  remapping speed of a property with audio

  Posted by Micheel Leavitt on August 19, 2009 at 6:16 am

  What I am trying to do is have a property be going at a certain speed, but speed up as an audio amplitude value increases, then slow back down as it decreases, but I want it to hold the value of the frame previous and apply the speed change to that value, because the code I am using below will go back to a lower value.

  mus = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
  x = ease(mus,1,9.5,0,1);
  time*(1.1+x)

  I am pretty sure this can only be done with a while loop, but I am not really sure where to begin to write it, only that it needs to repeat while “mus” is between 1 and 9.5, and I still want it to move even if it is under 1. (At a rate of 1.1)

  Any help with this would be most appreciated. Thanks!
