Welcome Ms. Crumble
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 125kbps variable bit rate. There is also too much background noise. The volume is within range, although on the high side at 91.1dB.
Try to isolate your mic from the noise, such as computer fan. If that isn’t entirely successful, use Audacity’s Noise Removal filter to reduce the background noise about 10db. Noise removal instructions are available here: https://wiki.librivox.org/index.php?title=Noise_Cleaning. A video tutorial on Audacity noise removal is available here: https://youtu.be/rvhqw7zBmEo
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.
With Checker open, go to Validation>Choose Validation Methods and check Background Noise. Be sure to leave 5 seconds blank at the end of your recording.
Please make a new test recording and post it in a reply to this message. I will come back and review it for you.

Hi there.
Thank you for the welcome and the detailed note! I've changed the exports settings here -- it was "average" instead of constant that I clicked on, oops.
https://librivox.org/uploads/tests/test_bumblecrumble2.mp3
It passed with the volume warning in the checker app. Would you please let me know if it's too loud or quiet (and perhaps also how to tell what the decibel volume is)? I can't tell from looking at the graph and I can't figure it out.
All the best, Bi.

The volume is too low at 84.9dB.
A fairly foolproof way to set perfect volume is to go to Effects>Loudness Normalization, choose RMS and enter -23dB (Checker uses a different scale - this is the same as +89db). Do this as the final step before exporting your MP3. I use RMS Normalization on all my recordings.
So try that on your last test and upload it.

Hi again
Thank you for your patience. Checker says it passes so I hope that means the volume passes too?

It does.
You are good to go.
Happy narrating!
