Welcome to LibriVox, Brittany, and thank you for the test! Well done! :9:

There are only two things to fix in the test:
-there is some background hum. It is easy to fix in Audacity! Select a few seconds of background noise only (no speech) and click Effect | Noise Reduction | Get Profile. Then select the whole recording (Ctrl+A), click Effect | Noise Reduction again, and use settings:

Noise Reduction: 10 dB
Sensitivity: 6
Frequency smoothing (bands) 6

and click OK.

-the volume is a bit soft, around 84dB We aim for 89dB and accept a range between 87 and 91. This is how to amplify it: Select the whole recording. Click Effect > Amplify and use the setting Amplification 7. Please make sure to NOT check the box where it says Allow clipping.

Once you have done those two steps, listen to the test. You might find that you would like to do the noise reduction again, in which case that is perfectly ok. (And you can do it, just to compare -- if you don't like it you can always press the backarrow).

Please reduce background hum and amplify the volume, then upload the test and post it in this same thread so we can listen again. You're doing great!
Kathrine
