# You can take a look at this page for help in FFT.
# How did you impelement the buffered analysis?
# I think something like this could work: If the number of bins is
2*N, prepare N tables with size N samples. 1st table has one in 1st
sample and zero everywhere. Similarly n'th table has 1 in n'th sample
and zero in other samples. This tables will be used to pick up n'th bin
from the mixed analysis.
# Then prepare 2*N [*~] objects and multiply real and imag output
of [rfft~] with [tabreceive~ preparedTableN]. This way every bin will
be seperated, every pair has the amplitude and phase information of
only one bin.
# Then apply delay's to every pair and sum all delayed real and
imaginary parts seperately. Finally put these two signals to [rifft~]
# If I doesn't have two final exams this week, I'll try to implement what I've said. Good days!

hi list,
is there a possibility for binwise spectral delay with fft? i tried to write the analysis in buffers and read it time-variably out before re-synthesizing, but that didn't work (in fact buffer writing / reading the analysis did not work at all).
