Now I do it like this, 4 moving average FIRs,
5, 10, 20 and 40 taps
and a linear blend between them based on log2 of the bin number
I filter forwards and backwards, backwards after the shift of the bins
for formant shifting
the shift is done reading with a linear interpolation from the forward
here I am using 5 point average on the lower bands and 20 point on the
higher bands
doesn't sound too bad now, but I am still looking for a better solution

it seems that my artefacts have mostly to do with the spectral envelope.
What would be an efficient way to extract a spectral envelope when
you ha e stream of bins, that is one bin per sample, repeating
0,1,2,... 1023,0,1,2...
and the same stream backwards
1023,1022,...0,1023,1022...
?
