Adafruit Electret Microphone Amplifier - MAX9814 w/ Auto Gain Control. This fancy microphone amplifier module is a step above the rest, with built in automatic gain control. The AGC in the amplifier means that nearby 'loud' sounds will be quieted so they don't overwhelm & 'clip' the amplifier, and even quiet, far-away sounds will be amplified.

Delayed Automatic Gain Control

Automatic Gain Control PreAmplifier Circuit Diagram The preamp circuit uses an easily obtained 741 op amp set for an internal gain about 200.

Automatic Gain Control: Techniques and Architectures for RF Receivers

This project uses an LM3915 bar-graph IC driving two sets of ten LEDs for a 30dB range. The circuit is unique because it has an additional range of 20dB provided by an automatic gain control to allow it to be very sensitive to low sound levels but it increases its range 20dB for loud sounds.Read More
