.. cpp:class:: OcaAudioLevelSensor: OcaLevelSensor

    Child of  **OcaLevelSensor** that returns an audio meter reading in dB relative to a known reference level, and whose value has been calculated by the selected averaging algorithm.

    **Properties**:

    .. _ocaaudiolevelsensor_classid:

    .. cpp:member:: static const OcaClassID ClassID = "1.1.2.2.1"

        Number that uniquely identifies the class. Note that this differs from the object number, which identifies the instantiated object. This property is an override of the  **OcaRoot** property.

        This property has id ``5.1``.

    .. _ocaaudiolevelsensor_classversion:

    .. cpp:member:: static const OcaClassVersionNumber ClassVersion = 2

        Identifies the interface version of the class. Any change to the class definition leads to a higher class version. This property is an override of the  **OcaRoot** property.

        This property has id ``5.2``.

    .. _ocaaudiolevelsensor_law:

    .. cpp:member:: OcaLevelMeterLaw Law

        Enum that defines metering algorithm, including averaging characteristics and, in some cases, reference level. Readonly in some objects.

        This property has id ``5.1``.

    **Methods**:

    .. _ocaaudiolevelsensor_getlaw:

    .. cpp:function:: OcaStatus GetLaw(OcaLevelMeterLaw &law)

        Gets the value of the Law property. The return value indicates whether the property was successfully retrieved.

        This method has id ``5.1``.

        :param OcaLevelMeterLaw law: Output parameter.

    .. _ocaaudiolevelsensor_setlaw:

    .. cpp:function:: OcaStatus SetLaw(OcaLevelMeterLaw law)

        Sets the value of the Law property. The return value indicates whether the property was successfully set. Only implemented for objects whose Law property is read/write.

        This method has id ``5.2``.

        :param OcaLevelMeterLaw law: Input parameter.
