Audio record
Hello Long
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 is stereo and volume too low at 80.3db.
If you are using a Windows computer, you should download and use Audacity rather than Voice Recorder and an online converter. It is unlikely that you will be able to use that combination successfully to make LibriVox recordings.

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. Please follow the instructions here: viewtopic.php?t=90874
I will come back and review it for you.
