X Multimedia System (XMMS) is a multimedia application that lets you play audio files (.mpeg and .wav files) and audio compact discs (CDs). You can play CDs by inserting them in the CD-ROM drive. You can fast forward and rewind in the same track or play different tracks on a CD. The shuffle and loop features let you play a play list of audio files or tracks on a CD in random order, or repeat continuously. The volume and balance tools let you increase or decrease the play volume for audio files and CDs, and change the volume distribution between the right and left speakers. For information about creating and editing a play list of audio files, see "Editing the play list."
