"Official" Audyssey thread (FAQ in post #1) - Page 1188

markus767, is this a couch shown on the measuring diagram? How big is it? Is it possible that it acts as a bass trap and the mic is not getting the bass properly because of that?

I had honestly forgotten that the ACM-1 had gold plugs It's been 3 years since the last ACM-1 was made so it wasn't something we keep seeing every day.

Whoops! Well, I'm just glad that we finally have this straightened out and can rest assured that most of us have the correct mic even though some of the boxes are mislabeled.

Thanks for all your investigative efforts and the free mic that Onkyo sent me yesterday.

I now have 3 mic's so it could be possible that one of them would give you a more pleasing calibration considering the slight variance in the manufacturing tolerances, right?

And do you think that it's a good idea for those that do a lot of tests, to reset the AVR to clear out the memory, so it's not overly fuzzy?

A Denon model but don't recall the model number; an Onkyo 885 and now the Integra 80.2.

Were your (after) measurements from a single position or were they averaged over some number of positions?

Markus....

what processor are you testing...is it a 4311?

Does the processor you are using allow you to look at what it thinks the result eq is after calibrating audyssey? If yes, does it show correction being applied?

Graphs look very strange.....

As others have said, there could be numerous reasons - mic positioning comes readily to mind.

But what I think it really shows is how useless subjective assessments of sound are, especially when made with quite long time periods between assessments, as is necessary with Audyssey because of the protracted setup procedure.

Time and again, objective critics, such as www.theaudiocritic.com, have proved that unless you can level match to +/- 0.5dB and double blind test, objective assessments show that people can't tell the difference between systems using different amplifiers for example. If that is the case then it's not surprising that people 'remember' their sound differently when they rerun the Audyssey setup using the SAME mic more than once, as appears to have happened here. If the volume is a dB or two different (or the mic placements were different), then the sound will be perceived as different, and in many cases as "better" or "worse" (usually more SPL is perceived as "better"). Also, there is some psychology coming into play where some people may have genuinely believed that they were using a "superior" (correctly calibrated) mic or an "inferior" (wrongly calibrated) mic and this belief may have deceived them into "hearing a difference" that is in line with their prejudices.

Unless anyone believes that there is some sort of conspiracy going on, or that people are deliberately being economical with the truth for commercial reasons ( and I would 100% discount Chris from Audyssey from that as my belief and understanding is that he is a person of unimpeachable integrity, which belief has been reinforced by his actions since this whole issue came up) then it seems to me that this matter is effectively closed. Onkyo users had the correct mic all the time (other than the few who had *defective* mics, which is a different issue entirely) and any perceived differences after running Audyssey with two different, but both correct, mics can be attributed to the reasons above.

Just my two penn'orth as we say in England

Kind Regards,

And I always thought it was a tuppence.

Just don't start singing the chimney sweep song . . . or the feed the birds song, and everything'll be okay

Anybody with the Pro software having problems loading measurements onto the Audyssey website?The measurement file loads up real slow and then just stops and eventually Google gives me a time out error.It's been happening to me for the last 2 days.

Just wondering if it's just on my end or if anybody else has had this issue.

Markus, just to clarify, were these full-range measures of the Left/Right as Large/Full-range? Or did they include the sub?

If they were of the front speakers as full-range, that would explain much of what you see. I know when I upgraded to a MultEQ XT receiver with pre-outs, I found that Audyssey only had enough filter capacity to do very broad changes in the front speakers at the lower frequencies, say below 300Hz. The MultEQ version in your TX-NR708 has even fewer filters. This is one reason for the excitement around MultEQ XT32, but I've not yet seen anyone's room measurements comparing an XT32 receiver with an earlier Audyssey-enabled model.

If the mic gods align with your preference, then yes...

mine was NO placebo effect that ACM1 mic borked both my 707 & 807 AVR's settings even the Wife could tell the difference ... But I have the Correct mic's now & I'm happy
Thank You Chris !

Let me get this straight: you are actually thanking me for making your wife happy I don't know if I'm comfortable with that

Hey, it's Friday....

She's in Menopause Soo Anything OR Anyone who makes her happy makes me happy !

TMI I'm sorry I said anything

Guys,

how is the level in dB of each speaker determined by Audissey? Is it calculated based on the aveage response across pre-established frequency ranges or just one specific frequency?

Thanks

hey,
i her give a Hard Time about the Phase all the time soooo It's Cool !

Looking forward to getting my 5008 & XT32 ... can't wait !
couldn't wait on the Outlaw

Well, I would presume that your speaker should be approaching a flat in-room response after running Audyssey, so it shouldn't matter (much) at which part of the spectrum the it measures as they should all be about the same...

Chris, would you care to share any specifics or guidance on Dynamic Volume? In particular I'm curious about the targeted dynamic range for each setting (light, medium, heavy).

The light setting is a bit aggressive for my tastes, and I briefly switched to heavy but didn't really hear much of a difference, so it got me curious.

Light does the least dynamic range containing--I wouldn't think it would be aggressive at all. You may not hear it on most content except for the very loud. Heavy is the most extreme and is intended for late night listening. In all settings, it uses dialog as the reference. Set the volume where you want normal dialog to be and then it makes sure that nothing gets too loud or too soft.

Chris I saw you mention high humidity damaging the mic. I live in louisiana, what do I need to do.

I hear Phoenix is pretty dry . I didn't mean humidity in your house. More like a mic that got wet accidentally. It was just speculation to try to interpret the symptoms: excessively rolled off high frequency response in the mic

Thank you Chris for investigating and solving the issue of Onkyo mics!

I sent an e-mail to Onkyo USA about 4 days ago and they sent a new mic via FedEx up to Canada already! Guess I didn't need the mic after all, but I think I will try it. Overall very happy with my 906 and the results after Audyssey calibration.

Thanks again for your time and effort to solve this mystery!
