Notes the code needed to play MP3 files, so you have to translate MP3s into a supported format, such as
WAV, before you can play them. You can, however, download the source code for Rhythmbox
and XMMS and build the applications with MP3 support.

Notes The Ogg Vorbis format can also be used for compressed audio files as Ogg Vorbis
is a patent- and royalty-free format.

6.1.4 Burning a CD

Today, most GUI file managers have the ability to burn CDs.

Example: Nautilus File Manager and Xandros File Manager have incorporated features
to burn CDs.

Linux distributions also come with standalone GUI programs that enable you to easily burn CDs
and DVDs.
For example, K3b is a popular CD/DVD burning application for KDE that’s available in Knoppix
and SUSE.
Most of the CD burning applications are easy to use. Basically, we collect the files that we want to
burn to the CD or DVD and then the burning process is started. Obviously, for this to work, your
PC must have a CD or DVD burner installed.
The K3b window’s upper part is for browsing the file system to choose what you want to burn
onto a CD or DVD. The upper-left corner displays the CD writer device installed.
To burn a CD, we begin with one of the projects displayed in K3b window’s lower part.

Example: New Audio CD Project, or New Data DVD Project.
Finally, you are required to add files and burn the project to the CD or DVD. This is done by
selecting Projectz→ Burn or pressing Ctrl+B. For an audio CD, you can drag and drop MP3 files
as well as audio tracks.
To burn CDs, K3b needs the external command-line programs cdrecord and cdrdao. K3b also
needs the growisofs program to burn DVDs.
If an error is encountered regarding missing cdrdao , ensure that your system is connected to the
Internet and then type apt-get install cdrdao to install it.

and performing image manipulation tasks, like image composition, photo retouching, and
image creation.

z z Gnome Ghostview (GGv): It is a graphical application which is capable of displaying
PostScript files.
