I do agree that some want the ability to adjust and tweak and hopefully the Full version will supply that. Some just want to be able to tweak even though Dirac LE sounds good to them, others are having issues and want to use the software to get to the sound they want if possible.
Nothing wrong with that.
I'm going to mention here though, that my system's sound has been improved using the current Dirac LE. Much better than the previous Pioneer MCACC system and much better than without Dirac on the XMC-1.
May not be a popular opinion, but it's the truth.
I will most likely look at the Full version when it comes out and will also wait for reviews.

It does work with my equipment and Thiel speakers, but like I said, I will look at the Full version in case I can make it even better. |

Here you go Tony, sorry I didn't get these up yesterday. And thanks for teaching me how to do this   Is this the result of a shot mic or are you experimenting with your speakers' innards?  Reminds me of Mickey Rourke's over-modded face! |

Does this mean we should send our mics to Cross Spectrum for calibration?

I'm very disappointed with Dirac. It was suppose to be the miracle cure. It does make my music tighter and cleaner; but at the cost of an overly bright treble and loss of bass. I like organ music and the Mixtures unnaturally scream, but the pedal bass notes have disappeared. I've gotten it useable by cranking up my subwoofers after Dirac, but it seems like replacing one compromise with another.
I hope this is just an anomaly: an error in microphone calibrations, or software bug. Otherwise, I'll be removing it. Yet another UMC/XMC embarrassment.
Sincerely
/b

I am working on something that I plan to post up soon. But I need screen shots of as many peoples measurements as I can get. Please post all channels of the before graphs of Dirac. Attachments are fine. If you saved your measurement, you can open dirac and load your measurement and click load. load your file and then select filter design. Checkmark the avg before. then take a screenshot. (there is a awesome screenshot tool built into windows called snipping tool). Thanks in advance. Tony Tony, My charts with your file, please analyze and reply if time permits. thanks Paul       |

I'm hardly surprised that it's been common to find excess bass in many applications, some of the guys have 3, 4 or even 5 sub woofers. Many of them mixed brands, power and sizes. Frankly I'd be amazed if we didn't see it. You don't go to the trouble and cost of multiple subs unless you have a fondness for bass. Hence, when the excess is tamed by DIRAC, there are complaints that there isn't enough bass, hardly surprising or unforeseeable. Personally I read absolutely nothing into the results regarding the commonality of DIRAC bass correction being downwards, it's exactly what I would expect.
Cheers

What are the odds of all these various owners of various speakers in various rooms, mine included, that show all of them with dips at 7000 hz and up?
The lower frequncy are harder to get a handle on because of room gain, but high frequency should have less interaction with the room and they probably, shouldent all report so low.

My Dirac measurements on page one were done with Tony's custom file and it still showed a droop up high. |

The lower frequncy are harder to get a handle on because of room gain, but high frequency should have less interaction with the room and they probably, shouldent all report so low. A benign rolloff beyond 7 kHz is normal in a typical speaker/room. For example, the first set of posted measurements on this thread. An earlier and deeper drop similar to the second set of measurements is not. Withought having full confidence in our measuring tools, however, there is little inference of value that could be skimmed from any set of measurements. In any case, what I learned from my years of experience with Tact room correction is to generally tailor the target curve so it follows the measured rolloff beyond 7 kHz or so. And if you wanna get adventurous, you tilt the entire target curve ever so slightly to boost or cut the tweeter output. A 5-10 dB boost in the range of 7-15 kHz by the lone stock Dirac curve as shown in several cases is just too agressive. |

Actually, the curve Dirac chose for us is not bad at all. It is fairly straight from 20 Hz to 20 KHz with an overall ~5 dB drop. A few years ago Harman International conducted and published a study about a controlled experiment involving target curve preferences. They concluded that a straight target curve (similar to Dirac's) was best pleasing for the chosen critical listeners, albeit with an overall drop of 10 dB. Until Full Dirac is available, I would suggest that XMC-1 users raise the sub level (after programming the filters) by 3-6 dB. That should bring the bass back in full force. I wouldn't go any higher though. I agree with your sentiment in regards to the Dirac target curve but don't confuse target curve with microphone calibration. The calibration file for the mic is to ensure the measurement is correct. if the measurement is not correct it does not matter what the target is because the correction will not be correct. I would also say that it would not be appropriate to use a calibration file that is not specifically created for you mic. There can be large enough variation between mics that they require a specific calibration for each mic. This is why mini dsp has a serial number specific file available for it's mics and why Cross Spectrum calibration is so popular. As far as I can tell the calibration provided for the EMM is the same file for everyone, unless they have somehow tied the specific mic to the Dirac user key, not likely. But this means that to some degree or another not all the mics will provide the correct response to Dirac. Here is an example between my Umik and the 90 Degree cal file from Mini DSP vs the EMM and the cal file provided in the Dirac download. This is Front left 80z crossover to subs. Tis tells me one of the cal files is not correct and I tend to believe the Mini DSP file more than the Emo one. Could I get a copy of that mic cal file and how do I go about using it in Emotiva Dirac SE? |

I have a couple questions the first being settings for the Cmedia mono capture device as it appears in windows. I noticed in it's properties it has an AGC option. I turned that off because I think it would screw up measurements. Also it defaults to 44.1 16bit audio. I changed that as well kto 48kHz 16 bit. That setting only matters if the Emotiva Dirac SE app uses the device in shared mode not exclusive mode.
Does the Dirac SE app operate in shared or exclusive mode? I guess I can test that by trying to use another application with the mic at the same time as Dirac.
If it does operate in shared mode would it not be best to set it to 48 kHz?
What sample rate is the test tones and processing? I'd think it's 48 kHz no?
