Ok, maybe it's more university than school :hmm: Anyway, you sound very reputable, you should apply for the "Tagesschau" ;)

The recording is excellent, only the volume is a bit too low. We aim at 89 dB within a range of 86 to 92 dB. You can check it with mp3gain or checker, or if you use Audacity with ReplayGain. There is a peak of noise in the beginning that you just can cut out; it might prevent you from reaching the right volume.

Can you please adjust the volume and post a link to the edited file in this thread again? Thank you :)

This is a link to my edited version. I am a university student. Not sure what the "Tagesschau" is, but I will definitely look it up! Thank you for listening and helping out! :D

:hmm: You cut out that bump in the beginning which is good; the volume is still at 76.8 dB :) We definitely need something around 89 +- 3 dB. Imagine, somebody listens to your section and adjusts the volume that he can hear it quite well and then the next section comes with 95 dB or so :shock:

Tagesschau is a German news broadcast; they're looking for really reputable (and confident) readers.

Sorry for having you wait; the weekend was really, really busy.

Now, the good news is, the volume moved. The bad news: it moved to the wrong direction. The recording needs to be louder, not less loud; you have now 73.2 dB, before you had 76.8 dB (we still need 89 dB) :)

Is this a new recording? That is not necessary; it is really sufficient to amplify the existing recording. And maybe a little bit of noise reduction then, to make the listening experience still more pleasurable, but the important thing is the volume.

Which recording software do you use?

I'm using audacity, but having a hard time downloading ReplayGain. I've amplified the recording, but I don't know how loud it is in dB. It might be too loud now.

If you can't figure out ReplayGain, you could also try one of these two tools. They require you to export to MP3 before checking volume, but at least it's something. :)

1) Checker. It's a small program the spouse of a LibriVoxer developed to check the tech settings. If you're game, you can download it and use it to check the volume and other settings. It's here: http://cgjennings.ca/checker/
Use the latest version, which I believe is 0.95. The volume information is in the Information tab.

2) MP3Gain. https://sourceforge.net/projects/mp3gain/ I think it's for Windows, although at the top of This Page there are links to Mac versions.

This latest file of yours is loud enough - 91 dB - so don't go any higher. ;)

At this point it passes our checks, so you're cleared to record. However, to improve the recording...

I would suggest some noise reduction to take care of the background white noise. Here are a couple resources:
text instructions: http://wiki.librivox.org/index.php/Noisecleaning_With_Pics
video, but with an older version of Audacity so the settings are different: http://www.youtube.com/watch?v=VFSg9o37HMw

My settings are as follows:
Noise reduction: 10-16 (I suggest about 12 for you)
Sensitivity: 6
Frequency Smoothing: 6

Try it and see what you think. :)

I see this test is done, right? Thank you Tricia :)
