I used to get that white noise on Audacity recordings. I also got it on other recorders as well. I’m a singer/songwriter and record myself.
I have totally solved the problem with my Audacity recordings. The solution is very easy.
Here’s how I do it:
1 - I make the recording (the white noise can be heard at the beginning and end where the music is not playing, and also in very quiet spots anywhere in the recording).
2 - After the Audacity recording is made, click on the recording and highlight the start of the recording before the music starts (the part where all you hear is white noise only).
3 - Then at the top of the Audacity recording page, click on “effect”. Then click on “noise reduction”.
4 - A sign then comes up, then click on “get noise profile” in the sign. The sign will then disappear.
5 - Next, you then highlight the “entire” recording from beginning to end.
6- Then you go back to the top of the Audacity page to “effect” again, and click on it. Then click on “noise reduction” again.
7 - A sign then comes up (the same sign as before). Within the sign you will need to adjust the settings. Here are the settings I use: Noise reduction 10: Sensitivity 5.00: Frequency smoothing 0: Noise “reduce”.
8 - Then click on “OK”.
That’s it. Whenever I do that procedure the white noise disappears from my recordings.
