Hi.

git clone --recursive https://github.com/xdaimon/music_visualizer.git
cd music_visualizer/
mkdir build
cd build
cmake ..
make -j4
./main

Depends on opengl >= 3.3, and pulseaudio.

Uses code from the following repositories
ffts (linkotec fork) fast fft library
cava pulseaudio setup code
Oscilloscope shader code for drawing smooth lines

Checkout the 'Feature Toggles' fold in pulse.cpp!
