Not especially. I'm more thinking of things that have a potential of being near a live mic, where a cooling fan is a no go, at least without a defeat switch.
The box is called an "audio processor", but in my usage, all I care about is a compressor/limiter. For a mic, probably also a gate. You can get those functions pretty affordably, here's an example I found with a quick search:
Is there a box you can plug an xlr mic into, and have it apply effects like this and output a usable signal? I'd like to move towards a real mic, but setting up filters on each of my work machine, home machine and phone sounds really annoying.
Is this something an rpi would be good for? Is there a writeup somewhere of how to do something similar?
Yes, exactly that. I was in live production for some years, that's where I grew to like the simplicity / bullet proof nature of that style. It would be nice if a manufacturer would release a USB headset that allowed monitoring of ones own voice, and a hardware talk switch.
