Mp3blaster is an interactive text-based program that plays several audio file types (MP3, Ogg Vorbis, wav, and sid). It is one of the few audio players for the text console that allows full interactive control during playback. One of its key features is the ability to compose a very flexible playlist (while playing!). It plays most MP3 formats and has full mixer support built in.
Umix is a program for adjusting sound card volumes and other features in sound card mixers. You can control your volumes, balances, and recording sources flexibly from the command line or with a ncurses user interface with familiar vi/emacs keybindings. Umix supports multiple mixer devices. All settings can be saved and loaded from a file.
Xmmix is an audio mixer utility for the X window system using the OSF/Motif interface. It works with the Linux sound driver as well as any UNIX system running the Open Sound System (OSS) driver. Xmmix is user-friendly and has the ability to save/retrieve mixer settings to/from files.
XVolume is a simple Xlib volume control that mimics the traditional OSD (on screen display) controls found in various appliances. It is intended to be launched by a shortcut key (eg. one of the "Internet" buttons on your keyboard) and one can then directly adjust the volume by user-defined keys. It was inspired by a similar feature in the Windows driver for a Logitech keyboard. Xvolume is highly configurable and can be tailored for a perfect fit with your window manager.
MP3 STATION is a LIRC-aware, plain-text tool set for managing MP3 playback in a car or home with as little user interaction as possible. It can restart the last playlist at the last played track/frame, transparently load directories, transparently recompile playlists, and keep a repository of all the playlists. It also has two simple clients for communicating with cm3s (a curses console client and a very basic one on a parallel port). All programs run under a non-privileged user account.
Mixxx is software for DJs that provides everything needed to create live mixes. It allows you to beatmatch songs and crossfade them together, like you would with turntables and a mixer. It runs without any extra hardware, and offers a wide range of advanced features including comprehensive MIDI controller and vinyl control support. To obtain the lowest latency and highest responsiveness, it uses hardware video acceleration and takes advantage of multi-core CPUs.
