Hi,
I'm looking into Accurate and Dirac.
Is there a basic difference of where Dirac uses an approach to measure and correct for multiple spaces in a room because as they put it, "a perfect correction in one single point most always implies degradation everywhere else." And Acourate focuses on one ideal listening position.
Does the Dirac multi position approach produce a more even, and compromised, response? Does the Accurate approach produce a more ideal single listening position at a greater compromise to the rest of the room?
This specifically could apply to my room, I think, because it is a large workspace where I'm moving around a lot.
I do not know where to direct you for further reading, but the single point vs. spatially averaged, multipoint measurement debates have been quietly festering for awhile. I am strongly in the multipoint camp.
My understanding is that acoustic measurements of any kind will vary bigly at various points around the room. This is inevitable in room acoustics. You cannot measure every point in the room. The best you can do is to sample the sound field at various points, and combine those points with a "smart" weighted average, not a simple arithmetic average.
I think multipoint can give a truer picture for a larger area vs. the single point sample size = one. Every individual measurement in a room will have some purely local response issues at that point plus general and common room response issues. General room response issues can better be revealed via multipoint sampling with smart averaging techniques, since the multiple points are compared, weighted and combined. Via single point, general and local response issues are indistinguishable.
Understand also that it adds considerably to cost, complexity, etc. for the makers of room correction suites to use multipoint vs. single point. The makers who do use it have done considerable research, and they have concluded the added cost and complexity yield greater accuracy and better results for users. If not, they would have every incentive to simplify via single point.
Meanwhile, I really like Dirac and its ease of learning/use is extraordinarily good. It also sounds great to me. It is indispensable. I used Audyssey XT/32 w. Audyssey Pro prior to that.
