Hi,

I've been using the FFT analysis tool in Excel but find that it's
clunky because the FFT calculation is not "live".

Could someone either post the Excel code for an FFT and inverse FFT or
point me in the direction of where I can find the code?

I've spent a fair amount of time Google searching but can't find a
worksheet which calculates an FFT and inverse FFT from scratch, only
can find worksheet examples using the Analysis Toolpak FFT.

Thanks,

Art
