Hi Hannah, welcome to librivox
You do have a couple of tech specs to fix before you are ready to record
The bit rate should be 128 kbps. When you export, change 'quality' to 128 kbps
The recording should use a constant bit rate. When you export, change 'bit rate mode' to 'constant'
Audacity should remember these settings for future exports
Your volume is a little on the high side. We aim for 86 - 92dB (with 89 being the goal) and this is just over 92dB. You might want to turn down your recording volume a little. The checker tool can tell you the volume of a recording, if you want to install that

Please upload a new test once you've fixed the above and post the link here
