I realize that the min-phase operation produces a phase aligned result that is exported from CL4 - what I'm asking though is, when the CL4 min-phase alignment process is executed, does it reverse any manual de-alignment I may have intentionally created in my CL4 mix (ie if I moved one mic forward x mm using the CL4 "Align" function..)
My understanding is that this processing only applies, to the result of the Mix of the 4 Mixer slots of cab lab4: .syx/.ir which we want to save.
I don't see why the alignment between each Mixer slot would not be preserved when saving
the Mix, since Min Phase is not applied to each Mixer slot (as we could do in Cab-Lab3) but only to the final Mix,
But I could be wrong
Understood - but the question is the reverse, does Min Phase Transformation also remove superfluous data from the beginning of the exported IR?
Min Phase ensures that all IRs are time aligned,
and Auto Trim removes superfluous data from the beginning of the IR
As I understand it, as long as you do not use Auto trim, nothing is removed,
Min phase ensuring "phase consistency" with files (.syx / .ir) that have undergone the same processing.
I understand the specifics of the different resolutions, what I'm asking is does the CL4 "Ultrares" vs "Normal" export option actually affect the resolution of exported .syx file depending on which option you choose?
from FAS :
UltraRes™ processing is a Fractal Audio
proprietary technique
which enhances the spectral
resolution of an IR without adding CPU burden or storage
requirements.
UltraRes IRs are more detailed than Standard
resolution IRs.
Maybe, this work a bit like the "IR Length" parameter in the Cab Block > Cab More ...or you have the choice between: 256, 512,1024, 2048 or more... shorter IR = less information, less resolution + probably some old Chinese secrets
?
In my humble opinion, only FAS can answer this in detail.
But Honestly, regarding this type of problem, it is the ears that must decide
I tried exporting in both and then comparing in Axfx: they looked the same in the Axfx Cab block (zoomed out at align page with both IRs loaded) whether exported in "Ultrares" or "Normal" .)
Yes, but if you change the "IR Length" parameter in the Cab Block > Cab More page,
Normally going from 256 to 2048 we should see a difference in the Align page?
I don't think Align page is the best tool to see this sort of things
I'm clear that a .IR file can be imported to CL4 and not .syx. My question is what the .IR file being produced or not has to do with the output option title wording which asks if the user wants "Ultrares" or "Normal"? Imo this is two different things: 1. Do I want a .ir file created in order to be able to import my mix (whether Ultrares or StandardRes) back into CL4, and 2. Do I want my generated result (.syx) to be Ultrasres or Standard (Normal?) resolution. ... Confusing.
I don't know why it's like that, but I've gotten used to it,
Anyway, we have no choice : FAS design !
These are just my 2cents, I’m not by any means an Expert 8)
