As we're going to the sequence, editing and enhancing the audio, there may be some clips with some basic audio problems that we want to fix, like unwanted background noise, or hum. We have some ways to really dig in and fix this adjusting Audio EQ, which we'll look at in the next movie. But there are also some automatic functions for fixing basic audio problems. Let's take a look. So I'm going to go into 6.3, and when we import footage for the first time, one of the options is to analyze and fix audio.
Let me just bring up the Import dialog box to remain you of this option, I'm just going to Import Media, and I'm just going to pretend to bring this in, import selected, this box right here, Analyze and fix audio problems. If you check this box, then Final Cut is going to go through the footage and determine whether or not there are any underling audio issues and then potentially it will offer some solutions to eliminate those issues. These auto fix issues include loudness, which improves the main audio signal to make it more uniform; background noise removal, which reduces background noise; and hum removal, which reduces common electrical hum noise at either 50 or 60 Hz. So I'm going to Cancel here.
If you did not perform this analysis on import, you can always do it after as well. All you need to do is right-click on a clip or all clips, Command+A, and then right-click and choose Analyze and Fix, and then you can select this option, Analyze and fix audio problems. If you're following along with exercise files, then this has already been done, so I am going to Cancel. How do we determine if there are problems? Well, all I'm going to do is either click on the clip in the Event Library or click on the clip in the Timeline and then open the Inspector, Command+4 and then right here, Audio Analysis, it's going to tell me if there were problems detected, then if I click on this arrow, it opens up the Audio Enhancements window.
By the way, if you don't go to the Inspector, you can just open up the Audio Enhancements window by going to Window and then go to Audio Enhancements, or Command+8. So when you take a look at the Audio Enhancements window, it shows you what's recommended as a fix. If there's a green check mark, that means Final Cut did not detect a significant problem with the audio. If there's a red exclamation mark, then that means Final Cut deemed the problem to be severe. And if there is a yellow warning sign, that means that potential audio issue has been flagged.
All you need to do to enable the fix is to click on this button here, and Final Cut will apply a basic fix, it's as easy as that. Again, you can do this to clips in the timeline or to clips within the Event Library. Now I don't really care so much about the problems that exist in my B-roll because I have lowered the volume so much. I care more about my interviews. So I'm just going to click on each one of these and see if there were any problems detected, and as you can see, it didn't find any with BD or Justin or Owen or John Downey.
We already know there are quite a few problems with our interview clips. So I just want to show you that even though a problem was not detected, that doesn't mean that enabling one of these quick fix options won't improve your audio. For example, let's come down here to John Downey. We already know that there are some significant issues with this interview audio, let's go ahead and just check it out. I am going to press Shift+Question Mark. (John Downey: It's a much better product, it really is.) I'm going to enable the background noise removal, and let's check it out again, so I'll do Shift+Question Mark.
(John Downey: It's a much better product, it really is.) And then again without it. (John Downey: --it really is.) So, as you can see, it does improve it significantly. I'm going to play around again and then increase background noise removal so that I can show you that you need to be careful about how much of this you apply. And I think I'll decrease my pre- and post-roll real quick. Right now it's not on, I'm going to play loop, and let's apply the background noise removal. (John Downey: It's a much better product, it really is. It's a much better product, it really is.
It's a much better product, it really is. It's a much better product, it really is.) So, as you can see, you need to be careful of bringing the amount up too much because it can start to sound like the person is in a tunnel or under water. But it can offer some significant improvement. Same thing with Justin, if I come over here Shift+Question Mark, and I'll apply background noise removal and see if that improves it. (Justin: --all these farms, that's for sure. This is where the magic-- --all these farms, that's for sure. This is where the magic-- --all these farms, that's for sure. This is where the magic-- --all these farms, that's for sure. This is where the magic-- --all these farms, that's for sure.) So, as you can see, that did help, but it sort of sounds like he's on a telephone, so we'll probably need to apply some other fixes.
But both background noise removal and hum removal can be really helpful in this regard. So, as you can see, these basic audio fixes can improve your audio in certain circumstances. If you need additional control in fixing and enhancing your audio, you may want to explore EQ adjustments and audio filters, both of which we will cover a little later in the course. For now, though, make sure you always take a look to see how Final Cut recommends you perform these basic fixes, as it can really make a difference.
