Removing audio noise with Audacity
In this blog post we will show you how to remove background noise from your audio using Audacity. Using the noise removal tool in Audacity is a two-step process.
First highlight a section of audio where nothing was deliberately recorded. A good place to find this is at the beginning or end of your recording.
Once you have an area selected, go to be Effects menu and select noise removal.
From here simply click ‘Get noise profile’. That is the first step.
The second step is to use that noise profile to remove the noise from your entire audio file.
To do this select and highlight the entire audio recording.
As before go to the effects menu and select noise removal.
This time you will simply click OK to remove the noise and that is how easy it is to remove background noise from your audio file in Audacity.
