Waveform is an audio spectral analysis plugin for OBS Studio.
It is based on FFTW and optimized for AVX2/FMA3.

Waveform's only external dependency is libobs.
You'll need to build obs-studio separately and point CMake to it when building Waveform.
From the CLI interface, the latter can be accomplished via -DCMAKE_PREFIX_PATH="path/to/obs-studio/build_x64/libobs".
You may also need to point to the w32-pthreads library as well, which is under "path/to/obs-studio/build_x64/deps/w32-pthreads".
mkdir build && cd build
cmake ../
Double-click generated .sln file in build directory. When VisualStudio loads, go to "Build -> Build Solution" or Ctrl-Shift-B
Copy waveform.dll and waveform.pdb to C://Program Files/obs-studio/obs-plugins/64bit/
Copy contents of "data" folder ("locale" folder and "gradient.effect" in waveform source directory) to C://Program Files/obs-studio/data/obs-plugins/waveform/
