title: Create a wav with hidden binary data in it and read it (Java)
body: <p>What I'm willing to do is to convert a text string into a wav file format in high frequencies (18500Hz +): this will be the encoder.
  And create an engine to decode this text string from a wav formatted recording that will support error control as I will not use the same file obviously, to read, but a recording of this sound.</p>
  
  <p>Thanks</p>
