Such a sweet voice! Befitting to a lady! :D

Welcome to Librivox!

A few points to check:

Bit rate. Needs to be set to 128 kbps Constant. If you are using Audacity, you can set that when exporting as mp3. Check the format option in the Export Window, and choose "Constant" for Bit Rate Mode, and "128 kbps" for Quality. Then click Save to export and Audacity should save the settings for all future exports.

Noise. I am using headphones and I get some background white noise, but I think the Noise Reduction feature in Audacity can clear that nicely. Give it a try and see if it makes any difference to your ears. Here is a picture guide: https://wiki.librivox.org/index.php?title=Noisecleaning_With_Pics#Clean_up_the_Noise:_Audacity_versions_from_2.1.0
Also, prior to recording try to make your environment as quiet as possible, away from running appliances, etc.

Volume. It is a bit on the loud end, and probably that's why the background noise is more prominent, too. You could fiddle with the microphone slider in Audacity, bringing it down half a notch or so, so that the waveform still peaks above the 0.5 mark, just not all the way up/down. Keep in mind that volume can be quite variable, depending on how far you are from the microphone, how strong your voice is at the time, etc, so it may be different from recording to recording. In numbers, target volume is 89dB, your recording measures about 93dB.
[If you feel up to it, there are tools that help you measure your volume and guide you 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 is the one that tells you by how much to amplify (or deamplify, if a negative) within Audacity, before you export. If you check them out, and you have questions, please ask.]

Would you do a new test recording to check bitrate and noise again? Feel free to ask any questions, or, when ready, upload and post here. Thank you!

Okay, I think I have the problem solved. Please take a listen to my new version which I've labeled test 3 and uploaded via the usual route.

Hi Jody! Thanks!

The volume now is on the soft side, so aim for somewhere in the middle between your first test recording and this one. The background noise, however, is now gone! :thumbs:

I still get the bitrate wrong. Are you using Audacity or some other program? In Audacity, you can set that when exporting as mp3. Check the format option in the Export Window, and choose "Constant" for Bit Rate Mode, and "128 kbps" for Quality. Then click Save to export and Audacity should save the settings for all future exports.

Third time's the charm! One more try?

Third time's the charm... however, I've labeled this take #4... lol. I'm using Audacity, yes. And I'm 'normalizing' it after I take out the noise.

Let me know if you want it louder still.

That works! It's just within range, so maybe use a smaller value while normalizing, 1 or 2 dB less, I mean if you are normalizing by -5, make it -4 or -3. Out of curiosity, what number to you have now?

But the bitrate is all correct, so your recording setup is ready! You can move on to real recordings! Have fun!

I have it set at -4.

Take care, stay safe,
