# Delaying the analysis will not work, because analysis data is an one block audio signal. If you delay it not a integer multiple of a block, the synchronisation of different delayed bin analysis, get lost.
# I made two different versions of spectral delay, one using delay before inverse FFT, other after it. Both doesn't work :-) but the second one gives good results for some certain delay times. I don't understand why this result happened.

# 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~]
