Hi, Ludwig
I've tried making some different Hilbert transform objects--although my attempts failed b/c I really didn't understand the calculations well enough. I was trying to make some that used a 1024-point table based on Fourier behavior.
However, there's an interesting and useful approximation given by the hilbert~.pd patch (provided in the extra directory perhaps?). It uses two all-pass biquad filters that are ~90 degrees out of phase with each other to approximate the hilbert transform.

I was wondering if somebody made HHT objects in Pd like: [EMD x], splitting a signal in IMF (intrinsic mode) functions...?
How hard would it be to implement?
