Recorded audio volume goes up and down

Using the newest version of audacity on Windows 10. Recorded audio volume goes up and down after amplified and saved. It’s hard to explain but it had a weird ebb and flow. Not too noticeable but it is for myself and a few other people who listen to it. I’m at a loss, don’t know what to do.

after amplified and saved.

Amplifying & saving shouldn’t cause that… It’s probably happening during recording, so make sure any [u]Windows Enhancements[/u] are turned off.
