I even mean a third algorithm... I am focused more the empirical mode decomposition put forward by Huang, ... after splitting the signal in IMFs they are individually analyzed by Hilbert transform, or other time frequency transform of choice... Im more looking to EMD, but I just found some matlab code which octave seems to be able to run, and theres some C functions... going to look how achievable it is, and going to ask permission from the author to make Pd externals based on them...
