I am solving problem related with FFT. I am having situation like, I have to forward incoming data stream towards FFT Library function or FFT routine that can transform the time domain data to frequency domain data.

Which Library in C# do I need to use ? Do Microsoft provided this ? or I need to use some third party libraries for this?

Answer 1

You can have a look at this library:

I use this library a fair bit, though I've never used its FFT functions:

There is also this library which seems to get alot of mention, but I've never used it so I can't comment on it's quality.
