As I understand it the change to a sweep was an internal software convenience for Dirac and nothing more. From a users prospective the version 2 sweeps take a little less time.

Both the DL2 and DL3 products use v2 software identical to the PC and Theta products. And before someone asks, we are currently waiting on first article DL2 hardware from the build house. Made in the USA! We hope to be shipping early next year.

I have been waiting a long time for this.

FWIW, Datasat is finishing up testing on Dirac Version 2 and will be moving to V2 shortly.

How will this V2 compare to Trinnov?

From a users prospective Dirac Live v2 is very, very similar to V1. The changes under the hood are mostly about making it easier for OEMs to add the IP to their products. The features list of Dirac Live v1 and v2 is identical. I question if a trained listener could hear the difference between them in a double blind test.

This is Dirac Live v2 http://www.dirac.se/en/consumer-products/dirac-rcs.aspx

I woder why Datasat didn't went with Trinnov instead of Dirac Live. Nothing against Dirac Live, but the results with Trinnot are mre perfected...if that's the correct word to use.

Has the move to v2 been confirmed then?

Will this change affect any of the following:

1. Ability to process at 192khz without down sampling?
2. Dirac to measure and set speaker distances?
3. Dirac to measure and set levels?

At the time the decision was made (6 plus years ago) the Trinnov IP was unfinished and had no real presence in the marketplace. In fact it was unclear at the time whether or not a real Trinnov product was ever gonna make it to market. But of course all of that has changed! I am glad to see that Trinnov has pulled it together and have such an interesting product.

Dirac Research has an IP called 'Dimensions' that has qualities similar to those promoted by Trinnov that are not included in Dirac Live.

Interesting. Do you see any chance for the "Dimensions" to be a part of Datasat in a near future?

"Has the move to v2 been confirmed then? ..."

I am not an authorized spokesperson for Datasat but I understand the tech and IP so ...

Will this change affect any of the following:

1. Ability to process at 192khz without down sampling?

ANSWER: No. The internals run at 96kHz. This is the case with all audio processors. A dirty little secret is that some run at 48kHz! (And they never tell you ...)

2. Dirac to measure and set speaker distances?
ANSWER: Yes

3. Dirac to measure and set levels?
ANSWER: Yes but ... you still want to touch it up using a sound level meter just to be sure! rolleyes.gif

The software on the Dirac Live website is the software that will be used to generate the filters.
I invite you to download and play with the demo.

Hoping someone can point me in the right direction. I tried to run Dirac now that I have the Seaton Catalysts and i get the error indicating it could not find the sample recording for channel 1 when it is taking the measurements and will not continue. I stupidly forgot to take a screen capture of the error so please forgive me if I have it wrong..The end result is it wont let me take the measurements...............

The issue is that it takes the samples on step 1. if I pass pay in all 8 channels it registers in the green zone not a problem. It's only in step 2 that when you start taking position measurements that it fails....

I plan on grabbing another laptop and doing the full installation again. I think my Java might be corrupt. ....

Please note: as much as we like and respect Carl Huff, he is not an authorized spokesperson for Theta Digital. His comments regarding Theta's use of Dirac Live and similarities or differences between our approach and any other are purely speculative.

Most of the time people with knowledge are more helpful than the "official" spokemen. Besides no interests are crossed. I pesonally enjoyed reading all Carl's comments and find them quite unbiased.

True - it's always refreshing to get insights from someone close to the development process smile.gif, and who is looking for user (or potential user) feedback. I appreciate everything that he and Curt Hoyt do. Without Curt, I don't know if I'd be trying to use the R-972 to compare vs. Audyssey imminently, and without Carl's involvement, Dirac would be a pipedream for everyone outside of the HTPC world.

As a non-$20K user and a bit of an electronic EQ comparison guy, I'm VERY, VERY interested in the DL2 and if the bass management control of shelf filter octave rolloff (i.e. options other than the 12 db/octave rolloff for high and low shelf filters) is more creative than what's in a Denon 4311, possibly the DL3. So the more that Carl keeps us in the loop, the better. wink.gif

I was and for Datasat as well. Altho I was integral to the effort that brought Dirac Live to the consumer product space the actual IP was developed by Nilo Casimiro Ericsson, Mathias Johansson and their crew at Dirac Research in Uppsala Sweden over an intensive 12 year period of research and development.

If the challenges you had getting the DL2/3 to a prototype are anything like the still unsolved issue of getting HDMI audio into a HTPC from a multichannel external source, running Dirac, and then turning audio out to an amp in anything like a stable and cost-efficient manner, I can see why it's taken you a few years to move from a conceptual idea to an actual product.

Being that this thread is also a help thread, I will give a try at solving your problem.

In my case, I had the same issue as you. I found that I needed the volume at the mic to be above at least 85dB's. Anything less and the measurements would not proceed even though I was getting the green in the channel test screen. Try upping the volume of the speakers by increasing the volume on the RS20i. Keep upping the volume until the measurement proceeds to the next channel.
