How To Remove Background Noise In Audacity

hey guys and welcome back to another techguru video so today we are in audacity and I am going to be showing you guys how to remove background noise or unwanted background noise within your audacity audio files so I purposefully left a little silence there so we can kind of select what we need to select in the audio file and as you can see we're in audacity here on the screen and as you can see I'm recording audio right now as we speak now in order for us to remove background noise we got to select the noise that we want to remove so we have to select the unwanted noise so I'm gonna go ahead and stop the recording now and then if we go back over here in the timeline and we look right here we have a little blank area now I am in a studio where there are not that much background noise but let's just say there is a bunch of background noise right here now you want that background noise to be removed from within the whole project so not just this area here so what you're going to want to do is select the unwanted audio right here so select the unwanted noise right here and then go up to where you see effect and then go all the way down until you see noise reduction now under noise reduction you're going to see these two steps here now under step one you're going to see something that says get noise profile now that's going to be the button that we're going to want to press but before we do that we want to look at step two down here now noise reduction in decibels right here so if you want it to be reduced all the way go all the way down to zero if you want it to be you know all the way up that'll be a little louder whatever it may be so the less the further left you slide that slider the more of it will be reduced the further right you slide that slider the louder or more prominent that noise will be so normally you want to keep that right around six to twelve but remember if you go too low it's going to start removing some of the vocals that you don't want it to remove and because of that your audio is going to start sounding a little strange so leave that right around twelve I'm gonna go ahead and leave that back at 12 and in sensitivity leave it there at six and in frequency leave that at zero and then go ahead and click the get noise profile button now we have captured the noise profile which is this area here that we have selected alright and the next thing you're going to want to do is select the whole audio file so go ahead and hit command or control a on your keyboard or go up to edit and then go down to where you see select all okay so once we've selected all of our audio by doing that we then want to go back up to effect and then the first thing we're going to see is something that says repeat noise reduction go ahead and click on that repeat noise Road that will take that noise that you've selected and remove it to the degree that you've chosen to remove it and that way that background noise will no longer be in your audio so now if we play that audio back so I purposefully left a little silence there so we can kind of select as we can hear it's a nice crisp audio file that has no background noise getting in the way or interfering now if you have any questions on how to do this go ahead and put those in the comment box down below I'll help you out as much as I possibly can and as always guys don't forget to like and share this video and please please please subscribe to the channel for more great content just like this and I will see you guys in the next one
