" (hopefully we can find a less awkward title).
Perhaps I have too much time on my hands?
No, you're just very thorough:). And whether it belongs in a Pro FAQ as such, it's something that should be addressed as a team because we may have divergent opinions about where this might go. In your own words, we're in "uncharted waters" IIRC;).
To your point: my initial thought was that addressing post-calibration results assessment/adjustment, while not strictly related to Pro per se, is something that is a) more advanced than the average consumer Audyssey calibrator may be familiar with, particularly someone coming from an older Audyssey and/or non-Audssey AVR and b) a logical "next step" on the learning curve for the user seeking to optmize their system.
Not only does Pro offer up to 32 measurement positions, but the Target Curve Editor, choice of crossovers, save/load of measurements (imperfect as it is, as we know, WRT subs), choice of mid-range compensation curves etc. are part of the package. A user looking for those features is much more likely to want to further tweak their system than a "set and forget" person working with the conventional/consumer Audyssey release. Hence an "advanced" FAQ is a more appropriate place to have a pre/post-calibration optimization and assessment thread than an FAQ that's a "how to" for someone learning how to use Audyssey in the first place.
And by tweaking, I mean a combination of Target Curve editing, distance/delay/phase adjustments at the crossover/splice region, exploration of crossovers, repositioning of speakers, all accompanied by remeasurement as as I think we can agree that the "After" Audyssey charts are too coarse at 1/6 smoothing to be useful.
Hence having a flow chart of how to proceed, and understanding the issues involved in using a particular level of smoothing, is essential for the learning using Pro.
Also, I was thinking of my own experience in the past four months. Once ccotenj pushed me into the measurement rabbithole
, I found myself going through at least four different threads (here, Audyssey, OmniMic, and the 4311) to wrap my head around the most rigorous way to "trust but verify". Frankly, I would have been lost without Keith's trek in finding his phase issue to point the way. So collect another debt of thanks, Keith:D
Thinking about what speakers & sub combination to test, distance and/or phase adustments, what smoothing level, the kind of pseudo-noise signals and channels to use, and what AVR surround setting (I originally used Multichannel Stereo and PLII Music because I thought they were most appropriate for my listening, before I realized that Stereo and in some cases PLII Cinema were better options) took many hours that would have been shortened if we had a comprehensive assessment FAQ. I hope that others here, as well as newbies coming to the Pro thread as the 4520 and newer AVRs hit the market, could make use of it as well.
That's a long winded way of saying that not everyone has the level of intuition and experience, hence it has value...but regardless of whether we do it now or in the future, I'm glad we can at least put it on the agenda.
