Hi, I'd really appreciate it if someone could give this a listen - I'm on a Windows laptop, using Audacity and a USB Blue Snowball mic.

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 recording should be in mono not stereo

There are some spikes in the file which it would be good to remove using compression in Audacity. To do this follow the video below which is created by Phil Chenevert and is easy to follow.

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
The volume is 94dB, which is too high. We aim for between 86 - 92dB, 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 https://cgjennings.ca/projects/checker/

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.

It would help if you could remove some of the background noise to do this carry out the following.

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.

Ah apologies, the first version was coming out as 89db and I couldn't hear any background noise, I didn't realise the compression would affect it so much! I think I've sorted it now!
