A list of paid, free or open source C++ (C plus plus) Digital Signal Processing libraries, plugins and tools including Fast Fourier Transform (FFT) and 1D and 2D wavelet transforms and more. Sourced under a creative commons. This list will be updated regularly. Email over the URL, if you wish to be included.

C++ DFT libraries

• DSPFilters – A collection of useful C++ classes for digital signal processing. [MIT]
• FFTW – A C library for computing the DFT in one or more dimensions. [GPL]
• iir1 – IIR Realtime C++ filter library. [MIT]
• kissfft – A Fast Fourier Transform (FFT) library that tries to Keep it Simple, Stupid. [BSD-3-Clause]
• pocketfft – FFT implementation based on FFTPack, but with several improvements. [BSD-3-Clause]
• wavelib – C implementation of 1D and 2D wavelet transforms. [BSD-3-Clause]
