Determining the Duration of a Sampled Audio File
To create a DataLine object, see ``Loading and Playing Sampled Audio'' and ``Playing Streaming Sampled Audio''. 

 
 double durationInSecs = dataline.getBufferSize() /
     //The next two lines should be in one line
     (dataline.getFormat().getFrameSize(
       ) * dataline.getFormat().getFrameRate());
