AGC attack time & recovery time may be adjusted by altering resistor values. Signal input levels cover the range of 1.5mV to 8.3V. The output signal level is close to the consumer audio standard of -10dbV. Schematic of Audio Compression Amplifier Circuit

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 ...

VERSATILE AUDIO AGC CIRCUIT Dave Kenward G8AJN Whilst we spend many happy hours perfecting our video signals, the audio often tends to be an afterthought. For our local repeater a finely adjustable compressor/limiter circuit was required and this article describes what was found to be one of the most versatile solutions.

TL084 Audio Compressor (AGC) – Electronic Circuit Diagram

https://freecircuitdiagram.com/3063-tl084-audio-compressor-agc/

TL084 Audio Compressor (AGC) Compressor or AGC (automatic gain control) is used to manipulate the average amplitide of audio signal, to produce relatively constant volume of signal from high dynamic signal source. The 2N3819 JFET (which is used as a voltage controlled resistor) is the key component.

Automatic gain control for LM386 amp ... - All About Circuits

https://forum.allaboutcircuits.com/threads/automatic-gain-control-for-lm386-amp-based-on-source-volume.122121/

Automatic gain control for LM386 amp based on source volume. I'm trying to build a VU meter, or a VU tower. As of right now, I have LM386 wired to LM3914 in the usual way. The both have a 10k potentiometer, one for fine tuning LM3914, and another for volume control of LM386. Here's the issue: the LEDs are working fine when source audio volume ...

Simplest AGC for op amp | Forum for Electronics

https://www.edaboard.com/threads/simplest-agc-for-op-amp.320200/

Current schematic: What is the purpose of C10? In the schematic the U1 has a fixed gain and U2 uses a pot to adjust the gain. What I would like to do is use a simple AGC (probably FET as VCR) and vary gain of U1 (x10-100) 20-40dB and keep U2 gain at 40dB.
