using audio to change background color, minim

edited March 2014 in How To...


Im new to processing and im trying to understand how to use minim to have audio creating a changing linear color gradient.

I understand the first part, how to get the audio in ... its just the next part. Getting the audio to do colors instead of a for ex line that changes. Any tips or some idea on where to start would be super! Im kind of stuck after hours of googling and trying...


import ddf.minim.*;

Minim minim;
AudioInput in;

void setup()
  size(200, 200, P3D);
  colorMode(HSB, 200);

  minim = new Minim(this);

  in = minim.getLineIn();

void draw()

  for(int i = 0; i < in.bufferSize() - 1; i++)
