The second post on that page says a lot. I've read these posts before when searching for Toole related info. Thanks. Yes! Specifically .... "The Harman curve is not a "target" in the sense that any flawed loudspeaker can be equalized to match it and superb sound will be the reward. The most common flaws in loudspeakers are resonances (which frequently are not visible in room curves) and irregular directivity (which cannot be corrected by equalization). The only solution to both problems is better loudspeakers, the evidence of which is in comprehensive anechoic data. Remember, the Harman curve relates to conventional forward-firing loudspeaker designs. Legitimate reasons for differences are different loudspeaker directivities - omni, dipoles, etc. - or rooms that are elaborately acoustically treated, or both." |

The microphones are from Emotivia and are batch calibrated. Pretty sure they buy them by the batch and do not produce them themselves. Check out Cross Spectrum Labs-https://www.cross-spectrum.com/ They sell individually calibrated mics and can also do calibration on mics you own. I don't know if they calibrate the Emo mic, but it would be worth it to check out. I got a UMIK-1 from them for Dirac on my XMC-1 and would never use anything else. The mic that came with my RMC-1L is still in the box and will remain there. The EMM-1 from Emotiva are NOT batch calibrated. Instead they are batch conformity tested and this is common practice in goods manufacture. This has been cleared up a few times from Keith or Lonnie All of the Emotiva EMM-1 have the same identical and single calibration file.
There are no calibration files for different batches. If batch conformity testing is done properly, each batch of EMM-1 should have a sample of a calculated number of mics tested to ensure that they are performing within the designed specification. If every one of the samples passes, then it is assumed that all mics in the batch pass, and meet the expected specification. If one fails, then the batch should either be rejected completely, or, each mic in the batch could be individually tested to confirm conformity or not, and individual mics rejected or passed. Actually that sounds worse. My point -and my apologies to Keith and Lonnie for not getting it exactly correct- is that the mic included with your processor is NOT individually calibrated. You may be lucky and win the Emo lotto and get a mic that closely matches the 'same identical and single calibration file'. If you want a mic that has actually been individually calibrated then you will need to get it from an outside vendor. If you want to use a mic to run REW you will want an individually calibrated mic. If you want to get the best results from Dirac you will want to get an individually calibrated mic. At the reasonable price for an individually calibrated mic from CS Labs (or other vendors) it was worth it to me just for peace of mind. A chain is only as strong as its weakest link, and the questionable matching of the mic in your Emo box to the single calibration file invites weakness into the equation. In my personal experience with the included Emo EMM-1 vs the UMIK-1 from CS Labs for running Dirac it took it from 'ewww, that's worse than using nothing' to 'wow, Dirac really sounds great.' YMMV |

For those who like to worry about things like this... we spec our individual microphones to be withing +/- 2 dB of the standard (and the calibration file).
Incidentally, if you purchase an individually calibrated microphone, it comes with its own individually measured calibration file. (It may come with several... and the one you want for use with Dirac Live is "the 90 degree calibration file".)
And there should also be a specification that says how accurate the calibration itself is. (The equipment they use to measure it must itself be calibrated... and the process of calibrating microphones is a bit tricky.)
Here are a few other things worth mentioning:
Technically speaking calibrated microphones are intended to be used anechoically. This means that it is assumed that sound will ONLY be reaching the microphone from one direction. (Sometimes you get two files... a 90 degree file and a zero degree file... but you almost never get a full "3D profile" except on really expensive microphones.)
Obviously, in a real room, some sound is reaching the microphone from many directions... and Dirac Live actually USES that extra information... However, since the DIRECTIONAL characteristics of calibrated microphones are NOT always specified... You can expect slightly different results with even different accurately calibrated microphones.
And, likewise, different programs, like REW, use different methods to include or exclude information from other directions.
And, finally, especially at higher frequencies, wavelengths are very short. This means that moving the microphone an inch or two, or moving the speaker an inch or two, can produce drastically different results. At 20 Hz a wavelength is around 50 feet.... to peaks and nulls in a standing wave are about 25 feet apart. At 10 kHz a wavelength is about 1 INCH.... so the distance between a peak and neighboring null is about 1/2 inch. (So, at 10 kHz, moving the microphone or the speaker a mere 1/2 inch could make a huge difference... or maybe not... )
(And, if moving the microphone an inch or two makes a difference, then so will moving your head an inch or two...)
What I'm getting at here is that you should avoid obsessing about trying to get a result that is flat to within a fraction of a dB at one particular spot. And getting a result that is flat to within a fraction of a dB over multiple spots is just plain impossible.
After a while the situation becomes comparable to using a precision LASER level in order to cut your lawn perfectly flat....

Note also that Dirac Live DOES NOT simply average those readings together.
While it "considers" all the readings they may not all receive equal weight... (So, for example, multiple readings that are similar may receive more weight, while outliers may be discarded.)
That's interesting about the V shape. So having intermediate mic points in the "mouth" of the V caused some issues? Also, must be nice to have such a quiet room! Right now, with fridge and HVAC off, the noise floor is 45dB(C) according to REW's SPL app. About 43dbC at the MLP at the moment but sometimes the refrigerator makes a couple db more noise. I always see it in the Waterfall at 40Hz. With HVAC and refrigerator off I pick up another 3-4db but I don't find it makes any difference to the measurements. Moving the computers and NAS boxes away from the MLP I was able to pick up about 6db. The reason for the tight arrangement and the V is to keep the mic inside the envelope of the shape of the angle of the fronts, not outside. The actual direct sound of the fronts that I listen to is bounced off the side walls, but if I get the mic too far left and right of MLP it also hears some of the direct (not bounced) sound from the side of the speakers facing the walls. This causes Dirac to get extraneous sound 1-2ms out of sync that does not contribute well to the listening at the MLP. When I had the speakers in a conventional front-facing and toed in arrangement, I used a wider rectangular pattern across both cushions on the couch, with good results. |

This is an important point that Dirac makes over and over and many people ignore. It's why you need to take several measurements, because Dirac needs to see what is common to most measurements and what is very uncommon ... and this is further assessed by frequency with mid-high frequency outliers being ignored. As Toole says: "No small detail adjustments should be made because it is highly likely that they are acoustical interference (non-minimum-phase) phenomena that two ears and a brain interpret as innocent spaciousness - room sound. "Correcting" these is likely to degrade the audible performance of truly good loudspeakers" |

If you want a mic that has actually been individually calibrated then you will need to get it from an outside vendor. If you want to use a mic to run REW you will want an individually calibrated mic. If you want to get the best results from Dirac you will want to get an individually calibrated mic. Actually, that is not correct. You just need a mic that is good enough. Good enough by itself. Good enough with software fiddling to compensate for the mic not actually being perfectly good enough by itself (i.e. adding in a compensating calibration file) Good enough (with or without a compensatory calibration file) that it's performance on any given day at any given room temperature in any given non-absolute silence environment is within acceptable limits. What good enough is can be open to subjective debate. For me, considering I listen to movies and music with the -25dB "volume" setting on my XMC-2, I am content with the minor decibel differences that the measured mics have been suggested to have from individually calibrated mics. (I will throw in calibrated to what? What is the reference mic that they use to compare the test mics with and who calibrated that and with what?) Perfect is not perfect at any step of the chain. Each step is simply good enough. The MOST IMPORTANT feature however is that after calibrating the room to your own personal Nth degree of accuracy, you absolutely must not change it. You may not enter the room to listen to music because your presence disturbs the reflections and invalidates the measurements you calibrated to. If you were in the room when you calibrated, you MUST wear the same exact clothes and be in the same exact position as when you measured. You may not move your window blinds/drapes/curtains of sofa cushions. Ever. You may only listen to the same audio that was used to calibrate Dirac. Anything other than the Dirac frequency sweeps will cause multiple frequency interactions that Dirac didn't measure. Minor mic variations are probably one of the smallest pieces of the pie. Play a constant tone wave through your system and use your individually calibrated mic to measure the dB. The reading will wander about within the space of a second by far more than any of the numbers in your calibration file. Easier. Take repeated Dirac/REW sweeps WITHOUT moving the mic. You do not get zero difference between any two measurements taken back to back. The differences are more than the numbers in your calibration file. |

You do not get zero difference between any two measurements taken back to back. The differences are more than the numbers in your calibration file. yep. yep. yep. And I will add that the "difference" that I've measured between my EMM-1 and either of my UMIK-1 mics (one from CSL, one from miniDSP) is about the same or less than the "spec" of all speakers I've owned, +-3dB. Any which way of testing I could think of to compare 3 mics vs each other and not compared to a 4th mic is what I tried, and using each mic to measure the results of the other two is really wacky. Convoluted? Of course it is! Needed? Absolutely not! Fun thinking of ways to test stuff? Absotootly! One mic vs another is simply a tone control, or a Harman Curve applier/negater. With the EMM-1 and Dirac default settings results in more bass, like someone turned up the bass control. I found myself adjusting the curve down to compensate. It's only a couple dB, but it was too much. So, after I bought the Umik-1's and got less bass, I use one of them instead. BTW the greatest differences are below 100Hz and above 10,000Hz. Between those two frequencies the variations wander a little, by an amount that is about the same as if you run 10 sweeps without touching the mic and getting differences in the resulting traces. One or two dB here and there. Just look at the cal files of any mic and you will find that the numbers go way up and down at the extremes. |

With all that being said I am super happy with the results I am now getting. It very well may be the mic I got with my XMC-2 is defective or damaged somehow. I did get two things with UMIK-1; a darn good sounding system in my living room and peace of mind. Both are easily worth the 100$ it was for the mic. I've spent more than that on a bottle of scotch and was happy too, but for a shorter amount of time.  |

Can someone help me out? I've been looking and looking for the source of the "Harman Curves". I'm looking for a source that originates from Harman, presumably from Olive, Toole or another of their colleagues. I'm looking for a reference to where the curves came from, and how the folks at Harman believe the curves apply. Specifically how Harman recommends they be applied to equalization of speakers in listening rooms. I find a lot of info for headphones. DEVELOPMENT OF HARMAN HEADPHONE TARGET CURVEA link from Dirac Live 2 page Target Curves for Dirac Live 2/3And a link from that linked page above used as a reference AES.ORGedit: Here's an important note about using the target curves for all speakers in Dirac: " Note: Use the very same target curve for all your speakers including the subwoofer. Do NOT use different target curves amongst speakers in the crossover region to the subwoofer(s) or you'll end up with a combined response that no longer follows the intended curve. Adjust high frequency fall-off according to your speaker's in-room response." edit2: marcl this might be it. A Study of Listener Bass and Loudness Preferences over Loudspeakers and HeadphonesAbout the same target curves.. What I have been telling all a long. Some seem to want to use different curves anyway.. |

I solved my Dirac sound quality issues by getting the UMIK-1. In my opinion Emotiva should offer that mic as an upcharge or just add 50-75$ and only send out that mic. Every issue I had is gone after getting an accurate mic. The default Dirac curve even sounds good. I switched back and forth between the Dirac curve and the Harmon +4 curve and there was very little difference. So little in fact I will keep both in the presets depending on what I'm listening too or my mood. The only thing I could tell was the Harmon curve was slightly more vocal forward. looking at the curves side by side and all else being equal that's about what I would expect too. Maybe a tad brighter on the high end with the Harmon but that would depend on the tweeter in your speakers as well. Prior to that the Dirac curve sounded like garbage and looking at the curve there is no reason it should. That's my two cents and 45 years of audio knowledge for what its worth. I would like to think years of building my own speakers, working in a speaker shop, and writing reviews for a well known but unmentionable audio web site should count for something  lol. Of couse should Emotiva want to start a new department dedicated to calibrating and testing their mics, they know where to reach me. This PACS stuff I do now would start to seem pretty boring then. Good to hear your issue is resolved. And, it could be you actually just had a bad mic from Emotiva. Most don't find night and day differences with Dirac as a function of the mic. I previously had the XMC-1 and compared Dirac with the Emotiva Mic to that with a Cross Spectrum UMIK-1. I didn't have any noticable difference other than I just felt more confident in the UMIK-1 because I had an individual calibration file. Mark But there are many here that have had issues with the Emotiva mic. Most (all?) issues have been solved by changing to a UMIK mic. I haven’t tried it even. Had the UMIK-1 before I got the Dirac kit. |

I've not tried the mic than came w/the XMC-2, though, and I've not followed closely enough to know how many have actually had issues with them. But, there's always a chance to get a bad mic out in the public. If I suspected a bad mic and didn't have a UMIK or didn't want to buy one, my first plan would be to call Emotiva and ask them to ship a replacement mic. Mark |

Had the UMIK-1 before I got the Dirac kit. Do you think it is possible the Emotiva mic works the way it does due to the belief/thought that room eq and such is not really something they believe in, or lightly believe in for frequencies up to say... A few hundred Hertz? Super general statement or question I'm proposing, but if one didn't put much faith into room eq, or didn't believe in its value past a certain frequency, one might choose to provide a mic that wasn't as accurate or stable past those frequencies. This, of course, is in addition to the mics that are flat out broken. Those things happen from time to time, but are more common when my first statement is true. This is not a dig on the company. They could have simply not provided a mic at all, which.. in my opinion, probably would have been more ideal than providing one. Those dollars could have been used as profits or invested into additional, value-add features like DLBC or a streaming interface, etc. I would think most people that are overly critical about Dirac being the best it can be are going to ditch the mic regardless. I personally never took mine out of the box. |

I did not feel the need to buy a UMIK. I used the XMC-2 mic when I got my XMC-2 and it worked fine. I did buy a UMIK out of curiosity. I like the standard USB connection on the UMIK. I’ve run both with Dirac and saved both on the XMC-2. In terms of sound quality, they are close with the UMIK getting the edge. Both “presentations” sound fine and unless I pointed out which was which, you would not know. I use the UMIK now because of the standard cable. I agree with Mark that the first step would be to call Emotiva and ask for a replacement if you are having issues and don’t want to buy another mic. If you want to buy a UMIK, by all means do. |

Something to consider with Emotiva Mic, there are 2 pieces to their setup, 1- Mic and 2- the cable. Their cable is active and provides amplification and digital conversion for the usb connection.
For me the cable was the problem.

I intended on buying a UMIK-1 from the very start. At just over $100 for either the miniDSP individually calibrated or the CSL individually calibrated, it should be an easy decision to just get one if only for peace of mind. The cost is less than buying speaker wire for adding 4 ATMOS speakers. miniDSP and CSL UMIK's are indistinguishable from each other, I've got both.

After 150 pages of Dirac back and forth, I find myself with a very basic question about getting things set up.
My XMC-2 arrived without a Network Interface kit. In fact, it was accompanied by a welcome letter that said Dirac was still being worked on.
After contacting Emo, I was told that the letter was an error and that the software is available as is the interface kit and one was being sent out to me.
The kit arrived with instructions to refer to my "Welcome" letter to set things up. My welcome letter said that the software was not yet ready and contained no instructions for proceeding.
Went back to Emo and got an email with a series of links. Sent in MAC address and have been waiting.
Downloaded Dirac Live SW and config file for microphone.
Emo confirms my Dirac MAC has been sent to Dirac.
Somewhere, I read that I will hear nothing from Dirac. That, if I run the SW with the network kit installed and my device (assuming XMC-2 as opposed to Network Interface Kit) is discovered, that means that Dirac has recognized the authorization sent to them by Emo.
Since it has been several days and I have not had the Dirac SW find my device (tried IP address for the XMC-2 to no avail), I am left thinking that one of two things is going on. Either Dirac has not acted on the registration sent by Emo or there is a configuration issue with the Interface kit. If the issue is the former, waiting is in order. If it's the latter, I might not know if a Interface configuration issue is keeping the Dirac SW from recognizing the device even if, perhaps, Dirac has recognized my MAC registration.
I sent Emo the MAC address last Monday. Any thoughts would be appreciated.

I guess all it took was to post the question. I had been rescanning for devices every 15 minutes or so and the last scan hooked up. I haven't read everything you posted in this, but...a key for me (thanks to ttocs here) is: 1) Connect the switch to the internet and power up the switch. 2) Connect the computer that has DIRAC on it to the switch and power it up (if it's not already). 3) Connect the G3P to the switch and power up the G3P. 4) Confirm the G3P has an IP address via checking in the setup. 5) Connect the EDNIB and power it up. 6) Once the switch shows (via its lights) that the ports the G3P, the computer w/DIRAC on it, and the EDNIB are connected to the switch and active...then go into the G3P setup and activate DIRAC in the setup in preset 1. 7) Load DIRAC on the computer that has DIRAC on it...at that point, the G3P will show up. If I do #5 before #3...mine never works. Same for others...even though Emotiva says "it shouldn't matter" Clearly, for some...it does. Mark |

Went back to Emo and got an email with a series of links. Sent in MAC address and have been waiting. Downloaded Dirac Live SW and config file for microphone. Emo confirms my Dirac MAC has been sent to Dirac. Somewhere, I read that I will hear nothing from Dirac. That, if I run the SW with the network kit installed and my device (assuming XMC-2 as opposed to Network Interface Kit) is discovered, that means that Dirac has recognized the authorization sent to them by Emo. Since it has been several days and I have not had the Dirac SW find my device (tried IP address for the XMC-2 to no avail), I am left thinking that one of two things is going on. Either Dirac has not acted on the registration sent by Emo or there is a configuration issue with the Interface kit. If the issue is the former, waiting is in order. If it's the latter, I might not know if a Interface configuration issue is keeping the Dirac SW from recognizing the device even if, perhaps, Dirac has recognized my MAC registration. I sent Emo the MAC address last Monday. Any thoughts would be appreciated. It can take more than week before your MAC address is officially added by Dirac for use. It has been 4 days and it is the weekend. Try periodically, When it works you will see XMC-2 as a device to select. |

lol. Of couse should Emotiva want to start a new department dedicated to calibrating and testing their mics, they know where to reach me. This PACS stuff I do now would start to seem pretty boring then.
