Hello PreskeAhrenholtz,
Welcome to librivox. You have a nice clear voice, I had no trouble understanding you.

There's a few technical changes you need to make that will improve the recording and make it acceptable.

Required: The file's format is MP3 mono at variable kb/s. The specification we use for all MP3 recordings in Librivox is mono 128 kb/s constant bit rate. You can set this on the "save as MP3" dialog in Audacity, and it will persist the next time you do a save.

Required: The volume is way too low. You can download the checker program (https://wiki.librivox.org/index.php?title=Checker) which you can use to check the volume against the expected range. This recording was 78 dB, and the normal range is 86-92 dB.

Required: There is some noticeable background noise, which can distract from the reading.
You can highlight the noise in Audacity by changing the track's display mode to "Waveform (db)" using the little pulldown arrow just to the right of the track name. I recommend leaving it there, as I do all my editing in this mode.
Please perform noise cleaning as shown here: https://wiki.librivox.org/index.php/Noise_Cleaning. I recommend making this a part of your editing routine. You'll be surprised how much difference it makes, but be careful of over-doing it (more than about 18dB), which can affect the quality.
Normally I'd say you can also move closer to the mic, but I don't think you can without getting unaccepable "popping P" sounds. If there is a lot of noise that is not coming from the environment, but your microphone itself, please consider investing in an alternative. You can get adequate mics from about $30. I've even got acceptable recordings from a $15 USB lavlllier (clip) microphone.

Please address the required technical issues and upload a new version. If you quote this message in your reply, I'll get a notification and will go in and re-check.

If you haven't already, you might spend some time browsing through the LibriVox Wiki. It contains a wealth of great information that you'll find useful and informative about who does what, and various technical aspects.


Thank you again for participating in Librivox

Thank you so much for listening to my test and giving me feedback! I really appreciate it! I changed my settings and cleaned up the audio, along with increasing the volume. Here is the updated version: https://librivox.org/uploads/tests/test_preskeahrenholtz.mp3

Let me know if there is anything else I need to make better or take a look at. Thanks again!

Hello PreskeAhrenholtz,

Congratulations - you meet librivox's technical standards. Proof Listen OK!

--------------

Advisory: There are some noticeable plosives in the "P" sounds (e.g. @4.85s). There are some different ways to fix this: 1) move away from the microphone or position in the microphone to the side of your face; 2) get a "pop" filter in front of your microphone; or 3) repair the plosives as described here: https://www.youtube.com/watch?v=inbSdGb26XQ. Prevention is much easier than cure.

-------------

I suggest you spend some time becoming familiar with the forum and looking for projects that you think you'd enjoy working on. Just jump right in wherever it feels comfortable. Most of all, always have fun. You'll find lots of interesting material to record. If you're like me, you'll also discover you're learning a lot in the process and being exposed to books I otherwise wouldn't have opened or known about. You'll be contributing to an interesting project and interacting with a lot of fun and varied fellow LibriVox volunteers in the process.

Yay!!! Thank you so much!! I'm so excited and can't wait to contribute. I'll keep an eye on my plosives for sure. :)
