Hi Pau, 

and thanks for the quick answer! :)

Yep, especially for the SpectralAnalysis/Synthesis part... There is actually 
nothing. But I don't understand, because SMS consumes too much CPU power and 
just having the spectrum should be quite enough for the most purposes.

That's unfortunate, because using buffers seems to be more flexible to me.

How ever, might it be sufficient to just spend my classes a private port for 
each,  for pushing audiodata into SpectralAnal and getting the spectrum out 
of it and vice versa for SpectralSynth?

Because I don't want to use CLAM::Ports all over the field... 

Thanks and Greetings,
