Pulse expression edit
I need an edit on this expression
minAudio = 0;
maxAudio = 100;
minStretch = 90;
maxStretch = 130;
audioLev = thisComp.layer(“Sound Keys”).effect(“Sound Keys”)(“Output 1”);
s = linear(audioLev, minAudio, maxAudio, minStretch, maxStretch);
[s,s]Instead of it stretching I want it to control the opacity so when the audio level is 100 the opacity will be 130 as the max. Yes, I used Sound Keys to isolate bass so it will react to bass, help please!

I’m not sure why you would want opacity to go to 130, but editing the expression should be pretty easy. All you need to do is remove the last line:
minAudio = 0;
maxAudio = 100;
minStretch = 90;
maxStretch = 130;
audioLev = thisComp.layer(“Sound Keys”).effect(“Sound Keys”)(“Output 1”);
linear(audioLev, minAudio, maxAudio, minStretch, maxStretch);Dan

Lol thanks but i meant like if the audio goes to 100 then the opacity will go to x%(whatever number i choose)
-
Then I say choose one and set maxStretch accordingly. ????

Thanks, Dan! Would you tell me what does “s” means in this expression?

It’s just a variable name. I could have used anything. The purpose of the variable is to temporarily store the value of the linear() interpolation so I can use it in the next line so that the scale will be the same for x and y.
