Hello.

This could potentially be a very simple question. I am working on a project where an object reacts to the tone and volume of a voice through microphone. I am trying this first by using the sample code for the GetLineIn minim library.  I made the draw function this :

void draw()
{
 background(30);
 stroke(255);

 for(int i = 0; i < in.bufferSize() - 1; i++)
 {
float total = in.mix.get(i);
   float diff = in.right.get(i) - in.left.get(i);
   int s = round(total * 200) + 10;
   int y = width/4;
   ellipse(500 - (diff * 500), y, s, s);
 }
}

It is not very effective. I want it to redraw the shape in X according to volume, and Y according to tone, while keeping the position and not jumping back as soon as the sound ends.
Help?
Thank you.
