 It is possible with (curses-ansi escapes) TUI vary sine parameters -
 Frequency and amplitude.
  Possible with restrictions:
 You cannot call blocking functions in jacks process() function.
 Thus non-blocking inter-thread communication may be necessary.

 Is it possible this program __as_is__ rewrite for jack output ?

 Jack Audio uses a _callback_ based api.
 What you have there is not.

 You could re-use the above code with simple adjustments
 by adding an additional bridging library.
 (Eventually causing loss of realtime capabilities.)

 Look at :

 bio2jack  --  http://bio2jack.sourceforge.net/

Shouldn't be used. bio2jack both allocates memory and locks a mutex in 
the process callback.
(yes, it still does, look at the code on sourceforge)

Good advice. jackasyn is made properly.
