but here's a discussion about the ECM8000 mic and cal file over at DIY Audio
|
I looked at the posts and graphs you're referring to at DIY audio. I think you need to be cautious when testing microphones, since small mic element positional differences can account for some large changes in response that aren't due to the actual microphones response differences.
In addition, where you're not testing in a controlled environment, rapid changes in system response can occur, and even the smallest positional difference in a mic element can exaggerate the outcome. Where I see a comparison that shows the tests done at many centimeters apart between the elements, I don't assign it much validity I'm afraid..... (just my opinion, please, no cards and letters).
As I said in your other post on this subject,
If you're concerned about accuracy beyond home use, then you should get your microphone calibrated. We make no claims about the accuracy of the cal file we provide for download other than it is correct for the mic for which it was carried out.
As a free service we provide this file for anyone to use with their ECM8000 knowing that it may not be absolutely accurate with their ECM8000. For home use, a movement of the mic element a few feet can easily result in several dB of level change, so it would be fine to use in a home theater...
