Hi Disha

I reviewed your test sample and some changes are 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 is 69kbps variable bit rate, stereo and just 68.4db.

First, if you have a gain control on your mic, adjust it so your raw recording has wave forms that peak at about the 0.5 marks in the Audacity window. Make sure the recording level in the Audacity window is to the right. If necessary, adjust the volume level before exporting by going to Filters>Amplify. An alternative is to use Filters>Normalize, choose peak and set it to -3 or -4db.

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

You can check your audio yourself by downloading the free Checker app: https://cgjennings.ca/projects/checker/

Please record a new test with the same file name and post it as a reply. I’ll return and review it for you.

Okay Disha, everything is correct except now it is too loud at 94.3db. The acceptable range is 86 - 92db.

Do download and use the Checker app: https://cgjennings.ca/projects/checker/

This can save you a lot of trouble.

Please record another new test with the same file name and post it as a reply. I'm sure this time you'll nail it.
