Welcome Harsharanjitk

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 320kbps, 48kHz sample rate, and volume too low at 71.7db.

Make sure the the 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.

Before you start recording, be sure that you select 44100 from the pull-down menu in the lower left corner of the Audacity window.

When exporting your MP3 from Audacity, be sure to check Bit Rate Mode - Constant, then select 128kb from the pull-down menu, and check Force Export to Mono.

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. I will come back and review it for you.

Mark, I moved his test here but just by copying it. He probably will not be notified about your response. I sent him a PM telling him where to find your response but perhaps another PM would help Harsharanjitk2408 is his forum name. Sorry for the conusion.

Almost. he other settings are now correct, bu the volume is now too high at 92.1db.

If necessary, adjust the volume level before exporting by going to Effects>Amplify. Enter a value -3db.

Please try again, and post in a reply to this message and not in someone else's thread. It will just get lost.

So I have to re record for 3rd time? I guess

[sjmarky]

Yes, you do. I need to see a test that passes before letting you record for projects.

[Harsharanjitk2408]

though i tried harder this time but still voice is still running 91.3 db ; but checker passed this test . however, i have to upload it.
