This was done on GarageBand using an AT2020 microphone.

Welcome to LibriVox!

I don't know GarageBand but I can provide you with feedback. If you need help with making the adjustments just ask and I'm sure someone else can assist.

Your recording is in stereo and we need mono.

The program we use to check specifications indicates the recording could also use a round of noise cleaning. After mixing the stereo to mono I didn't notice a great deal of noise.

When recording take a moment to sit quietly in your recording area and just listen. If you can hear it, so can the microphone.

Please upload the modified file and post another link to this same thread for a double check.

Hello Mikolaj,
Volume, noise cleaning and recording specifications are all on target.

The only issue is that the recording is still in stereo and we need mono. If you need help making the changes in GarageBand please post the question in the help forum. I'm sure someone there will be able to assist. viewforum.php?f=23

Once you make the change please post your revision in this same thread for another check.

Be well,

Hi folks,
I was trying to record my 1-minute test with GarageBand on MacOS, because Audacity is not working anymore on Catalina, as you mentioned.

After a long time spent trying several procedures, I managed to create an MP3 file which has passed the Status test in Checker; if you are interested in how to do it, here are the steps:

1) Record your file in GarageBand (I am using v10.3.4); the file will be recorded in stereo mode (if somebody has found a way to record in mono, please shout out loud)

2) From GarageBand menu, select "Share -> iTunes"; the file will be automatically shared on iTunes

3) From "iTunes" menu item, select "Preferences", then select "Files"

4) Select the "Import Settings" button

5) Select the format -> MP3

6) Select "Custom settings"

7) Frequency: 256 kbps / Sampling: 44100 kHz / Mono (WATCH OUT: I know that the desired frequency in LV is 128 kbps, but if you select 128 kbps the iTunes encoder will assign 64 kbps to the MP3 converter, therefore you have to select the double of 128 kbps, i.e. 256 kbps)

8) Press OK

9) Select the file that you have previously shared on iTunes, then select the menu "File -> Convert -> Create MP3 version"

If you now drag and drop the converted MP3 file into Checker, in the worst-case scenario you will get a warning about the volume, which you need to adjust somehow (either by re-recording your file or by using some other tool).
Don't forget to add the ID3 tags.

Hope it helps.
