How can I make a very simple FSK(Frequency Shit Key) generator?

edited September 2018 in Library Questions

I'm trying to make a very bare bones replica of a linux program(I use windows) called minimodem.

What I'm trying to replicate is the part at 18 seconds, the transmitting part.

How would I go about creating a function that I can enter a string of text into and then it translates it to FSK modulation, at a baud rate that's changeable, and then play it? Is that even possible in processing? Am I asking too many questions? Will I answer any of my questions?
