But FFT is a transformation which obeys FFT(x+y) = FFT(x)+FFT(y)
and also linear FFT(c*x)=c*FFT(x). Where x,y element of C^n, c = const.
This would mean that all you'd get is a expensive way of mixing. Not
morphing. To morph two spectra one would have to interpolate along the
frequency axis. I.e. move a high frequency peak to a low frequency peak. To
do this one would have to recognize the peaks and define a way in which
they should move.
Similar to graphic morphing, where you usually set points that will be
transformed into each other.
