I cut off the last three seconds of silence. Some of tools work on overall loudness and density of show sound, so putting a lot
of silence in the show can throw them off.
Your microphone creates tons of low tone rumble. I can't tell if you live near an airport or metro-rail (or the microphone just does that), but first step is apply a custom rumble filter.
I applied a custom RMS (loudness) filter that jacks the loudness up to pass ACX.
Then I applied Audacity normal Limiter to tame those unruly blue wave tips (too tall).
Then I went to make tea.
I did not find any Yeti Curse beeping or other whine sounds. You may have killed those when you got closer to the mic and/or louder in live presentation. So I didn't need the Yeti Curse filter or Trebor's custom programming (cousins of each other). The closer you get to ideal in real life, the less patching, correction, and filtering you need.
=============== Details ====================
— Get and install SetRMS and LF-Rolloff.
Custom Rumble FIlter:
Effect > Equalizer: LF-Rolloff for Speech > OK.
Apply SetRMS and Limiter.
You may have some of those tools already, and this is a little out of order because I don't have a handy, pre-baked kit of instructions to copy and paste. Actually, I do, but it keeps changing.
I think I said earlier, this is only to pass technical specifications. If you think your voice has theatrical or esthetic problems, you can take care of that now, but know that if you go too far, you can throw off the other readings.
The gentle rain-in-the-trees background sound (ffffff) usually passes if it's low enough. They can object if you also have other tones or whiny sound in addition.
That brings us back to finding out if your company follows ACX AudioBook Recommendations. I don't think you ever said.
