C++ DSP Tools

• matplotlib-cpp

  10 4,173 0.0 C++

  Extremely simple yet powerful header-only C++ plotting library built on the popular matplotlib

I am aware of this excellent matplotlib C++ wrapper. Are there any C/C++ tools similar to scipy.signals? I currently use the python tools to generate header files and can translate algorithms to C++, but I would like a more direct well to develop in C++.

• Simple-FFT

  2 165 10.0 C++

  Header-only C++ library implementing fast Fourier transform of 1D, 2D and 3D data.

FFTW is a pretty popular and very fast FFT library, if you're after absolute speed. I generally just use Simple-FFT, you just need to wrap the container of your choice (your own, a std::vector or std::array or std::span) in a type that is subscriptable with parenthesis (operator()) and off you go.

• WorkOS

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• KFR

  5 21 5.7 C++

  A benchmark for comparison of FFT algorithms performance

  

KFRLib seems excellent for audio DSP: https://www.kfrlib.com/
