There's a difference between "how the world really sounds" and how we "want the world to sound".
Short. Sweet: pretty much delete the entire audio recorded with the video and lay in only relevant audio information in various tracks on your editor.
Have a track for the background/ambiance/environment sound you WANT.
You'll likely have to go record that separately.
You might get lucky and can salvage a good length of audio off a take you already have.
In the future just spend a few private moments recording a few minutes of clear ambient audio.
Have a track for key sounds.
Record a drawer being opened, pause, then close it. Adjust timing in your NLE or with an audio editor.
Record a knife being drug across the counter top.
A door handle being grasped and turned.
The door opening and closing.
Tinker with sounds in an audio editor to keep EXACTLY what you want, then build a audio library for each project, and store all of these little tidbits there.
Have a track for dialog.
The on-camera mic is only good for about three to five feet out.
Everything outside that bubble is going to rapidly start sounding like sh!t.
Get a good mic and a friend that can keep that thing just off camera aimed at mouths (not general directions) and pull a good dialog recording.
Ideally, it will have pretty much just dialog and very little else.
No real drawer opening, knife scratching, door handle turning, or door opening sounds.
You're going to put in bogus recreations of those sounds when you edit!
And then a track for your background music, your soundtrack.
Throw this in last so that you can "create" your base non-soundtrack audio to as close to artificially perfect as you want or can.
Welcome to the all fake make-believe world of filmmaking!

Nah, I'm pretty sure he can strip it all out and rebuild it with doctored post-recorded audio.
It's quite salvageable, and a good experiment to practice with.
