Finding Duration of an MP3 file in Java

Question

OK so I have tried using ID3 tags to get the duration and I also tried using JMF media player.getDuration().

player.getDuration().getSeconds()

Answer 1

I use JAudioTagger to achieve this. The below code will get you the duration of an MP3 track.

int duration = 0;

try {
  AudioFile audioFile = AudioFileIO.read(new File("file.mp3"));
  duration = audioFile.getAudioHeader().getTrackLength();

} catch (Exception e) {
  e.printStackTrace();

}

You can alternatively cast audioFile.getAudioHeader() to MP3AudioHeader and use the method getPreciseTrackLength() to get a more precise duration. However, this (i believe) only applies to MP3 files and no other formats (such as WAV files).

Answer 2

I using this lib and this code :

File f = new File("path/mp3");
    MediaLocator ml = null;
    Player p = null;
    try {
        ml = new MediaLocator(f.toURL());

        p = Manager.createPlayer(ml);
        p.start();
        while (true) {
            Thread.sleep(1000);
            System.out.println("Media Time :: "+p.getMediaTime().getSeconds());
            System.out.println("Duration :: "+p.getDuration().getSeconds());
            if(p.getMediaTime().getSeconds() == p.getDuration().getSeconds())
                break;
        }
        p.stop();
        p.deallocate();
        p.close();
    } catch (NoPlayerException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

Good luck.
