Delta VU is a simple audio visualization tool designed to monitor the audio signal level being output by MPD.
According to their project home page, “Music Player Daemon (MPD) is a flexible, powerful, server-side application for playing music. Through plugins and libraries it can play a variety of sound files while being controlled by its network protocol.” MPD has no visualization capability on its own, but provides access to audio being played using a FIFO buffer mounted in filespace. Delta VU reads this buffer and displays the data as an animated VU-style graph that follows the volume of whatever is being played.

Delta VU has been tested on Debian Linux (32 and 64 bit versions) and is available as source code only.
