File Length .mp3 or .wav with Minim and Processing

Hello guys,

Is Possible to know Which time to complete a sound (music) an .mp3 or .wav of a file in Processing, using the Minim library?

For example, I need at the end of a particular sound, perform a certain action, so I need to know when to finished.

This is the code I used as an example, although I'm using is in another project.

import ddf.minim.*;
Minim minim;

AudioPlayer player[] = new AudioPlayer[3];
String filenames[]   = new String[] {"groove.mp3", "jingle.mp3", "Kalimba.mp3"};

void setup(){
  minim = new Minim(this);
  for(int i = 0; i < 3; i++){
    player[i] = minim.loadFile(filenames[i], 2048);
  }
}

void draw(){
  //
}

void keyPressed(){
  int som;

  if (key == 'A' || key == 'a') som = 0;
  else if (key == 'B' || key == 'b') som = 1;
  else som = 2;

  playSom(som);
}

void playSom(int opcSom){
  for (int i = 0; i < 3; i++){
    if (player[i].isPlaying())
      player[i].pause();
  }

  player[opcSom].rewind();
  player[opcSom].play();
  println("Duration: "); //???
}

void stop(){
  for(int i = 0; i < 3; i++){
    player[i].close();
  }

  minim.stop();
  super.stop();
}

Thanks for attention.
