Hi and welcome to Librivox. Your reading is great there are just some edits needed please.

The bit rate should be 128 kbps. When you export the file change ‘quality’ to 128kbps.

The recording should use a constant bit rate. When you export the file change ‘bit rate mode’ to ‘constant’

The volume is 81dB which is too low. We aim for between 86-92 dB but ideally we would like it to be at 89 dB.
In Audacity you will also find the option to amplify under 'effects'.
How to amplify in Audacity: https://www.youtube.com/watch?v=z_z607awyLw
If you like you can use the checker tool to verify volume and other settings.

In order to amplify it is best to reduce the spikes in your file. To do this follow the video below which is created by Phil Chenevert and is easy to follow. Once you have carried out compression you will then be able to amplify the file to the correct dB.

Also adding in a plug in called replay gain will help you to check your volume in Audacity. The link for the video on how to do this is below.

After you have amplified the file it will increase the current background noise which would help if you could remove it.

Step 1 - Select a piece of background noise
Select a piece of background noise (no speech, breaths or other noises) in your audio.
In Menu click: Effect > Noise Reduction... A dialog will pop up.
Click "Get Noise Profile" The dialog box will close instantly.

Step 2 - Noise Reduction
Press CTRL-A / Command-A to select your complete recording.
In Menu click: Effect > Noise Reduction... again. Note: don't select "Repeat Noise Reduction" -- that instantly applies the default settings; you want to adjust the settings and preview the results before you apply the noise filters.

Set Noise Reduction (dB) to 12
Set sensitivity to 6.00
Set frequency smoothing bands to 3
Choose Noise: Reduce
Click ok
This should solve the problem. Always make sure you listen to files through headphones so that you can notice any background noise that needs removing. I have tried this setting on your file and it works. It would be good for you to do this yourself so that you can hear the difference.

Please could you carry out the edits then upload the file using the same file name. If you need any more help please just ask. Thanks

Thank you for your help! I will do all of these things. Should I upload the file to the same post, or start a new post?
