WebFFTW is a very fast FFT C library. The way it is designed to work is by planning in advance the fastest way to perform a particular transform. It does this by trying lots of different techniques and measuring the fastest way, so called planning. WebIndicate the FFTW directory so the header fftw3.h can be read. Build options > Search directories > Compiler and specify where the header file is. To me it's C:\Program Files\FFTW. Copy the libfftw3-3.dll file from the FFTW directory to next to the .exe of your application. Tp me it's C:\projets\fftwEx\bin\Debug.

In computing, half precision (sometimes called FP16 or float16) is a binary floating-point computer number format that occupies 16 bits (two bytes in modern computers) in computer memory. It is intended for storage of floating-point values in applications where higher precision is not essential, in particular image processing and neural networks.
