T.E.A.R. (pronounced Tair) is a console-based frontend for common MP3/OGG creation tools which automates all of the settings involved in ripping and encoding a CD. TEAR uses the CDDB database at freedb.org to name, organize, and add ID3 tags to each encoded file. It can use either cdparanoia or cdda2wav to rip .WAV files from the CD and it can use lame, bladeenc, gogo, or OggEnc to encode them. TEAR also supports SMP.
Sajber Jukebox is a mpeg layer 3 player with a graphical user interface. It's based on Woo-jae Jung's splay for the audio and QT's graphical library for the interface. The Jukebox maintains pointers to songs on the local system or the net, and when the user wishes to play it, it opens the location and migrates the filedescriptor to the playing process. The advantage of this scheme is that the Jukebox doesn't need to worry about playing the darn thing, and the player won't have to worry about where the song is, since it'll just see the filehandle given to it, and couldn't care less of where it originally came from.
Tunez is an MP3/Ogg jukebox that works with a voting system. You can vote for your favorite tracks via the Web interface, and the Tunez daemon will take care of the rest. It is ideal for shared work environments and LAN parties. Tunez also works equally well as an interface to an Icecast server (v2.0 is supported via Ices v0.3). Tunez makes it easy to update ID3 tags for all your MP3s. Support for grabbing Amazon art in included for all of your favorite albums. A full user/group permission scheme is available so that you can customize Tunez for your own use.
Webplay creates, from a collection of MP3s and Ogg Vorbis files (indexed from a directory or MySQL/PostgreSQL database), a Web-based jukebox with support for multiple independent streams. If Lame/oggenc are available, it can change the bitrate or codec of a file in real time to a selectable value. Each user controls their stream via a Web interface and can skip back, forward, or to a specific track; increment or decrement the bitrate; and check the current playlist, song, or bitrate. Playlists can be looped, randomized, played locally on the webserver, edited, deleted, reused, or renamed.
