. Audacious was the default audio player in
Ubuntu Studio in 2011-12, and was the default music player in Lubuntu until October 2018, when it was replaced with
VLC.
History
Audacious began as a
fork of Beep Media Player, which itself is a fork of
XMMS. Ariadne "kaniini" Conill decided to fork Beep Media Player after the original development team announced that they were stopping development in order to create a next-generation version called BMPx. According to the Audacious home page, Conill and others "had

own ideas about how a player should be designed, which
heywanted to try in a production environment."
Since version 2.1, Audacious includes both the
Winamp-like interface known from previous versions and a new,
GTK-based interface known as ''GTKUI'', which resembles

to some extent. GTKUI became the default interface in Audacious 2.4.
Change to C++ and Qt
Before version 3.0, Audacious used the GTK 2.x
toolkit by default. Partial support for GTK3 was added in version 2.5, and Audacious 3.0 has full support for GTK3 and uses it by default. However, dissatisfied with the evolution of GTK3, the Audacious team chose to revert to GTK2 starting with the 3.6 release, with long-term plans of porting to
Qt.
Since August 8, 2018, the official website has HTTPS enabled site-wide and
GTK3 support was dropped completely.
As version 4.0, Audacious is using Qt as its primary toolkit but the GTK 2.x support is still available.

Plug-ins
Audacious owes a large portion of its functionality to
plug-ins, including all
codecs. More features are available via third-party plug-ins.
Current versions of the Audacious core classify plug-ins as follows (some are low level and not user-visible at this time):
* ''Decoder plug-ins'', which contain the actual codecs used for decoding content.
* ''Transport plug-ins'', which are lowlevel and implemented by the VFS layer.
* ''General plug-ins'', which provide user-added services to the player (such as sending tracks with
AudioScrobbler)
* ''Output plug-ins'', which provide the audio system backend of the player.
* ''Visualization plug-ins'', which provide visualizations based on

* ''Effect plug-ins'', which provide various sound processing on the decoded audio stream
* ''Container plug-ins'', which provide support for playlists and other similar structures.
* ''Lowlevel plug-ins'', which provide miscellaneous services to the player core and are not categorized into any of the other plug-ins.
* Output plug-ins:

Skins
Audacious has full support for
Winamp 2 skins, and as of version 1.2, some free-form skinning is possible. Winamp .wsz skin files, a type of Zip archive, can be used directly, or can be unarchived to individual directories. The program can use Windows Bitmap (.bmp) graphics from the Winamp archive, although native skins for Linux are usually rendered in
Portable Network Graphics

Clients
Audacious is intended to be a standalone media player not a server (unlike XMMS2), though it accepts connections from client software, such as
Conky.
Connection to Audacious for remote control can be done over plain
DBus, by using an
MPRIS-compatible client, or using the official Audtool utility created just for this purpose.
