Libvisual
Libvisual is an abstraction library that fits between applications and audio visualization plugins. Audio visualization plugins or programs that create visuals, depend on a player or something else; basically, there was no general framework that enabled application developers to easily access interesting audio visualization plugins. Libvisual provides an interface between plugins and applications; through this interface, applications can access plugins. Since the drawing is done by the application, it also enables the developer to draw the visual anywhere desired. Currently Libvisual is mainly focused on Unix-like systems including FreeBSD, Linux, and NetBSD. The goal is to make Libvisual a cross-platform audio visualization framework. Other examples of audio visualization programs are Winamp Advanced Visualization Studio and MilkDrop. Libvisual is released under the LPGL-2.1-or-later and is included in every major Linux distribution. Media Players that support Libvisual include:
 Amarok
 XMMS2
 Beep Media Player
 BMPx
 LiVES Video Editing System
 Rhythmbox
 Trinity-amarok (revival of Amarok 1.4)

Libraries that support Libvisual include:
