Probably not. The software doesn't speak English and it doesn't know what words are. If you did those words very quietly, you might be able to use Analyze > Silence Finder.

somehow the noise is getting into the microphone's analog electronics. Not even somehow. Cheap, inexpensive microphones that don't cost very much are forced to use the USB power system directly to run the very sensitive microphone electronics. Even with stunningly good power supply rejection ratio,...

how big a WAV file I can fit under 1mb, heh. Just over 10 minutes [correction Seconds ] 44100, 16-bit, mono WAV (Microsoft). That's why the sound clip instructions are written like that. We did do some of the leg work. You know the old microphone died because it was crushed under a Semi/Lorry? Micr...

From that YouTube submission, I'm guessing you're not using Audacity 2.1.0. You can get that from here.

If we start telling you about adjustments and settings, they're going to be for that version.

If somebody asked me cold what that was, I would have said you were talking into the wrong end of the microphone, but that's not likely with a webcam... Most of the stuff behind you that sounds like a working machine shop is the pickup from the room, echoes, computer fans, traffic noises, continenta...

There is a suspicious knob called "USB Thru." What does that do? I'm very leery of people having troubles with very complicated mixers.

"Turns out we had 'Cathedral Effects' in the line and it was knocking the level down."

This just screams you're running the mixer wrong. Where are the sound meters on the right of the mixer? I would be running them at the "0" point. If you have a pleasant mix, adjust the Main Fader (lower right) until the meters bounce in the right place. If you can't get there, then you did...

Audacity clears itself when you close.

Back in the paleolithic, we used to use choppers to turn DC input signals into AC so AC coupled amplifiers and processors could handle them. They were fiddly and hard to manage, but they did work in the face of measurement systems that wouldn't go to DC.

So if you're good with a soldering iron.

It's worse than that. If the signal really is 0, +5v, then the device has to have a power supply system that exceeds that, say +6v and -1v at minimum. Or a prescaller to reduce the input range to 1v, 4v. Good luck finding either of those in a cheap device.
