Music Visualization for MPD

Posted: December 23rd, 2011 | Author: | Filed under: Code, Linux | Tags: , , , | No Comments »

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.

Features:

  • Nifty VU-style level meter displayed using OpenGL/SDL
  • Configurable color schemes

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

Added the following to ~/.xmodmaprc to swap the functionality of the left control key and the caps-lock key:

!
! Swap Caps_Lock and Control_L
!
remove Lock = Caps_Lock
remove Control = Control_L
keysym Control_L = Caps_Lock
keysym Caps_Lock = Control_L
add Lock = Caps_Lock
add Control = Control_L

Load the above with the following command (which I put in my ~/.config/openbox/autostart.sh):

xmodmap ~/.xmodmaprc
