I think the Dayton iMM-6 paired with Audio Tools RTA analyzer will help me get my system processor tuned in enough for the average / mid level audiophile like myself.

Nothing like any major delta 100-400Hz. In prior comparison M30 was v close match to B&K quarter- and half-inchers.
Not seeing how cal file is clearly off either, so I am missing something wrt ripple >4k.
Finally, 90deg cal might be nice (for grazing work?) but do not see why needed, really, for HT EQ regardless.

All calibrated with a B&K 4230 calibrator at 93.8 dB.

My Octave band SPL results using Audio Tools were within 2-3 dB of all except for the Umk-1, which read considerably higher at ambient room tone measurements. I had hoped that the Umk-1 and my ipad would have been my inexpensive portable iOS rig. I regrettably am not comfortable with the Umk-1 doing any serious measurements.
I have a feeling that the Audio Tools iTest mic may be the best solution for class 2 portable acoustic testing on iOS devices at this time.
I’ll post again when I buy and test it.

Thank you for taking the time to do this test and the write up! I’ve been looking for a portable measuring solution and it seems I may have found it. I typically use REW/TrueRTA on my laptop with a usb phantom power interface (MicMate) and my Behringer ECM8000 mic. I was thinking it would be nice to be able to have one solid, calibrated mic to use with that setup, but also to be used for a portable device- namely my ipad mini. The UMIK-1 looks like an excellent solution, especially since it can be used without any ancillary interfaces (outside of the lightning to usb adapter) which makes for a very lightweight, portable and fairly accurate measuring system when combined with AudioTools. When I contacted Herb of CSL, he had mentioned that the Dayton UMM6 and UMIK-1 didn’t work with iOS devices, but it seems that they do, in fact work with them. (MiniDSP also shows the compatibility and setup in a page here: http://www.minidsp.com/applications/acoustic-measurements/using-the-umik-1-with-audiotools-on-ipad )
Thanks again.
