Audio Visualizer – High-Resolution Audio Visualization Tool

I built a free and open-source, high-resolution, real-time audio visualizer on the web.

What it does

In the maker’s words, at launch

I built a free and open-source, high-resolution, real-time audio visualizer on the web.

It’s open source under AGPL-3.0. Feedback is welcome! GitHub: https://github.com/charliethompson217/audiovisualizer
