While this article is now a couple months, it is no less relevant. This quote from Monty Montgomery sums up everything of import regarding hi-res music:
““Neil is advocating for good sound, and I think that is a noble and good thing that will benefit people,” Montgomery says. “I just object to where science is being misrepresented.””
He explains the ridiculous 16-bit 'stair step' graphs we are now used to seeing:
“Nonsense, says Montgomery, who explains that the samples actually serve as plot points that are used by music software to draw continuous, analog-form waves. CD-quality files are more than enough to generate smooth waves for all frequencies detectable by human ears, he adds.”
