Yep, I confess it was I. I asked if it did or not because i saw it change in R.Lees home on his ESL when the HV was lowered.
It has not been duplicated here in any fashion to speak of.

?? 192kHz was the sampling rate he used for the measurements, the envelope was brickwalled at 22.05kHz.

"It is about a physical process that goes from zero amplitude to full scale amplitude instantly. "
I get the gist of what you are trying to convey here, but just cannot get past the 'zero to full scale instantly' part that violates all known laws of physics.

And the major flaw of that has been covered for you to chew on already by more than 1 forum member. Lets see, play a cello in a room, record and listen at different spots, replay with a speaker at a different spot from cello and all is fine, right?
I most certainly did, I never brush your posts off.
Localization involves differences four orders of magnitude faster than 50 mSec.

Because you are thinking I mean a step function to maximum level. I am talking about a sine wave that is gated at zero angle. You know, turn the volume up at the exact zero crossing point.
It's not a physics violation.

It's difficult when some folks have virtually no understanding of what is going on.
The original file is 192k, the removal of everything >22,050k while keeping the 192k format avoids the actual down sampling to 44,100k and subsequent up sampling that would happen during playback. If you want to go NOS 44.1/16 then I can't help you.
I'm trying to eliminate as many confounding issues as possible, i.e. filter/algorithm choice.
JN ... I may have lost the plot here, but I think you are saying that if we take a signal equivalent to 20k carrier with 4kHz sidebands - so spectral peaks at 16, 20 & 24 kHz, then filter out the upper (above audible frequency) sideband, leaving 16 & 20 kHz components, this is equivalent to an 18 kHz signal modulated by 2 kHz with the carrier removed, leaving spectral peaks at 16 & 20 kHz again? just clarifying. Apologies if this is repetitious, but a lot of pages have gone by...
Scott, am I missing something, what's relevant is the effect of the filter not the sample rate per se?
Where does this modulation come from? How is addition becoming multiplication in a linear system? What non-linear mechanism generates the multiplication?
The addition of two sines creates a simple sum.
All good fortune,

IIRC the number was 41 for CC. We presented quotes from highly experienced recording professionals, Les Watt was a designer for Shure and EV and Harvey Gerst goes back for ages. These are not just opinions on what someone "likes". Read all the input, it looks like 2 against 100.
Thank you John
Neither your post I had linked to, nor the book quote, nor my intention has anything to do with localization but with music onset rise time.
The Black Hole......
I don’t know what makes you turn to localization issues. Most probably a misunderstanding. Apologies if I started it. No need for you to come back to it.

I think the interference between the sines, giving a changed envelop is seen as modulation.

Well its not, its still 2 and only 2 sines. The envelope doesnt change. More like beating than modulation.
Exactly, a guitar that is hardley plucked still sounds like it comes from the same direction as one thats played with a lot of attack.
Yes, to clarify, I'm not saying it's modulation. But the beat might look like that.

If you want to be practical look at the waveforms of musical instruments you think have an attack that will violate nyquist. Good luck finding one. Hint, its electronic. Physical systems have to overcome momentum.
