Continued advice, please....I want to improve the sound on concert video

Hello again.

A month ago I received some helpful stuff on working with PE 13, and I have obtained a copy of Steve's book.

Think I will be able to learn it.

PART TWO of my need-to-learn:  How to work with the audio in the video, which is a coffee house concert.
I have glanced into the book and so forth, and I don't think PE contains what I need.

I have this video of two of us playing guitar and singing, and making remarks ("Patter," to my fellow dinosaurs.)

It was shot on a stationary SONY something-or-other, which served pretty well.  But the audio is not always clear.  Much of that is my performance.  This vid is actually teaching me I have to relearn to hit my consonants better, be conscious of my volume---MOST especially when I am talking.

Making better product is a certain aim, but it's a hell of a learning curve, or else get someone really professional in to do the recording.

Meanwhile, I need this video, the decent parts of it, as a demo to send to other venues.

Pretty sure that a general increase in the loudness of the audio will help a deal; but that EQing will help another deal.

I do not see where PE13 has a lot of ability.  It has, looks like, some ability to make it louder, and a 2-band EQ (treble and bass), and some kind of presets to make the "Narration"  or the "Music" dominant.

Here's what I think I need, if you are still with me (I know I'm being yakky!)   I need a way to work on the audio as it plays and I can hear the changes.

I imagine that there's some other program that contains tools for both audio and video (Filmora kind of does, but still don't hear realtime change, or much change at all).  Otherwise, some outside program that will pull off the audio, work with it, and put it back in.   Or you pull off the audio and then put the altered sound back as a substitute audio track, through some miracle of synchronization.    How'm I doin'?  Got to the point at last?

Can anyone advise me on this?

Thanks
