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

• GCC 10.1
• Clang 11.0
• VS 2019 16.8

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".

# install build tools
sudo apt-get install build-essential git cmake

# install dependencies
sudo apt-get install libobs-dev libfftw3-dev libfftw3-3

# clone repo
git clone --recurse-submodules https://github.com/phandasm/waveform.git

# build in subfolder
mkdir waveform/build
cd waveform/build

# build
cmake ..
make
make install

Prerequisite: OBS packages from RPM Fusion (see OBS Wiki).

sudo dnf install @development-tools cmake obs-studio-devel fftw-devel

git clone --recurse-submodules https://github.com/phandasm/waveform.git
mkdir waveform/build
cd waveform/build

cmake ..
make
make install

If you install OBS from Flatpak, you must install Waveform from Flatpak as well:

flatpak install flathub com.obsproject.Studio.Plugin.waveform
