Waveform is an audio spectral analysis plugin for OBS Studio.
It is based on FFTW and optimized for AVX2/FMA3.
Clone the repo with submodules: git clone --recurse-submodules
Or if you already cloned without them: git submodule update --init --recursive
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".
