Mmmmm....


The old dialup telephone modems did the same thing, only a lot better, 
because they stuffed the bits into 4kHz audio bandwidth;

current computer audio can do substantially better than 4kHz.

These protocols are still being used -- e.g., ham radio, broadcast radio 
(to display the the title of the current music being played), etc.

You can even use touch-tones, if you're a 5th grader !
