Does anyone know of a really good, fast FFT implementation in AS3? I write a lot of audio signal processing code in AS3, and some of it uses FFTs (Fast Fourier Transforms) which can be pretty CPU intensive. I have my own AS3 FFT which is pretty good (about 15x faster than the one in as3mathlib), but is nonetheless ~7x slower than my own C++ FFT on which I based my AS3 version, and over 20x slower than highly optimized native FFT implementations (e.g. the one in Intel IPP).
I've looked into Alchemy, but unfortunately it doesn't appear to have any efficient means to pass Vectors of Numbers :-( I've come across a few blogs where people discuss the possibility of doing FFTs with PixelBender, but I haven't found any implementations yet. -Gerry Beauregard _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
