Controlling Zig Zag area in Shape Layer using a Gradient ramp
I have a shape layer stroke on which I have used Zig Zag modifier to create a ripple effect. I have then connected the size of the Zig Zag modifier to Audio Keyframes.
Sample Image 2 is the effect I want
Sample Image 1 is the effect that I haveSample Image 3 is the composition I have
I want to be able to control the spread of this ripple and have it happen only where I want.
I looked up a tutorial on YouTube that gave me an idea of a Gradient ramp expression, but the controls I am using is different.
I would appreciate some direction as to how to go about this.

That’s not possible, the effector on the Shape’s path is something very different to a pixel-effect. There’s no way to limit it’s range or strength or mask it in anyway.
The only way I can think of is with expressions in the shape path’s but that would be pretty complex to program.

BTW, if it doesn’t need to be vector/shape:
There’s a neat trick you can do with creating an audio Tone and then rendering it with Audio Waveform
here is the project-file:
