This app uses your Android phone’s LEDs to create a light show for your music

On Android devices, the popularization of active display and imitators has basically negated the need for built-in LEDs. After all, what more can a blinking light tell you than a screen? Luckily, crafty developers are finding other uses for the neglected multicolored diodes. One app for Android, LED Music Effects, turns your device’s LEDs into a basic music visualizer.

The app, which requires root access to work, reflects the rhythmic punctuation of songs on your smartphone’s built-in LEDs. As the app is currently configured, a single LED alternates between three colors (up to three work synchronously).

The developer has posted handy videos to illustrate the effect on a few different devices, one of which you can see in action below:

LED Music Effect supports a nearly endless list of music players, including but not limited to Google Music, Spotify, Rhapsody, and Poweramp. The developer has only tested the app on a few devices, namely Sony Xperia phones, but is confident it’ll work on most smartphones.

The app is listed as a free download on the Google Play Store.
