is it possible to shift the phase of a whole signal of 90°?

i've tried allpass with filtergraph~ and biquad~, but I don't understand if the shift is applied over the whole signal or just in a part of the spectrum.

och.. I think I have to use an fft... any idea?

would it not work to use fft~ or pfft~(fftin~), into cartopol~, then take the phase in radians out of the right-outlet of cartopol~ and add constant of 0.5π?

OR take a look at hilbert~, its outputs are already 90° out of phase(thanks to raja! for leading me to hilbert~).

with biquad you can do something like that for sure, a simple hilbert transform is basically

[filtergraph~] has a phase display mode, that can be very helpful to understand things.

a highpassfilter.

doh... hilbert~ was exactly the THING!
thanks much both of you.
