The library is so small that you can directly include the sources in your project or you can pre-package it as a static library and then link it into your project. Create the static library (with the help of cmake): cmake . make make install ...

The base DirectXMath library is in the SDK include files (for example, DirectXMath.h), but the FFT routines are still separate. You can look herehttps://github.com/microsoft/DirectXMathfor the XDSP header that includes the FFT functions. However, both DirectXMath and the XDSP library ...
More details can be found in SciPy 2017 conference proceedings:https://github.com/scipy-conference/scipy_proceedings/tree/2017/papers/oleksandr_pavlyk It implements the following functions: Complex transforms, similar to those inscipy.fftpack:
first, add the following in the build.gradle (app) implementation 'com.github.wendykierp:JTransforms:3.1' and here it is the code for for transforming a simple sine wave, works like a charm double Fs = 8000; double T = 1/Fs; int L = 1600; double freq = 338; double sinValue_re...
CZT is faster in that case. Some months ago an issue was put up at Scipy's Github about the problem, see https://github.com/scipy/scipy/issues/4288 20000 prime=False padded_fft : 0.003116 numpy_fft : 0.003502 scipy_fft : 0.001538 czt : 0.035041 fftw_fft : 0.004007 --- 20011 prime=...
