Hi there, this video is all about normalizing or balancing your audio. What does it mean? It just means, we just want to get the loudness of your voice, that you've got in your tutorials to be consistent across your whole course, and be consistent with the world. You've probably come across this, you're watching a YouTube video, and it's just really quiet compared to the last video you watched. They're not quite balanced. So that's what we need to do here, just add some consistency so that people don't complain, like, "I can't even hear, it's not loud enough." And you're like, "Just turn the volume up." But there's a kind of like a median level that the internet should be at. They'll call it either normalizing or balancing the audio. So those are the terms that you can use. 

I'm going to show you just the software that I am comfortable using, and how to balance it. I don't know every single one, so I'm just going to show you the ones that I know. But if you're using some other editing software, ScreenFlow, that I haven't mentioned, or say using Windows Movie Maker, it's not something I have much of experience in. And I don't have it on this computer. Just go to YouTube and say, "how to balance or normalize audio using”, and type in your editing product. And I'll show you just the basics of, I'll do Premiere Pro because I know that well, Camtasia, because I know that well, and I'll do iMovie, I have no idea really how to use that, but it's on my machine, and I've had a little look for you, and I'll just give you the one sort of quick version. 

Let's jump into the computer, and I'll show you how to balance your audio. So this is going to be a quick demo, especially iMovie. I'll start with this one, because it's the free one, it's on a Mac only. It's not going to comprehensive, mainly because I don't use iMovie a lot. And this version of iMovie changes depending on which computer you have. So I'm just going to give you a quick kind of, a rough, so that you can get an idea of how you might do it with your project. So I'm going to 'Create New' movie. I'm going to add some content, which one? I'll add one of the videos that I've recorded for this course. I'm going to drag it into the timeline. And all the versions are up the top here, I know, but what you're looking for is, see there's like a little bar down the bottom here. Blue one in my case, I've seen it being green in older versions. You want, basically the little peaks, to be not too far over that line. 

So if it's down here, watch this, I'm going to grab the line that runs through the middle. Can you see, you can lower it, or higher it, so there's way too loud. If it crosses the top there, it's going to be, they're going to kind of, what's called clipping, it's going to clip some of the sound out. Say you're editing with Camtasia, it's just way too loud. So you want it to be, where? Out there. So you don't want too many of the little peaks to peak over the line. You want to be close to the top, but nothing touching the top. And that kind of, it's very visual in iMovie, it's not very scientific. 

There are fancier ways of doing an iMovie, and I just don't know how to do them, but that's the basics, right? You're looking for this waveform here to be not too close to the top. Let's jump into Camtasia for Mac, that I know a lot more. So I've brought in something that I've recorded for this course. I'm more likely to use it. So how do I know this one's okay? It's the same sort of principle. They don't have a really scientific way of doing sound here in Camtasia. Either you're using this full width here of this bar, to be-- that's too high, and down here is too low. So what you can do is click on it, and you'll hopefully get the same sort of line like iMovie. 

Watch this, if I can yank it up high, that's way too high, and down here is too low, so if you recorded it, and it's nice, it's really low down here, you just got to pull it until, where? Till, see these peaks here, none of these peaks should appear over the top there. So you're just looking for something like this. Now that's for one clip. If you end up getting to a point where you need to trim it, and you've got, you know, you've edited a lot, and there's lots of different ones, you might have to go through and just kind of edit that one. Go through. You've got this piece here, you wanted to be this, a bit quieter. So you'll end up having to manually go through, and raise them, and lower them. It might be a chance where actually, say it's really low, it starts off really low, there's only a certain amount of drag you can do. 

You get to a point where it just won't let you get any higher. Say you do need to get higher, you can go to 'View', and go to 'Show Properties'. And click on this audio icon here. With this selected you can actually just drag it, watch this. Can you see, it's adjusting over here, but you get more scope to go up and down. Don't have to, just use that line. So Camtasia is very visual in terms of its editing. Let's look at the slightly more professional tool, Premiere Pro. 

So I've brought in a track here, I'm going to add it to my sequence. And the same sort of thing here, except I get to make this a lot bigger. So can you see-- I'll drag it back over. Where are you? Here you are. Over here, see this little line, so this is your video, this is your audio. I can make the audio a lot bigger so that makes a little easier to see. Now mine is looking pretty good, same sort of rules here. The top of it is way too high, and the bottom of it is way too low. So somewhere kind of in this top two-thirds is perfect. But what you can do in here, is a little bit more scientific. Let's say that I've got this one, but I'm going to bring in a different track. Let's bring in this one. So I'm going to drag it onto my timeline. So that's two of them, and let's say-- they're pretty close in terms of their sound. But let's say this one is just a lot lower than this first one here. 

There's a couple of things you can do. You can drag the center line, just like the other programs, to make it louder or quieter. Doesn't go up and down though. Can you see, these little peaks and valleys, don't go up and down like the other two programs. It does raise it. And what you're looking for is this thing; this is called your audio meters. It just shows you, actually with a bit more science, the actual decibel level of the audio. And what you're looking for, any kind of spoken word tutorial. You're looking for the decibels to be between, this -6 and -12. Don't ask why it's in minus. But I'm going to preview. "Pretty much all the software… You can see… “Allows you to do that kind of real basic stuff. There's me talking. "…you animate it as well." You can see, "…and if you want to go beyond that… I'd say, it's pretty good, right? It's bouncing in between here and here, and it's perfect. 

You're not going to be that, yours is probably going to be a lot lower, probably, or maybe just a bit too high. I'm pretty practiced at recording it at a really good level. Let's say I want to raise it and lower it down. I just drag this line, and hit 'space bar'. "Like what I've got… You see, he's bouncing around down here between 18 and… - "If you're going to do it… So it's too low. So you want to kind of raise it up, until you get to a point where… "…yourself, like I do."  It's bouncing in here. That will just mean, it's going to sound equivalent to everything else on the internet. 

So you can do it manually by dragging these things here. You can get a little bit more fancy, and select-- say you've got lots of different, you've recorded from different cameras. So there's very different audio levels. You can grab them. And I'm going to turn the levels back to here, or the adjustments here. I'm going to select both of these, and there's a cool thing in the new version of Premiere Pro. If we go to 'Window', and go to, you're looking for 'Essential Sound', it's got a handy trick in here. So I've selected both of these. Or let's say you've got only 30 clips. You've edited it out from 100, just select them all by dragging across them all. Go into 'Essential Sound', and you're looking for this dialog box, click on that. Click on 'Audio Match'. Keep an eye on these, watch, can you say, they're all adjusted. 

So it's trying to do an average, trying average to a kind of an international standard. You will notice that it should bounce down between…  "…you need some reasonable… -6 and -12. If you can't see the numbers here, watch this, I can just grab the little line in between them. It's a bit annoying that it disappears, just because it's too small, it gets rid of them. So hopefully bouncing in between. ?? 

Again, I try not to-- I guess this wasn't like a full hard core tutorial. It was-- I didn't want to just leave you with no understanding of how you might do it in your software program. So remember the term is, normalizing or balancing audio, and just type in that into YouTube, “how to balance audio using iMovie or Windows Movie Maker”. And hopefully you'll be able to work out how to kind of get your audio in some sort of reasonable order. So that's going to be it for getting your audio ready. Let's get into the next tutorial.
