Hello!
Here is my (less than) 1-minute test:

I used Audacity and a USB microphone with my Mac.
Please let me know what can be improved!

Hello Philippa! Welcome to Librivox! :clap:

I have two issues to mention for your recording setup. One is the bit-rate, so when exporting as mp3, please check the format options in the Export Window, and choose "Constant" for Bit Rate Mode, and "128 kbps" for Quality. Then click Save to export and Audacity should keep these settings for all future exports.
The other is the volume, which is on the lower end of the acceptable range, so you should take care not to go any lower. I would suggest bringing up the microphone slider in Audacity (Mixer Toolbar) before recording, just half a notch, so as not to go to the other extreme and become too loud.
If the slider is already maxed up, then I would suggest using Amplification to bring the volume up after recording.
In numbers target volume is 89dB, your test measures about 86, so close enough, but the closer the better.
(Optionally you could use one of the tools that help you measure your volume and guide you by how much to amplify/deamplify if needed. One is the Checker, more information here: https://wiki.librivox.org/index.php?title=Checker This measures the volume of your exported mp3 file. Another one is a plug-in for Audacity, the ReplayGain, more information here: https://wiki.librivox.org/index.php?title=Measuring_Volume_within_Audacity This tells you by how much to amplify (or deamplify if a negative number) within Audacity, before you export.)

If it's not too much trouble, I would like to listen to a new recording to see if the volume is improved. We will also check the bitrate again. You can upload and post here. Thank you!

Hi Rapunzelina,
Thank you for welcoming me and giving me some advice about the recording!
I've set up both Checker and ReplayGain for testing; I can confirm 88.9 dB for this file, but please let me know if there are any other edits that I could make for quality.
