abcde is a frontend to cdparanoia, wget, cd-discid, id3, and your favorite Ogg Vorbis (the default), MP3, FLAC, Ogg Speex, or MPP (Musepack) encoder. It grabs an entire CD and converts each track to the desired format, then comments or ID3-tags each file, all with one command. It supports multiple output in a single CD read, the creation of a single track from a CD, resume operation, CD concatenation, volume normalization, gapless encoding (with LAME), parallelization, SMP, proxies, customizable filename organization and munging, playlist generation, distributed encoding via distmp3, and more.
AlsaPlayer is a new PCM player written with the ALSA sound system in mind. It also includes support for JACK, OSS, NAS, and ESD.

Features include a real- time effects stream, variable speed/pitch control, SHOUTcast/icecast streaming support, multiple active visual scopes, command line mode, playlists, plugin architecture, low-latency mode, and more.
cdenc lets you encode whole audio CDs in a special directory which can be burned on CDROM afterwards. It tries to extract all necessary informations for the mp3info tags from the CDDB. It also produces HTML files using wish, including the coverpicture of the disc, tracks.idx files for the sajber jukebox, long filenames for a conventional player, and bitmaps with the cd titles for usage with the Yamakawa/Raite MP3 player AV715. cdenc makes it easy to produce MP3 CDs which work fine with Sajber Jukebox, WinAmp, and Yamakawa the same time.
Chango is a system for cacheing MP3 files from multidisc cdrom drives. Since you can't actually mount different discs in the same physical device simultaneously, this software will cache the files you need off to a predetermined cache, so that all of the needed files will be available simultaneously.
DigitalDJ is an SQL-based MP3-player frontend designed for people who want to create an MP3 version of their CD collection. It is designed to work with the Grip ripping/encoding application (but can be used separately). When Grip encodes MP3 files, it will place all of the song information into an SQL database. DigitalDJ can then use this information to create playlists based on a number of criteria.
