Hi everyone...longtime wannabe but far too inactive volunteer reader. I just submitted a new 1-Minute Test through the uploader -- here's the link: https://librivox.org/uploads/tests/test_rlgreenjr.mp3

As far as equipment, I use a Shure SM58 Unidirectional Mic and a Behringer Xenyx 302USB 5-input mixer, and I recorded my test through Audacity 2.4 software. I look forward to any and all advice and analysis, and to FINALLY begin working with Librivox!

Take care and STAY SAFE!!

Hello Richard,
Welcome to librivox. You have a nice clear voice, full of lively character. I had no trouble understanding you.

You need to make a change in order to meet Librivox's technical standards.


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 much 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 75 dB, and the normal range is 86-92 dB.

Advisory: there is some barely perceptible background noise. If you look at the spectrum of the noise (select some, Analyse / Plot spectrum), it is curiously narrow-band. I say curiously, because I don't see this kind of noise very often. I suspect it is coming from your electronics somewhere.
The first thing to try is moving closer to the microphone, but watch out for those "p" sounds!
The second thing to try is noise reduction using Audacity. 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.
Then 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. I tried 12dB of reduction on your sample, and it worked very well.

Please address at least 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 for participating in Librivox,
Adrian Stephens

PS - If you're interested in developing your technique, and have the time to spare there's a whole bunch of informative YouTube videos.
Our excellent admin Phil has recorded a lot of highly accessible videos (https://wiki.librivox.org/index.php?title=Instructional_Videos).

I have also recorded a number of YouTube videos on this subject, longer (and thereby going into more detail) than Phil's.

Hi Adrian:

I redid the test recording and checked the audio levels through Checker. It passed with 89db (if memory serves me right). As with the earlier test, I recorded the sample lines twice. Hope this one works out. Look forward to hearing from you soon!! :) :clap: :thumbs:

Good Evening Adrian:

This is the message from Checker:
test_rlgreenjr5.mp3

This file has passed the chosen validation tests.
 
What does this mean? The checker program is a first step in checking your audio file for problems. Although checker can identify many common technical problems, passing the validation tests does not always mean that your file is free of problems. The book coordinator, proof listener, and meta coordinator will all make additional checks on the file after you upload it, and they may give you other suggestions as a result of what they find.
Did you need the actual link for the test recording?

Richard

Hello Richard,

This file has a volume of 77dB. The target range is 86-92 dB.
Could you please amplify (Effects / Amplify or Effects / Normalize) it to the middle of this range and repost?

Thanks,
Adrian

Hi Richard! If your file passed the Checker, but the uploaded file doesn't, maybe you uploaded the wrong file?

It won't hurt, when you are available, to make a new test and upload here to check again :) Thanks!
