I have seen many examples of vDSP that realize the FFT / IFFT with real numbers but I have not seen any event that realizes the FFT / IFFT with complex numbers. Can you indicate the direction I should take? Thank's you in advance.

A complex number is just 2 real numbers that you (or the FFT code) decide to multiply using complex arithmetic. – hotpaw2 Apr 28 '17 at 17:13
