At this moment only 1d operations are implemented, mainly because KFR is audio-centered library.

But 2d FFT can be performed with 1d FFT and reordering.

I would be interested in this too.

Upcoming KFR 5.x will include multidimensional array support and 2D FFT.

All KFR6 features are now in main branch
