I made this recording with Audacity on a Windows 10 laptop using a usb microphone (Blue Snowball). As suggested in the instructions, it is an unprocessed recording. I look forward to your feedback.

Welcome!

It sounds good, especially for an unprocessed file. :) Some adjustments to make:

1. Volume is slightly low. Can you bump up the mic slider in the Audacity window, maybe 1/2 notch? Not much...

2. You've got some fairly low toned noise. Is your mic sitting on a hard surface? If so, try putting a folded cloth (face cloth should work) under it, to absorb vibrations from the desk.

3. Go ahead and try some noise reduction.
Here are a couple resources:
text instructions: http://wiki.librivox.org/index.php/Noisecleaning_With_Pics
video, but with an older version of Audacity so the settings are different: http://www.youtube.com/watch?v=VFSg9o37HMw

My settings are as follows:
Noise reduction: 10-16 (I suggest about 12 for you)
Sensitivity: 6
Frequency Smoothing: 6

4. Finally, Bit rate is variable; it needs to be 128 constant. This is set when you export to MP3. When you go to export, on the screen where you enter the file name for the MP3, change the Bit Rate mode to Constant, and the quality should be 128 kbps. You should only have to set it once; it'll remember the setting until you change it again.

Try making these adjustments, then post another test. Use the same file name as your previous one, and post in this same thread when it's ready. :)

Thanks for the warm welcome, TriciaG. I'll give it another try using your suggestions. :)

Here's my second try. The volume is all the way up on my mic, yet it still turned out too soft at first. I need to experiment with getting closer to the mic, even though it creates more clipping. I used compressor (which brought the volume up some), normalize, and noise reduction on this. Let me know what you think.

Well, it's a bit too loud now. :)

And you have some small instances of plosives, where your breath is directly hitting the mic on P or TH sounds. Move the mic a little to the side of your mouth rather than directly in front of it.

So I'd say, readjust your mic a little bit, then watch your volume.

There's a plugin for Audacity that will tell you how much to amplify your recordings, or how far off you are from "ideal" volume. It's called ReplayGain. Instructions for installing and using it are on this page: https://wiki.librivox.org/index.php?title=Measuring_Volume_within_Audacity

Thanks again TriciaG. Replaygain works like a charm--actually, better than a charm. I will also work on relocating the mike to avoid the plosions. Many thanks!

Great! I'll mark this as OK then, assuming you'll have good volume from here on out. ;)
