How to Remove Background Noise in Audacity | Quick Fix!

Background noise can creep into your audio recordings unnoticed. From air conditioning units, computer fans to noisy neighbours! We definitely do not want to keep those in our recordings and the good news is – we don’t have to! In this blog, I’ll show you a quick way for how to remove background noise in Audacity. It requires minimal audio editing knowledge and in a matter of seconds (yes seconds!) you can dramatically improve the quality of your audio recordings.

Removing Background Noise

To start with, use the Noise Reduction effect. Select only the noise you want to eliminate. This point is important as this method will not work if you do not select the audio here correctly (no speech or breaths). Simply go to Effect > Noise Reduction and click Get Noise Profile.

Next, select everything by double-clicking on your audio (or CTRL / CMD + A). go back into Effect > Noise Reduction, then push the Noise reduction up to around 30 dB, move the Sensitivity up to around 9.00, and reduce the Frequency smoothing to around 1 (the higher this is, the harder it works and the thinner the voice becomes).
