-    \example audio-visualizer-qml
-    \title Qt 3D: Audio Visualizer Example
-    \ingroup qt3d-examples-qml
-    \brief Demonstrates combining Qt 3D rendering and Qt Quick 2 elements.
-
-    \image audio-visualizer-qml-example.png
-
-    \e Audio Visualizer demonstrates how to implement an application that combines the use of
-    Qt 3D rendering with Qt Quick 2D elements. The example uses media player to play music and it
-    visualizes the magnitude of the music as animated bars.
-
-    \include examples-run.qdocinc
-
-    \section1 Qt Quick 2D Implementation
-
-    The Qt Quick Implementation in \c {audio-visualizer-qml/main.qml} of the example uses
-    \c{MediaPlayer} to play audio content.
-
-    \snippet audio-visualizer-qml/main.qml 0
-
-    The player is controlled with the \c{playButton} and c\{stopButton}. Based on the clicked
-    buttons the \c{state} of the \c{mainview} changes.
-
-    The 3D content is rendered using the \c{Scene3D} type. The state of the Audio Visualizer is
-    maintained in the \c{mainview}. It's passed on to the \c{visualizer} as it's needed for the bar
-    animations.
-
-    \snippet audio-visualizer-qml/main.qml 1
-
-    \section1 Qt 3D Implementation
-
-    The 3D elements of the example are created in
-    \c {audio-visualizer-qml/Visualizer.qml}. The camera is set to a fixed position
-    to show the visualized bars from a correct angle.
-
-    \snippet audio-visualizer-qml/Visualizer.qml 0
-
-    A \c{NodeInstantiator} is used to create the bars that visualize the magnitude of the music.
-
-    \snippet audio-visualizer-qml/Visualizer.qml 1
-
-    The \c{visualizer} also contains an \c{Entity} to show the progress. This element has a curve
-    shaped mesh and it's rotated on a level to show the progress based on the duration of the played
-    track.
-
-    \snippet audio-visualizer-qml/Visualizer.qml 2
-
-    In \c {audio-visualizer-qml/BarEntity.qml} there are animations for rotating the
-    bars and changing the bar color. The bars are rotated on a level following a ring form. At the
-    same time the color of the bars is animated.
-
-    \snippet audio-visualizer-qml/BarEntity.qml 0
-
-    \snippet audio-visualizer-qml/BarEntity.qml 1
-
-    The magnitude of each bar is read from a separate .raw file that is based on the track being
-    played. As the bars rotate around the ring the height is scaled to highlight currently played
-    position. After a full round of rotation, a new value is fetched for the bar.
