This is easier and less error-prone than copying the oops down by hand?
I remember using 300 bps. On a closed electrical circuit without acoustic couplers, you still got line noise. Acoustic couplers put the speaker and microphone right on top of each other and surrounded them with a muffler to try to minimize ambient noise from the room...

Not everybody has a tape recorder, though.
And the -ac branch already does output in morse code. Try taping that and writing a user mode interpreter for it, if you like...
