There are many other effects available for your use. Also keep in mind this only works for noise that is repeated throughout the audio, one time background noises are much more difficult if not impossible to remove cleanly. Make sure to listen to any section you apply this to, and feel free to undo and try again if things don’t sound right. It is best to use as little as possible, since using Noise Reduction can add odd sound artifacts to your project. You can also adjust the amount of the reduction applied to your project using the sliders. Return to the Noise Reduction menu, the OK button should be active now. The menu will close, return to your waveform and highlight the portion of it (or all of it) that you want to remove noise from. In the Noise Reduction menu you should see a button labeled “Get Noise Profile”, click it to import your highlighted section. Once you highlight the noise-only section go to Effect > Noise Reduction. The larger the profile you give Audacity the better it can reduce the noise, but the sample doesn’t need to be super long. Find a section of your audio where only the background noise is audible, such as long pauses. First you must collect a “noise profile”. The Undo command can be used to try an effect then remove it, so feel free to experiment.Īnother useful effect is Noise Reduction, which is used to remove regular background noise and static.

Just remember to keep the waveform in the bounds of the window. You can also use the Amplify effect to increase or decrease the volume of any portion of the audio by highlighting that section of the waveform, going to Effect > Amplify, and adjusting the values up and down in the menu. Volume can be controlled for each track by using the sliders to the left of the waveform.
