# pulseviz

... is going to be a light-weight configurable OpenGL-accelerated audio visualizer for PulseAudio written in C++11. It is supposed to supersede my older [pulseviz.py](https://github.com/pckbls/pulseviz.py) Python project as it turned out, Python might be a bit too slow for this kind of application.
