Audio Visualizer

Audio Visualizer generates on-screen visuals driven by audio that is playing locally on an Android device. As a track plays from files stored on the device, the application reads the signal and animates in response to it, so the display follows the music rather than looping a fixed pattern.

The scope is local media playback, meaning files already on the handset rather than streaming services. That keeps the application self-contained but also means it will not react to audio coming from remote sources or other apps unless the device makes that signal available. It is published by Rino-program under the MIT license and targets Android only. Anyone looking for a desktop visualizer or a plugin for an existing media player will need to look elsewhere; this is a standalone mobile application.
