Noise Removal is not working [SOLVED]

I am recording an audio book and the Noise Reduction is not doing anything. I have used Audacity for several years with a Mac. This is my first time using it on Windows (Windows 10).

Regardless, It should all be the same.

The recording is just myself talking in an isolated area. So the background noise is nothing that would override the vocals.

I am getting the Noise Profile of the selected background noise, then applying it to the area I want to remove it, and nothing at all is changing.

Any reasons why this is not working???


Probably you are expecting the default settings will just work when you need to change them.

What version of Audacity are you using? Please see the pink panel at the top of the page. Audacity 2.1.0 and later have Noise Reduction not Noise Removal. If you are using Noise Reduction, try increasing Sensitivity. If you hear artifacts in the noise-reduced audio, try Frequency Smoothing of 3.

If you need more help, please export and attach a sample in WAV, up to 10 seconds, noise-only followed by desired-audio-with-noise. Give us the sample before you applied effects to it. Please see here for how to attach files:


Thank You for the help. Changing the Frequency Smoothing to 3 did the trick.

Now it’s smooth sailing ahead

Thanks for the feedback and glad you got it sorted.

You might be glad to know that we changed the default settings for the upcoming 2.1.2 release to: 12, 6, 3

I’ll lock this thread now.
