Here is a link to my one minute test. I used youtube tutorials and the wiki librivox page to help me set my audacity settings. I was not sure how to do the volume. I am using Linux and Audacity 2.0.5. I hope this is okay. I have a "Labtec" microphone that i plug into the mic jack on my laptop. I am not very tech savvy but I would really like to do some librivox recordings so I hope that I can figure out what needs to be done. Thanks for any feedback!

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

The volume is 68dB 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:
If you like you can use the checker tool to verify volume and other settings.

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.

When you amplify there is a lot of background noise so it would help if you could remove some of it 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.

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
