And the DropBox submission passes.

This file wouldn't fit on the forum because you didn't stop at ten seconds. It's over 16 seconds long.

Aha-I had made the mistake early in the process of recording to stereo before realizing I should’ve done it in mono and I saw that ACX says pick one or the other, so I just went with it as is. So far when I’ve submitted things to the site proper in the project tab, they have been accepted. No issues either in the audio analysis tab. I have raw WAVs of each edited chapter and can split them to mono and resubmit before the final full submission if needed. I can also do a Normalize pass at a -3.5 as well to be safe, if needed. Sorry about the file being to long, I did it quickly, but thought I’d cut it to 10 secs. Alas.

We will indeed share a laugh when this is figured out! Away from home now, but I’ll give a look at everything on my computer when I back and make sure I’ve answered all that I can.

To cover this. Record the best way that works for you. Apply the Audiobook Mastering Suite either from here...

https://wiki.audacityteam.org/wiki/Audiobook_Mastering

Or the short form here.

You will find that the settings stick and you only have to type them all in once. Mind the Loudness Normalization RMS/LUFS display bug


Drag-Select some portion of Room Tone and Effect > Noise Reduction > Profile.

Select the whole performance or chapter > Effect > Noise Reduction > 6, 6, 6 > OK.

I'll go back later and see if I can sort why the two sound files are so different. Nothing leaps out. That should not be happening.

If you're recording from an H2n I don't think you have any choice. It's a stereo microphone and if you force it to mono during the recording, you may get loudness and clipping damage.

There is another way to "convert" from stereo to mono. Tracks > Mix > Mix Stereo down to Mono. That has the advantage of leaving the voice where it is and reducing microphone hiss noise.

The noise reduction is not quite half. Wouldn't it be a kick if that was the difference between the two tracks. Garage Band is supplying Two-Track Mono and Audacity is presenting Real Stereo. There would be a significant noise difference between those two, but they would look the same.

As always-sage advice! I will tinker when I’m able. I’ve got three chapters to edit and mix so it may take a bit of work on my part, but I’ll report back. I did find some of these nuggets here on the forum with those mixing settings and the mighty Lucifer-esque 6/6/6 setting when I started, but couldn’t figure out why they didn’t seem to work for my files. It’s been quite the learning curve. Whatever I’ve done, seems to be working so far. But of course, I could be in for a rude awakening if when all is submitted, I find they don’t accept what I’ve done. We’ll see.

Being loud enough, quiet enough, etc is only the hardware test. Like do you know how to "microphone." That gets you in the front door. You still have to read in an entertaining manner and not have voice distortions or mouth noises. ACX hates "distractions," and you are producing a product for sale.

I don't remember if I mentioned this or not, but your book has to be available on Amazon in paper or eBook and there are forbidden books. Scroll down.

No cookbooks, technical manuals, or yoga chants.
