Active Room Treatment (ART) by Dirac

[ban25]

Sorry, I have a possibly silly question. One major difference between StormAudio and D&M regarding ART is that StormAudio allows detailed PEQ adjustments before using ART. If I'm using a subwoofer that supports PEQ adjustments via its app—such as SVS, Perlisten, MK Sound, etc.—can I achieve the same result?

In other words, can I use REW together with the subwoofer's app to adjust the PEQ and flatten the low-frequency response curve before running Dirac?

I wouldn't do it. In that case your sub has to convert the input signal back to digital, apply DSP, and go back through its own DAC before playing the signal. All those steps add several ms of latency, which Dirac then has to counter by delaying all other speakers in your system in order to properly time-align. That pushes your video further out of sync with the audio, all for no actual benefit since Dirac is already more capable of EQ'ing the bass region than whatever your sub has built-in.

As a rule, I avoid subwoofers or other active speakers with on-board DSP, especially if it cannot be defeated.

I don’t know if it can reach yet 300hz but i remember to have read it somewhere

Right now it is 150hz for ART. When it was in beta it was up to 300hz. I think Dirac was worried about audibility of the cancellation signals going over 150hz. At least that is what I recall.

Since ART for Denon / Marantz is around the corner, I'm attaching this in case you missed it...

Agreed.

However, it really depends on the subs. SVS and Arendals already apply DSP by default (port tuning mode), and one would need to measure what additional DSP processing does. When I reverse the phase on Arendals that are in the back of the room, it does not cost any DSP delay beyond the usual.

I am not Dirac expert by any means, but know that in general Audy will try to fix 10dB difference between peaks and dips - is there any general rule what Dirac would do?

I previously was running just Wharfedale Evo 4.3 and a single Rythmik F12 at the side wall. I just went for a pair of RSL Speedwoofer 10E. I think that these will do nicely in a support role. I had also considered a pair of Rythmik FM8 dual 8" subs, which can also play midbass well but the price was just too much for me. How are other people thinking about the hardware side of things?

2025 CEDIA Shares: Dirac - Residential Systems

Dirac gives Residential Systems readers a sneak peek at what the company is planning for its CEDIA Expo/CIX 2025 exhibit.

www.residentialsystems.com

Highlight quotes:
"With Dirac Live Active Room Treatment (ART) now expanding to Denon and Marantz devices — with more coming this fall."

D&M confirmed, also Hyperion (elsewhere not in this interview), and "more coming this fall"

Also:
"the latest evolution of Dirac Live ART. Now featuring more accurate measurements and a redesigned UX for full in-app calibration"

This confirms my long held suspicion the the User Interface was receiving a makeover, which may be the reason for the delay in ART release.... it needed to be more user friendly!

Great news. I wonder though what "more accurate measurements" means? While there is always room for improvement, does that mean that previously it was not that accurate (and potentially across other Dirac products)?

Does it? I sure hope so, but I wonder if "app" is just the Dirac phone app, not the PC/Mac program.

Imo, that's just another one of the many marketing hypes offered by manufacturers of all sorts, not much different than the hypes of other things like Audyssey's cheap mic vs the Audyssey's so called individually calibrated mics, minidsp's umik-1 vs umik-2, the much more expensive ones don't really make a meaningful difference but because manufactures make their claims about better accuracy that is very much a relative term and subject to bottleneck logics, some, or many users would buy in to the claims and even heard (they thought, that is..) better results because of the "more accurate mics", so go figure..

I guess we will find out in the next week...

As usual, you are probably right . Given that they are marketing guys, probably should have used less controversial language such as "further improved accuracy of the measurements" as their language could be interpreted that previous measurements were not that accurate.

Guilty of owning calibrated Audy mic, but given the relatively low price it was worth it to have a peace of mind. Not that I can tell any difference of course. One mic I would like to have though is that Trinnov fancy one. Perhaps one day when the Hell Freezes Over...

No real news from Cedia. Only Dolby Vision 2 that makes our actual gear obsolete

Yeah I think we're looking at November. They said "near the end of the year". They'll release the license in time for the Christmas spending rush to move the gear and get some activations. Unfortunate. Unless someone else here has heard something? Would be great if anyone had any real insight.

I’m confused, AudioControl seems to only have discontinued AV ‘s (at least the line up ion their website) why are they bringing the ART to their products?

 

[Kal Rubinson]

They have a new line, Hyperion: https://www.avproglobal.com/pages/hyperion

Looks good, hope its a good price point.

Cant find a PDF or specs anywere.

APR-16 will be $7,995 USD apparently
