[PD] A 6th order hilbert transformer?

[Alexandre Torres Porres]

Awesome, I can code it based on that :) but which order is it?

I see it has 4 biquads, but it doesnt look like an 8th order because some
coefficients are zeroed out, so I'm confused.

Another question, does it work at any sample rate? This question is also
aimed to pd's hilbert~ abstraction by the way.

cheers
