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.

Automatic Level Control (ALC) /Automatic Gain Control (AGC): A circuit inserted in the preamplification stage of the recorder that quickly and automatically adjusts the recording levels to adapt to changes in the audio source signal. This function will work instead of the manual level adjustment capability and will boost a lower end signal as well as protect a hotter signal from …

Audio level meter VU Meter - This circuit uses just one IC and a very few number of external components. It displays audio level in terms of 10 LEDs. The input voltage can vary from 12V to 20V, but suggested voltage is 12V.
AVC Automatic Volume Control Circuit - ElectroSchematics.com
https://www.electroschematics.com/automatic-volume-control/
The circuit is used to automatically control the volume levels of cassette recorders, audio tape recorders, amplifiers or radio devices. The AVC circuit works this way: the FET (t1) is used as a variable resistor. The resistance between the drain and source of T1 can be between 150Ω and infinite.

https://www.ti.com/lit/an/snaa028a/snaa028a.pdf
Automatic Gain Control (AGC) Overview www.ti.com 1 Automatic Gain Control (AGC) Overview A microphone is typically used in an environment where the level of the audio source is unknown. The LM4935 features an Automatic Gain Control (AGC) circuit that addresses this situation by compensation for significant variations in level from a microphone’s input.
Automatic Gain Control - AGC Circuit - ElectroSchematics.com
https://www.electroschematics.com/automatic-gain-control-agc/
Automatic Gain Control or AGC is a circuit design which maintain the same level of amplification for sound or radio frequency. If the signal is too low the AGC circuit will increase (amplify) the level and if is to high will lower it to maintain a constant level as possible. The Automatic Gain Control principle is widely use in AM receivers and sometimes AGC is called …
Automatic Level Control (ALC) Circuit - QSL.net
https://www.qsl.net/dh1dm/alc/index.html
Automatic Level Control (ALC) Circuit. Idea and Background. Under normal operating conditions, most transceivers use an ALC circuit to control the output power of their amplifier stages. Forward power is sensed at the output of the final power amplifier, converted to a DC voltage and fed back to the variable gain IF-stage to automatic control ...
