title: javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input file when loading wav file
body: <p>i am using <strong>java 6</strong> , and i am trying to load <strong>wav</strong> file, to get its duration as follows:</p>
  
  <pre><code>public static double getAudioFileDuration(File file) {
          try {
              AudioInputStream stream = AudioSystem.getAudioInputStream(file);
  
              // At present, ALAW and ULAW encodings must be converted
              // to PCM_SIGNED before it can be played
              AudioFormat format = stream.getFormat();
              if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
                  format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
                          format.getSampleRate(), format.getSampleSizeInBits(),
                          format.getChannels(), format.getFrameSize(),
                          format.getFrameRate(), true); // big endian
                  stream = AudioSystem.getAudioInputStream(format, stream);
              }
              DataLine.Info info = new DataLine.Info(Clip.class,
                      stream.getFormat(),
                      ((int) stream.getFrameLength() * format.getFrameSize()));
              Clip clip = (Clip) AudioSystem.getLine(info);
              // clip.open(stream);
              double durationInSecs = clip.getBufferSize()
                      / (clip.getFormat().getFrameSize() * clip.getFormat()
                              .getFrameRate());
              double minTemp = Math.round(Math.round(durationInSecs) / 60.0);
              double durationInMin = minTemp
                      + (((Math.round(durationInSecs) / 60.0) - minTemp) * 60)
                      / 100;
              return durationInMin;
  
          } catch (Exception e) {
              e.printStackTrace();
              return 0;
          }
  
      }
