more specifically, create a small rectangular shape layer.

add a repeater with its transform set to 0,-100 so that it goes up.

set the copies to 6 (though the expression will take care of this for you it helps to see how it looks.

then if you want it driven by audio, convert that tracks audio to keyframes using teh keyframe assistant and then add this expression to the repeater

a=thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")

Math.floor(linear(a,1,20,1,6))

If you look at the audio paremeter in the graph editor you can get a good idea for the input which i used 1,20

then the linear remaps those values from 1,6

if you want the VU meter to go completely off then set it to 0,6

aharon rabinowitz showed how to use a shape layer as a VU meter a long time ago, as an example of ways to use shape layers :)

Shape layer. Use a repeater driven by the audio amplitude. Linear expression to set how many units. And for no partial blocks pipe the audio amplitude through a Math.floor for whole units
