Wenn etwas funktioniert, dann muss man es auch rezensieren. Und die App hat bei mir sehr gute Ergebnisse geliefert.
Useless
The app won’t let you do anything unless you have a recording device. I already have measurements and want to use the app to make tweaks to my profiles. Can’t open my project files, because it refuses to connect to my Marantz Cinema 30 due to a lack of a microphone. What a ridiculous limitation.
Take your ears up a notch
Using Dirac with my Onkyo RZ-50 was fairly easy. The Onkyo comes with Dirac. Keeping the iPad software connected wasn’t perfect but the end result was well worth a bit of aggravation. My set up is all custom in walls and ceiling speakers which sounded great, after using DIRAC the clarity bumped up to that next level.

Useless with Denon X3800H
As far as I can tell, this app does not work with Dirac on the Denon X3800H. Clearer compatibility information would save a lot of wasted time.
Excellent sound quality – but an inconsistent workflow
Let me describe the real-world experience step by step.
Step 1: Measurement
Using the iPhone app for measurement is, in my experience, practically unusable.
Connecting the measurement microphone is cumbersome, detection is unreliable, and the overall process feels unstable. For software in this price range, that is disappointing.
So the decision was to measure using my Mac instead.
That works — but only if the Mac is physically placed next to the amplifier.
In my case, measurement over the network was not reliable. This means: carry the Mac into the living room, set it up beside the amplifier, connect everything, and then run the measurements.
Once the Mac is positioned directly next to the unit, the process itself works well.
The microphone is recognized properly, measurement points are captured correctly, and the target curves can be calculated without issues. The resulting sound quality is excellent.
Up to this point: inconvenient, but technically solid.
⸻
Step 2: Fine-tuning — and this is where the real problem begins
After completing all measurements and calculations, you naturally want to fine-tune the target curve while listening — sitting comfortably on the sofa, making small adjustments.
That is exactly what a mobile app should be for.
However, when opening the app and trying to load the project, the second major issue appears.
The app does not provide access to projects created on the Mac.
The raw measurement data remains stored locally on the Mac.
The amplifier only stores the calculated filter — not the editable measurement data.
In practical terms:
• The app cannot edit projects created on the Mac.
• Without a connected microphone, the app blocks project access entirely.
• The amplifier does not allow retrieval of the original measurement curves.
The consequence:
Every small adjustment requires setting up the Mac next to the amplifier again.
⸻
Summary
Problem 1:
Measurement via the mobile app is not practically usable.
Problem 2:
If you measure properly using a Mac, mobile post-editing is effectively impossible.
You are forced to choose between an unreliable mobile measurement process or repeatedly rebuilding your Mac setup for minor adjustments.
For software in the ~$300 range, this is not a cohesive system.
⸻
Conclusion
Sound quality: Excellent
Measurement engine on Mac: Good
Overall workflow: Not well integrated
Dirac Live delivers outstanding acoustic results — but the overall system architecture feels incomplete and unnecessarily restrictive.

Not bad at all
Tricky to get correct for proper measurements but when it comes to elite systems it always is. Worth it. Gives an amazing baseline for tweaking.
Can’t find my equipment on iOS
It’s all in the title, useless app, don’t bother
“Low Noise Level.”
It won’t go past that! I cannot turn off anything else to lower the noise in my house for this to calibrate. I’ll never ever in my life purchase anything with Dirac Live. I should’ve bought an Anthem receiver!!
NAD C3050
Half baked app. Poor user interface, unresponsive to touch and very limited functionality. Running on latest IOS and latest version.
No more detection of Umik1 on ipadOS 26
Issues with microphone and ART license
Kills my Subwoofer on my NAD
It works fine except for the fact that it kills my external subwoofer on my NAD 3050C apparently this has been a known issue for a while but they still haven’t fixed it.
Total waste of my time
I just lost 3 hours of my time dealing with this useless app. Don’t loose your time and go straight to your device native system, like AccuEQ for Onkyo.
Ne fonctionne pas du tout sur iPhone 15 pro
Cette application ne fonctionne absolument pas sur mon iPhone 15 pro ios18.5. Mon Nad T758 est trouvé mais l’application n’arrive pas à se connecter dessus…
Impressively awful
All the smart people at Dirac got to work on the room correction. The apps, PC and IOS, got the less talented crew. Nothing but issues. Already bought a full sub. Activated it. PC app still wants me to buy a sub. IOS app can’t even find my Node Icon streamer. I’m not alone if audio forums & feedback are a guide.

Abolute rubbish
Tried this with my NAD C399, and it never managed to even find that device. Yes, both the iPad and the NAD are on the same network. It just doesn’t work. I really can’t be bothered to continue with such a shoddily coded app. Deleted.
nur mit Mikrofon
leider können die aufgenommen Kurven später ohne angeschlossenen Mikrofon nicht editiert werden.
Sehr schlecht
No Connect,eine Schande für Dirac
Full MacOS Dirac live for all receivers please
Less and less people own PC’s and Macs. Could we please have the full fat MacOS version of Dirac Live on iPad, so we can use a tablet instead of a Mac/PC. Ideally available for all receivers where the microphone is plugged into the receiver itself, such as Arcam receivers etc.
Why is this even here?
Downloaded the iOS app as instructed in the QuickStart guide that came with my NAD M33. After creating a new account I am immediately instructed that I must download and use the MacOS app. What a waste of time!
Logged out and back in to the iOS app and finally got to the measurement section. Despite the test signal being deafening and worrying it might blow my Martin Logans, the app complains the s/n is too low. There is no discernible background noise in the room. Useless. Will try the MacOS app and hope for a better experience.

Useless app
It does find my Onkyo RX50 but get no microphone signal so I can’t do any measurements. Tried a Umik-1 with same problem. It’s not the mic cause I am able to use voice memo app with no problem.
