Welcome Carolyn

I reviewed your test sample, and while it sounds good there are some technical changes needed. LibriVox requires audio that is 128kbps constant bit rate MP3, 44.1kHz sample rate, mono, and between 86dB and 92dB, preferably 89-90. Your test audio is 320kbps, stereo, and volume too low at 83dB.

Make sure input gain slider in Audacity (upper right with the little mic icon) is well to the right. Then adjust the input gain on your mic so your raw recording has wave forms that peak at about the 0.5 marks in the Audacity window:

If necessary, adjust the volume level before exporting by going to Effects>Amplify and enter an amount.

Before you start recording, go to Audio Setup (in the Audacity menu bar), select Audio Settings. In the dialogue box set Recording Channels and select 1 (mono).

When exporting your MP3 from Audacity, go to File>Export Audio. In the pop-up menu select:
Format: MP3 Files
Channels: Mono.
Sample Rate: 44100
Bit Rate Mode: Constant.
Quality: 128kbps.

These selections will be saved for future exports.

See the pinned post at the top of this forum for screen shots of these menus and settings.

You can pre-check your audio yourself by downloading the free Checker app: https://cgjennings.ca/projects/checker/
Passed with Warnings is a fail with regard to volume.

Please make a new test recording and post it in a reply to this message. I will come back and review it for you.

Your audio meets LibriVox requirements, so you are good to go. One note: Your volume is 91.8dB, just barely below the maximum of 92. Reduce by about 3dB going forward to allow a margin of safety.

No need for a new test.

Happy narrating!
