General purpose fft
WebDigital signal processing ( DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space ... WebGNU Radio flow graph describing a general purpose FFT Dicke-switched solution for usage with front-ends implementing sky, load or frequency switching. Basically it computes the Fast Fourier Transform (FFT) from the complex sample stream and saves it to file sinks. A in stream averaging procedure is implemented through a Single Pole IIR filter.

WebSources for KISS FFT can be found in the project's GitHub repo. To perform direct and inverse transformations for real-valued time data we need to compile kiss_fft.c, which implements general purpose FFT, and tools\kiss_fftr.c, which implements real-valued data stuff. What's left is to implement bindings. http://mc.stanford.edu/cgi-bin/images/7/75/SC08_FFT_on_GPUs.pdf
