Dirac ART is now running on beta FW for Denon Xx800H AVRs!
- Thread starter PHD
- Start date
Have you checked if Dirac logs shows any errors? They are pretty technical, but just in case there is something. Search for lines with warning or error. In Windows they are located username/Dirac/logs/
Thank you, will check it tomorrow
Where are the logs found? I don't have problems now, fingers crossed, but it would be useful to know.
Subtraction is a subset of addition...
After couple of days with ART can say that I am really pleased with the performance. More to tweak but this is already looking pretty good (at least to me). Current ART setup for my 9.4.4 system is to support subs with all bed channels (8 - sans center) as they can dig to 30-50hz range. LR and C (C separate group) also get support from FW and SLR. Surrounds also get support from FW. Subs support all groups, and other groups (back surrounds, and Atmos front and back) are pairs that only support each other as no more filters to spare. There is sub shelf of +7dB and +5dB on the rest of the speakers. I started custom curves but not yet there - hopefully they will iron out the remaining issues. A note is that ART is rolling off the bed channels relatively conservatively. There is more that can be squeezed out of them based on my Audy experience. Will try to remedy that with custom curves.
One should bear in mind that in my multi-purpose living/dining/kitchen/hallways room (see floor plan, room on the top of the image), decay will not be able to match closed rectangular rooms. Also, the space is relatively large (10,000 sq ft+) so by its own creates reverbs. On the bright side, the speakers are relatively close (2.5m or less) so I would say that psycho-acoustic perception might be different than what omni-directional mic records. FQ response also needs some more work that custom curves will hopefully provide.
I am facing some REW issues with new Mac - for example RT60 and Waterfall graphs turn out inaccurate, but these two seem correct as far as I can tell. My FW's are not in the graph as obviously REW does only 7.1, but they are similar to SLR.
EDIT: Was sweeping LFE to 20hz by mistake, but not much more to be had after that, my subs fall like a rock for the most part as ART does not seem to care about some 15hz potential that 2 out of 4 subs have.
EDIT 2: Minor point - Surrounds and Back Surrounds should be the other way around. Back surrounds do better as have wall support. Another thing to fix in next REW run.

Understand, I didn't get that fact. Then it's clear, you need to take parts of your ear into account.
Problem is our ears are pretty different in this frequency range ... but the whole idea is interesting, would like to hear such a calibration.
It's been months since I last measured RT60 on my system, before ART. And DLBC had issues in the bass region, with high delay values.
To confirm, RT60 is the light blue dotted line at the bottom, hovering barely above 0? If that's the case, it seems awesome.
Waiting for my fourth sub to arrive before remeasuring. SVS are taking their own sweet time...
RT 60 would be a separate chart - this is spectrogram.
Not sure what is going on with REW on Mac - had to remap the C and LFE channels and also should remap the surrounds and back surrounds as the above sweep did not capture it right (reversed). Both waterfall and RT60 charts don't make any sense. Tried couple of REW versions but seems like none of them work perfectly. This was 5.40 beta 102 that seemed to do the best job.
Might at one point do the check with Windows laptop, but not feeling it right now as have to set it up from scratch. These two graphs give me enough to move on with optimization - in due time.

The math is always additive, the effect may not be.
Sitting with it right now
The log sees that my volume on receiver is -25.5dB
And Dirac software says -55.5dB
This might be something
Master gain in this case is the receiver value
duff_dev_set_speaker_gain (device -55.5) is the vaule Dirac software has
*edit*
Have done a reset several time.
Also when i press "proceed to measurement levels" the GUI starts and i have to press "back" on the remote to close the GUI. (known bugg? )

Latest.
Problem solved
I have used a Nuc for years as a Pc connected via hdmi to different receivers / Minidsp:s for Dirac.
And Hdmi out to screen.
With Cinema 50 i cant do it that way.
Nuc to screen - connection via wifi to receiver and usb mic in the receiver instead of Nuc
Then all the volume adjustments works in the software.
If i had a laptop instead i would never seen this issue.

Strange. I have an HTPC (Nvidia card) connected to receiver, connected to screen and never had a problem, with Umik microphone connected to the aforementioned HTPC.
Yes it is but it works and i am happy
Have been living with ART since the launch with my 5.1.4 set up. Arendal 1723s towers and the 1s subwoofer and must say that the bass is so good that I'm not wanting for anything. It is tight, punchy and enveloping. Was planning on adding another 1s somewhere in the future but dont think I need it anymore. It's that good.
As someone who has two 1S subs (and two SVS SB13U), I say do it
They are great subs and going dual is one of the most substantial HT upgrades I have done, especially now with these highly sophisticated RC-systems, which can make great use out of more subwoofers.Can you describe what makes you say the upgrade was so substantial? Just because the upgrade to ART is already so big, much more impact of the bass, all the detail of the bass is there and it is super tight. So don't know what I would need aside from that?!As someone who has two 1S subs (and two SVS SB13U), I say do it
Well pretty much what everybody is reporting when they buy a second sub
Going dual did a few different things for me, mostly what everybody tells you; smoother frequency response, more headroom (= more deep bass output and less distortion), less localisation (the bass feels more like it's coming from "all around") and the biggest thing for me: more sense of pressure at lower volumes (this increased even more with a third and a fourth sub).Cool, I am REALLY interested to test this with ART:rting when they buy a second sub
1 Sub and two decent towers, vs 2 subs and the same towers. Also because some people in this threath report that the bass with ART is anchored to the front stage, so all around you might change then? And the smoothness and impact has already improved SO MUCH in my set up.
In the end I'll prob test this myself as it can easily be done with the 60 days trial from Arendal... Let's see how long it will take me to scratch that itch.... Hahaha...
