Gunnar Bolle, FPrefect@t-online.de Simple FFT component Feel free to use this code Based upon a pascal routine from - Don Cross Thanks Don, nice Job. If you want to know more about FFT and its theorie visit http://www.intersrv.com/~dcross Thanks to Kees Huls for providing me the missing author information // Please note : I didn't have the time to write a sample application for this. Please do not ask me about how to use this one ... If you're aware of FFT you'll know how. Otherwise, try some of those neat Button components at DSP. They're quite easy to handle.TDSXFastFourier -
