DeaDBeeF is a lightweight modular audio player with high customization capabilities. It supports a variety of audio formats, such as MP3, OGG, FLAC, APE, WAV, as well as chiptune formats like NSF and SID. The program allows for conversion between these formats and offers a user interface that can be adjusted according to user preferences. Additionally, its functionality can be expanded through additional plugins.
Among its features, it stands out for supporting cuesheets, reading and writing tags (such as ID3v1, ID3v2, APEv2), and streaming online radio (protocols like shoutcast/icecast).
The name "DeaDBeeF" is a reference to the hexadecimal number 0xDEADBEEF, commonly used in operating systems as a "magic number" to identify specific areas in memory. This characteristic reflects its technical origin and attachment to the developer community.
