AudioVizSDL is a realtime oscilloscope, vu meter, spectrum and voiceprint audio visualization.
originally i wrote this software as a plugin for gstreamer in linux, but finally found time to port it to windows and added opengl support. now the rendering is hardware-accelerated.
here's a video demonstration of AudioVizSDL in action:
