I found solution that work for me, here is expression:

threshold = 85.0;
audioLev = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
above = false;
frame = Math.round(time / thisComp.frameDuration);
while (true){
  t = frame * thisComp.frameDuration;
  if (above){
    if (audioLev.valueAtTime(t) < threshold){
      frame++;
      break;
…

Also if i writte expresion just with if and linear, it while now execute, beacuse next frame value is less then 85, and it back [0,0]

Thanks for the answer, but what would happen if animation need to start again before previous one isnt finished.

Animation need to follow bass on music, so i may happen there are overlapping

Hi,
I need to write expression for position that will be triggered when audio pass specific value and it can repeat multiple throw video.

[100,100]}

else{[0,0]}

And it works, but I want to add linear expression to y position, but dont know how to write… Read more
