Expression to select all active audio layers?

I'm trying to get an Array of all audio layers in the current comp that are currently ON and in frame (ie. In point < CTI < Out point).

Any tips on how to do this with expressions?

It would be something like this:

myArray = [];

for (i = 1; i <= thisComp.numLayers; i++){

myLayer = thisComp.layer(i);

if (myLayer.hasAudio && myLayer.audioActive && (time >= myLayer.inPoint) && (time <= myLayer.outPoint)){

myArray.push(myLayer);

}

}

You cannot select layers with expressions. But you can do it with scripts as suggested by Dan.
