\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 specified 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.

\fn QAudioEncoderControl::supportedSampleRates(const QAudioEncoderSettings &settings = QAudioEncoderSettings(),

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.
If the encoder supports arbitrary sample rates within the supported rates range,
*\a continuous is set to true, otherwise *\a continuous is set to false.
