Hello everybody, welcome back to my channel, Jennifer Marie VO, where I teach you different
ways that you can make money online working from home.
In the past few months I've released several different tutorials teaching you how to become
a work from home Freelancer on websites like Upwork or Fiverr.
And in order to sell your services on a website like Fiverr, or Upwork, you need to have certain
skills that you can offer people.
And one of these skills is how to remove background noise in audio or video.
I can't tell you how many times I'm watching a video online and hear static or fan noises
or hum noises in both audio and video.
But a lot of people just don't know how to improve their audio quality.
And I'm going to teach you how to do that in this video.
So learning to remove background noise and static from an audio or video file is a very
useful skill to have.
You can use this skill to edit your own videos, your personal videos, your home videos, or
even professional videos for work.
You can edit your own YouTube videos using this skill.
You can edit podcasts, lectures, or sermons, or even edit transcription files to make them
easier to understand.
Or you can sell this skill as a service on freelancing websites like Fiverr or Upwork,
charging a flat fee or a certain fixed price to remove all the background noise and improve
the audio quality of a client's video or audio file.
So in this video, I'm going to walk you through step by step what you need to do.
Step one, we're going to download and install audacity, which is a free audio editor software.
Step two, we're going to download and install the FFmpeg Import Export library to be able
to import video files into Audacity.
So this step is important if you want to edit video files, the audio quality of video files.
Step three, we're going to import or open the audio file or video file into audacity,
then remove the background noise and static and clean up and amplify the audio and then
export the new audio file.
Steps two and four in yellow only apply if you want to remove the background noise from
a video file.
And step four, we're going to open the video file in a video editor.
This could be Filmora, which I like to use or VSDC, which is a free software.
And then separate or split the original audio from the video and delete the original audio,
then import the new cleaned up audio file and match it to the video and then export
the video file with the new and improved audio.
I know this sounds like a lot of steps.
But it's really simple.
And I'm going to walk you through exactly what you need to do step by step.
Before we get started, if you haven't already, make sure to subscribe to my channel for more
videos just like this one.
Not only do I make videos teaching you how to make money online, I also like to teach
you the skills that you need in order to succeed online.
So let's get started.
Okay, so step one is that we're going to download Audacity.
So you're going to go to audacity team.org.
And then you're going to click on download, and you can choose Windows or Mac, I'm going
to choose windows, then your download should start automatically.
If not, you can use this direct link by clicking left clicking here.
And then once it downloads, just double click to install.
Then you're just going to go through you can choose your setup language, choose next next,
and just install it into the automatic folder that they're telling you to install it to
and then install and click Next.
And finish.
So then when you go ahead and open up audacity, it will look like this.
So if you're only interested in cleaning up the audio of an audio file and not a video
file, you can just go ahead and skip to the next part of this tutorial.
But if you want the option to clean up audio and video, then you're going to need to proceed
to the next step.
So right now to open up an audio file, you can go File Open or file import.
And you can see here I opened up an audio file and it opened without any problems so
I can go ahead and make any edits.
But if you want to open up a video file right now, and click File Open and open up a video
file to edit the audio of a video file.
You can see here there's an error importing.
It says without the optional FFmpeg library audacity cannot open this file type.
So we're going to need to install that and download that library and I'm going to show
you exactly how to do it I undid installed everything on my computer in order to show
you how to do this because a lot of tutorials don't show you exactly how to install that
library.
So now at the top, click Edit, then go to preferences.
And then click on libraries.
And you can see here it says FFmpeg library not found.
So we're going to click on the download button.
And that will get us to this page here.
Now, because of software patents, audacity cannot include the FFmpeg software or distributed
from its own website, so you have to install it from the external website.
So you're going to click here on FFmpeg installation section under Windows or Mac, depending on
which one you're want to install it on your Windows or Mac computer.
then here you have some instructions.
And you're going to click under for full instructions, see installing FFmpeg for Windows.
And then here, they're going to give you a link to the installer page, you're going to
click on Go to the external FFmpeg download page.
So click that button, I'm just going to open it in a new tab.
And then here, it's very important, you want to download the FFmpeg 2.2 binary for Windows.
So that's the one you want to there's a lot of links here.
So just click on the FFmpeg 2.2 point two.
And that will open up a file you can see down here.
So wait till it downloads and then click on it or double click on it to install.
Go ahead Select your language.
And just keep pressing next until you have installed it on your computer.
I wouldn't recommend changing any of the settings just keep going and install it where they
are telling you to install it.
And now click Finish to exit the setup.
Now very important, you're going to want to if you have audacity, open close audacity,
and then reopen audacity, okay, so you have to close it and reopen it.
Then if we now go to edit and preferences and go back to libraries, you'll see here
that we have the library installed.
If for some reason it's not installed there and you can't see those numbers, then you
can click locate and find it on your computer.
But it should be automatic if you just left all the settings as default.
Okay, so now I'm going to open a video file just to show you that it works.
You go File Open and you can choose whatever video file that you want to edit the audio
and then you can see it is importing.
And now we're ready to edit this audio.
Okay, so first, I'm going to show you how to remove the background noise from an audio
file.
So again, file open or file import audio, click on the file that you want to remove
the background noise from double click or press open.
So what we first need to do is find a sample of the background noise that we want to remove.
So always start at the beginning or the end.
To find your first sample, click and drag your mouse and then release.
And that highlights this sample here.
So if we press play, you can see all this movement here this green, and that showing
us that we have this background noise that we meet, we need to remove.
So keep it highlighted, then go effect noise reduction, get noise profile.
And that is going to tell audacity that we want to remove this sound from the entire
file.
So now we need to highlight the entire file.
And to do that you can go select all or press Ctrl plus a on your keyboard.
Now again, go to Effect noise reduction.
Okay.
And now if we press this sample again at the beginning, it's much lower.
Okay.
We can even do it again if you wanted control, effect noise reduction, get noise profile
control plus a on your keyboard effect noise reduction.
Okay.
And now let's press play.
And you can see nothing is happening here.
This is a test file to say.
So now sometimes people might export it like that and assume that the background noise
has been removed from the entire file.
But sometimes for for me for example, my fan of my laptop will kick on after a while and
I'll remove the background noise and not realize that I had more background noise I needed
to remove in the middle of the audio.
So make sure to listen to the entire audio file or video file and find out if there's
more background noise because for example for you press play on this.
This is a test file to show you how We can remove background noise from a file.
Both when there's high levels of background noise, there's more background noise here
that we didn't even realize.
So this here, we press play.
This is background noise, we want to get rid of a fan kicked on.
So we're going to keep highlight the new background noise, we want to remove effect, noise reduction,
get noise profile, again, Ctrl plus A to select the whole file effect, noise reduction.
Okay, and you can see it's just cleaned that up throughout the entire file.
Both when there's high levels of background noise and lower, and you can go ahead and
try to remove even more background noise you want
both when there's high levels of background, okay, and then when you're finished, you can
press Ctrl plus a again, and go effect and go amplify and even choose to amplify this
or make it a little bit louder if you want.
I like to go minus three DB or minus four, and then Okay.
And then your audio is even louder.
And then to export we go File Export.
And you can choose Export as mp3 or WAV, or export selected audio if you just want to
export a section of it.
sample file to audio edited and then press save.
Okay, and then it will export your file and now you have a cleaned up audio file.
So finally, I'm going to show you how to clean up the audio from a video file.
Again, file open or file import, select the video that you want to improve the audio quality
of.
So let's listen to this.
I'm Jennifer from sparkle English and recently I have Okay, so at the beginning here, we
have all this background noise that we want to remove.
Now this one you can see there's two tracks, that's because it's stereo, but it's still
the same process, just click and drag to select the sample.
Again effect noise reduction, get noise profile Ctrl A to select all effect noise reduction.
Okay.
And as you can see there, it's just cleaned up the audio really nice, it can even amplify
the audio control a effect, amplify.
amplify it a little bit.
Let's just do this one more time with the noise profile.
effect noise reduction, get noise profile Ctrl A. Okay, check through the whole file
to make sure there's no other background noise.
This is a short clip.
So I know there's not file export, export as mp3 or WAV.
Now make sure when you're doing this not to cut any pieces out of this audio because especially
if it's a video where someone's talking, you don't want to remove any audio because you
want it still to sync with the mouth.
So let's go save.
Okay, so now I'm going to show you how to merge the video file and the new improved
audio file, we're going to use Filmora.
Now I use Filmora.
For my video editing, you can get Filmora by going to the link in the description below.
Filmora is a paid software which is very affordable, but I will show you how to do this method
using vsdc which is a free video editor afterwards.
So what you'll do is you'll click here you'll import both your video and audio files.
Then first we're going to take the video file and bring it down here onto the track.
I'm just going to put match to media.
Now let's play the beginning of the file so you can hear the static.
"I'm Jennifer from Sparkle English."
And what we're going to do is we need to remove this audio right here.
So we're going to right click and you can either choose mute to mute the original audio
or detach audio I'm going to choose detach audio.
So now that has brought our original audio onto a separate audio track.
Now within Filmora you can remove background noise but I prefer to remove background noise
with audacity and then import it in because I just think it does a better job in Audacity.
So then you're going to click on this file here and choose Delete.
And now we just have the video file by itself.
So now what we want to do is add the new improved audio file which we have imported here.
And now all we have to do is drag it down here onto the audio track, you can click here
to expand the timeline.
Now the most important thing is just make sure it lines up.
Because we want it to be synced perfectly.
If we haven't over here, it won't be synced up so just make sure it is at the very beginning.
So it lines up perfectly.
And then let's press play.
And we can hear the difference between the original file and the new and improved file.
"I'm Jennifer from sparkle English and recently I have the....
I'm Jennifer from sparkle English and
recently I had the opportunity to work with Sarah."
Okay, and now to export this will click Export, create video.
And then you can just choose the type of video so I like mp4 and go ahead and sample video,
audio edited and then export.
And then once this is finished export and you'll have a file with cleaned up audio.
Okay, so now I'm going to show you how to do this with vs DC which is a free video editor.
I have the free edition here.
You can see it's a little bit more complicated.
There's lots of options here.
But it's it's still easy to do.
So we're just going to choose blank project under start project now.
And then here, we're going to choose Add object and go to Video and locate the video.
Press OK.
And now we have layer one and we have our original video here.
And now what you want to do is click on layer one, which is our video and it has audio that
we need to remove.
Now to remove the audio is a bit more difficult than with Filmora.
But what we'll do is we'll go to editor, click audio effects.
Under amplitude, click silence.
Then click OK.
And basically that's going to put a silence layer over the entire clip.
So when we press play, it's completely silenced now, so now we need to add our good audio
and sync it to this video.
So we're going to go add object audio, choose your new and improved audio.
Press OK.
And then that might automatically add to the layer so we're going to drag it so it lines
up with our original layer so you can see here if we click and drag it on the timeline,
it will snap to the bar and it will begin and end at the same time as our file so we
can press play.
I'm Jennifer from sparkle English and recently I have Okay, and now we'll go export project.
And you can choose you know if you want to export it, I'm going to choose web and then
to mp4 and then choose Export project.
It says here that we use premium features for our project, but this is fine it will
still export even though if we don't upgrade to the pro version.
It'll still export without a watermark so just choose continue.
