making different images appear using audio amplitude...
by Fernando Lopez on Mar 2, 2008 at 9:23:34 pm

I saw a reply to a post that contained this expression:

temp = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
value + [0,15]*temp/5;

You would add the expression to a layer, after doing the "convert audio to keyframes" under the keyframe assistant.


Instead of making an image move 15 pixels down when the audio level is 5, I want a different image coming up when the audio levels are 15. Then a different one at 8, then a different one at 0.

I need help on this, please. Thanks guys!

You could apply this opacity expression to the top layer:

temp = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
if (temp > 15) 100 else 0;

Modify it like this for the next layer down:

temp = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
if (temp > 8) 100 else 0;

The bottom layer wouldn't need an expression.

Dan
