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! -ugur guney-

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). mirko
