Imagine you were born deaf and couldn't hear music. But that someone showed you a music visualiser.
Do you think if you were watching the output of that visualiser you would now know the music in some meaningful way?
You seem really hung up on some pedantry about "see" and "seeing". Why? This may seem like some kind of strong criticism to you, but it just seems as though you are unaware of these technologies and haven't really thought through what constitutes a measurement or observation.
