1 Minute Test Feedback:

Welcome to Librivox and thanks for posting your test file. We look forward to you joining the community!

Reading Feedback:
You have a clear, bright voice.

Technical Feedback:
  • 00:00 The volume of this track is 78.34dB. 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 11dB. 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 85kbps. Since that is not one of the standard mp3 bitrates, you probably selected 'variable' rather than 'constant' bitrate.
  • 00:00 Note (no change needed): There was some light hiss on the recording. It might be the result of a low input volume from the microphone which you have subsequently amplified to hit the Librivox volume range, in which case you might want to look into increasing the source volume (moving closer to the microphone or making sure the microphone is at full volume). Another solution you can apply is noise reduction. This will reduce the hiss after recording but it does degrade the quality of the audio. Be gentle on the amount (I'd say a maximum of 6dB reduction but less is better) - many people overdo it. Another option is a noise gate. The hiss is within what is acceptable for a Librivox recording but I just thought I should mention it.
Once you've tweaked these settings, upload the file again using the same filename (uploading to the same filename is important when you are submitting Librivox files) and post in the thread and I'll check it for you again!

Welcome Kimberly

I reviewed your test sample, and while it sounds good there are some technical changes needed. LibriVox requires audio that is 128kbps constant bit rate MP3, 44.1kHz sample rate, mono, and between 86db and 92db, preferably 89-90. Your test audio is in stereo.

When exporting your MP3 from Audacity, be sure to check Bit Rate Mode - Constant, then select 128kb from the pull-down menu, and check Force Export to Mono.

You can pre-check your audio yourself by downloading the free Checker app: https://cgjennings.ca/projects/checker/
Passed with Warnings is a fail with regard to volume.

Please make a new test recording and post it in a reply to this message. I will come back and review it for you.

would you be able to confirm if I have corrected the recording.

Your audio is still in stereo. It must be mono.

When exporting your MP3 from Audacity, be sure to check Bit Rate Mode - Constant, then select 128kb from the pull-down menu, and check Force Export to Mono.

Please try again.

Ok I believe I found the section were to change the mono. Please let me know if my test recording is good.

I have checked my audio with checker and I believe is good.
