The result is what you see in the following screenshot:
Now, under the
ElementBG
layer's
Element
effect, create an expression on the
Scatter
parameter. It should read as follows:
thisComp.layer("Audio Amplitude").effect("Both
Channels")("Slider")/2
This expression takes the
Both Channels
slider, divides the value in half, and assigns
it to the
Scatter
parameter. Now, on the
Surface Offset
parameter (two items
above the
Scatter
parameter), use the following expression:
effect("Element")("1. Scatter")
This expression ties the surface offset to the
Scatter
parameter's value. There we
have a cool background!
Finally, add the following expression to the "Glow" "Intensity":
thisComp.layer("Audio Amplitude").effect("Both
Channels")("Slider")/2
This method can be used for any parameter and any effect. You can use audio to
control all kinds of cool stuff in AEX.
Finally, let's change the comp's background color to white and turn on the depth
of field. The result should look like the following screenshot:
