How do I get a sound file\'s total time in Java?

--UPDATE

Looks like this code does de work: long audioFileLength = audioFile.length();

Answer 1

This is a easy way:

FileInputStream fileInputStream = null;
long duration = 0;

try {
    fileInputStream = new FileInputStream(pathToFile);
} catch (FileNotFoundException e) {
    e.printStackTrace();
}

try {
    duration = Objects.requireNonNull(fileInputStream).getChannel().size() / 128;
} catch (IOException e) {
    e.printStackTrace();
}
System.out.println(duration)

Answer 2

Given a File you can write

File file = ...;
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file);
AudioFormat format = audioInputStream.getFormat();
long frames = audioInputStream.getFrameLength();
double durationInSeconds = (frames+0.0) / format.getFrameRate();
