Please see my 1-minute test here: https://librivox.org/uploads/tests/1_minute_test_xicote.mp3
I put it through the Checker app before uploading, which deemed it fine - so hopefully it is!
Thanks.
1-Minute Test
Welcome Xicote
Your test audio meets all the technical requirements for bit rate, volume and mono. However, your recording suffers from too much room echo. You need a much deader recording space. The reverberations blur and distort your otherwise good audio.
You can find advice on improving issues like room echo in the Librivox wiki:

Try some of those suggestions, then make a new test recording and post it in a reply to this message. I will come back and review it for you.
