Hi, Ludwig<br><br>I&#39;ve tried making some different Hilbert transform objects--although my attempts failed b/c I really didn&#39;t understand the calculations well enough.  I was trying to make some that used a 1024-point table based on Fourier behavior.<br>
<br>However, there&#39;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.<br>

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