  Audio and expressions to create more responsive and customizable shapes/waveform

  Posted by Ivan Gadioli on October 14, 2020 at 6:47 pm

  I’m working on a project that I need to have more control over the audio bars to change the shape, peak sound … Something more detailed in control than the “audio spectrum” or “audio waveform” effect.

  to be more specific, I need the bars to follow the pattern of the song while I have control over the initial form of it. And i even got it, but i didn’t get the correct “waveform”, but a lot of shapes that moved in the same way.

  i try to aply this expression of Dan Ebberts (http://www.motionscript.com/design-guide/basic-audio.html)

  then I put controllers in the values of min,max,stretch ​​and limited the movement to the Y axis.

  minAudio = 0;
  maxAudio = 15;
  maxStretch = 2.0;
  
  audioLev = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
  
  stretch =  linear(audioLev, minAudio, maxAudio, 1.0, maxStretch);
  
  [100, 500 * stretch]

  And it did what i wanted, but only for a single shape. I have no idea how i would take the waves and divide them between several bars so a i can control thrie size and shape. =/

  Is there any technique or logic to work with db em AE?

  I hope i managed to get through what is my doubt hahaha. Thanks for those who can get me out of this mess.
