Hello Aubry,
Welcome to LV! You have a lovely voice and it's nice a clear.

There are a number of issues to work through. Please let me know if you are using Audacity and I can walk you though the changes.

The volume is too low at 75.5dB. We aim at 89dB with an allowable range of 86-92dB. Please amplify by 14. Alternately you may want to record again with a higher input setting.

The recording should be noise cleaned.

The bit rate should be 128kbps and constant rather than variable.

Please post the revision in this same thread for a double check. If you need help with the changes please let us know what software you are using.

Apologies for all of the mistakes. I do use Audacity, so I’ll fix all of that later today. Thank you!

It's no problem at all. That's why we do these tests. We would hate for you to record longer sections for projects and then have to address these things.

Since you use Audacity here are some hopefully helpful guidance for the corrections.

To get you a little louder. For future recording you can try adjusting your mic positioning or the input level but for this one let’s just amplify. Your recording is at 75.5dB. We aim for 89dB with an allowance of 86-92dB. Highlight your audio. Go to Effect>Amplify>14 ok. Now see how the majority of your waves are about the height of 0.5 to -0.5 (look to the left of the wave on the Audacity program you should see numbers ranging from 1.0 to -1.0) This is the height you are aiming for.

Now let’s do a little bit of noise cleaning. Do you see how your line during the "silent" areas is "fuzzy"? This is a visual indicator there is too much background noise. In the future be sure that you turn off everything you can hear before you start recording. Sit quietly in your recording area and just listen. If you can hear it, so can the microphone.
For this recording try some noise cleaning. Noise cleaning and amplifying are the two most common edits we do.
First highlight some of your "silence", say 0:26-0:27.
Effect>Noise Reduction>Get Noise Profile
Select your entire recording
Effect>Noise Reduction>Play around with the noise settings (using the "preview" button until you are satisfied). I used 20, 6.00, 6. Toggle to reduce noise>OK.
See how the line in your silence areas became a very fine line? That's what you are looking for.

Some of your export settings are not on target. The good news is with Audacity when you get them set, the program remembers them for future exports.
File>Export audio>(wherever you want to save it is fine).
Bit rate should be 'Constant'
Quality 128kbps
Save

In case you are a visual learner here are some videos which may help. They aren't your version of Audacity but should still prove helpful.

I followed your advice, so I'm crossing my fingers that this will work! :)

I didn't hear your first test, so I'm just going from this one and Linny's notes on the other. :)

Bit rate is now correct! :thumbs:

You have a couple plosives. This is when your breath directly hits the microphone on letters like P, F, or TH. Move your microphone a little bit to the side of your mouth if a desktop mic, or a little above or below your mouth if a headset mic. This will help the air pass by the mic instead of directly hitting it.

Did you do the noise reduction? There still seems to be a lot of background white noise in the recording. :hmm:

text instructions: http://wiki.librivox.org/index.php/Noisecleaning_With_Pics

My settings are as follows:
Noise reduction: 10-16 (I suggest about 14 for you)
Sensitivity: [default]
Frequency Smoothing: [default]
Mystery stories: The Master of Mysteries
Kerner Report on 1967 race riots: LINK
Mussolini's speeches thru 1923: LINK
Samuel Smiles Self-Help: Character
Family history: The Medici, Vol. 2

Yes, I did do noise reduction, but I’ll try again sometime later tomorrow. Thanks!
