Hello, this is my test in Czech language:
https://librivox.org/uploads/tests/test_annacerv.mp3

I work on Windows laptop with built-in mic + Audacity. Voice enhancement turned off, no editing.
I tried an analog mic too, which causes so much noise you can't almost hear the speach. Maybe I will need to buy a better one if this built-in version doesn't quite do it. What do you think?
Thanks for any feedback!

Hello Annacerv,
Welcome to librivox. You have a nice clear voice, and I would understand you if I understood Czech.

You need to make some changes in order to meet Librivox's technical standards.

Required: The file's format is MP3 stereo 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: 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 ! If there is a lot of noise that is not coming from the environment, but your microphone itself, please consider investing in an alternative. You can get adequate mics from about $30. I've even got acceptable recordings from a $15 USB Lavallier (clip) microphone.

Please address these 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, I have recorded a number of YouTube videos on this subject.

Hi Adrian,
many thanks for your time and feedback! I have made a new version, please let me know what you think of it.

I hadn't done the Noise cleaning on my previous test because the instructions for the 1-minute test say "no editing" :)
Looking forward to hearing from you again!

Hello Annacerv,

Your changes have been effective.
Congratulations - you meet librivox's technical standards. Proof Listen OK!

-------------------------


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
