- 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. If you've got any questions, do let me know in the comments down below. If you've not done so already, check out musicradiocreative.com. This is where my team of
