Get Meta Data by Damien Di Fede.

This sketch demonstrates how to use the getMetaData method of AudioPlayer. This method is also available for AudioSnippet and AudioSample. You should use this method when you want to retrieve metadata about a file that you have loaded, like ID3 tags from an mp3 file. If you load WAV file or other non-tagged file, most of the metadata will be empty, but you will still have information like the filename and the length.

import ddf.minim.*;

Minim minim;
AudioPlayer groove;
AudioMetaData meta;

void setup()
{
  size(512, 256, P2D);
  
  minim = new Minim(this);
  groove = minim.loadFile("groove.mp3");
  meta = groove.getMetaData();
  
  textFont(createFont("Serif", 12));
  textMode(SCREEN);
}

int ys = 25;
int yi = 15;

void draw()
{
  background(0);
  int y = ys;
  text("File Name: " + meta.fileName(), 5, y);
  text("Length (in milliseconds): " + meta.length(), 5, y+=yi);
  text("Title: " + meta.title(), 5, y+=yi);
  text("Author: " + meta.author(), 5, y+=yi); 
  text("Album: " + meta.album(), 5, y+=yi);
  text("Date: " + meta.date(), 5, y+=yi);
  text("Comment: " + meta.comment(), 5, y+=yi);
  text("Track: " + meta.track(), 5, y+=yi);
  text("Genre: " + meta.genre(), 5, y+=yi);
  text("Copyright: " + meta.copyright(), 5, y+=yi);
  text("Disc: " + meta.disc(), 5, y+=yi);
  text("Composer: " + meta.composer(), 5, y+=yi);
  text("Orchestra: " + meta.orchestra(), 5, y+=yi);
  text("Publisher: " + meta.publisher(), 5, y+=yi);
  text("Encoded: " + meta.encoded(), 5, y+=yi);
}


void stop()
{
  // always close Minim audio classes when you are done with them
  groove.close();
  // always stop Minim before exiting
  minim.stop();
  
  super.stop();
}
