hi there :) welcome to the forum. With a forum name like yours, I already notice that you are really eager to get started.

First off, your reading and voice are very nice to listen to, I really enjoyed it. :9:

However, we need to work on the input volume, as it is only at 77 dB, while we need something in the range of 86-92, with a preferred average of 89 dB.

Could you please amplify your test (don't re-record, work on this one):

> highlight your recording
> go to Effect
> go to Amplify
> input 10 (in your case) in the first slot (amplification dB)
> press ok

Now unfortunately, the background noise, which before was quite ok, is amplified by 10 as well, so we need to do a round of noise-cleaning, which is also very easy in Audacity. Try this:

> select a small portion where you don't speak (usually at the end of your file)
> go to Effect - Noise Cleaning
> first select Get Noise Profile
> then highlight the entire recording
> again Effect - Noise Cleaning
> now select OK

that should do the trick :)

Could you please re-upload your file once more in this thread so I can have a second look ?

thanks and if anything is still unclear, don't hesitate to ask

Sonia

Thank you for the quick review, Kitty. Here's round two:

Can I ask how you were able to tell the dB of the final recording?

thank you, that was a fast correction. :thumbs: And all is well now, you perfectly implemented the changes and now it passes all criteria. I'll mark your test OK now and you are free to roam the forum in search of fresh blood...I mean fresh sections to record :mrgreen:

yes you can :)

Audacity has a nice little plug-in which you can download. It tells you exactly by how much you need to amplify to get to the coveted 89 dB. I use it on all my recordings, it's priceless.

Here it is:

Quote:
Replay Gain plugin for Audacity: - http://forum.audacityteam.org/download/file.php?id=4668

1. Save the file to your computer - your desktop or somewhere where you can easily find it.
2. Now browse to the folder in which Audacity is installed. It's probably in C:\Program Files\Audacity) and then open the Plug-Ins folder.
3. Drag the file you saved into the Plug-Ins folder.
4. When next you start up Audacity, you will be able to select the whole recording (Ctrl+A on Windows), then go to Analyze | ReplayGain, and it'll tell you how much to amplify your file to get to about 89 dB.


Also, to check your file after you exported to mp3, we have created the "Checker" program, which checks all the LV specifics. That's what the Prooflisteners all will use, so you can check beforehand whether you will fail or pass and can correct your files already before uploading ;)

Checker can be found here: http://wiki.librivox.org/index.php/Checker

And now, have fun and good luck with your future recordings !

Sonia
