Learn how to use ducking to make sure background music or sounds do not obscure a voiceover or main vocal.
- Ducking is an audio production technique used to automatically reduce the volume of one track in relation to the signal from another audio track. A common example of ducking is use in a radio commercial where the volume of the music bed is automatically reduced during the voiceover. That's more or less how we're going to use it here. So at the top of my library I have this BeneathShiftingForms project. I will tap that, and then tap the edit button in the lower left.
And I can see that I have two tracks. The track on the top is the music bed, and the track below that is the voiceover. So first let's just hear what this sounds like with no ducking whatsoever. I'll tap the back button a few times to get to the beginning and press play. (African music) - [Voiceover] The music track you're hearing in the background was made with two African thumb pianos - - All right, so you can hear those tracks are really competing.
The music bed is quite loud and the voiceover's not terribly loud. Of course, I could just turn down the volume of the music bed. With a paid upgrade, I could actually automate having that volume turned down as needed, but ducking makes it pretty much automatic. It's a really effective way to do this. So, let's look at the ducking control switcher actually in the track tools. So I'm going to tap the track tools button for the second track on the left.
And already this is set to duck. And I want to make this track the Duck King, and I'll tell you what that means. Basically the voiceover is going to be the signal that any other tracks that are ducked react to. So whenever my voice is talking, the music bed, if it is ducked, should become quieter. Or I can choose duck off, and then there will be no ducking action whatsoever.
But I'm going to go with Duck King for this track, and then I'll just tap on the empty area here to get rid of that. And then I will go up to the track tools button for the top track, and I see that that track is set for duck. So just like when someone yells duck and you get down lower, when this track receives the signal from the voiceover track, it will duck and get lower in volume.
And now I'm going to scroll down to the Ducking Settings, and I will tap that. And this will affect the ducking for all tracks and let's play and hear what's going on here. I'll tap back to get to the beginning. (African music) - [Voiceover] The music track you're hearing in the background was made with two African thumb pianos and a wooden tongue drum.
- So I just turned down the ducked level a little bit and I'm going to go back and listen one more time. This is the level that the ducked track should be reduced to in the presence of signal from the Duck King. (African music) - [Voiceover] The music track you're hearing in the background was made with two African thumb pianos and a wooden tongue - - All right so I just pressed stop. And you can hear a little bit of pumping. If you want to slow down the speed of the ducking, you can do that.
So I will tap and drag to the right on the speed control and you can see that that milliseconds display is going up so it actually is going to work more slowly as I turn the speed control up. I'll press the back button a few times and hear if that's any smoother. (African music) - [Voiceover] The music track you're hearing in the background was made with two African thumb pianos and a wooden tongue drum. - So you can hear it's a little bit smoother. It's a little bit more like I just turned down the volume and left it down.
Finally, on the left, the threshold control is the signal level that the Duck King, which in this case is the vocal track, must be below to be considered silent. So if I turned this threshold all the way up, basically, and went all the way back here to listen. (African music) - [Voiceover] The music track you're hearing in the background was made with - - Now there's no effect. So actually, where it was before, tapping and dragging the threshold control to the left, was better.
The threshold control is useful if the vocal track or whatever track is the Duck King has a lot of ambient noise, you might want to turn that threshold up a little bit just so that the music track isn't having it's volume reduced just because of a gust of wind or some sort of environmental noise. So that's a basic example of how you can use ducking in your audio projects. Next, we'll look at how you can use effects in your audio projects.
