An implementation of the fast Fourier transform (FFT) in C#

Where can I find a free, very quick, and reliable implementation of FFT in C#?

That can be used in a product? Or are there any restrictions?

Solution

  • AForge.net is a free (open-source) library with Fast Fourier Transform support. (See Sources/Imaging/ComplexImage.cs for usage, Sources/Math/FourierTransform.cs for implemenation)
