[chuck-users] Using FFT 'manually'

[Siepie]

Hello all,

My name is Siebe, I'm a MT-student from the Netherlands. I've just started experimenting with ChucK on Windows XP a bit and I really liked how quickly I was able to get things working. For my study I might be interested using ChucK for music and audio analysis. I'm currently trying to figure out how to 'manually' work with an FFT-class, by using .transform(float[]) instead of .upchuck(). But as far as I can see, the transform function for the FFT does nothing, in contradiction with the .transform(complex[]) function for the IFFT class, which seems to work fine. Here are two examples to clear up my point:

The working IFFT code:

The not-working FFT code:

My question is, am I doing it right? Since both examples are pretty much the same, my guess is that both should work. Is this a bug in the i386 version? Or are users with another OS experience the same?

Any help would be much appreciated.
