1FCD-OpBSD (also known as Karma BSD) is a one-floppy OpenBSD MP3 player with functionality to mount NTFS, UDF (on DVD, CDROM, or external file), EXT2FS, NFS, MFS, and MSDOS file systems. It plays MP3 tracks, and can copy files from any disk to any disk. The software may be useful for the blind and it can also be used as a unique utility for copying files over a network (via NFS) or from any file system known to OpenBSD. USB sticks can be mounted as well. Static OpenBSD binaries can be made on other systems and used with Karma BSD.
Aqualung is an advanced music player originally targeted at the GNU/Linux operating system, and also running on FreeBSD, OpenBSD, and Microsoft Windows. It plays audio CDs, Internet radio streams, and podcasts as well as sound files in just about any audio format, and has the feature of inserting no gaps between adjacent tracks.
Bonk is an audio compression program that can operate in either lossy or lossless mode. In lossy mode, it achieves around 14:1 compression while remaining perceptually lossless; equivalent to around 95 kbps for CD quality stereo. In lossless mode, which allows exact recovery of the original audio file, the compression ratio is typically around 2:1. The compressed files are stored in a new format based on speech compression techniques. Compressed files can then be converted back to an uncompressed format or played back in real time.
DarkIce is a live audio streamer. It records audio from an audio interface (e.g. a sound card), encodes it, and sends it to a streaming server. DarkIce can record from OSS audio devices, ALSA audio devices, Solaris audio interfaces, and Jack sources. DarkIce can encode into MP3, MP2, Ogg Vorbis, and AAC formats, and can send the encoded stream to ShoutCast, IceCast 1.3.x and 2.x, and the Darwin Streaming Server.
MP3c is a curses-based audio CD-to-MP3/OGG converter with CDDB support. It can be used in an interactive menu environment or a batch mode which lets you encode automatically. MP3c tries to find the most useful information in a CDDB entry, and even recognizes sampler CDs correctly. It is very configurable and can be used with every available encoder, ripper, and tag editor. It is available in different languages (currently English, Spanish, Portuguese, Italian, Polish, and German).
MoosicApplet is a GNOME panel applet which displays the current status of the Moosic jukebox server. It also provides some basic features for controlling the song player. It features a configurable layout and the ability to rewrite the song name in various ways to make it easier to read.
Music Player Daemon (MPD) is a server that allows remote access for playing music in various formats and managing playlists. It makes a great desktop player with frontend options (Qt, GTK, ncurses, Windows, and Web clients are available). It is also appropriate as a console player that is scriptable, and is especially useful if X is restarted frequently. A set of rapid development tools for clients are being developed and include a C library, Python module, PHP class, Perl module, and Java Class. The goals are to be easy to install and use, to have minimal resource requirements, to be stable and flexible, and easy to interface.
