new test [OK]
Welcome 53
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 settings are all good, however you audio suffers from excessive background noise. It sounds mechanical, like a PC fan.
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
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.
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, thank you for replying. What you heard in the background was my furnace and a ticking clock. It's very cold here.
I've removed the ticking clock from the room and tried to adjust my recording. It seems to be passing the Checker. Here is the link. https://librivox.org/uploads/tests/test_libvox53.mp3
Thanks again. libvox53

Your audio meets LibriVox requirements, so you are good to go.
