Welcome Simple

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 volume is too low at 76.1db.

Adjust the input gain on your mic so your raw recording has wave forms look more like this:

When exporting your file from Reaper, you can ensure perfect volume by selecting Normalize/Limit/Fade in the render menu and selecting Normalize to, RMS-1 and -23db. I use this for all my audio.

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.
