socketmanI am remiss in forgetting to thank you for your contributions in the analysis Tony started. The data you provided via your CS calibration (which you paid for) really helps confirm what Tony suspected and many users reported based on their calibrated ears. You both have contributed in a positive way to improvements in the XMC-1 and have been class acts. Thank you so much... Mark Thank you for the Thank you my pleasure  Tony got me hooked and enquiring minds want to know , the rest is history. Richard |

Lonnie and KeithLI am curious what you think about the recent data Tony and socketman present. Can you elaborate on this? From what I can see, it looks like Tony's suspicions based on his non-anechoic chamber data largely agrees in trend with data from CS, and this largely agrees with the ears of those saying that DIRAC through the XMC sounded off to them in specific ways that - curiously - aligns with the data. So truth is, either CS is off in their calibration or the file from Emo/DIRAC is. One of them cannot be right. So, which is it? Can you elaborate on what plans there are to investigate further? Given it does not appear that the data presented would require any major rework on the XMC, I presume you are open to an adjustment to improve the product? Correct? Thanks! Mark

Ansat, So you saying the EmotivaMicCalOA file with the OA for off-axis with this description "# Emotiva Mic off-axis calibration file" is the wrong file? That they gave us the on-axis calibration file instead? With all due respect, I do find this a little hard to believe but it doesn't mean you are not right since you have some information to back it up. I don't have any evidence except to believe that Emotiva could have made this error. But I could be wrong. The Emotiva file (90deg ?) and the Cross Spectrum (0deg) file have been compared and they are virtually identical whereas the Cross spectrum 90deg file does not compare in any way or fashion. Reread what Tony posted last nite and try to absorb everything and you will see that he has backed up this claim fully. I would also say please feel free to continue using the Emotiva calibration if it works for you. Richard You guys have done great work...and I prefer to read your version  . Oh! Looks like he put the files out there...I'll check it out and run Dirac for grins. And for the record it still sounds great but not quite right...which I why I'm still seeking new development. Perhaps Emotiva will follow up but since this is the forums, there is no timeframe around that nor do I expect one. |

I don't have any evidence except to believe that Emotiva could have made this error. But I could be wrong. , I don't think that emotiva gave us an on-axis calibrated file. I believe that the reference microphone used to calibrate the EMM was using an on-axis file. in the end, this could be something as simple as 1 sentence in a 42 page manual. For example, the XTZ info that I posted yesterday states in a single location in a 42 page manual that the XTZ must be pointed towards the speaker for full range measurements (measurements past 5khz). In fact, I was specifically looking for the direction of the microphone and had to read the manual twice before I found it. Tony |

The other key and it's more important to me....
How does it sound with the CS 90 degree off-axis file? I'll run it in a bit but that's the question that I'm looking for...
I understand the need to provide graphs for scientific purposes but in the end, I only care about how things sound. Given your efforts, the least I can do is check it out.
My system was already really good w/ Dirac (like I said), so we shall see.

The cross spectrum folder is empty. Opps ! had it set to hidden instead of read only. corrected it and re-synced the file. Tony I still don't see it. I downloaded Socketman's file he provided earlier so...ok the filters are downloading to the xmc-1 now... |

If you don't , dirac will overwrite the file with the default. Order of operations close dirac, replace file, set to read only, open dirac. Tony |

Before or after it takes the measurement? I'm guessing after.... I did verify that it was overwritten - darn it! |

Very odd, mine was not marked read only yet it was not overwritten.

Lsc, did you set the file to read only? If you don't , dirac will overwrite the file with the default. Order of operations close dirac, replace file, set to read only, open dirac. Tony No I didn't. When does it overwrite it? Before or after it takes the measurement? I'm guessing after.... I did verify that it was overwritten - darn it! Dirac overwrites the file when it opens and then immeadiatly loads it. Once it's loaded, nothing can be done to change it or use a different calibration on an existing measurement. Tony |

Honest, I put the file in then opened dirac. Cant try it again right now the kid has it on at the moment.

I marked it read only and took the measurements. The highs didnt dip like before and it just looks more accurate overall. Once the painfully long process of uploading filters to Xmc-1 completes, I can check it out. The last dirac run was very good but it ran the emm-1 calibration file. Hopefully it'll sound better than the last R else I'll have to reload the last run. |

I think this goes with out saying but I will say it any way, different does not always mean better. Our sonic memories are not very good so I would suggest you use material you are familiar with and give the brain a chance to adapt before any judgment. I would be handy to see your graphs at some point.

Tony, you mentioned that you would post a step by step procedure to replace the file, is this something you are still going to do. It would help some of us who are unsure of the entire process.
I have found the file it shows a sentence then a lot of numbers, the frequency and then plus or minus for add or cuts to the levels, do you just delete all the numbers in the file with your numbers or do you also replace the opening sentence found in the file. I am sure I am not the only one following this thread who is afraid to screw something up. (Maybe I am the only one).
In case we do screw something up do we need to save the original file so we can fix the file if we mess up, a lot of unkowns here.
Thanks for all your help.

Download the zip file in my signature. There are instructions in there. You do not need to back up the original. Dirac generates a new file every time it's opened. (This is why when you replace the file, it needs to be set to read only) Tony, you mentioned that you would post a step by step procedure to replace the file, is this something you are still going to do.

Are you able to use both files with Dirac using a Emotiva mic? Which one is consider best?
