Hi!
I've got a new mic Rode NT-USB mini and use Audacity software. Please let me know it the test recording is good enough.

Hello Hanna,

Welcome to librivox. Thank you for participating here. It’s always great to meet new readers.
You have a nice clear voice, I had no trouble understanding you.


I’m sorry, but you need to make change(s) in order to meet Librivox’s technical standards. I’ll tell you what these are and how to address them. You can then upload a new file and I’ll take a look at it. Don’t worry if this takes more than one go to get it right - I didn’t get it right on my first recording either.

Required: There is a lot of background noise. It sounds to me like a fan.
You can listen to the noise by taking a portion of silence and normalizing it (Audacity Effects/Normalize) to that you can hear it clearly. Think to yourself, what is the source of the noise?
There are three things you might try to reduce the background noise. You might need to do more than one of these.

To make the noise visible in Audacity you need to switch the track’s display mode to “Waveform (db)” using the little pulldown arrow just to the right of the track name (prior to Audacity 2.4) or in Edit/Preferences/Tracks/Default Waveform scale: Logarithmic (dB) (Audacity 2.4 onwards). I recommend leaving it there, as I do all my editing in this mode.

Avoid the noise. Move to a quieter room. Turn off the clothes drier. Choose a quieter time of day to record. Set the laptop power settings to “passive cooling”.

Move closer to the microphone, but watch out for those “p” sounds! You should be about 4 to 12 inches (10-30cm) from the microphone. You will need to position it to the side and/or use a pop filter.

Use noise reduction using Audacity 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.


Advisory: There is a noticeable room echo. You can also reduce the relative room echo by speaking closer to the microphone. Or you can reduce this by recording in a room that has a lot of soft furnishings. I hung duvets on the walls and ceiling of my shed to create an acoustically dead space for recording.

Please record and upload a new version that addresses at least the required technical issue(s). If you quote this message in your reply (hit the big quote button to the right of the post title), 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,
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! Thank you very much for your kind feedback and valuable pieces of advise related to avoiding and getting rid of noise.
Unfortunately I have just my kitchen to record the books and there is some boiling equipment that I believe produces the most part of the noise you heard.
So I tried noise cleaning in Audacity. I couldn't do step 3. Killing remaining noises with a Compressor/Expander, because my version of Audacity doesn't have Expander.

Please let me know if this version meets the requirements.
Thanks!

Hello Hanna,

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.

The noise reduction worked sufficiently well. Keep doing whatever you were doing.
You moved a little bit too close to the mic. You are on the edge of popping your p sounds. You might move back 10cm.
The echo is still there. If you're stuck in the kitchen to record (lots of hard surfaces), is there any way you can hang a blanket or towel behind the mic?


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.

Thanks Adrian! I'll think of echo and try to speak not against the wall as I did. I'm not fresh new but got a new mic because I realized I like librivoxing.
Thank you again for you valuable advises. I'm glad you checked my record)
