  I’ve added ADBE AudSpect effect to solid like so

  getCompLayer('spectrum').Effects.addProperty('ADBE AudSpect')

  Now I need to reference the Audio Layer to the actual audio layer. How can I do that with scripting? Manualy I could do that here (first dropdown): Manualy I could do that here:
  https://take.ms/xZgdQ

  I’ve tryed doing it this way:

  getCompLayer('spectrum').property('ADBE AudSpect').property('AudioLayer') = getCompLayer('audio2');

  I get read-only error. Also, getCompLayer() function looks like this

  var activeComp = app.project.activeItem;

  function getCompLayer(objname) {
  for(var i=1; i<10000; i++) {
  var nameMatch = activeComp.layer(i).name == objname;

  if ( nameMatch ) {
return activeComp.layer(i);
}
}
}

  Play with this:

  var myComp = app.project.activeItem;
  var audioLayer = myComp.layer(“audio2”);
  var spectrumLayer = myComp.layer(“spectrum”);
  var myProp = spectrumLayer.property(“Effects”).property(“Audio Spectrum”).property(“Audio Layer”);
  myProp.setValue(audioLayer.index)

  Worked like a charm! Thank you!

  Didn’t quite get what the (audioLayer.index) does, though.
