Best Audio Spectrum Analyzer App for iPad?

[Ron Resnick]

What is the best RTA/FFT application for an iPad? (It does not have to be one of the free ones.)

Thank you!

I bought the core tools some years ago- https://studiosixdigital.com/
I'd say that the biggest shortcoming might be the built in mic, which can be bypassed with a better mic offered by this outfit. Lots of additional tools available on a + basis.
Best? Dunno.

Thank you, Bill. Does that software require a specific mic prescribed by that company?

(I am envisioning being able to use my own mic to enable the software in the iPad to be more accurate versus the mic built into the iPhone.)

Has anybody had any experience with this one?

Dunno if it works with third party external mics. You could ask.

I downloaded the one in the link above. It seems pretty good.

Windows? Rectangular? Hamming? Blackman? Oh my!

Which is the best window to use for our frequency response analysis purposes?
