain-control/
The Automatic Gain Control (AGC) amplifiers are another category of amplifiers which can vary its gain according to the input signal level. They provide enough amplification for the weak signals and prevent strong signals from getting over amplified.
An Overview of Automatic Level Control | Maxim Integrated
https://www.maximintegrated.com/en/design/technical-documents/app-notes/3/3673.html
Maxim's Automatic Level Control (ALC) offers two key benefits (Figures 1 and 2). It protects the loudspeaker by limiting the amplifier output power. It boosts low-level signals without distorting the high-level signals. ALC is implemented in the MAX9756, MAX9757, and MAX9758 2.3W stereo speaker amplifiers and DirectDrive headphone amplifiers.
