I wouldn’t spend any time learning Motion Math because it’s been removed from AE in newer versions. Anything that you would absolutely need Motion Math for you can do with a combination of expressions and scripting. The best resource for scripting is the AE Scripting Guide pdf. It’s a pretty steep learning curve until you get familiar with AE’s object hierarchy, but it’s worth the trouble.

Something like this should get you started:

freq = 4.0;
decay = 1.0;
v = -100*(Math.cos(freq*time*2*Math.PI)/Math.exp(decay*time) – 1);
[v,v]

Are your layers rectangular pixels by chance? That’s a guaranteed headache. I’d use square pixels in a square pixel comp.

Change the blending mode of your layers to “Alpha Add” – it should help.

I think that would definitely be easier – if you can express the altitude as a function of time.

It sounds like you need a script to read and parse the file. Is it a text file?

You could try the smooth() method like this:

temp = thisComp.layer(“Audioamplitude”).effect(“Linker Kanal”)(“Schieberegler”).smooth(.2,5,time);
[temp, temp]*30 + [25,25]
