We'll start with the easiest thing you can do with Minim, and that is playing an audio file. But since this might be a little too easy, we'll add a basic interface, so that you can control the audio with your keyboard and mouse.
Create a new sketch and save it as playing_audio_files.pde. Import the minim library to your sketch, just like you learned in the first recipe of this chapter. You also need to add an MP3 file to your sketch. Go find your favorite song on your hard drive and drag it onto the Processing editor to add it to the data folder of your sketch.
The first thing we need to do is declare a Minim object and an AudioPlayer object, right before the setup() function.
Minim minim; AudioPlayer player;
Inside the setup() function, we'll initialize the minim object, load the MP3 file from the data folder, and play it.
void setup()
{
size( 640, 480 );
minim = new Minim( this );
player = minim.loadFile("song.mp3");
player.play...
