I'm using SoX for nearly everything. For generating the band-limited square wave I have this script, which uses SoX internally. Earlier you showed non-band-limited square wave and that's what's illegal: For comparison, 100 Hz square wave at 44.1 kHz sampling rate, bandlimited vs not bandlimited:

Somehow I'm not surprised that you would think that. It's actually all the frequencies: I'm worried that you'll take it and misrepresent in your usual fashion, but ok. Everything as before, I only changed the Ref Level in ADI-2 from +13 dBu to +4 dBu because the max output from the laptop is...

I generated this impulse at 352.8 kHz: The left channel is delayed by 1 sample (2.8 µs). I converted the file to 16/44k: I played the 16/44k file on Lenovo T480s through its on-board card (ALC257) and captured with RME ADI-2 Pro FS R BE at 705.2 kHz sampling rate: The delay was...

More relevant? I guess that depends on what weights you assign to the attenuation (due to the inverse-square law) vs duration of the signal :-). They both will be attenuated the same way. The long-lived signal will be easier to detect/extract from the background noise than a short-lived "blip"...

Inverse-square law I presume.

Almost (or exactly) like "stairsteps" in digital audio :-)

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:

I would even like "Driving Me Too Hard" but the crackling annoys me too much. I can't comprehend why someone would want it on purpose, so on the one hand I like to believe it's a mistake that went unnoticed but on the other hand I can't really believe that such a mistake, in such an album, would...

More like: less distortion for more uncorrelated noise (white or shaped). As for accuracy, when you convert signal at level below least significant bit, without dither you get zero, with dither you get noisy signal. Are you saying that "no signal at all" is more accurate than "the signal" with...

I would call for including a dead salmon in the study :-) Would it? IMO that's rather questionable implication.

And the most important are those gold plated plugs ;-) ;-) ;-)
