The Hilbert transform accomplishes one type of complex signal decomposition that applies to phase shifts by complex number multiple: the complex signal c(t)=x(t) + i * Hx(t)
and then [hilbert~] is not a hilbert transform, it makes two different transforms on the same input signal such that one output is almost the Hilbert transform of the other output, but i think I recall that the low frequencies' shift differs significantly from 90⁰. Anyway, [hilbert~] is meant as a thing that can be used to make a Hilbert-like effect while taking just a small fraction of the computing power.
