Active Room Treatment (ART) by Dirac
- Thread starter Flak
- Start date
Or floor firing subs?
Last I heard: not recommended.
Edit: My comment was for the basic Dirac RC. Not sure about ART but basic Dirac RC is not abandoned in the least!
It’s probably supported, or at least it seems possible.
Can I use ATMOS with Dirac? What about upfiring speakers vs ceiling speakers? | Dirac Live
ATMOS: Upfiring speakers vs ceiling speakersUpfiring speakers behave differently than ceiling speakers in Dirac Live (if they have been properly labeled in the device).The speaker type should be "DOLBY_ATMOS_SPEAKER" for upfiring speakers. This should trigger a pre-emphasis filter being applied...
Yes.
Is Dirac Live able to correct dipole speakers? | Dirac Live Room Correction Suite (Processor)
Yes.
For up-firing (from Dirac):It’s probably supported, or at least it seems possible.

Yes.
Is Dirac Live able to correct dipole speakers? | Dirac Live Room Correction Suite (Processor)
Yes.
There are two caveats, though:
- This functionality is not tested in our device certification.
- Dirac Live does not properly align the delay of the reflected (intended) wave as it instead aligns the direct wave.
The above doesn't exactly give me the "warm and fuzzies" for up-firing support!

I use upfiring speakers and judging by the distance, Dirac actually picks up on the ceiling reflection, not the direct wave (upwards firing speakers are located behind the TV, out of line of sight, and my ceiling is fairly low).
Having said that, I do not correct them with Dirac (not beyond overcoming the low end proximity gain), given the reflected response does not correlate to the direct response. It's a compromised solution anyway, I don't think accuracy is that important, so long as it provides the effect.
EDIT:
Though now that I think about it, could be there is a set time delay automatically added to any Atmos Enabled speaker. It doesn't seem show on the speaker menu when using Dirac, but I recall having seen the option somewhere prior (with a non-zero minimum default).

The measurements are quite unambivalent - ART achieves things that otherwise can only be achieved through architectural design of a dedicated listening, and/or through extensive room treatment, which is often completely impractical for many of us.
ART shows that it is possible to electronically improve decay time in the room, and by eliminating a large part of that reflected sound overhang, improve the clarity of our system.
It certainly isn't cheap, but the type and level of improvement that it provides would otherwise cost multiple times that amount, so if you value that improvement, it is fantastic value. People spend tens of thousands on acoustic treatments, bass traps, constructing dedicated listening / theatre rooms - and that level of improvement can potentially be achieved for $600... while keeping the setup in your shared purpose living space.
How difficult is it to use? Do you need expertise or is it straight forward like ARC Genesis?
I found the base Dirac Live to be easy to use and setup.
It has a plethora of options and manual settings alternatives... so once you start experimenting, you can mess it up!
When I first got my Integra DRX3.4 with Dirac Live included, I got it up and running within minutes, using the "quick" smartphone app setup alternative, and had it tuned/calibrated and playing music in about 20minutes - using the 3 mic position option.
I believe according to reports by those who recently installed ART, that those who followed a similar "quick / default" path, had no trouble, and had it up and running quickly and with no fuss.
However, the plethora of tuning options is a never ending source of temptation - yes, you can often eke out performance improvements over and above the base defaults.... and these can be worthwhile, as all our systems and rooms are different!
But once you go down the rabbit hole, you can lose hours, days, in analysis, experimentation, and failed configurations that may degrade rather than improve the sound...
So like anything that is infinitely tunable... it is easy to get it wrong too.
Having said that, a number of guides are starting to turn up in the forums, with people's recommendations showing what worked for them and documenting processes that can be followed.
I intend to jump on the ART bandwagon shortly...
If your AVR supports ART, I strongly recommend giving it a try.
Even if you don’t end up liking it, you can get a refund, so there’s no real risk.
Denon AVR-X3800H Review
Its the other way round. The AVR did the measurements - this was transferred to REW via Audacity as part of the ADY file from the app, and the filters were created in REW. The script then generated a new ADY file from the filters for the app to transfer back to the AVR. Thanks again, so either...

The setup isn’t very difficult, but if you get stuck, just ask me.

As for the preparation steps:
Create a Dirac account, and after purchasing the license, copy the activation code from the e-mail and activate it by logging into your account.
Install the Dirac software and log in.
The recommended measurement microphone is the UMIK-1.
Prepare the calibration file for it.
After that, just follow the manual and you should be fine.
This information is very helpful. Thank you for sharing. BTW. I pulled the trigger on the X3800H and the Dirac ART bundle. So I'll start playing with ART sometime next week.If your AVR supports ART, I strongly recommend giving it a try.

You can but it's really unnecessary. Some have even said it may be too sensitive a mic to use for Dirac!

AI that could do what exactly? No, I’m not optimistic about that. I don’t see a way to cut out very deliberate and intentional filter design & maths. Perhaps AI could have a place in guiding the user through setup, but the engine itself is the culmination of years of research. I don’t think it’s going anywhere.
Ok thanks. I'm going to order a UMIK-1 just in case.
Both will work, one upside with umik 2 is that you can sweep at higher volume without changing the sensitivty on mic and cal file
I have never heard of any issues with umik 2
The sensitivity issues for the UMIK2 were reported at AVS.
I don't think you lose anything going with UMIK1 since it's the gold standard and what REW and Dirac were tested on (I think).
