Parece que hay gente en la lista de SC que está trabajando el tema de Wavelets ver correo abajo. Avisame si quieres que te envie la conversacion completa son como 36 correos:

Mencionan un plug-in para wavelet en SC llamado WaveletDaub.sc en sc3-plugins/NCAnalysisUgens

I agree, I looked at the server code extensively and (to lesser degree at the) Bison grammar and I see no limitation to SC to develop wavelets.

Actually for super large auditory landscapes e.g. thousands of wavelets, SC is most scalable as I discovered experimenting earlier.  

However my goal is not just to use them for the sake of modernity, I was thinking to use as auditory objects as opposed to signals. Signals in SC are quite limiting the range of the applications, but if it is broken into short-lived wavelets it is much more suitable to build new apps. 

I suspect that you can load a set of wavelets that comprises an auditory scene, and zoom in and out naturally without much difficulty. Then this gives a new tool for composers:

http://www.wolfram.com/mathematica/new-in-8/wavelet-analysis/visualize-scalograms-in-three-dimensions.html  

You cannot manipulate the traditional def of signals, and it is much harder to build some  sort of landscape with them.

I am sure there have much smarter folk who figured things on earlier, so I am on the hunt.

Hola,

Será que alguno de ustedes a ensayado este tipo de síntesis
concatenativa [1]. Habrá implementación en Pd  o SC?.

Por lo que entiendo esta basada en Wavelets como Gabor en lugar de la
FFT.
