Firstly, the subjects need to be separate from the background, so you would need a clean background plate and the subjects should be shot in front of a green screen or rotoscoped. To create the transparent cloaked effect, you would need to roto a depth map over the subject, similar to how they do 3D conversions, and use that as input for the displacement effect. I could see the underlying energy effect being created with fractal noise and vector blur, then being displaced and masked using the depth map. That’s how I would initially approach the shot.

I show an efficient way to do this in a previous post:

What does your depth pass look like? This plugin wants a depth pass where white is closest to the camera and black farthest from the camera. Sometimes if the depth pass is inverted it will give strange results like this.

Do the white lines in the source comp consist of individual layers with opacity property? If so, put this expression in the opacity property of one layer, copy expression only and paste to all other layers in the main comp. It will copy the opacity of the white shapes based on layer order.
comp("source comp").layer(index).transform.opacityPeter Diefenthaler

Something like this should work.
min = 0;
max = thisComp.layer("Null 1").effect("Slider Control")("Slider");if(numKeys > 1){
ease(time,key(1).time,key(2).time,min,max);
}else{
max;

Whoops, Dan beat me to the punch. Anyway, this method works also, but probably isn’t as elegant of a solution.
sliderPos = Math.round(thisComp.layer("B_CHEST").effect("BODY POSES")("Slider"));
switch(sliderPos){
case 1:
[x,y];
break;
case 2:
[x,y];
break;
case 3:
[x,y];
break;
default:
value;

You can use this technique for the entire face, or for the eyes/mouth individually. This is a common method for cycling through phonemes as well.
// Each frame corresponds to a different emotion state, starting with frame zero.emotionSlider = thisComp.layer("Controls").effect("Emotion Slider")("Slider");

I’m not sure I completely understand what your goal is. Could this be what you’re looking for?
freq=0.6;
min=12;
max=300;Math.abs(wiggle(freq,max-min))+min

This video shows how to link the output data to a parameter. Just pick-whip the sound keys output.
