The muting circuit cuts out the background noise, but is released as soon as an RF signal is received. Another form is called 'ducking', common in broadcast systems. If the announcer speaks while music is playing, the 'ducking' circuit partially mutes the music by reducing its level to some preset value that can be set with a pot.

Types of muting circuits Obviously, the function of muting circuits is to mute (kill) the audio signal. This can be done in a number of ways including switches, relay contacts, junction FETs, analog switches and bipolar muting transistors. Switch and relay contacts can be noisy and intermittent due to contact bounce.
Preamp Muting Circuit | audioXpress
https://audioxpress.com/article/preamp-muting-circuit
Figure 1: Schematic of a simple circuit for preamp muting. The Circuit. The circuit draws its power from the raw supply rails of the existing preamp, drawing only 7mA of current; you can adjust it for a range of operating voltages by simply changing the value of the zener diode. No connection to the preamp’s GND is needed, so there’s no ...

While playing, if their is any sound into microphone, audio will become mute. After the sound from microphone is stop, the audio will be increasing its volume rapidly to its initial volume for some seconds. So, can you guide me some sir? This circuit is connected directly to amplifier, if possible it uses power supply from amplifier.

The circuit should mute sufficiently any audio from 15 hz to 20 khz. If not, you don't have the circuit wired correctly. the 33k and 1M0 resistors (R3 and R4). The fade will be low in distortion until -20 db has been reached. At this point some distortion will …
where to place mute circuit? - diyAudio
https://www.diyaudio.com/community/threads/where-to-place-mute-circuit.323336/
jimmy audio. Where is the best place to implement a relay based mute circuit? right at the input jacks before the summing amps/volume control or after the summing amps/volume control right before the amps (6x)? Relays (3x dpst) will short the inputs to ground. Kinda worried about shorting the op amps outputs (JRC 2068dd) to ground.
Muting Relay PCB - Pete Millett's DIY Audio pages
http://www.pmillett.com/muting_relay_pcb.html
DIY Audio Home. Muting relay PCB. NOTE: The BOM and schematic incorrectly calls out 1N5821 rectifier diodes. These don't mechanically fit on the PCB. use 1N5817 or silimar 1A diodes instead. With cap-coupled preamps and single-ended power amps in particular, there is often a "thump" heard in the speakers when powering up.
