I like processing, but can't give you a correct answer to this.what
everybody
can tell you is that fft will become available woith flex and
actionscript3 , for the
moment that function is still buggy, but you can play with it (
amplitude works) ; http://labs.macromedia.com/
citate from http://labs.macromedia.com/wiki/index.php/Talk:ActionScript_3 ->
computeSpectrum and FFT
The computeSpectrum seems to work fine using readFloat to access the
byteArray. To do that I use the following code:
while(i>1024){
spectrum.position=i;
sprites_array[Math.round(i/4)].scaleY=(spectrum.readFloat()*100);
i=i+4;
}
Now if you actually want a spectrum graph instead of a raw wave you need
the FFTMode set to true. But that just seems to return a random mess and
nothing like a spectrum graph. Am I missing something or is the FFT not
working as it should?
------------------------------------------------------------------------
I've had the same results with FFT not working.
You can also use the following:
while(spectrum.bytesAvailable) {
spectrum.position=i;
sprites_array[Math.round(i/4)].scaleY=(spectrum.readFloat()*100);
-----------------------
i=i+4;
}

hi all,
looking for flash to java and vice versa communication examples (via
xmlsocket?). crossplatform. like a way to control a processing.org app
with flash and vice versa. i have in mind the mario klingemann did
something like that, but i can't find it on his site. anyone?
i like to use processings fft to use it within a flash app for example.
thanks: lars
