Thank you very much for your excellent PRIRs and documentations, I think you are an experienced "PRIR hunter"!!!!
I've placed some of your PRIRs as impulse responses into SVS Demo folder (foobar instructions in process), they works good for me in mainstream and classic music, too.
!!! I've quickly checked out your last posted PRIRs from Ivan's House, they have a big correlation problem: center and sub are good (coefficient 0,5 -0,9) , the other speakers are out of phase / opposite in phase.
A comparison with all other aligned dropbox PRIRs in my daw shows correlation coefficients in the range of 0,5 - 0,9, which is normal with room reflections.
Please try this with Ivan's House / and other PRIRs:
a) With pink noise and all channels on the center position must ever located in front - use MODE (2x). Works with nearly all PRIRs, especially ITU sets like MSM.
b) MODE: L and R on (virtual center) center position between L/R must be stable in the middle and than add C, the front localisation should be improved.
In a) and b) center position in Ivan's House is out of phase ... no front localisation is possible.
Please give me the distance between head and speakers at PRIR mesurement and the room dimensions of Ivan's House. The correlation problem could be a standing wave situation. I try to figure out this in my daw changing phase alignment of surround speakers. Nevertheless the Triad speakers sounds very good ...
Bye for now!
