How to remove background noise from an mp3 audio file

HI,
I am a transcriber, and I use to use Audacity several years ago. Things have changed since then. I had been out of the work force since about 2011, and just recently have had to get started working again. I can not remember now how to analyze a file in audacity. My husband died May 9, I’ve had so much overwhelming my brain for the last few years because of his illness, I am just lost again. That’s the reason I downloaded Audacity again, in hopes that I could remember how to do that, it really helped a lot when I was working on transcription jobs before.
Please help. Thank you.

I think what we mean by that and what you mean are going to be very different. What do you need to do? Use different words.

Does this help?
