DeaDBeeF

DeaDBeeF is a modular cross-platform audio player for GNU/Linux, macOS, Windows, *BSD, OpenSolaris, and other UNIX-like systems. It plays a wide range of audio formats, including MP3, Ogg Vorbis, FLAC, APE, WAV, M4A/M4B/MP4, MPC, TTA, CD audio, chiptune formats, tracker modules, and additional formats via FFMPEG. It reads and writes tags across ID3v1, ID3v2, APEv2, Xing/Info, and VorbisComments, with automatic character set detection for non-Unicode tags and full Unicode support. Cuesheet support handles embedded and external files with charset detection and conversion, and chapter information can be extracted from formats such as M4B audiobooks and OGG files.

The player includes a tag editor with custom fields, multiple playlists via tabs or a playlist browser, and Title Formatting scripting compatible with Foobar2000 for sorting and grouping tracks. Audio processing includes an 18-band graphical equalizer, DSP plugins, and a customizable DSP pipeline, along with gapless playback and Replaygain with a scanner. Album art can be loaded from image files or audio file tags, with optional automatic downloading from web services. Streaming radio is supported for MP3, OGG, AAC, and WMA over Shoutcast/Icecast and MMS protocols. The Converter plugin transcodes files with preprocessing options such as downsampling and equalizer application, title formatting for naming, and optional folder structure preservation. The player is extensible through plugins and customizable in its UI. Linux and Mac builds are distributed under GNU GPL 2, with most code under the ZLIB license.
