 Summary of the bug:
 I have a wav file that has the incorrect duration in the file properties
 (in windows Right Click > Properties > Click Details tab) and when I get
 the duration it shows the incorrect one from the file properties.  If I
 convert the file to an MP3 and then get the duration it shows correctly.

 Why is the duration on the wav file incorrect?

 Below is how I am getting the duration:
