Audio Compression Amplifier /AGC - ElectroSchematics.com
https://www.electroschematics.com/audio-compressor-agc/
This is an audio compressor/AGC (automatic gain control) with an astonishing 75db input voltage range. A P-Channel JFET is used as a variable resistance element that is applied as a variable attenuator. Distortion is minimized by keeping the signal voltage across the JFET extremely low (1.3mV). This is an improvement over similar circuits that place the …
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.

Project Objective. The objective of our final project is to develop an automatic gain control system, which includes a Raspberry pi model 3, an audio amplifier, an analog to digital converter (ADC), a digital to analog converter (DAC), and a speaker. Our primary goal is to build a system that can protect speakers by reducing the gain on the audio amplifier when distortion is …

preamplifier gain when the input signal level is below the noise floor as set by the NOISE_GATE_THRES. The decay time is the amount of time between each step to increase the gain. It has a range from 32ms to 4096ms. 3.6 AGC_MAX_GAIN (bits 3:0(0x09h)) This bit sets the maximum gain that the AGC can apply to the microphone preamplifier. The maximum

Many characteristics of Automatic Audio Gain Control-such as frequency response, input and output impedance, signal-to-noise ratio, and harmonic dis- tortion-are similar to those of ordinary amplifiers. It is essential in the meas- urement of some of these either to block out the control circuit or else to employ
Automatic Gain Control (AGC) in Receivers
https://www.qsl.net/va3iul/Files/Automatic_Gain_Control.pdf
• Gain control is generally distributed over a number of stages, so that the gain in later stages (the IF amplifiers) is reduced first, and the gain in earlier stages (RF and first IF) is reduced only for signal levels sufficiently high to assure a large S/N. • If the RF gain is small is enough switching in/out an attenuator at RF only for sufficiently high signal levels. Variable gain control for the …
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 an …

Automatic gain control for LM386 amp based on source ...
https://forum.allaboutcircuits.com/threads/automatic-gain-control-for-lm386-amp-based-on-source-volume.122121/
AFAIK: the LM3915 with logarithmic response was the usual thing to use for audio work. An alternative to the LM386 is the TDA7052 BTL amplifier - the type with A suffix has DC volume control and isn't too difficult to rig for AGC. You can use the BTL amp single ended, but at reduced power output. Like Reply Thread Starter Predrag Beočanin
