hi there
I didn´t know before what Trapcode Sound Keys exactly does, but after I had seen this tutorial I thought about a way to achieve the same without this plugin:
You have to create a Solid with the "audio spectrum" effect on it. Then create a Null Object and position it exactly on a specific part of the audio spectrum like it is done in the tutorial with soundkeys. Then apply a expression slider with the following expression:
target = thisComp.layer("your musiclayer");
p = target.fromComp(this.toComp(transform.anchorPoint));
s = target.sampleImage(p,[transform.scale[0]/2,transform.scale[1]/2],true)[3]*100;
the slider now will give you values from 0 to 100 depending on how much the Null-Rectangle is covered by the audio spectrum. Works very nice.
Does anyone know a way how to then apply a falloff to this expression values, similar how it is done with soundkeys? So that the values do fade back smoothly and not so abrupt?
Hi there
Mattrunks, your tutorials are great, thank you a lot.
In addition, i have made up some expression to put on the position of the magnified layer:
s = transform.scale[0]/thisComp.layer("Insert Small Fit").transform.scale[0];
x = thisComp.width/2 + (thisComp.width/2 - thisComp.layer("lupe").transform.position[0])*(s-1);
y = thisComp.height/2 + (thisComp.height/2 - thisComp.layer("lupe").transform.position[1])*(s-1);
[x,y]
Now you will always have the correct magnified piece and dont have to fit the position of this layer. Does it work for you?

I forgot to mention to change the anchor Point of the Null to 50,50 to make it work correctly.

sorry, of course it is the "audio spectrum layer" not "your musiclayer" in the mentioned expression.
