    \title Guitar Tuner Example
    \example demos/mobile/guitartuner

The Guitar Tuner application can be used to tune guitar strings by analyzing the
audio recorded by the device microphone. Guitar Tuner can be also used in the
listening mode. It will then play the audio by the corresponding frequency, and
the user can tune the guitar by ear. The application demonstrates the audio-in
and the audio-out interfaces of
\l{external: Mobility Multimedia}{Qt Mobility Multimedia} and integrating Qt
code to the Qt Quick UI.

    The example is hosted in Projects Forum Nokia: https://projects.forum.nokia.com/guitartuner

\note This demonstration requires QtMobility libraries.
