What could be worthwile is to have a look at MAX9814. It is a low noise microphone amplifier as wel as compressor.
They can be bought rather cheap on a PCB, coming with a microphone and several settings like gain, attack and delay time and ratio. The microphone could be removed (as I did in my project that has nothing to to with ATV: https://youtu.be/jP5sGiyjWzc ).
However, I can imagine that a small 3D printed enclosure makes it a great functioning microphone unit for (D)ATV.
