What exactly are you referring to with those numbers? I can't tell if mean the width of the pass band or level of the signal (but why at Nytquist)? Aliasing? In a DAC? Or did you mean images, between 22 and 24 kHz.

It's only a penalty if you think that the ripples are something wrong. I've never heard any convincing explanation why that would be. Most of the time it's just hand-waving and saying "look, this one is flat before and after the impulse so it must be better" and what I see is "look, the filter...

I'm sure you're only asking /s 🤦‍♂️ Here you have it: https://xiph.org/video/vid2.shtml

I never said it was. That's why I replied.

According to wikipedia: https://en.wikipedia.org/wiki/Speed_of_electricity#Electric_drift 8 cm/h is 0.002 cm/s

Not sure if it helps, but I did that, in practice :), with a piece of music: https://www.audiosciencereview.com/forum/index.php?threads/master-thread-are-measurements-everything-or-nothing.29062/page-258#post-1426610

Sure, it is legal but it doesn't mean it is not ridiculous at the same time, unless you can show it happens often enough to be worth worrying about. You use the word "possible" again :xf_rolleyes: but how probable it is?

With what probability? Please describe the conditions. Frankly, that will be more interesting than the recording. Really? I thought it is manipulated every time it is played :wink: But anyway, the information contained in the pits and lands of a CD also can't be manipulated. I wish you best...

Sigh... way to miss the point. The point isn't whether it is correct once or never. The point is that it's a broken clock. The point is, don't disparage all clocks based on what a broken one is showing. There are plenty of working clocks, use them instead. How often is this condition you're...

There are cases of clocks that show correct time only twice a day therefore sun dials are superior 🤦‍♂️

Can you provide an example of such artifact, before and after it is fixed?

To that point, here's a spectrogram of a few different frequencies clipped by 3 dB (at 48k sampling rate). It starts with 3'000 Hz, where aliased harmonics overlap. Then the frequency of the tone is reduced, doubling the difference at each step (see the labels at the bottom) and the aliases are...

Really? So where does it say that ABX/DBT can't last long?

I don't see anything there and the last post is from 3 weeks before the other thread. That other thread however, I have only google-cached version but I can imagine how it ended:
