Putting one of these audio transitions in your timeline will definitely ramp up the suspense.
So—you've got a scene—a suspenseful scene. The tension is high, so high you can cut the tension with a spork. What do you do? Well, one thing you could do is throw an audio swell transition down into your timeline and turn that suspense all the way up to eleven before cutting to the next scene, releasing all of that built-up tension in one, euphoric edit.
If you want to know how to create one of these audio swells, check out this tutorial by Zach Ramelan. In it he shows you a few different techniques you can use in Premiere Pro, as well as several sound effects that are perfect for this kind of transition.
Okay, let's just say it. Audio swells are the Wilhelm Scream of audio transitions—except not, because they haven't yet reached that level of overuse that they've become adorable and traditional. But just because something is overused doesn't mean that you can't use them; you just might want to use them sparingly, creatively, and in the right places.
