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


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

--UPDATE

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

    recordedTimeInSec = audioFileLength / (frameSize * frameRate);

I know how to get the file length, but I'm not finding how to get the sound file's frame rate and frame size... Any idea or link?

-- UPDATE

One more working code (using @mdma's hints):

    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));

Solution

  • 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();
