Decibel Audio Player is a GTK+ open-source (GPL) audio player for GNU/Linux. It is very straightforward to use thanks to a clean and user-friendly interface. It is especially targeted at Gnome and follows the Gnome HIG.
Decibel Audio Player is built around a highly modular structure that lets the user disable completely the features he does not need. A disabled feature uses absolutely no memory and no processor time.
Decibel Audio Player is a real audio player and does not include features that are not meant to be part of an audio player. These features, such as tagging files or burning CDs, generally have a better support in dedicated software. If you are looking for an audio player that can make coffee, then you should stay away from Decibel and give a try to other players (e.g., Amarok, Exaile).
