Hi everybody
(
I have just suscribed to this mailing list. I have used Pure Data for about 4
months (and GEM sometimes), for various applications, under Linux and Windows.
)
I have a question about spectral synthesis.
I saw a patch (in Miller Puckette's book, " Theory and Techniques of Electronic
Music ") that performs spectral synthesis like this :
there is a bank of sine oscillators, and the amplitude of each sine is
controlled by a graphic array.
I tried to do this a bit differently before, using rifft~ and a graphic array.
The idea was to resynthesize a sound from spectral data directly drawn in the
array, unfortunately it didn't work. Maybe rifft~ works with rfft~ only ? I
started from a classic analysis / resynthesis patch and used the resynthesis
only.
Has anyone managed to do (re)synthesis (without any actual analysis : the
result of the analysis is drawn directly in an array) with rifft~ ?
Thank you very much
Julien
