Ok I am at a loss here. I have my Xmc1 with my Dirac full license but every time I try to move the curtains in, when I release the mouse it either makes the graph so huge I can't even find the target dot anymore, or it doesn't move the curtains at all. I have tried to do this on two different computers. One with Windows 8 and one with Windows 10 and I have the same problem with both. I thought it might be the touch pad on my laptop but I actually bought a USB mouse and had the same problem. So what am I doing wrong?

If you have any anchor points near the curtains you must remove them first. |

Ok I guess that makes sense. Would I need to move the orange circle below my target end or beginning frequency? And also has any of you tried only EQ in up to 500 or so hz? And if so did you like the results?

Just think of it as if the orange balls "block" the curtains... so you must move them out of the way before moving the curtains. One other thing worth noting: the curtains define the ends of the frequency range over which processing will be applied. The presumption is that "inside the curtains" the Target Curve is the one you set, and "outside the curtains" the Target Curve is the measured response that was there before. (You can't have "no Target Curve"; so, outside the range you specify, it remains what it was before.) Because of this you CANNOT have a sharp "jump" at the edge of the curtains.... the ends of the Target Curve inside the curtains have to "match up and connect to" the unchanged curve outside the curtains... and the software will sometimes prevent you from making changes that would result in a sharp discontinuity. For example, it Dirac Live measured your sub as being -10 dB at 19 Hz, and you were to set the left hand curtain at 20 Hz, and tried to set the Target Curve right at the 20 Hz end of the range to 0 dB, you wouldn't be able to. Since the response of -10 dB at 19 Hz is outside the curtains, the software would consider that point to be "fixed", and would force the line inside the curtains to bend down at the end so it could meet the line outside the curtain without a sharp step in the line. (-10 dB at 19 Hz, and 0 dB at 20 Hz, would require a sharp step; the software would probably adjust that to something like -10 dB at 19 Hz, -5 dB at 22 Hz, and 0 dB at 25 Hz.....) In order to allow the two lines - inside and outside the curtains - to connect smoothly, the software would "bend the two ends so they line up where they meet". Ok I guess that makes sense. Would I need to move the orange circle below my target end or beginning frequency? And also has any of you tried only EQ in up to 500 or so hz? And if so did you like the results? |

Thanks Keith that is a very good explanation of what the curtains are and how to adjust the curve at the end. Should help a lot of confused people who are new to Dirac.

Keith,
I only use Dirac from 20 Hz to 350 Hz for my main left and right speakers. Hopefully the screen shot below illustrates what you’re describing. Note the “bent” after spectrum green lines at both 20 Hz and 350 Hz.
In my case the maximum dB difference appears to be about 6 dB at 350 Hz and 5 dB at 20 Hz. Do you have any recommendations for those that just use Dirac for the bass region? Would smother transitions be helpful?

Heck I have had the Xmc1 with full Dirac for two years. I tried a bunch of times to move the curtains and just gave up. Then I got the new computer and thought it would work. Nope same thing. Just dealt with a full house curve. It does sound really good this way. But curiosity got the best of me.
Has anyone else run the curtains in and liked the results?
Thanks again

Thanks again I did some comparisons of corrected and uncorrected measurements. Dirac doesn't make very drastic changes to about 5khz and up unless you make like 10db cuts in the target curve. There "may" have been more going on in the corrected measurement but as far as actual frequency response it only varied by a db or so throughout from the uncorrected response. |

One more question. How does one make a nice curve when only eqing from say 20-500 hz without pulling that section up? My speakers in my room have a nice natural curve but to bring the corrected area into a nice like house curve I would need to bring those frequencies up a bit. And I know that is a no no

And I know that is a no no Just experiment with the curves until you get something you like. The Dirac/XMC combo will not overdrive things into clipping. If you saved your measurements you can simply re-load them and play with the curve and create new filters. No need to run the measurements every time. |

I will give it a go Don't forget to save your projects with descriptive names so you can go back to any of them easily. Just load the project and create the filters. Once you get a good house curve you can save just the curves for each channel or group. Then if you rearrange things or get new speakers you can use the same curves that you know work for you. |

While experimenting, I save my curves in named folders too but then I also place a txt file (create in Notepad) that lists some of the details. It's hard to keep track of everything so the notes really help. |

Like withnewsubbackagainstwall so by putting notes with it that would be really nice. And clean up the look. Lol |

Well thanks for all the help on this folks. I just redid it and listened to your advice. It worked. So far I am kind of liking my new settings. I still have to listen a bit more. I may tweek it a bit. But so far so good. I am worried about pulling up my 20-700 hz range. So right now I am eqed up to about 800 hz as to not have a huge peak right after my eq cutoff frequency. If I trusted raising my levels down their I could get an outstanding house curve. My speakers do really have a very nice gradual rolloff from 1000- to 20,000hz. What do you guys think?
Well after listening for a while just a bit to much up top for me. I went back to a more gradual house curve. I do like the highs untouched but I have this spike that I can't get rid of without raising my lower frequencies way up more than I would like.
I could play with speaker placement again . But the placement now was done with rew. And this was the best overall position. Which gave me less peaks. So what to do?

Dirac should be able to tame spikes pretty easily without creating a boost elsewhere. Also you could try a target curve with an overall 5dB or more cut as explained in the article linked here: www.minidsp.com/support/community-powered-tutorials/263-custom-dirac-live-target-curves |

But what I am saying is if I don't EQ say up to 1500hz I end up with a spike right after 700hz. Which I really was trying to only EQ to about 500. Which gives me to much of an energetic sound. I loose the body of an acoustic guitar so to speak. But I do love the uneqd. highs. So I am trying to figure out how to get the best of both worlds. But without raising the target curve at the low end. I think the only way is to redo rew and find a different location for my speakers. |
