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

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

Advisory: The volume is a little 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 83 dB, and the normal range is 86-92 dB.

Required: the recording shows a high level of DC bias. The checker program can test this for you - but you can easily see it using Audacity and remove it using the Effect/Normalize option.

Advisory: 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. You can also move closer to the mic, this will make a lot of difference - but watch out for those popping "p"s !

Advisory: There are some room sounds at the start and end that can be cut out. Seeing as you will be operating on the file in Audacity, you should use the opportunity to clear (ctrl+L) these sections. It doesn't matter for this test, but it would matter for a production recording.

Please address at least the required technical issue 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

Posted up a new version at
https://librivox.org/uploads/tests/test_stephanossteer.mp3 which meets all the checker requirements so if anyone could check this it would be much appreciated.

Hello Stephanos,

Well done! You meet the librivox technical standards.

Proof listen OK.
------------------------

On a recording proper, you would edit out the opening "noises off", but that doesn't matter for this test.

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.

Thank you again for participating in Librivox
