Vibrato
 | This article is a stub! It is missing critical information, likely just standing ground until it is completed later. Come back soon! |
Vibrato is a type of audio distortion that modulates the pitch using a wave pattern over time, without changing the speed of the footage. In other words, it makes it sound "dizzy" or "sproingy".
Usage
The easiest way to use Vibrato historically is with Vegas (which has a built in plugin) and Audacity (which does as well). Premiere doesn't have one, but MVibrato is a solid alternative.
