Why is my program lagging?

AclaS

I'm having a difficult time figuring out why my code is lagging. Can anyone help? Here's my code:

//minim imports
import ddf.minim.*;
import ddf.minim.analysis.*;
import ddf.minim.effects.*;
import ddf.minim.signals.*;
import ddf.minim.spi.*;
import ddf.minim.ugens.*;

Minim minim;
AudioPlayer songL;
AudioPlayer songR;
FFT fft;
BeatDetect beat;

//tablet import
import codeanticode.tablet.*;

Tablet tablet;

boolean music = true;

public void setup() {
  size (640, 640, P2D);

  minim = new Minim(this);
  songL = minim.loadFile("Sailing on the Wind.mp3", 2048);
  beat = new BeatDetect();
  fft = new FFT (songL.bufferSize(), songL.sampleRate());


  minim = new Minim(this);
  songR = minim.loadFile("Through the Fire and Flames.mp3", 2048);
  beat = new BeatDetect();
  fft = new FFT (songR.bufferSize(), songR.sampleRate());

  tablet = new Tablet (this);
}

public void draw () {
  background (0);
  smooth();

  songL.play();
  songR.play();

  if (music == false) {
    songL.mute();
    songR.unmute();
  }

  if (music == true) {
    songL.unmute();
    songR.mute();
  }

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


    music = false;

    //Blue square
    noStroke();
    fill (135, 206, 250, 50);

    if (mousePressed && (mouseButton == LEFT)) {
    } else {
      music = true;

      background (135, 206, 250);

      noStroke();
      fill (255, 0, 0, 5);

      ellipse (mouseX, mouseY, 50, 50);
    }
  }

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

    if (mousePressed && (mouseButton == RIGHT)) {

      fft.forward (songR.mix);

      background (0);
    }

    //white square
    noStroke();
    fill (248, 248, 255, 4);
    rect (220, 220, 200, 200, 75);

    //black line
    stroke (0);
    line (i, 310+ songL.left.get(i)*50, i+1, 310 + songL.left.get(i+1)*50);
    //blue line
    stroke (135, 206, 250);
    line (i, 330+ songR.left.get(i)*50, i+1, 330 + songR.left.get(i+1)*50);

    //flower/blood
    noStroke();
    fill (255, 0, 0, 5);
    ellipse (mouseX, mouseY, 25, 25);
    ellipse (mouseX-10, mouseY-10, 10, 10);
    ellipse (mouseX-10, mouseY+10, 10, 10);
    ellipse (mouseX+10, mouseY-10, 10, 10);
    ellipse (mouseX+10, mouseY+10, 10, 10);  
    ellipse (mouseX, mouseY-15, 10, 10);
    ellipse (mouseX-15, mouseY, 10, 10);
    ellipse (mouseX, mouseY+15, 10, 10);
    ellipse (mouseX+15, mouseY, 10, 10);
  }
}

Edit post, highlight code, press Ctrl-o to format.

You are drawing 10 ellipses for each sample. Maybe that should be outside the loop.

That did help for when my mouse is pressed, but it still lags when my mouse isn't pressed.

Can't tell what you've changed. But the white square doesn't need to be inside the loop either. And certainly not the fft.forward.
