Ok. Now a lot of my posts in this category of GTP can be called somewhat inexperienced, since I"m still learning about computers, but this particular topic is something I'm very familiar with. Having done this sort of thing for upwards of 7 years, I've got the lingo. Not trying to toot my own horn, but you get the drift.
First off, NO USB!!!!! USB completely ruins your sound, as the internal connectors pick up frequencies in the recording. NEVER use a USB mic, or USB interface.
What you will have to do is record off Audacity a raw signal. And by raw signal, I mean nothing but the mic, straight into the mic jack of your computer. Now you can pick mics up for around $30 - $40, but they're cheap 🤬. Something decent, but still cheap, will be around $90 - $110. Of course, mics can cost thousands of dollars, so this is still in the cheap price range, but $100 will get you a solid mic that will last you years.
I'll do some research and post again tomorrow some time with my findings. Just remember, NO USB!!!
