Snddemo - Sound Effects Demo.

      Snddemo is an interactive function evaluation/development
      program. You can use Snddemo to evaluate the functions in
      the Sefx library or as a development tool for finding the
      parameters that create the desired sound effect. The later
      use can save time by avoiding the recompile trial and error
      method.

      The parameters to the sound generation functions can be changed
      on the fly in the editing fields. Notice that any sound in the
      sound queue continues to play while you edit the fields. The
      parameters, if any, to the control functions are cycled/toggled
      when the function is invoked.

      All the functions are invoked by F-keys. When the sound
      generation functions are invoked, the current parameters are
      used even if it is currently being edited.

      The source code for Snddemo is provided for your inspection.
      It is, however, compiled with function that are exclusive to
      the Borland/Turbo C run time library. Specifically those prototyped
      in conio.h. If you have similar functions in your C compiler's run
      time library or you have an extended windows library, you could easily
      replace them. There are not that many. They are as follows:



                gotoxy()         - Locates the cursor.
                _setcursortype() - Sets the cursor type
                clrscr()         - Clears the window.
                textattr()       - Sets the text attributes.
                cprintf()        - similar to printf()
                cputs()          - similar to puts()
                putch()          - puts a single char
