11.2.2. Playing music files

11.2.2.1. mp3 files

The popular .mp3 format is widely supported on Linux machines. Most distributions include multiple programs that can play these files. Among many other applications, XMMS , which is presented in the screenshot below, is one of the most wide-spread, partially because it has the same look and feel as the Windows tool.

Also very popular for playing music are AmaroK , a KDE application that is steadily gaining popularity, and MPlayer , which can also play movies.

       Restrictions
        

Some distributions don't allow you to play MP3's without modifying your configuration, this is due to license restrictions on the MP3 tools. You might need to install extra software to be able to play your music.

In text mode, you can use the mplayer command:

11.2.2.2. Other formats

It would lead us too far to discuss all possible audio formats and ways to play them. An (incomplete) overview of other common sound playing and manipulating software:

• Ogg Vorbis: Free audio format: see the GNU audio directory for tools - they might be included in your distribution as well. The format was developed because MP3 is patented.

• Real audio and video: realplay from RealNetworks .

• SoX or Sound eXchange: actually a sound converter, comes with th e play program. Plays .wav , . ogg and various other formats, including raw binary formats.

• Playmidi: a MIDI player, see the GNU directory.

• AlsaPlayer: from the Advanced Linux Sound Architecture project, see the AlsaPlayer web site .

• mplayer : plays just about anything, including mp3 files. More info on the MPlayerHQ website .

• hxplay : supports RealAudio and RealVideo, mp3, mp4 audio, Flash, wav and more, see HelixDNA (not all components of this software are completely free).

• rhythmbox : based on the GStreamer framework, can play everything supported in GStreamer , which claims to be able to play everything, see the Rhythmbox and GStreamer sites.

Check your system documentation and man pages for particular tools and detailed explanations on how to use them.
