How do I get a mp3 file's total time in Java?
- by Tom Brito
The answers provided in How do I get a sound file’s total time in Java? work well for wav files, but not for mp3 files.
They are (given a file):
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file);
AudioFormat format = audioInputStream.getFormat();
long frames = audioInputStream.getFrameLength();
double durationInSeconds = (frames+0.0) / format.getFrameRate();
and:
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file);
AudioFormat format = audioInputStream.getFormat();
long audioFileLength = file.length();
int frameSize = format.getFrameSize();
float frameRate = format.getFrameRate();
float durationInSeconds = (audioFileLength / (frameSize * frameRate));
They give the same correct result for wav files, but wrong and different results for mp3 files.
Any idea what do I have to do to get the mp3 file's duration?
