- Ah, I love to relax in the garden
after a long day at work.
Hear how peaceful it sounds?
But what have I told you
I'm not telling you the whole truth.
What if the garden sounded like this?
(saw whirring)
It's amazing how the sounds we don't want
(siren wailing)
can easily be removed from our audio,
and in this video, I'll show you how to do it.
♪ Check the mic and make sure it sound right, boys ♪
♪ It sound right boy ♪
- So here we are in Adobe Premier Pro with my audio.
Now, there is so much we can do right here
in Adobe Premier Pro, but if you wanna really work
on noise reduction, sound removal, all that good stuff,
you really need to get over into Adobe Audition,
but there is a basic effect we can do,
and I'm gonna show it to you now.
So the original file with me talking here at the start
contains quite a lot of background noise already.
(wind blowing)
There, you can already hear it, lots going on there.
So what we need to do is change our workspace
up here in the top right and go from Editing,
as I am right now, to Audio over here.
This will give us a whole load of awesome effects
and stuff that we can put on each track,
and all I need to do is go into my Audio Track Mixer here,
top left, Show and Hide Effects, boom,
and we're on audio track one here
for the piece I'm working on right now.
We simply go into the first effect selection slot,
and we look for Noise Reduction Restoration,
and we add DeNoise to the whole track.
So that means anything on audio track one gets DeNoise,
and it's an excellent effect.
Let's show you how it works.
It's just a dial here from zero, so we've played at zero.
(wind blowing)
No change, and if we start fading it up as I play back,
you'll hear the noise just fades out.
(wind blowing fades)
Look at that, it's kinda like magic, isn't it?
It just faded the noise away there.
Obviously, at 100%, it's gonna affect my speech as well,
make it sound a bit robotic.
- Ah, I love to relax in the garden
after a long day at work.
- Although that's not too bad, switch it off.
- Hear how peaceful it sounds?
- And the noise is back, switch it up,
and the noise is fading away.
So we need to get a sweet spot.
I'd say probably around 35% is pretty good.
Let's set it around 35%.
- Ah, I love to relax in the garden
after a long day of work.
- And there it is-
- See how peaceful it sounds?
- And we can actually play back again,
and we can switch the effect
on and off to hear the difference.
- Ah, I love to relax in the garden
after a long day of work.
Hear how peaceful it sounds?
- That's it on, and this is it off.
So you can hear it's making a dramatic difference,
but we don't wanna stop there.
We've got other noises and effects
we really want to get rid of from this video.
So that's why I'm gonna push you over into Adobe Audition,
and if you're working with just one simple dialogue track,
simple even dialogue track, get it right, mate.
We'll go to the Edit menu,
and we'll look for the possibility
to edit in Adobe Audition.
Okay, we can edit the clip or the sequence.
In this case, it's all one single clip on audio track one.
So I'm just gonna say edit clip, boom.
It renders it out, and, wow,
there it is already here in Adobe Audition.
Now, this looks really confusing
so I'm just gonna switch off some of these settings
and show you how I get it to look all magical like that.
So usually, when you import a clip here into Adobe Audition,
you will get something that looks like that.
It's a waveform.
It represents how loud or quiet your audio is.
It also shows you, in between the speech,
there's a lot of noise 'cause you can see it
represented there when that should really be silent.
If there was no noise there,
it would look something like that, like a flat line, okay?
But we got noise that we're gonna fix.
So we need a few things available to us.
First is Spectral Frequency Display.
It's up here, up near the top left,
Show Spectral Frequency Display,
Shift and D to get it enabled.
Ooh, okay, we can see a whole bunch of stuff here.
We can see dialogue going on, but where there's no dialogue,
we can see this kind of faded kind of like,
you know, black, purple, red, yellow.
That, ideally, again, if we're working with silence,
and let's do this actually.
Let's go to Effects and Silence.
If it was silent, it would be black like that, okay?
So we're aiming to get somewhere near that.
Obviously, in a garden, we don't wanna
completely eliminate the noise because, well,
that wouldn't be good, would it?
It kind of detract from the sound,
and make it sound a little bit unnatural.
So we can work on that.
So I'll show you, first of all, in the effects track
what DeNoise is actually doing here in Spectral.
So you can see how Spectral Frequency works.
We'll go to Noise Reduction Restoration,
exactly the same effect as over in Premier, DeNoise.
Boom, and I'll set it exactly as it was, 35%.
You can't see any change,
but now, if I click in the top right,
this is the show Preview Editor option,
you can see, "Wow, that Spectral Display
has got a lot less colorful in between the speech."
So DeNoise already affecting it,
let's listen with it on, and then with it off,
(wind blowing)
much louder background noise there.
You'll even see the levels meters, they go down.
They're about minus 41 with it off.
They're up at minus 30, okay.
So that's dramatic amount of noise reduction already,
but we have other noises going on.
Let's start from the back
and work our way towards the start.
So first of all, we got a little bird tweeting here,
and now, this is why spectral is so good.
I'm gonna switch off preview for a moment
so we can see it nice and big.
There is our bird tweeting.
(birds tweeting repeatedly) - Video, video, video.
- Okay, just on the edge of my speech, it's tweeting away.
Well, over here, we've got a Spot Healing Brush tool.
The shortcut is B, and it only works in spectral,
and, basically, because I can see that bird tweeting,
I can paint it out like Photoshopping audio.
What I gotta do is just look for the bird tweet
and just paint it out.
See, it's kind of like content away fill.
Sometimes, you have to do one, two, or three passes
to really get rid of things.
So again, I can see that that's a sound,
and if you think this is just magic, what I'm doing here,
I can actually use this, the Paintbrush tool,
that's shortcut P, to actually paint,
and hold down Shift to paint multiple bits,
and I can listen just to make sure
that is the bird that I'm getting rid of.
(birds tweeting)
There it is, okay, we've isolated the bird,
but now, we're gonna use spot healing
to completely eliminate it or get rid of
as much of that bird tweeting as we can
'cause, obviously, it's less than optimal.
We don't want it there in our audio.
I'm going to make this a bit bigger
using the curly brackets.
You can increase the size of the paintbrush there.
Try and paint out every little bit of that bird.
Sometimes, it takes time.
Obviously, I'm gonna do it quite quickly
just so I can show you,
and sometimes, you'll get extra frequencies
up the top that you also need to paint over
to really eliminate the full sound.
- [Recording] And in this video-
- All that bird's gone. - Video.
- It's pretty much gone.
Now, I could sit here for another five minutes
and really eke the rest of that sound out,
but that's how spot healing works.
It's simple.
Now, you might have heard this police siren.
(siren wailing) - can easily be removed from-
- That's a lot tougher.
I can't just go ahead.
While I could try and paint it out like this,
you know, like I was doing the bird sound,
it would probably do a decent, hasn't really gone.
(siren wailing) - Can easily be-
- Still there, so we need to bring out bigger guns,
and for this, I'm gonna highlight
just one cycle of that police siren.
You can see it nice and clear there in Spectral,
and I'm gonna go to Effects, Noise Reduction Restoration.
We're gonna go for Sound Remover,
and then I'm going to set everything to Default.
So we're working with the default settings,
and I'm gonna learn the sound model
here of the police siren.
Look how it's already gone in the preview mode.
Now, if I select everything here
that contains the police siren,
let's move this out the way, and play back.
- [Recording] Can easily be removed from our audio-
- Oh, my goodness, that is amazing.
So with it off, it sounds like this.
(siren wailing) - Can easily be removed
from our audio-
- And with sound remover on, and, of course,
we've taught it the sound model.
- [Recording] Can easily be removed
from our audio, and in this-
- It's pretty much gone, hasn't it?
Do make sure enhanced for speech is ticked.
Sometimes, it's not.
If it's off, it'll make you sound like a robot
so I advise you tick that.
You can always increase the sound model complexity
a little bit.
- [Recording] Can easily be removed from our audio-
- And that'll remove even more,
and you might wanna just edge up the content complexity
in the refinement passes as well.
- [Recording] Can easily be removed from our audio-
- But that kind of brings it back in.
So you might wanna tweak with this.
It's kind of like doing, you know, chroma key
or, you know, green screen keying.
- [Recording] Can easily be removed from our audio-
- That's probably about right actually.
You want to just kind of get the right amount
so you're kind of green screened out your police siren,
but not got rid of the speech, so with it off.
(siren wailing) - Can easily be removed
from our audio- - With it on.
- [Recording] Can easily be removed from our audio-
- Obviously, there's some artifacting going on,
but remember, we've removed a siren from our audio
so that's pretty cool, and then we'll go over here,
again, something similar.
(saw whirring)
- [Recording] It's amazing how the-
- We got the the the handsaw or whatever it is,
the heads chopper, Effects, Noise Reduction.
We'll go for Noise Reduction process.
We'll go for default settings here.
Capture the noise print of just the handsaw, okay?
And we're trying to reduce that so we'll reduce it by lots.
Turn the DB level up.
Turn the noise reduction level up.
Okay, that's getting rid of it.
Let's look at preview.
Look at that.
Now, how's that working on the speech?
Is it decreasing the volume of the speech?
- [Recording] It's amazing how the sounds we don't want.
- It's done pretty well, but I can still hear
that hand tool still there, so I'm just gonna say,
we'll work on these frequencies.
I can see the frequencies in the low end,
1K, 2K, 3K, 4K around here so I'm increasing
the Noise Reduction effect on those frequencies.
- [Recording] It's amazing how the sounds we don't want.
- And remember, with it off.
(saw whirring) - It's amazing how the sounds
we don't want. - And with it on.
- [Recording] It's amazing how the sounds we don't want.
- I might sound a little unnatural so I might back off
the Noise Reduction percentage a bit.
- [Recording] It's amazing how the sounds we don't want.
- And even the Reduced By a little bit, too.
- [Recording] It's amazing how the sounds we don't want.
- So we kind of got rid of that hand tool.
That also sounds a bit like a pneumatic drill.
So you can do basic at things like that.
You can, again, go ahead and apply it,
and we've already painted out so many sounds.
So remember, we painted out the parrot.
We sound removed the police siren.
We noise reduced the hand tool.
We used a bit of DeNoise over the whole track,
and, of course, don't forget.
- [Recording] What if the garden sounded like-
- Right there, we got a bit of wind rumble,
and that, as you can see, if we go to the preview mode here,
is happening right down here in the low end,
and now, a number of ways to do this,
but one of the easiest, easiest ways of doing it
is simply by going in and looking for filter and EQ
in your Effects rack.
You can also do this over in Premier,
and you can bring in a Parametric Equalizer.
Default settings, switch on HP, High Pass Filter,
and whack this up.
Now, up at the top, you will see, if we go to Preview here,
yes, it's eliminated the wind,
but it's probably eliminated frequencies from my voice.
(robotic indistinct talking)
- So not so great.
Let's bring that down, bring the wind back in.
- [Recording] What if the garden sounded-
- And then let's bring it up.
- [Recording] What if the garden sounded-
- And a bit more.
- [Recording] What if the garden sounded-
- And you can see that it's starting
to erase some of that wind.
- [Recording] What if the garden sounded-
- It's also thinning out my voice.
So you kind of have to get this into a sweet spot.
- [Recording] What if the garden sounded-
- So you've got some of the wind out.
Let's listen to it before.
- [Recording] What if the garden sounded-
- That's a lot of overpowering winds.
With the High Pass Filter.
- [Recording] What if the garden sounded-
- Most of the wind's gone.
That's got us most of the way.
Then we can go ahead, and, of course,
we can spot heal again.
What I'll do is I'll grab a big fat brush here,
make it really big, maybe not too big.
I don't wanna paint out too many of my speaking frequencies.
This is gonna kind of work down here on the low end,
just paint that out as much as we can,
and that will start to, as you can see down here,
in the Preview mode, and I'll remove a lot of that wind.
- [Subtly Robotic Recording] What if the garden sounded-
- Now, obviously, it's artifacted of my voice a little bit,
so maybe don't be so aggressive on that.
Wind is a troublesome thing.
I would advise using High Pass Filter
and a bit of spot healing, but if you really can't do it,
remember, it's always good to get the best audio at source,
and while the tips I've given you in this video will work,
do try and record with the best quality microphone you can.
A lavalier mic is always good.
A shotgun or directional mic, so you're not picking up
too much background noise, always advise.
If there's lots going on, use a handheld dynamic microphone
or something like that, and, of course, for wind noise,
please, please, please, please, please
use like a little wind sock over your boom arm or whatever
or I think some people call it a dead cat or a cat dead.
I just don't know.
If you know the real name, let me know in the comments.
I think everyone calls it something different, right?
Anyway, that is how you remove any background noise
from your video, from your audio.
