Hello, all! I hope you are doing well. I would love some feedback on this audio. I realize you can hear a bit of someone playing duolingo in the back, but I wasn't sure how to remove that without distorting the audio. In the future, I'll try to record in a distraction free place! Also, I think I have a little bit of annoying popping going on. Please let me know if you have any tips on how to improve! I used audacity on Mac OS and I am using a USB headset. I look forward to hearing back from y'all! :D

Hi. Welcome to LibriVox.

You are almost there. A couple of suggestions to improve future recordings -

I would recommend you apply a noise reduction to tone down the background hiss.

Two passes using the default settings seemed to work well.

The volume, while technically within the 86-92 db range is close to the top so I would recommend deamplifying by about -2 db.

If you would like you can try the above and resubmit a new test or you can take this into consideration with your next recording. If you decide to do another test, just post the link to this same thread.

Thank you so much for your feedback! I ran noise reduction twice (with all the sliders at 6) and amplified it by -2 dB!

Hmm. Is this the same file or did you rerecord? The volume on this is much lower than the last one and at 79.8 needs to be amplified by about 10 db.

On the positive side, the background is now good.


To judge whether you have the volume set correctly, your waveform in Audacity should look similar to this example:

Detailed instructions for adjusting your input levels can be found here:

You can download the checker program to check your volume after exporting to mp3 and before you upload your file.

If you prefer you can use the Replay Gain plugin in directly in Audacity to tell you how much your file needs to be amplified to get to 89 db. Instructions here:

One more try?
