It would be awesome to have it in Cab-Lab
You don't listen to a guitar speaker with your ear against the grill cloth.
Spatial Variability. That's the vibroacoustic term at least for the difference in measurements between several pressure transducers or accelerometers. Sound engineers may call it something else. Coherence is the the measurement of how in phase different locations are to the same wave among other things.Yeah you are correct. Doppler shift is frequency change due to movement of the source.
What's the term for the phenomenon caused by change in position of the observer...?
This is probably the single greatest answer ever given on this forum.
It might be the single most important parameter for me in the Axe.
So, 0.00 dephase is on and 10.00 is 180 degrees out?

Already in progress.
It's totally up to the user to decide. It smoothes the peaks and valleys in the IR, too smooth loses its character, but a little bit improves clarity. So, tweak to taste. The "phase" word is perhaps a bit misleading since it doesn't affect phase in that "in-out/0-180'" way at all.Yeah, can someone advise what should be the ideal setting (0 to 10) be like for this cool feature? Really curious how are the other Axe users dialling it in. Thanks....
there isn't "ideal". I've used values as low as 0.5 up to high as 6. on some IRs I don't use it at all. depends on how the original IR sounds and what tone you're after...Yeah, can someone advise what should be the ideal setting (0 to 10) be like for this cool feature?

But, isn't it pretty fair to say that most of the greatest guitar tones were recorded this way. I have certainly recorded guitar with an sm57 right in front of a cab and gotten a great recorded tone; and the essential recorded tone sounded pretty much the same as the amp in the room. So it would seem that the sound being generated at that point is an acceptable sound.
Good question. The answer has to do with the imperfections that arise when you close-mic a speaker...If an IR is simply a capture of a cab mic'd up, what is going 'wrong' with the process that De-Phase becomes necessary?
The De-phase parameter corrects for the phase issues that occur whenever you close-mic a speaker cab, even if you're only using one mic.
Remember that a guitar speaker is essentially a chunk of hardware twelve inches across. Each point on the speaker generates sound. When your mic is close to the grill, sound from the speaker is coming at it from straight in front of the mic, from parts of the cone above the mic and below the mic, from the right and left sides...
All these parts of the speaker are at different distances from the mic. So the sound from each part arrives at the mic at different times, and that means they're out of phase with each other. The De-phase parameter reduces that out-of-phasiness and smooths out the response, making it sound more like your cab sounds when you're listening at a reasonable distance.
