AlgART Java libraries for processing arrays and matrices are open-source product, distributed under MIT license. So, anyone can use them for free without any restrictions. Main features: 63-bit addressing of array elements (64-bit long int indexes), memory model concept (allowing storing data in different schemes from RAM to mapped disk files), wide usage of lazy evaluations, built-in multithreading optimization for multi-core processors, wide set of image processing algorithms over...

A cross platform dual channel FFT based Acoustic Analysis Tool to help engineers analyze live professional sound systems using the transfer function. One feature is the ability to capture four sample plots, average them, and invert to aid in final EQ

Fast fourier transform algorithm written on IEC-61131-3 Structured text programming language for programmable logic controllers. Algorithm is split-radix FFT. StFFT is iterative contrary to more common recursive approach. Iterative solution was chosen because PLCs don't have support for recursion. For compatibility with as many as possible PLC models, algorithm have dependency only on sine and cosine functions. Dual licenced under LGPL and Commercial licence. For commercial licencing contact tamitech@tamitech.fi Author Jaakko Pasanen

A simple, straightforward complex FFT Implementation in C/C++. It is designed to give good performance for non-power of length 2 FFTs. Only 1D , unit-stride implementation for singe core processors available as of now. USAGE HSFFT is designed specifically to handle time series data efficiently. The software is structured very similarly to available open source softwares like FFTW and kissfft.

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

DTMF - FFT Декодер-кодер DTMF сигналов в реальном времени. Возможности: • спектроанализатор (БПФ) • кодирование 2-х частотных сигналов DTMF • декодирование 2-х частотных сигналов DTMF

...The program will read in a calibrated .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. The software implements Fast, Slow, Impulse and LEQ; A, C and Flat Weighting; Ln and Noise Dose analysis; Octave and 1/3 Octave band analysis; high resolution FFT analysis and spectrograms. Band analysis can be made using fast FFT methods or slower, but ANSI standard methods. Source code requires MATLAB + Signal Processing Toolbox. Developed under MATLAB R2010a (but might work with some earlier versions) Executable version does not require MATLAB and runs under Windows XP, Vista, and Windows 7.

The FFT library to "Keep It Simple, Stupid" This is the original home of kissfft. Most recent development is at https://github.com/mborgerding/kissfft Please ask questions on stackoverflow.com

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.

FastFrequency API written entirely in Java ME, is able to provide to obtain the frequency of a sound signal using the FFT algorithm implemented by the radix-2 after the windowing signal via Hamming windows.

An implementation of the sparse FFT algorithms discovered by Mark Iwen and described in http://www.math.duke.edu/~markiwen/DukePage/Papers/JcFFTsubmit.pdf. Used for benchmarking in http://www.ima.umn.edu/preprints/jul2010/2326.pdf.

JTransforms is the first, open source, multithreaded FFT library written in pure Java. Benchmark results show better performance than FFTW. The latest version is available at http://github.com/wendykierp/JTransforms.

A PC-based fingerprint recognition project which is mainly featured with a fast FFT algorithm for convolution in ridge enhancement. It is a remarkable for study or any commercial purposes.

A low memory scaling distributed 3D FFT library. The library is designed for calculating complex‐to‐complex Fast Fourier Transforms (FFT’s) on 3‐D distributed data. It is based on FORTRAN90 and MPI with the underlying FFT calculated using FFTW3.

Program that does an FFT (Fast Fourier Transformation) algorithm on a 1 dimensional time buffer read from a file. It will display graphically.

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 the final costs.

funkGen is a software function generator intended as an educational tool. It has a number of basic generators and transforms, but can also combine those into more complex waveforms, Ouput sound files, graphics, or just raw data.
