Hello!
Here's my sample using a Condenser mic, Audacity, on a mac! Thank you,

1 Minute Test [OK]
Welcome Robin
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 97kbps variable bit rate, and the volume too low at 83db.
Make sure input gain slider in Audacity (upper right with the little mic icon) is well to the right. Then adjust the input gain on your mic so your raw recording has wave forms that peak at about the 0.5 marks in the Audacity window:
If necessary, adjust the volume level before exporting by going to Effects>Amplify
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 more information.
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.

Here's round two- thanks for the great tips. I used the checker, and it passed, but please let me know if anything needs to change!

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