audio amplitude and expressions, keeping a controlling scale
Hi,
I’m using the audio amplitude/audio expressions for the first time. It’s working great so far. My expression looks like this:
temp = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”)*13;
[temp, temp, temp]I’d like to keep the object that is scaling from disappearing when the sound get quiet. Is there a to adjust this?
Thank you,
Heather

You can use something like this (you’ll have to adjust the first four parameters to fit your project):
minAudio = 0;
maxAudio = 15;
minScale = 10;
maxScale = 100;myAudio = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
temp = linear(myAudio, minAudio, maxAudio, minScale, maxScale);

Thanks Dan!
I’ll give it a shot. I really appreciate your help!
