  Fadeout/in on Sound Layers by expression

  Posted by Lutz Krekel on September 15, 2021 at 3:18 pm

  Hello, try to do a fade Out fade In Expression for Sound Layers in Time Responsive Morgts.

  May anyone could help me?

  Should detect In and Outpoint by using inPoint and outPoint and fade during 20 frames from minus 40 to 0.

  This expression should work, I think:

  var fadeTime = 3; // in seconds
  var soundLevel = 0;
  var noVolume = -96;
  var level = noVolume;
  if (time < inPoint + fadeTime){
  level = linear(time,inPoint,inPoint + fadeTime,noVolume,soundLevel)
  }else if (time < outPoint - fadeTime){
  level = soundLevel
  }else{
  level = linear(time,outPoint - fadeTime,outPoint,soundLevel,noVolume)
  }
  [level,level]
