[PD] Multiplying signal by complex number to create and see phase shift

Greetings All

I plan on adding a phase shift to a signal/a wave file I import which is
easy enough mathematically
example: if the signal is x=sin(2*pi*1*t)
to do a phase shift I would just multiply x*e(-i*pi) which would phase shift
the signal by 90 degrees.

But how does one multiple signals by complex numbers in PD like -i?

note: there will be a several different phase shifts so a simple
hibert transform won't work in this instance
