Sound Manipulation
  -  sound is a wave over time
  -    we record the amplitude of the sound wave
          in a range from -32768 to +32767
       The value of 0 is the typical "at rest" value
       How many sample per second do we need?

       To cover the normal range of human hearing we
          need about 22000 samples per second

       We will typical use 22050 samples per second
           in our sound files
