Processing: v3.4  
Sound Library: v2.0.2

I’m trying to use the Sound library but when I instantiate a SoundFile object I receive this error in the console:

```auto
ArrayIndexOutOfBoundsException: 16

Oct 24, 2018 8:53:33 PM com.jsyn.devices.javasound.JavaSoundAudioDevice <init>
INFO: JSyn: default output latency set to 80 msec for Windows 7
Oct 24, 2018 8:53:33 PM com.jsyn.engine.SynthesisEngine start
INFO: Pure Java JSyn from www.softsynth.com, rate = 44100, RT, V16.8.0 (build 463, 2017-10-16)

```

This is the code which results in the error:

```auto
import processing.sound.*;

SoundFile file;

void setup()
{
  size(800, 600);
  
  file = new SoundFile(this, "song.mp3");
}

void draw()
{
  
}

```

Would be able to help me to resolve this issue? Thank you.

I think [the sound library isn’t working at the moment](https://discourse.processing.org/t/sound-library-error-when-playing-sound-files/306).  
Try the minim library.
