Here you can see the before and after tracks Important Note: Reducing too much noise may often leave your recording sounding really bad it tends to sound very thin and tinny if you take it too far. Now, hopefully, Audacity will have removed the background noise. You can choose how much noise you want to filter out manually with the “Noise Reduction”, “Sensitivity” and “Frequency Smoothing” controls. Here you can Preview the effect and check if it’s working properly. Select the track by clicking on the far left side of it, go back to Effects, click on Noise Reduction again and click “ OK”.

Now that Audacity has created the noise profile, it’s time to instruct it to remove it from that specific track Use the newly created Noise profile to remove the Unwanted Noise This will create a noise profile which will later be cancelled out. Once you did this make sure to click on “ Get Noise Profile”. Select the part where you are capturing most of the ambient noise, which in this case is at the beginning of the recording.Īfter this go to “ Effects” and click on “ Noise Reduction” If you don’t give it enough time to create the noise profile efficiently, it won’t be able to remove it as effectively. You want to create a background noise profile that the software can recognize and then remove. If you didn’t record yet, but you know that there will be background noise, then let it record just the background noise for 10 seconds Don’t talk, sing, perform, etc. If you already have an audio/video recording that you want to de-noise, look for a section of the audio where you can only hear the background noise for 5-10 seconds and where there is no important audio, such as someone talking, music, etc.
