Dirac Live Exclamation Mark issue

Yes, I agree. I gave my friend an analogy that went something like this: DSP is a process, just like frying onions is a process. Tools have to be used and procedures followed in the right order. Onions have to be peeled and diced before they are fried. You can try frying the whole onion and dicing it later, but the result will not be the same.

- Acourate: here is your knife, here is your pan. It will happily let you fry the whole onion and dice it later if that's what you want to do. What's bad (or maybe good): you have to learn the entire process and dice the onion yourself. The outcome depends on your skill in dicing onions and frying. What's good: you can use these tools for anything you like. Can make deep fried onion rings or any onion dish that requires a knife and frying pan.
- Audiolense: give me your onion and I will dice and fry it for you. Tell me how you want the onion diced, and how long you want it fried for. What's good: you don't have to learn the process. Much easier for beginners. The outcome is the same. What's bad: knives can be used for other things besides dicing onions. Less versatility and flexibility. Can't make deep fried onion rings if the option isn't included.
- Dirac: give me your onion, and I will dice and fry it for you. Give me a general idea of what you want (caramelized? translucent?). What's good: very easy to use. What's bad: less control over the outcome. Definitely no deep fried onion rings for you.

There are others.

- MATLAB/Octave: here is some metal. Forge your own knife and pan. Then go dice it yourself and fry it. Literally true, you have to make your own tools by typing in equations.

I like the culinary analogy, tenuous as it may be. The problem with onions is, most people don’t caramelise them properly. They throw them in with all the other ingredients, stewing them when in fact, onions always go first. They go first by themselves, until they are properly caramelised (i.e. sweet and delicious).

The deep-fried onion rings don’t fit this paradigm, because here the onions are no longer a base staple of a dish but a snack on their own.
 
As far as your question is concerned, are you talking in general (when all works OK in Dirac) or specifically for this "imprecise measurements" situation?
In 3.4.4 version there is no imprecise measurements. Above it you can't trust the corrected optimize response even if you have all good meausrements at least with Arcam and other parent related brands. I would like to know if Denon/Marantz owner with, let's say 3.97 or 3.10.1 version, ever check the results with REW. Fro instance set xo at 80 Hz for all groups of speakers, calculate the filter and load it in Denon. Check with REW if waht you saw is what you got.Then change the xo of only one group of speakers let's say the surrrounds xo to 100Hz leave the others at 80Hz, calcluate see the preview and check the preview of the other groups. Does it changed or not? If it doesn't change,load the filter THEN check with REW if the preview is what you really got. It is better to do this with only one measurement at MLP . If you took 13 measuremetns I chieck with RTA in REW to compare the preview and the real thing.
With Arcam nothing can be trusted above 3.4.4.

Everything is fine with you too? You were very active on this topic, hence the question.

My problems seem to be solved with 3.10.1, at least it sounds good for the first time, but I didn't measure with REW.

If you check post #133 and the following ones you will see that on my main system the issue still persists but there is a workaround by creating n number of measurements and then checking with REW which are the ones that are OK-ish

The good news is that on my new home office system it seems to be working fine!
I have no idea why though.....
Anyway that is some progress! FYI @Flak
 
Hi, so what problem does the upgrade actually solve?
Is it only the measurement error issue or more fundamental than that ref stereo image etc?
 
Just tried the V3.10.1 beta as others have, wowser - Dirac software was indeed broken.
What a amazing difference, stereo image is back, the frequency curtains actually work and my 2 channel sound hasn't been killed stone dead.
Thanks all.

Which exactly was the broken version again? I’m on version 3.8.2 and haven’t noticed the issues above.

It started with some people moving from 3.4.4, and when they encountered issues with the upgrade; they could not go back to 3.4.4. 3.4.4 worked fine previously. It appears that 3.10.1 has resolved the issues with many people. @ppataki has this flushed out your issues also?
 
Before 3.10.1 I had to use 3.4.4 to avoid the “imprecise measurement” error. When I tried 3.10.1 for the first time I did not get the imprecise error anymore, and IMO my system sounded the best it ever had. Unfortunately I had to go and tinker with it . I felt there was a bit too much sub bass and my imaging was moving around a bit. Anyway to try out a few things I adding a HPF to my mains (2.1 system with no XO’s set initially). After adding the XO the “imprecise measurement” error returned. Now I’m just waiting on Dirac for any suggestions.
 
What AVR are you running and how old is it? BTW this is a bad sign.
Its a new MiniDSP HTx with full range Dirac Live license.
Interesting you say its a bad sign, would you mind elaborating a little?
I have found with REW I get timing issues when sweeping through a crossover as well. I had assumed that it was the nature of digital XO’s, but….
