A couple of friends have pointed me to this piece of egregious nonsense over the last week. If you haven’t already seen it, you can watch the [largely ridiculous] clip here (I can’t embed it, since it’s some kind of proprietary format).
In any case, the image above tells you everything you need to know; basically, a piece of Vivaldi plays while you watch a spiky and glitchy circle wobble (on the left), which is meant to represent a ‘typical’ CD recording. Meanwhile, on the other side of the screen, a circle supposedly representing a ‘typical’ analog recording also does its wobbly thing, only with curvier lines and colour.
This piece of claptrap offers up a much perpetuated myth about digital recording: that somehow the discrete sampling bits make digitally recorded music sound spiky and colourless, and inferring that analog must certainly be better because it’s more ‘natural’ (or something). Worst of all, the video is useless even as an analogy because it literally doesn’t convey ANY information. It is the equivalent of the old Colgate ‘Mrs Marsh’ advertisement of the 1970s:
It’s bogus ‘science’, appealing only to those who think they understand something, but really don’t.
I’ve said it here before, but I’ll say it again: the quality of a well mastered CD recording is not, in any way, inferior to a vinyl LP. Vinyl is different, and that is all. If you think you can hear a difference in high frequency content, you can’t. If you think vinyl sounds ‘punchier’ and ‘warmer’, you’re probably hearing the effects of the substantially different mastering techniques that are used for vinyl (and that’s mostly equalization and compression).
And before you start to take exception to what I’ve just said, go here and witness a whole lot of people who think like you do failing to be able to tell the difference between cables, amps, DACs and all kinds of formats in controlled blind and ABX listening tests. Mostly to their own disbelief.
