Hans is a longstanding audio writer.I recognized that name and face, and not for the good. He advocates 192 kHz for end-user format out of his willful ignorance of audio. Someone at audiosciencereview posted this screenshot for public ridicule:
Let's see ... we know bat sounds can reach up to 250 kHz, that is more than three octaves over what any human ear has ever heard. How do we know it then? Because we can measure it. (Of course, because the equipment can handle and process sounds way beyond human hearing, we can also play it back at 1/32th speed so you can hear it.)
If it looks like a quack, quacks like a quack, and ducks like a quack, it probably is a quack.
