Digital audio myth debunked here with evidence in physics mathematics and chemistry. The chemical makeup of the vinyl record has influence on the physics and the mathematics of what your stylus and cardridge (moving magnet / moving coil) will pickup.
Be amazed at the fact that the signal remains smooth when going through AD DA conversion all the way up to the Nyquist frequency

It’s always fun when the wind speed exceeds the Nyquist Limit of the Doppler radar, confusing it into thinking the wind is in the other direction.
(The red bits in the attached image are not “away from” the Mt Koonya radar, but instead toward it at something more than 90 km/h)

@fgirault @tth En fait, il faut le dire, #superCollider c'est quand même assez tripant ! J'ai acheté https://ccrma.stanford.edu/~ruviaro/texts/A_Gentle_Introduction_To_SuperCollider.pdf en arbre mort chez https://www.lulu.com/ et j'essaye de m'imprégner de la logique interne du machin. Entre ça, #Chuck et #Nyquist, il y a de quoi faire de la ligne de code bien sonore 📢 -

I stumbled onto some guy's video defending the use of 192K for recording all audio, and I admit I didn't watch all of his video, because a minute or two in, he said "Besides, the Nyquist Theorem IS JUST A THEOREM."
When guys like him start to sound like young earth creationists, who often say "The Theory of Evolution IS JUST A THEORY..." they lose all credibility.

This video on digital sampling is still extremely relevant: https://www.xiph.org/video/vid2.shtml
I again saw a video today claiming that the quality of a digital signal degrades as you approach the Nyquist frequency (half of the sampling frequency). No. That's just not true. A band limited signal, containing information of to a frequency f, can be captured *exactly* by sampling it at any frequency larger than 2f. If you sample a band-limited signal according to this limit and then pass it through a digital to analogue converter you get *exactly the same thing* as you started with. Even if it contains data at 22 kHz and you sample it at 44.1 kHz. (But you really want it to contain nothing above 22.05 kHz or it will be aliased and you will definitely lose data).

TIL that CD audio is at 44.1 kHz because humans can only hear up to 22.05 kHz and by the #Nyquist sampling theorem, if we sample at twice the frequency we get a perfect recreation.

I still think this is a mandatory watch for everyone working with digital sound :) "Digital Show & Tell" by Monty Montgomery from Xiph.org - or why digital audio is perfect:
