  After effects audio react to plugin “Plexus”

  Posted by Din Iulian silviu on May 19, 2021 at 1:58 pm

  Hi there.

  I am trying to create an animation where the “Noise Amplitude” from Plexus noise effector, react with “Audio Amplitude” layer generated from a mp3 music file.

  I tried to pick whip the stop watch from Plexus Noise Amplitude to audio amplitude both channels, but doesn’t help much. My Plexus Noise Amplitude changing from 1300 to a 0-10 (depend by music), I would like it to be somewhere between 1000 and 1300 and music to influence this level.

  Any idea for a script or something else?

  Regards!

  If you wish to remap one range of values to another, you can use one of the After Effects interpolation methods, like linear(). For example:
  
  var audioAmplitude = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
  

  linear(audioAmplitude, MIN_INPUT, MAX_INPUT, MIN_OUTPUT, MAX_OUTPUT);
  
  In that code, replace MIN_INPUT and MAX_INPUT with the bottom and top of the range that you want to map from the Audio Amplitude, and replace MIN_OUTPUT and MAX_OUTPUT with the bottom and top of the range you wish to generate.
