Hello Emma,

Welcome to LibriVox! Great to have you with us! :)

Than you for your test.

There are several things about it that will require corrections.

First off, the audio. It is in stereo, and we need mono. Please make sure you record in mono. You didn't say what software you're using, and if it's Audacity, then please go to Edit -> Preferences... and change in Devices, Recording, the Channels to '1 (Mono)'. Also, the audio is too soft. The volume is simply too low. Please increase the recording volume so that your recording waveform looks similar to this:

This image is taken from our wiki page with recommendations on how to do 1-minute test. Please read that page and follow the instructions.

Second, the exported file has wrong bitrate. We need the MP3 file to have constant bitrate, 128 kbps. If you're using Audacity, the settings are on the Export dialog box.

See if you can make those corrections. Before you upload you can check the file itself using Checker software. Read that wiki page, download and install it so you can check your own files.

When you have made corrections, please upload the file again and post a reply here in this thread.

You're on the right track. :)

Hi tovarisch, thank-you for your feedback. Here is my second attempt (after a long delay where I had bad internet). I made all the changes recommended - hope it is correct now?

Hi Emma,

Welcome back!

Yes, this is most certainly an improvement over the first one. Everything is pretty much where it's supposed to be, except now the volume is a touch high, just a tiny bit. Select the entire track and amplify it by negative 3 to get it in the range.

There is also plenty of extraneous sounds and background noise. Sounds are better avoided, so when you are ready to record something for real, try to do it after switching off other devices that make sounds (TV, radio).

If you want to learn it, noise cleaning is described nicely on this wiki page.

At least please get the volume in the range.

Did you download and install Checker yet? You should...

Hi tovarisch,

Thanks for the feedback again.

I've tried installing the checker but my mac blocks it. Will try again if essential.

Hi tovarisch,

One more question. Should I always amplify by -3 (that seemed to work well) or adjust the computer or audible input volume?

Many thanks,

Emma

tovarisch,

I have a Mac and was able to download Checker. Is is telling you the download is blocked?

Try downloading it again. Once you get that message go to System Preferences, click on Security and Privacy. On the General page near the bottom you should see a message that the download is blocked and give you the option to download it anyway

Have fun!
:clap: :D

Have figured almost everything out and started recording. Still one question remains. I've done a few tests with different volume levels and can't get it to be perfect without amplifying (it's always either slightly below or above the ideal range). Is it acceptable to always amplify a recording?

Yes, Emma, it is perfectly fine.

The setup I use, for instance, does not get me in the proper range due to its specific design limitations. I think it was done on purpose. So, I just record as is, and use ReplayGain plugin to tell me how much to amplify. My main concern is not to cause it to clip. So, it's better to record at lower levels, then amplify and clean the noise, than to try to be "right there" and then get your recording clipped - clipping cannot be corrected in post-processing.

Is this thread ready for the "OK" in the subject line? I'm a bit confused. :)

No, not yet. The last uploaded test is too loud.
