    \brief Wrapper for equalizer utility.

    \since 10.1

    Playback wrapper provides Qt style interface to the audio equalizer

    utilities. Its implementation is hidden using private class data pattern.

    This class defines several APIs that are needed from \a MpPlaybackView

    and other components in \a mpplaybackviewplugin.

    \fn MpEqualizerWrapper::equalizerReady()

    This signal will be emitted when Audio Eqalizer is initialized. This is

    when all APIs, like \a applyPreset, are ready to be used.
