Problem with interpolation expressions controlling position/rotation
Hello folks,
I’m really bad at coding but somehow I managed to put together some eyebrown animation based on audio amplitude + position/rotation interpolation expressions but it came out very choppy 🙁
The thing is: I got the eyebrowns (which are represented by a red shape at the moment) of my character to move when the audio amplitude peaks but I need the movement to be smoother
Here’s a piece of the animation so you can see what I’m talking about:

Edit: My goal here is to animate the eyebrowns only when the audio peaks to give some surprise/enthusiasm look on the face and to accomplish that I’m using the highest values of the audio peak as trigger but if you guys have a better idea I’m all ears 🙂
And heres the expressions:Position:
volAmp = thisComp.layer("cabeca inteira boca fechada").effect("Voice Volume")("Slider");
ease(volAmp, 80, 90, [706,260], [706,250]);Rotation:
volAmp = thisComp.layer("cabeca inteira boca fechada").effect("Voice Volume")("Slider");
ease(volAmp, 70, 90, 0, 5); -

My guess is that what you really want is an animation that is triggered by the audio level going above a certain value. That’s a more complicated application. Hopefully this will explain the issues and how you detect the peaks:

You’ll probably want a different animation than the oscillation example, but if you get that far come back and ask more questions.

That’s a approach that I haven’t considered! I’ll give it a try, thanks!
