Btw I forgot to add that I'm currently= doing a lot of stuff synced to audio and I'm finding the results are better= if I posterise time down to 10-15 Fps. There's so much variation in audio t= hat using key frames or waveforms at full frame rate can become very flicker= y.  As mentioned earlier, the mosaic effect may be all you need but it w= ill Flickr at 30fps, so try using posterise time with various frame rates.

more spe= cifically, 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 f= or you it helps to see how it looks.

then if you want it driven by audio, convert that tracks audio to ke= yframes using teh keyframe assistant and then add this expression to the rep= eater

a=3Dthis= Comp.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 t= hen set it to 0,6

aharon rabinowitz showed how to use a shap= e layer as a VU meter a long time ago, as an example of ways to use shape la= yers :)
