    \preliminary

    \brief The QAudioEncoderControl class provides access to the settings of a media service that
    performs audio encoding.

    If a QMediaService supports encoding audio data it will implement QAudioEncoderControl.  This
    control provides information about the limits of restricted audio encoder options and allows
    the selection of a set of audio encoder settings as specificed in a QAudioEncoderSettings
    object.

    The functionality provided by this control is exposed to application code through the
    QMediaRecorder class.

    The interface name of QAudioEncoderControl is \c com.nokia.Qt.QAudioEncoderControl/1.0 as
    defined in QAudioEncoderControl_iid.

  Returns the list of supported audio sample rates, if known.

  If non null audio \a settings parameter is passed,
  the returned list is reduced to sample rates supported with partial settings applied.

  It can be used for example to query the list of sample rates, supported by specific audio codec.

  *\a continuous is set to true, otherwise *\a continuous is set to false.
