About this app

Music VU gives you beautiful and dynamic level, wave, and spectrum displays for your music, right on your home screen. Works with any music player on your phone or tablet (with Android-imposed limitations on some devices, see below). You can place a variety of meter and visualizer widgets anywhere on your home screen. Change colors, mix them up, resize/enlarge, or use more than one side-by-side for greater impact. Turn on microphone audio in settings to visualize your voice or music playing in the room.

All segmented meters feature classic digital styling and a high-resolution first meter segment. In addition, specialty spectrum analyzer and waveform displays give you unique ways to visualize your music. Premium spectrum and waveform displays are free for a 7 day trial period (level meters are always free).

To find the visualizer widgets long-press an empty part of your home screen, choose Widgets and look for “Music VU”. On some devices open your apps list “Widgets” section to find widgets. To make widgets big: long-press, release, then resize in both directions.

Note: This is an advanced widget app which uses special techniques to update quickly. Due to limitations in the way Android widgets work you should have a fairly fast phone or tablet for good performance. You may still notice irregular or slow updates. Avoid using more than 5 visualizer widgets at the same time unless your device can handle it. To minimize CPU and battery usage Music VU is not active unless your screen is on and music is playing or microphone is enabled and picking up sounds.

Note: There are problems with some newer phones which break visualizers, including Music VU. A different music player may work, try Phonograph or YouTube Music, or connect a Bluetooth speaker/headset. If needed you can enable the microphone in settings. If you have any problems, for example your combination of Android device and music player doesn't work, please email support at musicvu@georgielabs.net. We'll try to help resolve your problem.

Microphone Permission: All Android visualizers need microphone permission to work (see https://developer.android.com/reference/android/media/audiofx/Visualizer). Our app does not store or transmit any audio.
