Suddenly, after several seconds of recording, the sound will get horrible. I’ve been recording for a while now (several months) without a problem, and can’t think of anything I may have changed. I tested it on two mics and it is the same problem. I’ve tried a few things to no avail, so I throw it out there to see if anybody recognizes the problem and possibly has a solution.
I plug the mics directly into the computers mic port.

That’s Windows voice processing. As you noticed, you probably now have to deal with environment noises, fan sounds and echoes. That’s what voice processing solves.
Voice Processing hates music. It sees any sustained musical tone as noise and tries to get rid of it. So if this is the first time you’ve had to perform music, that’s what happened. Windows thinks your music is air conditioning noise.
That’s Windows default, so if you had a major update or change, Windows may have turned it back on.
