Is this what it is doing? I just ran Audyssey for the first time a few days ago and it swept each speaker 10 times for every measurement. They all seemed to be the same volume to me and not all that loud.
Josh, when I reran the Audyssey setup this weekend, it behaved identically to what you wrote. There were 10 whoops for each speaker. These are repeated at progressively louder volumes if the Audyssey mic does not hear the sound cleanly enough; that might be where the 3 comes in.

Re: Audyssey Graphs - Please post your results!

Thanks Bill.

I was sort of hoping that Moonfly was right and that Audyssey was at least doing something to check the output capabilities, but it appears that is not the case. I could see real subwoofer overload problems with a lot of systems with the amount of low end boosting that Audyssey ends up doing in practice.

I've just sent an e-mail to Chris Kyriakakis of Audyssey to get some clarification in this. Hopefully we'll get a definite answer back soon. I'll post up any info I get.

Hi Dan,
There is no headroom testing. If the sequence of 10 chirps is repeating louder then it means that the mic did not receive enough signal to noise ratio.
What is the exact error message you are getting on the DIY sub?
Best regards,
Chris Kyriakakis
CTO, Audyssey

That should clear that up. Not sure where I got the headroom testing thing from. Another eq device somewhere maybe.

I understand the concern. +9dB of eq boost and then adding DynEQ boost to that at lower volume settings adds up. I was fortunate to choose a sub that offers some options on tuning and setting the subsonic filter, so after experimenting I found a good combination.

I remember Chris writing once in the Audyssey thread that he was aware that the current algorithm could cause problems on some subs, and they were looking at what could be done in a future release.

Re: Audyssey Graphs - Please post your results!

Here are a couple of graphs I took from mine this morning, I may relocate my subs back to their normal postition but I figured since I had some time yesterday I would move em and see what happens.

Using SPL/UCA202, TX-NR1007, ASEQ-1, PBU x2



Full sweep, red is no audyssey and no ASEQ. Blue is with MultEQ-XT & ASEQ






Blue is no MultEQ-XT or ASEQ, Purple is MultEQ-XT only, Teal is MultEQ-XT & ASEQ

Re: Audyssey Graphs - Please post your results!

Nice and smooth, but pretty hot? Looks like around 12dB up from the rest?
Are you using DynamicEQ?

Re: Audyssey Graphs - Please post your results!

yes, I am. I just recieved the NR1007 about 2 weeks ago and this is my first amp with Audyssey so I really have no idea what I'm doing. I only set up 6 mic positions for the MultEQ and used the same six for the ASEQ. The graphs that say no audyssey are actually with the Dynamic Eq turned off, I ran sweeps with the THX volume on an off and really didnt see much of a difference at all.

Please excuse my typing for I have twin 2 year old girls and one of them managed to spill lemon aid on my keyboard and some of my keys stick mainly the shift button.

Re: Audyssey Graphs - Please post your results!

What I am seeing is Audyssey seems to do pretty well on the bass, but nothing special on the highs.

Thanks for all the graphs... I would like to see more...
