diraclive-latest.exe is correct. It's under the very first heading at the top of the page "Dirac Live" which underneath states: Supported Brands: ARCAM, AudioControl, BRYSTON, DATASAT, EMOTIVA, FOCAL, Integra, JBL, Lexicon, Lucie, miniDSP, MONOPRICE, NAD, ONKYO, Pioneer, quadral+, ROTEL, StormAudio, THETA DIGITAL, WISDOM Thank you for the reply and is the other software a suite of programs similar to REW for those without the processors mentioned above? just curious as to what it is but i dont want to d/l and install just to appease my curiousity.  These are some of the best but the equipment associated to use the below software is much more expensive than Dirac's supported list. Arc Genesis, Lyngdorf [Room Perfect] and Trinnov |

There is a software-only version of Dirac Live. (Basically, with that version, the "engine" that runs the Dirac filters resides on the computer rather than in a processor.)
Note that, since Dirac Live is running on the computer, it can ONLY normally be used with audio coming FROM the computer. (It acts as a software module that intercepts and processes audio that is being played by the computer.)
So it will work with a "home theater PC", or for audio that you play on a computer, but isn't intended for other hardware sources.
Since it is a software module that intercepts the audio stream inside the computer it MAY not work with all player programs or streaming services (some may not allow you to intercept their audio stream).
It may be possible, with the correct hardware and software configuration on the computer, to route audio from other sources through the computer, and apply the Dirac Live correction filters to it. However I don't have any details about either of those possibilities... so you would need to ask Dirac about them directly.
Also note that, when the filter engine resides in a processor, after using the Dirac Live software to take measurements and create the filters, you can then disconnect the computer.
But, with a software-only version, the computer must be running whenever you wish to play something through the Dirac software.

2 questions for the guru's in this forum. Running an XMC-2 + MiniDSP-HD and 2 subs, should i use only 1 sub pre-out and split inside the miniDSP-HD or run 2 sub outs from the XMC-2 to the 2 inputs on the MiniDSP? Second question, Should i only use the MiniDSP to time align the 2 subs and let Dirac do the rest, or use REW to do some basic PEQ and then use Dirac for the finishing touches?

I would be inclined to expect better results using a single subwoofer output on the XMC-2 going to the Mini-DSP. The XMC-2 already supports a single channel of bass management (the subwoofer outputs are monaural - even if you use multiple outputs). If you use multiple subwoofer outputs on the XMC-2, connected to multiple subs, then Dirac Live will be applying individual corrections to each sub output - based on the speaker itself and its location in the room. The Mini-DSP will then in effect be summing those back together and then applying its own corrections to the result.
The bottom line is that you will be applying corrections to multiple outputs, which are intended to be sent to different speakers, at different locations, and which may include phase and timing corrections. Then, at the MiniDSP, you may be mixing those outputs back together, before splitting them again, and then applying more corrections. To be quite honest it may work great... but, if you are summing those inputs to the MiniDSP, then you absolutely are introducing more OPPORTUNITIES for things to go wrong in interesting ways.
(If you're keeping the left and right outputs separate at the MiniDSP then you are simply "double processing the signal", which also introduces more opportunities for weird problems.. but probably somewhat less so.)
In other words, it only makes sense to do room correction in one place, and bass management in one place. Therefore it is more likely that Dirac Live on the XMC-2 will do a better job if it believes it is "sending output to a single sub"... and the MiniDSP is doing the job of "combining your subs into a single very good sub".
Note that this is merely my opinion, I haven't tried this, and there are a lot of ways in which your results may vary....
It is also going to be very different depending on whether you do actual "room correction" in the MiniDSP or JUST use the MiniDSP to time align multiple subwoofers to act as a single sub.
(The latter is far less likely to produce odd results.)

I’m not a guru, but I am using miniDSP HD as Keith described. The other thing that I did was to gain match the subs using the volume controls built into each sub. This could be done in the miniDSP, but I used the volume control on each sub to match the volume level so that no clipping occurs, getting the best combined frequency response, and the overall sub volume was about 10 dB higher than other speakers before running Dirac. I have a sub on order that has some built in tuning, and I plan to optimize with the built in tuning before moving up the chain, if that makes sense. I have been meaning to try MSO (Multi Sub Optimizer) that automatically optimizes EQ filter to import into miniDSP www.andyc.diy-audio-engineering.org/mso/html/www.avsforum.com/threads/optimizing-subwoofers-and-integration-with-mains-multi-sub-optimizer.2103074/ |

DiracLive v3.1.2 now available. Do we need to uninstall prior DiracLive versions first? |

I always let it install into the default folder. |

The video mentions disabling unused inputs (2 mins 32 seconds in) before running correction. I cant seem to find where to do this.
Anyone know? |

"Channels", not "Inputs".
Setup the processor for the active Channels you will be using, IOW, active speaker channels.

Anyone know? Not inputs but channels. For each preset set any channels/speakers to None if you have no speakers connected to that channel. So for example if you have no rear speakers, set them to None in Setup > Speakers > Preset > Size > Rears. |

I updated Dirac to 3.1.2 today and ran it 3 times.
The first time it loaded the filter and allowed graceful exit from the app and left the volume at .5dB full steps, 40.5dB.
The second time, Dirac closed unexpectedly upon loading the filter, the volume was left with showing .5dB full steps, 40.5dB.
The third time, the filter was loaded into the processor, Dirac exited gracefully, and the volume is showing .0dB full steps, 40.0dB.
So I'm just looking out for how many times the app will close unexpectedly, similar to what was happening with Dirac 3.0.11.
The half step volume thing seems to be pretty random on when it "doesn't" happen. I just use the Geebo fix and run the volume down to -96dB to clear it, because cold boots don't fix it anymore.

Friends, its been some time since I’ve found time or thought I needed to run DiracLive again. I’ve downloaded 3.2.1 or whatever the newest is, did that today. RMC-1 also has the latest? So, what happened to the green levels and what am I supposed to do now that they’re gone. Please forgive me for not keeping up but “LIFE”. I humbly request help.  |

So, what happened to the green levels and what am I supposed to do now that they’re gone. Please forgive me for not keeping up but “LIFE”. I humbly request help. With the last few updates the Volume Calibration has gotten away from the "green" zone stuff. I guess it has to do with so many variables in systems, plus it depends on which mic is used, etc. You just need to test for your system, basically. When I have tested the EMM-1 mic, it seems to be more picky about how the Volume Calibration is setup vs when Dirac gets to Measurements. Start low, do just one mic position to test the outcome, then after success you can adjust as you would like and use more mic positions like you should. With the UMIK-1, it's much easier because the sensitivity is set higher by default (but this is adjustable should one want to measure higher outputs). With that said, this 3.1.2 version is different, but more of the same. There's still a big difference between how loud the pink noise plays in Volume Calibration and the sweeps play in Measurement, but it's not really different like it was a year ago. To get Measurement to play sweeps at about 85dB, I set the mic to 100%, and set the speaker channels to play at -22dB, but I increase the subwoofer channels in Vol Cal to -15dB so they play at the same level as the speakers in Measurement (within a dB). This makes everything play loud enough to get good results but not so loud that it hurts anything. Bottom line is that I suggest keeping the mic at 100%. Then adjust as you like and as the results direct. The Dirac runs I've done today are mainly just to see what happens. I adjusted the Speaker/Subwoofer Channels higher each time I ran Dirac. edit: With a UMIK-1 mic, expect Measurement to play sweeps about 18dB higher than when setting up each channel in Volume Calibration. The exception will be with the subwoofer channels, which for some reason play lower by about 6dB so this is why I set them up in Vol Cal to be 6dB higher, or like I did today 7dB higher so they play just a little louder than the speaker channels in Measurement. I'm finding that making the subs play louder gets better results. But, you MUST try for yourself by starting out with lower volume settings and testing to see what works for your system. |

Hmm, all of my sliders are at 100%, Do I need to move my master slider down? How long does the FW install take? I think its stuck as its been doing nothing for well over 5 minutes (states that its starting that is) |
