CS 111 - 4/24/18

Office Hours will end at 12:30 today, due to a CS department event.

Project 4:

  Input:   character string to represent notes

  Output:  .wav file that plays the notes from the input


Algorithm:

   1.  Prompt the user for the input string

   1.5. Create a "empty" final sound

   2.  loop through the input string accessing each character

   2a.     Determine the frequency of the note represented by
              the character

   2b.     Create a 1/4 of a second sine wave for that frequency

   2c.     Join the current sine wave with the others created
              in the loop

   3.   explore to created/final sound

   4.   save the created/final sound


The loop to access the characters from the input string:

  # Step 1
  str = requestString( ... )
  inputLength = len (str)

  # Step 2.0
  for index = range ( 0, inputLength, 1 ):
     # access the "index"-th character
     char = str[index]


One techinical issue with the project is that the sound will
  create a "click" at every 1/4 of a second.  

  You are to ignore this technical issue.

  The solution to the "clicking" technical issue requires the
     sine wave to be shifted to a "proper" poisition.  This
     is outside of the scope of the project for CS 111 Project 4.
