EasyPMP is a program used to create and maintain the music database on a variety of portable music players. This allows tracks to be browsed by artist, album, genre, etc., rather than by directory structure. The following devices are supported: iRiver H100 series; iRiver H300 series; iRiver H10 UMS; iRiver H10 MTP (with emergency connect mode); iRiver H10Jr. UMS; iRiver U10 UMS; MEDION MDJuke220 and MDJuke 440; and Samsung YH-820, YH-920, and YH-925. It is developed as part of a project called PMPlib, which aims to develop a library that can be used by desktop media players and other programs, in order to support these devices.
XMMS2 is a redesign of the XMMS music player. It features a client-server model, allowing multiple (even simultaneous!) user interfaces, both textual and graphical. All common audio formats are supported using plugins. On top of this, there is a flexible media library to organize your music.
The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
Mp3tag is an Objective-Caml library for reading and writing ID3v1 and v2 tags in MP3 files. It includes mp3tag tools, which can be used to modify tags in MP3 files or rename files according to their tags, and a cddbtag tool that modifies tags by using a CDDB server to retrieve information about the track.
Music Manager is a Konqueror plugin that lets you standardize the filenames of your music files, guess information and set ID3 tags from the file's name (this can be done to several files in one shot), rename many selected files based on their ID3 tags, set ID3 tags in mass for selected files with options for copying ID3s from other files and leaving some ID3 fields untouched, rename _ to space and vice versa, create HTML and text indexes of your collections (including total playing time, etc., configurable through templates), create nice CD covers with full listings of your music files (also configurable through templates), and organize your music collection to create a CD.
