Hi, welcome to librivox :D

You're sounding great but there are some things that you will need to fix.

The bit rate should be 128 kbps.  

The recording should be in mono sound, not stereo sound.  

The recording should use a constant bit rate rather than variable bit rate.

The volume is too low at 73dB. It should be 86 - 92dB (with a goal of 89)

If you need guidance on how to fix these, please let me know which software you are using to record.

If you know how to correct these then please do that and post a link to the updated test here :)

Hi! thank you for helping me out! I am using audacity with a blue snowball microphone.

Can you let me know how to make the changes on audacity?

Bitrate: when you export, change 'quality' to 128 kbps

bit rate mode: When you export, change 'bit rate mode' to 'constant'

mono sound: go to 'preferences' 'devices' and change 'channels' to mono.

Aduacity should save these settings so you don't have to change them every time

Volume: You will probably want to turn up your recording volume. You could do this in the settings of your computer but there is also a slider in audacity. it's next to an icon of a microphone. You will also find the option to amplify under 'effects'

You might like to install the checker tool https://cgjennings.ca/projects/checker/ which is able to tell you the volume of recordings

All is correct now but you might like to run noise reduction as you do have a little background noise. Instructions for noise reduction can be found here https://wiki.librivox.org/index.php/Noisecleaning_With_Pics

If you decide to noise clean you might want to upload another test just to be on the safe side. If not, you're now okay to record for projects :D
