Linking the Bulge effect to an Audio Amplitude layer to get a beat
on Dec 12, 2011 at 9:47:59 pm

I have an expression that I have used to link an Audio Amplitude layer to the Taper Radius of the Bulge effect. I want the bulge effect to become bigger and smaller to the beat of the music.

The expression I have works but the movement is so slight that you can barely see it. Is there a way to have a value range to intensify the effect of the bulge beating such as a max and min?


This is what I have as my expression:

thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")

Like this, probably:

aud = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
audMin = 0;
audMax = 20;
taperMin = 0;
taperMax = 100;
linear(aud,audMin,audMax,taperMax,taperMin)
