Here is my 1 minute test recording.
I used Windows, Audacity, and a USB mic.
Thank you
1 minute test
Welcome Catherine Mary
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 112kbps variable bit rate, and volume too high at 92.6db.
If necessary, 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.
