Phonon is a cross-platform multimedia framework that enables the use of audio and video content in Qt applications. The Phonon Overview document provides an introduction to the architecture and features included in Phonon. The Phonon namespace contains a list of all classes, functions and namespaces provided by the module.

Applications that use Phonon's classes need to be configured to be built against the Phonon module. The following declaration in a `qmake` project file ensures that an application is compiled and linked appropriately:

     QT += phonon

To include the definitions of the module's classes, use the following directive:

     #include <phonon>

The Phonon module is part of the Qt Desktop Edition and the Qt Open Source Edition.
