PeppyMeter is a software VU Meter written in Python. It was originally developped as the new 'VU Meter' screensaver for Peppy Player. With minor modifications it became a stand-alone application. PeppyMeter gets audio data from media players (e.g. mpd) via fifo and displays current volume level in a Graphical User Interface in a form of traditional VU Meter.
