Switching to microphone input allows VU-meters listen and indicate ambient sounds. Turn this on if you play music by other hardware - VU-meters will follow it's level. Switching to output connects VU-meters to internal device sound output. It allows VU-meters follow only to music played by this device. This can not work properly on some Snapdragon processors with some third party players cause they use specific hardware features. Author of this program is not responsible if VU-meters don't show music level on output but on microphone do show.

Some software music players do not give author, album and song name. In this case static sentence "no music info" will be shown. Same will be shown if no any music playing but program just animates sound from microphone.

Program DOES NOT contain any malicious code - no advertising, no data acquisition, no trading, no third side communications, nothing except it really does - just front-panel for music player.

Program works only in landscape mode. It blocks automatic screen blackening but allows turn off screen by device power button. Just turn on music and run this program while charging your phone or tablet - and enjoy nice view instead of black screen.
