Write down how you did the second clip.
Open the first clip in Audacity and View > Show Clipping. All those red marks are permanent sound damage from being too loud. So that's that one. Isn't there some sort of volume indicator on the recorder that changes color or flashes or something to indicate what you're doing?
The second one is good for submission with a couple of simple corrections. Since I was being obsessive, I used three (attached, corrected).
I guess step one is the sound quality which is pretty much perfect after I got done. ACX has a failure called "Overprocessing" where they can hear what you did to your voice. I don't think you're going to get that failure.
I applied a custom filter called SetRMS to force the presentation to meet ACX RMS (Loudness) standards. Then I applied Effect > Limiter to clean up any damage SetRMS may have done (there was a tiny bit). After I did that, the corrected piece meets AudioBook standards.
However. You also have a tiny fan whine or other odd "insect" sound way in the background that I personally didn't like, so I also applied Effect > Noise Reduction at the most gentle settings and that got rid of it.
So now we're down to theatrical reading standards and I think you're pretty much good to go there, too.
I can listen to a story in that voice.
I don't remember where this thread is, but I wrote down the steps in an AudioBook Mastering document.http://kozco.com/tech/audacity/ACXMaste ... ering.html
I did the process all the way through Noise Reduction. I personally would recommend Noise Reduction, even though the reading passes technical standards without it. It just sounds better without that whine.
Have you ever used Effect > Nyquist? It's a tool that just opens up a window and invites you to program your own tool. Conveniently enough, Steve has already written SetRMS and it's up to you to copy and paste the program into the blank window. No, it's not a formal filter or tool yet.
You already have ACX-Check, right? So go down through that process and see where you get stuck. I can't think of a good way to re-write it to be simpler. The top block is comments and notes, the second block is tools and how to install them and the third block is actually doing it.
