Using Fftw Dev C++
I second the fftw suggestion. One of the nice features of fftw is 'wisdom'. That is, if you call many times the same Fourier Transform (with the same array size), you can ask fftw to look for the fastest way to do it, and then it will use that way for all the following computation in your code.

DTFT and Convolution using FFTW library and C++ programming
Fftw Float
This project shows how we can perform the discrete time fourier transformand convolution using FFTW library and C++ programming language. Bysampling the signal given we have converted the input signal in the timedomain to the discrete.We have performed the discrete time fourier transform by using the inbuild libraray functions. The outputs obtained by theconvolution using FFTW are compared with the outputs obtained from thepure C++ programming to check the validity and accuracy. The compareddata is stored to text files and graphs are plotted to compare.
