The official NFFT library repository

Improved version of the NIST Statistical Test Suite (STS)

Audio visualization on the Unicorn Hat using FFTW

OpenBSD sndio Spectrogram

Fast transforms over finite fields

A very simple Cython project which demonstrates how to call FFTW natively

Code to compute ionization field from density fields and source catalogue (CIFOG)

MPI parallel version of the FTDock protein-protein docking algorithm

FFTW interface for Ruby/Numo

Simple and lightweight audio visualiser.

Built with C++ and FFTW3. The objective is to read data from an accelerometer and export its data in the frequency domain, using the fast Fourier transform.

Sound processing project for Epita S4

Code to compute the HI 21cm and 3HeII 3.5cm field from density fields and source catalogues

Descreen filter for PPM images.

Audio Spectrum Analyser

Simple program to display the spectrum of the sound stream that is playing through PulseAudio in the terminal with unicode characters.

DO NOT CHECK OUT THESE FILES FROM GITHUB UNLESS YOU KNOW WHAT YOU ARE DOING. (See below.)

pa-aspect is the PulseAudio implementation of the Aspect spectral visualizer.

Very small µmagnetic solver
