Hi and welcome to Librivox. Your reading is great there are just some edits needed please. If you need any help with this please ask. When you have carried out the edits if you reupload using the same filename that would be great. Thanks

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

The volume is 83 dB which is too low. We aim for between 86-92 dB but ideally we would like it to be at 89 dB.
You will also find the option to amplify under 'effects'.
If you like you can use the checker tool to verify volume and other settings.

Also there is a lot of background noise which could do with removing.
Noise Reduction with free Audacity 2.1.0 and later versions
The method of noise-cleaning has changed radically in version 2.1.0. For a technical explanation see How Audacity Noise Reduction Works in the Audacity Wiki.

If your problem is mains hum or constant whistle, the use of a Notch Filter may help. This should be done before applying Noise Reduction. See Removing Mains Hum
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 all sliders to 6. Hit Preview .

The most likely setting for Sensitivity (second slider) will be 6. If you have very light noise, you may try a lower setting. If you can still hear noise behind your voice, increase the slider.
The most likely setting for the Frequency Smoothing (bands) (third slider) is 6. This equates to the 150Hz Frequency Smoothing in previous versions of Audacity (see above).
Now experiment with the Noise Reduction slider (first slider) and increase it in small steps and preview again and again until you are satisfied with the preview.
A setting of 6 would be very light noise removal - use if you have very little noise
A setting of 12 would be a moderate setting - use if you have moderate noise
A setting of 18 would be a stronger setting - use if you have a nuisance noise, but consider also whether you should have used a Notch Filter before using Noise Reduction (see above). Leaving a little background ambience is definitely preferable to introducing unwanted 'artifacts' and distortions by cleaning too heavily.
Make sure that the 'Reduce' radio button is checked, and hit OK ~- (the effect may take a couple of minutes if it is a long file) -~ Done!

Hi thank you for your new test. There still appears to be background noise in the file. If you are using Audacity then please carry out the following which should solve the problem.

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.

If you need any more help please let me know.

Thanks! I was wondering about how to start a new project, since the initial posts on all those threads have a bunch of different rules listed. Do I have to put that all in too if I want to volunteer to read something that isn't being talked about anywhere on the forum? I was thinking some things by Alexander Hamilton, which I notice there isn't much of here.

Hi we do have a template that you complete with all the details of a book if you would like to do a solo. We do advise that before you embark on reading a whole book you contribute some files to projects which are already set up just so you get the feel for how long things take to record and edit etc. This just gives you an insight into how everything works. There is a link below to Alexander Hamilton projects that are either in the catalogue or in the process of being completed.

If you need any more help please ask happy to help with your Librivox journey.
