Yeah, Actually alot of micrphones will have a frequency response graph avaialble for their mic's so this would be a good aaplication to have around. Does anybody know of a app similar to this for windows? I am surprised you guys don;t hava thread with different mic's and the Calibration graphs to go with them..

Well, there are several reasons why we don't.
We presently recommend the Behringer ECM8000 microphone with preamp or the Galaxy CM-140 SPL meter. We have calibration files available for them both on our
downloads page.
Equalization of subwoofers (which is what REW is used for mostly) require microphones (or very good quality SPL meters) to be able to accurately extend down to 5Hz.
Many microphones are specifically tailored for voice and don't extend that low (I suspect your Shure is that way). Even when they do extend to very low frequencies, (such as in the case of the ECM8000 microphone), they require calibration professionally to get the values needed for the very low frequencies. Generally what the manufacturer will supply wouldn't be of much use in that regard.
Below is the specification graph supplied by the manufacturer for the ECM8000. It extends to 60Hz.
Below that is the professionally calibrated results graph shown to 5Hz of the cal file we provide when fed into REW software.
Do you feel that any graph software could pull the calibration file from that specification graph? See the problem?
