The problem with digital representation of speed or time is that you get no sense of continuous movement. Digital clocks cause a similar warping of reality. It keeps saying that for quite a while. But my old-fashioned Timex tells me the truth. Three pointers move around the dial at different speeds.
Sound works the same way.
Anything we hear is a continuous event that starts at one time and ends at another. It's a constant flow of audible information. They're making digital sound behave as if it were analog. Two different ways of doing this were shown. The first method relies on a mathematical cold shower.
