A OpenGL music visualizer. GLMViz currently supports FiFo buffers and PulseAudio as input.
The main focus of this project is to create a high framerate, dB correct spectrum audio visualizer.
More examples are in the Example folder.
GLMViz is NOT a lightweight program as it's build using GLFW and other OpenGL abstraction libraries.
- OpenGL libraries:
libglfw,libglm - FFT library:
fftw - PulseAudio[Optional]:
libpulse - Configuration library:
libconfig++
Additionally CMake 3.0.2 / Meson and a C++11 compatible compiler are needed to successfully build the project.
The install script automatically creates a build folder, handles configuration, etc...
Runnig the install script will install GLMViz to /usr/local/bin/ and copy the default config to /etc/GLMViz/config
./install
Per-user configurations have to be copied manually using:
cp /etc/GLMViz/config ~/.config/GLMViz/config
glmviz [path-to-config]
Exit with CTRL-C or by closing the window.
The config can be reloaded by pressing R or by sending SIGUSR1 to the program.
Big thanks to dpayne and Karl Stavestrand for the pulseaudio setup code. Also thanks to xdaimon and kritzikratzi for the smooth line shader idea.
