None. Aliasing noise is broadband.Cliff, how much we can reduce Alias (Fizz) with Post EQ-ing such as high cut filter or reducing it by turning down high cut parameter in cab-block?

Wanted to see if U caught that. Nice name on the original file you posted .
The issue of aliasing within amp modelers doesn't happen at track sample rate (e.g. input 48 kHz vs. 192 kHz), but within the amp modeling. So it would depend on whether Helix Native plugin's amp models over-samples more than the hardware Helix unit.One nice thing with the Helix Native plugin is you can force over-sample in your DAW by mixing down the guitar tracks in a higher sample rate; this would likely help reduce the aliasing. Although, I still believe the Axe-FX oversamples even further (8 or 16x I think?).
Is it (in theory) possible to get rid of aliasing altogether? Or would this result in a singularity of processing power?

Actually it can be argued that the sampling rate is some very high, finite value equal to the quantum time interval (in theory time is not continuous but quantized like everything else in the universe).

Ok 32x, in case it is the right value, is way beyond what todays hardware is capable, at least for low latency systems where multicores are to be avoided. So basically the better alias performance of the III compared to the II is based on the superior processing power? Or is it based on better code? If so, can it be ported to the II? I'm not saying you have to or should, but is there room for improvement for the II?A high enough oversampling rate would effectively reduce the aliasing to where it's below the thermal noise. I'm too tired do the math right now on what rate would be required but it's probably at least 32x. Of course that brings a whole host of new problems. The CPU usage would double, filter instabilities would likely occur, etc., etc.
The quantization of things in the universe is based on a theory, but very well proven by experiments! Quantum theory is probably the best proven theory in physics. In this case one could say that analog amps also alias, but it's beyond any measureability.Analog circuits are analogous to a digital circuit with infinite sampling rate. Actually it can be argued that the sampling rate is some very high, finite value equal to the quantum time interval (in theory time is not continuous but quantized like everything else in the universe).

Seeing this movie whenfirst theatrically released in 70mm Cinerama was a seminal event in my psychedelic youth.
