Do you know a good and efficient FFT? [closed]

http://stackoverflow.com/questions/1592345/do-you-know-a-good-and-efficient-fft

this question The performance of the FFTW sets the standard for arbitrary length FFT's especially for non power of 2 lengths in 2 and greater dimensions. The commercial license for FFTW is 5000 which may or may not fit in your budget. However it.. problem in which case you have a few more options and if you can further either pad or sample your data to power of 2 lengths then many libraries will offer reasonable performance. Check out this list of FFT algorithms that FFTW used for comparison..
