Man, the problem seems to be, false notions or not, that you set out to insult someone who has made an honest attempt at demystifying a plug.

Your knowledge is appreciated, unlike your manners.
Sorry for having been harsh to your feelings, please show me my supposed insults. And, you know, even if I like people, I'm not in search of a fan club. So, straigth language doesn't disturb me. Falses notions irritate me a lot, I know I'm not perfect. And my english is not as refined as I would like it to be.


Anyway, Hubird has now pointed what is the core and most important in the PsyQ, by this quote:
(...) controlled changes of the phase relationships of the high frequencies and harmonics.

This partial information (pedant and rather obscure) can be simplified and completed by: "aligning harmonics" on the fundamentals, by the way of controlled phase shifts (or "phase rotations", as I used this term perhaps too quickly and badly translated from the french technical laguage).


This means that existing relative high harmonics (and high frequencies partials) in the original sound are temporally advanced to be temporally aligned with the fundamentals lower frequencies in the sound. Then, instruments fundamentals and harmonics start coarsely "in the same time", unlike as with the original sound that has been corrected, and our ears like it very much (as our ears don't like very much when high frequencies harmonics and partials come too late relatively to the fundamentals: it sounds "dull"). Without intellectualy understanding the process, our ears and brain can feel and determine what are the good settings for this correction.

Hey Grok, first check out part of hubird's first post on the subject:

"The Mid/High doesn't change the 'spectral content' of the audio, it doesn't really changes the objective loudness of frequencies, the process is much more subtle, and is based on 'amplitude-depending phase shifting', whatever that may be."

I can kind of understand your english not being good enough, but it should at least have reached the point where you can equate "phase rotation" and "phase shifting" as being pretty much the exact same thing, otherwise I'm really not sure why you would want to waste time interacting on english-based audio forums.

Secondly, about your "supposed insults", you might be happy to learn that

"What a great load of pedantic bullsh*t! You have understood nothing!"

isn't usually perceived in a well-meaning manner by both native and non-native english speaking individuals and collectives around and withing the world. There are far more diplomatic and friendly ways to correct someone's assertions if you find them to be wrong, incomplete, or "pedant and rather obscure" (c'est probablement juste ton anglais, parce que moi j'avais bien compris.)

But hey, don't worry mon poussin, si tu patauges assez fort, petit tétard deviendra grand =P.
