Here's the link provided above, I'm using Audacity on a Mac OS system using the built-in Microphone.
Welcome to Librivox Geologist and thanks for posting your test file. We look forward to you joining the community!
You have a mellow, soothing voice.
- 00:00 The volume of this track is 82.24dB. LV requires the overall volume for the track (measured by ReplayGain - you can try this tool if you want to check the volume) to be between 86-92dB (with 89dB being the ideal). The easiest way to fix this automatically is to use the 'Loudness Normalization' effect (set to -19LUFS in 'perceived loudness' mode) in recent versions of Audacity before exporting the track as an MP3. If you use RMS normalization, set it to -21dB. Another way to fix it would be to use the Amplify effect set to 7dB. Since the volume is so low, amplifying it sufficiently would increase the background noise a lot. Did you accidentally have the microphone slider lower than intended or were you further from the microphone than you should be?
- 00:00 Librivox needs mp3 files with a constant bitrate of 128kbps. This file is 79kbps. Since that is not one of the standard mp3 bitrates, you probably selected 'variable' rather than 'constant' bitrate.
Here's the reuploaded version with all the adjustments, still done with the built-in microphone on a mac os on audacity

- 00:00 Librivox needs mp3 files with a constant bitrate of 128kbps. This file is 74kbps. Since that is not one of the standard mp3 bitrates, you probably selected 'variable' rather than 'constant' bitrate.
- 00:00 Note (no change needed): I could hear some mouth noise (clicking sounds). Two things that can cause it are being very close to the microphone so an extra inch or so away can make a difference and also level of hydration (having a warm drink an hour before recording). It's not problematic but lots of readers tend to want to edit it out afterwards so it can be easiest to avoid them altogether. A light use of the Audacity de-clicker can also work after the event.
Hopefully everything should be good now, done on Mac OS operating system, used Audacity, built-in microphone
