PRICE: a high-quality image manipulation and enhancement application, also suitable as a multi-window image viewer. For GNUstep and Mac.

Gqrx is a software defined radio receiver powered by GNU Radio and the Qt GUI toolkit. It can process I/Q data from many types of input devices, including Funcube Dongle Pro/Pro+, rtl-sdr, HackRF, and Universal Software Radio Peripheral (USRP) devices.

Generic simple and efficient Fast Fourier Transforms (FFT) implementation using policy-based design and template metaprogramming in C++

math lib for .NET. n-dim arrays, complex numbers, linear algebra, FFT, sorting, cells- and logical arrays as well as 3D plotting classes help developing algorithms on every platform supporting .NET. Sources from SVN, binaries: http://ilnumerics.net

The CLUNK C++ library provides support for real-time 3D(binaural) sound generation. It puts virtually no limitations on the developer; people who have experienced working with other solutions (such as SDL_Mixer or Creative OpenAL) will respect this advan

... or a Proth test can be run; this is best implemented with FFT mod (3^3p+1) using GWNUM library. A sample implementation (a patch to the LLR program) is available from Batalov.

A Qt library for Fast Fourier Transform (FFT) of real samples. Based on the FFTReal library.

Tiny-DSP library contains c sources of a fast, tiny, portable and generic FFT (Fast Fourier transform) and inverse FFT. Supported are all power of two sizes (like 2,4,8,16,32,...) for one and two dimensional floating point arrays.

mpg321 is a completely Free drop-in replacement for mpg123. It has been designed to work as a drop-in replacement for mpg123, for the use of front ends, shell scripts, etc. It does all mp3 decoding using the high-quality integer-only MAD library.

Python FFTW as the name suggests are Python bindings to the FFTW3 C-library from http://www.fftw.org. They use numpy and python ctypes, and often offer about twice the performance compared to the fft routines included in numpy.

This program transforms the sound or the image using a single large FFT window and allows to do many interesting and strange effects to sounds and images. There is included another program who does extreme-time-stretch of the audio.

Foad is an open source software which receive an EKG Signal from scanner, WFDB database or heart sensors. Finding patient disease started by taking Fourier transform (FFT) from input signal and extract a single cycle. Based on some heuristic algorithm the most important feature like P , Q , R , S , T captured and feed to trained neural network. and so the final decision made by CNN library. As mentioned before this software also capable do some image processing on scanned paper to lower...

Tune is a note/chord detecting program for use with guitars, pianos, or voices. It uses an FFT to analyze incoming sound and computes the root frequency.

Numerical package Parallel EXECution. Using a numerical package like Octave, 'npexec' distribute computation of a math formula among various network elements, collecting result automatically. ->y=npexec('fft(x.^m)', 'm=-8:8','x=ARG');

FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain with a highly interactive GUI to manipulate and display the spectral data.

GENIAL is a C++ library for signal and image processing. It uses template-generic techniques, multi threading, cache optimization and SIMD instructions for Pentium (MMX, SSE, SSE2, SSE3) to achieve high performance: FFT,DCT,Convolution,Linear Algebra...

eXtace is a 3D audio visualization tool (or eye candy depending on how you look at it). eXtace requires ESD (Esound) for its sound input source. It performs a FFT (fast fourier transform) on audio and displays it via various graphical modes.

This project is to implement a kind of educational program which will demonstrate FFT algorithm and help students better understand Fourier transformation.

A C++ wrapper for the fftw.org C library. It provides a simple C++ application base which handles FFT data and application. Operations such as power spectrum derivation and so on.

For a given signal, pstool calculates a one-sided power spectrum, i.e. the portion of a signal's power falling within given frequency bins. This is done by employing a one-dimensional real-to-complex FFT routine on an MPI cluster.
