I am using Adobe Audition on a PC laptop with an USB Rode mic

Welcome Michelle

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 192kbps. The volume is barely under the maximum at 91.8. There is a bit too much background noise, which sounds like a 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

When exporting your MP3 from Audacity, go to File>Export Audio. In the pop-up menu select:
Format: MP3 Files
Channels: Mono.
Sample Rate: 44100
Bit Rate Mode: Constant.
Quality: 128kbps.

These selections will be saved for future exports.

See the pinned post at the top of this forum for screen shots of these menus and settings.

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.

This is my cleaned up test. I think I fixed everything, still a bit wary of the volume. I am using ADOBE AUDITION.

Okay, you are good to go. The volume is fine.

In Audition, you want a loudness volume of about -23dB RMS. RMS measures overall volume the way Checker does, but uses the standard scale. I normalize all by audio in Reaper using RMS normalize.

Happy narrating!

Thank you!!!
