One Minute Test
Hi 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, 44.1kHz sample rate, mono, and between 86db and 92db, preferably 89-90. Your test audio volume is too low at 73.8db.
Adjust the input gain on your mic interface so your raw recording has wave forms that peak at about the -3db marks in the track window:
If necessary, adjust the volume level before exporting by normalizing to -23db RMS. Your test was -38db RMS.
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.
