Note the words "in general".  Your brain (not your ears) applies quite a
bit of processing power to make sense out of what it's hearing.  Once it
has done so, it has enough extra information to solve the problem.  It
couldn't do this for random input; the extra information is available
only because the input "makes sense".  Duplicating this process with
electronics doesn't sound easy to me.
