Audio Spectrum Visualizer is a demonstration application for the UWP AudioVisualizer project that can be found here on github: https://github.com/clarkezone/audiovisualizer
The project provides developers with a XAML Control that can be plugged into MediaElement and MediaPlayer and enables standard or custom visualizations to be implemented simply using the out of box control or Win2D.
The demo app provides a simple UI that enables the opening and playback of various audio file formats showing off both the stock and custom Spectrum analyzer and VU meter controls with the graphics running smoothly at 60FPS and frame accurately in sync with the audio playback.
