In answer to the other question, this kind of noise can happen when the microphone doesn’t get along with the USB service it’s connected to. A USB connection is supposed to supply clean, pure 5 volts from the computer to the microphone to accept sound from the performer and convert it into data. The data then goes back down the cable to the computer. It’s pretty common for the computer to be a little sloppy with the 5 volts and there can be a little data leaking here and there. It’s expensive to filter 5 volts and most people don’t care.
This is the “Let the microphone worry about it” theory.
Scene shifts to the microphone which uses the 5 volts from the computer to amplify the super tiny, delicate voice signal to be large enough to turn into data for shipment to the computer. It depends on the computer delivering clean, pure 5 volts because having the microphone filter it is expensive.
This is the “Let the computer do it” theory.
The problem comes when nobody does it and your high-pitch whine is what happens when computer trash leaks into the voice. I used to call this the “Yeti Curse” because millions of people bought the insanely popular Blue Yeti microphone and a fraction of those people (the ones with sloppy computers) turned up with this whine sound and complained about it on the forum. It sounded like frying mosquitoes, so Mosquito-Killer is the name of the plugin.

The fourth version, I believe is current. I can’t find the author information and there’s none listed in the code. In this case, the problem is so acute that additional filtering is needed. We tried. There is no simple, cheap cure. The only permanent cure is get rid of the computer, the microphone, or both.
