Remove Background Noise from Video or Audio with Free Software

Remove Background Noise from Video or Audio with Free Software

What’s up guys, I’m Pete from the Gaming Careers YouTube channel, and we’re a channel dedicated to helping you grow your Twitch or YouTube Gaming channels so you can make a profession out of your gaming passion. Today we’re going to be talking about how you can remove background noise from your voiceovers. Now if you have background noise in your audio recordings already, because you live on a busy street where there’s a lot of car noise going past or maybe you have to have a fan on in your room or maybe just have a beast computer that has a really loud fan and you can always hear that in your audio recordings, today i’m going to be teaching you how with free software you can remove that background noise so you can just hear the crystal clear voice. Now you may be thinking that high-quality audio doesn’t really matter as long as your video looks good, but actually I find the opposite is true. If you go and have a look at your favorite streamers or YouTube channels I guarantee that they’ll probably have on par audio quality with their video quality if not higher. So what I’ll be covering in this video is I am going to turn on some of the fans that I have in my room, to create a kind of noisy environment and take an audio recording. Then I’m going to jump onto the computer and i’m going to show you in Audacity how I can remove that background noise, so it will be a live example as to how I’ve removed the noisy fans from my recording so you can do the same home. I’ve now turned the fans on so hopefully you can hear that there’s quite a lot of background noise going on. Not an ideal recording environment but something worthwhile for the tutorial so I’m just going to create quick voice clip that I’m going to use to then remove the background audio. “Hi I’m Pete from the Gaming Careers YouTube channel, why not subscribe?” Now before we jump into audacity and look at the noise reduction process, I would just give you 4 tips on how to record higher quality audio in general. The first one is try and remove as much noise as you can before even recording your audio. So if you can turn fans off or close windows, that’s really going to help because the less noise you have the less noise reduction you need to do. The second tip is all about the mic positioning from your face. I know a lot of YouTubers use the Blue Yeti or the Blue Snowball and you want to try and position that about 6 to 12 inches from your face. Not directly in front you don’t want to be speaking into it like this, you want to be about 6 to 12 inches away. My third tip would be to invest in a cheap pop filter. A pop filter basically just remove some of the pop noises that you create when you say your P’s and your T’s and removes them from the microphone, it acts as like a filter in between your mouth and the microphone. They’re really cheap, you can pick them up on amazon pretty cheaply or you can always just use a sock as it does just as good a job. Finally my fourth tip is to make sure that your audio levels within whichever program you’re recording your audio with are set correctly. If this is your camera settings or in something like Audacity, you want to be aiming for between -12 and -6 dB for when you’re recording your audio, then you can always boost this if you need to in post-production. Now the first thing that you’re going to want to do is download and install Audacity. I’ve put a link in the description below to take you to the website and there are versions for PC and for MAC so it doesn’t matter what operating system you’re running. The installation process is actually pretty basic so I’m not going to cover that here, just install it as you do with any other program. So the next thing we want to do is to open up our audio file that we’re going to be editing. You can of course use Audacity to record your voice overs and I’d recommend doing so, so if you’re just looking to record and then edit your audio afterwards then you just hit the record button, but I’m going to be opening up my example that I recorded earlier. The next thing we want to do is just to zoom in on the timeline so you can select the zoom tool here and try and find a point in the video where you weren’t talking and it’s just the background noise that’s occurring. Once you’ve found a section that has just background noise and none of your voice over the top, you want to select that section. Next go up to Effect, down to Noise Reduction and then a new window will pop up, you just want to click “Get Noise Profile”. What that’s going to do is it’s going to take the section that you just highlighted and set that as the noise profile. Now select all of the audio, you can do that by pressing “Ctrl+A”, go back up to Effect, Noise Reduction and then if you copy my settings here you can play around with these if it’s not quite removing all of the background audio but I find my settings are a pretty good starting point, and then you can just press “OK”. Now what this has done is it has taken the noise profile that you set and basically subtracted that from the full recording. It does lower the quality of your voice a tiny bit, but hopefully if you’ve set a good noise profile, this should be pretty negligible. Let’s now listen back to what it’s been able to do in terms of noise reduction. I’m pretty satisfied with that, so we’ll go ahead and export the audio, we just go up to File, Export Audio and save the file as a WAV. I would then go back into your editing suite of choice, for me that’s Premiere Pro and import the new .wav into your project and drag it down to a new timeline. As you can see it matches up perfectly because this is the exact same length, and then we can mute the original audio track which has the noisy background audio. And that is pretty much it, hopefully you guys have had good results with that and been able to reduce the noise in the background of your recordings or your voiceovers. If you’ve watched all the way to this point in the video and you’ve found the video helpful, please do give it a thumbs up. That really does help us out and also have a look around at the Gaming Careers YouTube channel where we started to really build up a good amount of videos helping you guys create better videos for YouTube and better live streams for Twitch, until next time guys, Peace!

  1. What about the gain? What should it be set at? You also mention DB levels for recording device. Where is that located in order to change it.

  2. Another STELLAR production!! I was beating my head against the desk to get my PC fan noise out of my recordings. THANK YOU!!!

  3. Hi, I have been watching all your videos and they are really helping a lot I must say .. Great job. In your video, I noticed that you're using adobe premiere but I don't really wanna start off buying a program. Do you have any free recommendations for video editing software? Also, I'm interested in creating gaming guides and stuff in the future but I'm not sure what program the other YouTubers are using to create the graphical images and movements and stuff. I'll use ClaicYuzolt as a reference. I love watching his ffbe guides and I would love to do something with ffbe and other games in the future but I'm not sure what I should use to go about starting out. I'm definitely going to pick up audacity, though. Thank you so much for any help you are able to offer. Personally I just love learning new things.

  4. is there a chance you know how to remove background noise in obs for streaming? Everytime i stream i can hear my fan, anyone in the room, and even the game audio from my astros! Also thanks for the videos man keep it up!

  7. You're an underrated channel, man. Your tutorials are easy to follow, and to the point. You've helped me immensely with getting my stream started!

  8. I've had a lot of issues in my stream cutting out or at least limiting the sounds from my mechanical keyboard. I could definitely invest in a cherry silent or ANYTHING quieter. I notice some popular streamers list their keyboard as a mechanical one, though I never hear it in their streams.

  9. Hi Pete! You're amazing, so easy to understand! My question, can we apply this noise reduction to OBS for streaming using Audacity? Please help! Happy subscriber.

  10. Is there any way to adjust the sensitivity while you are streaming? My stream can constantly hear my mouse clicks.

  11. Hi pete , thanks for such great tutorials . I was wondering if we can use this noise reduction for live streaming? if yes then how?
    thanks for making great content.

  12. I started watching the channel at 9am and it's now 8pm here in Australia. Excellent contents.Loved it. Keep up the good works. and if possible make some specific YouTube live stream tutorials and i'm still confused about the live voice input as I couldn't figure it out yet. Will be much appreciable if you can make a video on "How I can input the live voice with a background music and how to control the volume level"
    Thanks a lot

  13. do you remove background noise in the same way, if you record using the VB audio softwares which u recommended in another video. will it not effect the quality then. something like enhancing the audio quality in VB and then degrading using noise reduction in audacity

  14. I am sharing your vids with whoever I can brother. So helpful for me as a streamer that can walk people through every bit of set up except audio issues xD You rock man

  15. Is there a free software to compress or filter audio while recording/streaming? my voice is low and its hard for people to hear me but if I turn up my volume too high people just hear my fans

  16. This channel has become my go to when i'm having issues. I'm learning so much, thank you for putting these videos out, they're really helping someone like me, who isn't so knowledgeable on these things <3 Again thank you, happily subbed and sharing these videos constantly!

  17. Hi gaming careers i just wanted to ask how do you edit. Flv files fron obs to adobe premier pro. My obs just cant handle my loud air-condition and i wanted to cut some footage.

  18. keep up the good work man! your vids help a lot. thanks for skipping install instructions. if you cant properly install things on your own, you're probably not ready for the software alone lol

  19. Top notch tutorial my friend! Thanks so much for creating a channel like this. Definitely helps all the up and coming content creators!

  20. Will I be able to remove the sound of me pressing the buttons on my controller with this software? Since using this lowers the sound of my audio, how to I make a good sound profile, so it won’t be lowered so much?

  21. does this work for streamlabs obs? i have insane amount of background noise tried all the filters nothing works

  22. I have a question. Maybe some one can help. I want I just improve my audio so that when I play the mic doesn’t pic up back-round noise during game play. I’m not looking to be streamer. Just looking for my computer fan and clicks from my keyboard don’t bother the other player.??? Thanks guys in advance. Great video!

  23. Thanks for this. I have run my file through the noise reducer twice as it was still noisy (on the street) but now it sounds tinny. Any suggestions?

  24. Sorry if I sound a bit stupid – when I record video, I get a video file. How do I open that in Audacity, which I presume, works with audio file. And if there's an extraction method, how do I put back the worked on audio file in the original video and overwrite the existing audio?

  25. If I have a .MOV video file, and want to filter out background noise (cars driving by), how do I ensure that the file type is compatible with Audacity? The software is saying that it does not recognize the .MOV file type.

  26. Your audio sounds a bit… hollow though, like slightly tinny. It's not bad, better than shit background noise, but it's not perfect either. Probably better to just buy a better microphone and such. Good on a budget tho I suppose.

  27. it looks promising 🙂 I would recommend Woowave noise reduction app as well, works really good as well

  28. I hate when I'm doing a segment with a long sound but voice mod reduces the sound midway…. How do I stop Voicemod from doing this?

  29. I was hoping to find some noise reduction for live streaming. I noticed if I use discords noise reduction it sounds much more crisp but only way to have that work is I got be in test mode to have it play back in a way I can hear.
