This microphone takes 48volt Phantom Power, so you have that button pushed, right?
This is one of the systems least likely to have noise problems like this. Usually, someone buys a cheapo USB adapter and it has trouble with the computer and starts making noises. That's not how yours works.
OK, lets start with the obvious. Your recording is very
low. You are intended to adjust your PreSonus volume controls so the Audacity panel looks roughly like this.
While you're presenting, the bouncing light sound meter is supposed to get close to -6dB every so often like in the illustration. Also the tips of the blue waves should get about to half-way every so often.
See the little red "CLIP" light on the PreSonus? That's your sign that you are presenting too loud. So there are little indicators sprinkled around as a guide for good announcing.
Being a practicing obsessive, I would stop Audacity and adjust the preSonus and announce louder and louder until the red light comes on just to see how much work I need to do to get it there. I'm betting you would have to turn the PreSonus all the way up, get close and bellow into the microphone to make that light come on, but it's good to know those conditions. None of this will damage anything unless you scare the cat. The CLIP light is never
supposed to come on during a performance.
Which three-number Audacity do you have? Is it possible to try a different USB connection? Do you have a lot of USB connections, like maybe external drives or a coffee warmer or something? More than a keyboard and mouse?
