Hello Andrew,
Welcome to librivox. You have a nice clear voice, I had no trouble understanding you.
I could sense a theatrical edge to your voice. I look forward to meeting you in the Plays projects.

Congratulations - you meet librivox's technical standards. Proof Listen OK!
-----------------------
You can stop reading here and get on with recording. I have additional comments that you can read if you want to develop your technique.


FYI, the file name should be all lower-case. This doesn't matter for this test recording, but is a uniform standard for actual recordings.

There is some background noise. It's on the edge of being acceptable - you won't hear it in a car, but you will hear it using headphones in a quiet room. The noise appears to be a mixture of traffic (20Hz) and mains hum (50Hz), probably from a fan or motor.
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.

If you want to upload a new version and 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.

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. I recommend starting with short works, such as poetry and dramatic readings.

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.

Adrian,
Many thanks. I've done noise reduction and will post the new version. How do I quote your message in my new posting?

Following feedback, I've done noise reduction on my 1 minute test. Here's the cleaned up version. Please listen to it.

Hello Andrew,

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 68 dB, and the normal range is 86-92 dB. You can use the Effects/Normalize audacity feature to adjust this.

Advisory: The noise is still audible. I did a further round of 12dB noise reduction and it removed the noise to a level that I don't notice
it without damaging the speech quality. You might increase the noise reduction or do two rounds yourself.

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.


Thank you for participating in Librivox,

Hello Andrew,

Hello,

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

You can stop reading here and get on with recording. I have an additional comment that you can read if you want to develop your technique.

The noise is still there. It's a marginal pass on this test. I did 12dB of additional noise reduction on your latest file, and it reduced noise to a level that is no longer noticable. If you are going to spend time recording and editing your work, it's certainly
worth spending the extra minute or so in post getting the noise to a level you don't notice it.


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.
