Trying to learn how to use this analyzer with my IPhone.
using pink noise from Tidal. not sure about the i-phone mic, or anything else either for that matter. Ron, if this is a distraction glad to delete it.
I think it might be better if we all put our curves on this thread, which I started precisely for this purpose:
Post Your Frequency Response Curve!
1) Download https://apps.apple.com/us/app/spectrum-analyzer-rta/id490078884 2) Set the adjustments to: Program: FFT Plot Weight: Flat FFT Size: 16384 Window: Blackman Average: Slow Graph: Simple Scale: Decade 3) Position the microphone side of your iPad at your ear position. 4)...

My strong suggestion, Mike, after futzing with my iPhone for a week is . . . don't use an iPhone! An external microphone (I think the most important element) on a stand and attached to an iPad makes this whole process much easier and more accurate and more repeatable. I downloaded Spectrum Analyzer RTA for $20. I'm using an Earthworks QTC40 microphone on a stand.
