Hi Adam,

I’m also a beginner, but try the expression attached. If you connect the variable maxVal with an additional slider you can also change this value over time.

maxVal = 80;
if (thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider") >= maxVal) {
100}
else {
0}

Hi all,

is there any documentation about which index / number represents a property?
This would be very helpful!

Thanks a lot!
Anna

Thank you both!!
Dan Ebbert’s approach do work well. Dan Fredley’s suggestion do not, since one cannot “look for property by name in group stroke” within an expression.

And as I saw the end point of the stroke is then value[1].

Thank you once again!
Anna
