ios - Retrieving Data from AudioKit's FFT Plot -


i'm working on project involves recording audio microphone of iphone, feeds through fast fourier transform (fft).

i've found audiokit.io has demo in actively monitors microphone input , can display plot of fft.

i have equations , logarithms plan analyze audio data with, need retrieving fft data sent plot in audiokit. i'm having hard time finding functions/methods drive data fills plot.

can point out find fft data in audiokit?

the fft code audiokit uses pretty standard. take audiokit's plot , reappropriate code wish:

https://github.com/audiokit/audiokit/blob/develop/audiokit/utilities/plots/akaudiofftplot.h https://github.com/audiokit/audiokit/blob/develop/audiokit/utilities/plots/akaudiofftplot.m

there find heavy lifting being done starting @ line 118 updatefftwithbuffersize

the other stuff plotting may not need.
