Hi friends

I m trying dirac , room acoustic correction , i easly made it to correct my windows system sound but no way to use it in sonar via its asio driver mode ...asio dirac drivers don t even show in sonar !!

Anybody succed to use this baby ?

I have... but I do it with dedicated hardware. I tried out the Dirac software and found that the room correction was pretty amazing, but the driver was crap and getting it to work with anything was a pain. So I went the hardware route. I have an Emotiva XMC-1 that is the DAC/preamp/correction/router for my system and I loves it. I am 100% sold on Dirac, it is far and away the best room correction I've ever used. I wanted the XMC-1 because I use home theater speakers, and because I wanted a surround solution (I have a 7.1 setup).
 
Other hardware options that are cheaper, but still pricey, can be had from MiniDSP. They have a line of 2-channel Dirac Live units that are $800 each (price includes calibration mic) that are quite nice. You have the option of analogue or digital on the input and output side. They also have a $1000 surround unit, but it is analogue I/O only. The digital one (DDRC-22D) could be placed right in line between a soundcard and DAC, or looped out an AES output and back in to the soundcard if you wanted to use the DACs you have and add Dirac.
 
If you want to go the software route, contact them and see if they can offer help. They aren't wonderful, but aren't useless. Also you can ask them about trying out their VST plugin. They have one, it is just in private beta at the moment. However they will usually let you try it, if you ask.

You right they proposed me the plugin and it s working exellent ....i thought about the dedicated hw but ...i skipped that ...software is more than enought ....i found that transiets are that here versus reference but the overall clarity is better ...smoother ...maybe too much ,, can t tell but high level stuff ....

Is it the demo that limit to 8 measurement or is it all like this ?

8 measurements is how they do. I guess they don't feel more are needed. Even if you buy a Datasat AP20 it still only does 8 near as I know. Given how good the results are, I guess they are on to something. I do my measurements trying to follow their positioning guide as close as possible and I like the results. The other important thing is, of course, using a good calibration mic and loading in the correction file for it.

I used the sonarworks mic ..my sound is not dead center with dirac but i done it like fool ....the key is that they also on the impulse area and measurement varies also verticaly witch makes a sweet spot exeptional
Reference V4 will come maybe and we will see

The Sonarworks mic will work fine, you just need to have a calibration file to feed to Dirac, one that is made for grazing incidence (meaning pointing at the ceiling) also called a 90 degree calibration. If you don't have that, might be worth buying a MiniDSP mic. They are both the same basic design of mic, and probably use the same capsule.
