Discrete Fourier Transform Tool (DFTT) for real-valued data like audio files and CSVs.

W-SLDA Toolkit: Self-consistent solver of mathematical problems which have structure formally equivalent to Bogoliubov-de Gennes equations.

A small and fast Discrete Fourier Transform library

implementation of DFT and FFT in small scale

Single file forward and inverse Sliding DFT in C, C++ and Python

Implementation of the Dirichlet Kernel Deconvolution algorithm for precise FFT parameter estimation and near-perfect elimination of spectral leakage. Additionally includes the "Cleaned" STFT and the Frequency Modulation Transform. Repository for code contained in Matthew McQuistion's Applied Mathematics Honors Thesis at Brown University

A classical Density Functional Theory code to calculate the properties of hard spheres or Lennard-Jones particles in planar geometry i.e. near an infinite hard or soft wall.

A C-based academic project demonstrating signal processing using Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT). Includes custom implementations for both complex and sine/cosine forms of DFT, and an optimized recursive FFT — ideal for learning frequency-domain analysis from scratch.

Computing & Benchmarking DFT & FFT in C

Simple FFT in C for low-power embedded systems

Fast Fourier Transform library for Lua

Small library for in-place bit reversed DIT DFT radix-2 FFT using the same definition as MATLAB. Functions are provided for 1D and 2D FFTs as well as fftshift and fftshift2 which rearranges the components to place the 0 frequency term in the centre.
