Um.. definitly
But it has less to do with the absolute position of the sound..
For example, you wouldn't listen for s then u then p then e then r..
you would listen for general position like left and right hand, THEN you would listen for Rhythm
(left sound) s........ (right sound) u..p........ (left sound) e.r.
The periods represent relative delay.. notice up and er would have relatively little delay
haha.. This could make for a good project for that guy doing a school project.. someone message him.
HERE's the thing though.. You have to be a very good typer, for your password to be cracked in this way..
If you're a hunt and pecker, with less mastery of the keyboard arts. getting a pattern match from your typing would be far more difficult.
