FFT

Hello,

I have got a problem…
I want to read the values of an external adc and after that I want to execute an FFT-algorithm with the adc values.
The result should be the real and the imaginary part of the signal, so I can calculate the magnitude out of them…
Is there any existing arduino code framework for this problem?
