Hello, i'm trying to learn how to  use processing and the minim library.
I've wrote a little program.But it runs very slow.


package musique;
import processing.core.*;
import ddf.minim.*;

public class Ifreq1 extends PApplet {

private static final long serialVersionUID = 1L;
Minim minim;
AudioPlayer player;
float ut=1;

public void setup(){
 size(640, 640);
 smooth();
 minim = new Minim(this);
 player = minim.loadFile("/home/gregoire/Public/bauhaus - in the flat field/cp.mp3");
 player.loop();
}

public void draw(){
 background(255);
 stroke(0);
 float[] left = player.left.toArray();
 float[] right = player.right.toArray();

 for ( int i = 0; i < left.length - 1; i++ )
 {
       //stroke(random(100),random(0),random(0));
       if(left[i]>0.00001){
            fill(random(90),random(190),random(30));
       }
       else{
           fill(random(255),random(200,255),random(255));
             stroke(255);
       }
   float x1 = map(i, 0, player.bufferSize(), 0, width);
   float x2 = map(i+1, 0, player.bufferSize(), 0, height);
ellipse(100+height/3-right[i+1]*120,x2*10,height/3-left[i]*150,x1*10);
}
}
public void stop(){
 player.close();
 minim.stop();
 super.stop();
}

You see, this program is very bad for complexity.
Is there a way to reduce this complexity? I have just one idea, but i don't know how to do it : Is it possible to get :
float[] left = player.left.toArray();
float[] right = player.right.toArray();

before launching the song ? (i don't really understand the way minim works so..)


Thank you for reading this and i wish you a nice and pleasant day.

Hmm thank you but with the P2D mode, it looks the same without smooth() and the speed stills low.
