Hello! Here's my one minute test recording.

I used Logic Pro X (with an expander to reduce background noise), on a mac, with my internal mic.

Welcome mckrisee
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 160kbps, stereo, and volume too low at 82dB. Your noise floor is very low at -74dB, so you may not need the expansion, or at least not so much.
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.

Hello! Thanks so much for reviewing! I've made the necessary changes—to get the volume where it needed to be, I slapped on some gain and a limiter. https://librivox.org/uploads/tests/test_mckrispee.mp3
Okay Lyra, you are good to go. And while your audio sounds okay, you might consider getting an external USB mic.
Happy narrating!
