  AUTOMATIC WAY TO CALCULATE HIGHER & LOWER FREQUENCY OF THE MUSIC?

  Posted by Muhammad Atif Bashir on March 14, 2021 at 1:00 pm

  Hello everyone, I hope you are doing great.
  I am working on a template , I am all good in it but there is one thing I wanted to do which is to universalize it using expression.
  So what I am looking for an expression which can automatically finds out the lower and higher frequency of the given audio and then I can link that to my other files which are going to react on that audio.
  for example I want the opacity of an image to react with audio amplitude layer but it only reacts when the beat drops meaning when the frequency is higher , Right now I am using this regular expression on opacity:

  a = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(1);

  ease(a, 25, 55, 0, 100)

  so in here “25” is my lower frequency & 55 is my higher frequency but I want these values to be calculated every time I put the new song, I don’t have to do it manually by checking the graph.

  I hope I was clear enough to explain it.

  Thanks in advance.

  Regards
  Chouhdry Atif
