1-minute test [OK]
Welcome Kelli
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, 44.1kHz sample rate, mono, and between 86db and 92db, preferably 89-90. Your test audio is 106kbps variable bit rate, and the volume too high at 92.4db.
Adjust the input gain on your Solo so your raw recording has wave forms that peak at about the 0.5 marks in the Audacity window:
Then adjust the volume level before exporting by going to Effects>Amplify and enter an amount, or Effects>Loudness Normalization, choose RMS and enter -23db (Checker uses a different scale - this is the same as +89db).
When exporting your MP3 from Audacity, be sure to check Bit Rate Mode - Constant, then select 128kb from the pull-down menu, and check Force Export to Mono.
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.
