VU Meter – Linux – Standalone

meters

PeppyMeter is a software VU Meter written in Python. It was originally developed 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 the form of a traditional VU Meter.
