Perception
“You can put engineers in a room and give them the task of lowering distortion, and they will do this merrily for years.
But there’s a basic question: does this mean anything with respect to perception?
The distortion — though you can read it on meters — maybe isn’t audible. Well, if it isn’t audible, what are you doing that’s worthwhile here except achieving some particular engineering goal?â€
