• Top/Science/Technology/Electronics/Signal Processing
• Top/Science/Math/Analysis/Transform Calculus

• - Source Code in Fortran for FFT from "Programs for Digital Signal Processing", 1979, IEEE Press, ISBN 0-87942-127-4. The book is necessary to use and understand these source code listings.
  
• - A real-time spectral analysis application with spectral analysis tools, statistical functions and visualization system. It can analyse data from WAV files or sound input from microphone or CD player. Shareware.
  
• - Links to many sources of FFT code and information.
  
• - Arbitrary length FFT C-source, 3D gravity simulator, quantization of FIR filter coefficients. C source.
  
• - Power-of-two real and complex FFT software that is faster, and more accurate, than conventional iterative implementation of one-dimensional FFTs. Based on a propietary algorithm.
  
• - Fast free C FFT library; includes multi-dimensional, real-complex, and parallel transforms.
  
• - Source code and links for many different FFT implementations and related information.
  
• - A package of Fortran subprograms for the fast Fourier transform of periodic and other symmetric sequences.
  
• - Contains Fast Fourier Transform source code (C, C++, Pascal), tutorial, and math theory.
  
• - Links and various Fortran FFT implementations.
  
• - Benchmark comparing speeds of many FFT codes. Results from many machines, and code to run it yourself.
