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