Indeed all maths will tell you 1+1=2, 2+2=4 etc,
And the sampling theory is perfectly, mathematically correct, a signal can be digitised and reconstructed perfectly in a perfectly bandwidth limited signal, but it is yet to be achieved in the physical world, sure there’s reams of research on different filtering methods of achieving a perfectly bandwidth limited signal that has no effect on the signal being converted, and recently with the advances in processing power, it’s closer than its ever been, so then it’s argued that “close enough is good enough” to be “audibly transparent” when the human sciences still don’t know all of how we perceive, process and interpret sounds entering the ears,
Don’t get me wrong, measurements are vitally important but they are not everything, until we “know” everything about everything, and that’s down to science, with most things science asks more questions than it answers.
