FFt analisys at chosen frequencies… (gabor?)
Hello folks, :)
I’m using the gabor objects to analyze material for resynthesis, but the gbr.peaks external allows
just to choose as argument to get the lowest or the strongest partials… I’m wondering if there is a way
to get the amplitude of some particular frequencies instead… I’d try with a massive fffb but first I want
to be sure there’s no better way…
thank u very much…!
It depends what you want to do – also what kind of bandwidth you need. If you need to know that there is a sine component at a farily specific frequency then you may need to peak track using gabor / sigmund~ (the new improved fiddle~). If you just need to know how much energy is in a particular band then you could make a suitable patch for use with pfft~. However, you say you’re doing resynthesis – in which case you probably need to use gabor or similar.
So – perhaps you could give a bit more detail on what exactly you are trying to achieve?

You’re right… What I’m trying to achieve is a simple algorythm which analyses energy of tempered scale’s freqs and transposes that energy on simple sinus fixed on the same scale…
The final pach would be obviously integrating many other tasks (i’m still focusing the final result :)) but for the moment I just wanted to get this in the best way…
Thank u very much for your help… :)

Well, sigmund~ is perfect… :)
thanks again!
