<p>Phonon is a cross-platform multimedia framework that enables the use of audio and video content in Qt applications. The <a href="phonon-overview.html#phonon-overview">Phonon Overview</a> document provides an introduction to the architecture and features included in Phonon. The <a href="phonon.html">Phonon</a> namespace contains a list of all classes, functions and namespaces provided by the module.</p>
<p>Applications that use Phonon's classes need to be configured to be built against the Phonon module. The following declaration in a <tt>qmake</tt> project file ensures that an application is compiled and linked appropriately:</p>
<pre class="cpp"> QT += phonon</pre>
<a name="qt-backends"></a>
<h2>Qt Backends</h2>
<p>Qt Backends are currently developed for Phonon version 4.1&#x2e; The Phonon project has moved on and introduced new features that the Qt Backends do not implement. We have chosen not to document the part of Phonon that we do not support. Any class or function not appearing in our documentation can be considered unsupported.</p>
