At the end of Aauto Quicker's Tik Tok joke, what software is used to repeat and slow down the sound when the characters get bigger?

You can make a fast movie app or a clip movie app. You have to cut and copy the last clip, and then change the speed of this clip. The speed will slow down and the sound will change accordingly. Just turn it up a little.
