CS 111 - 11/17/16

If we embed character information into the
  sound sample values, the resulting data
  will look like a normal sound sample


We want to replace the lower order bits of the
  sound sample value with the ascii character
  information.

Each sound sample is encoded in 16 bits

Each ASCII character is encoded in 7 bits

We want to replace the last 7 bits of the
   sound sample with the data from the 
   ASCII character

The modulus operator can determine how far a
  value is over a multiple of 1281
  
  remainder = value % 128

  modValue = value - remainder

Assume we have the following value 
   (shown in binary)

  value:     1110 1001 1101 1110
  remainder:            101 1110
  modValue:  1110 1001 1000 0000 

a = decimal value 96
    binary value of  110 0001

The embedded result is with the a hidden in
   the sound sample is:
              1110 1001 1110 0001

   character = 'a'

   asciiNum  = ord (character) # number of 96

   finalValue = modValue + asciiNum
