================================

Class Hierarchy:

:ref:`OcaRoot <ocaroot>` : :ref:`OcaManager <ocamanager>` : :ref:`OcaAudioProcessingManager <ocaaudioprocessingmanager>`

.. cpp:class:: OcaAudioProcessingManager: OcaManager

    Placeholder for optional manager that in future versions of the standard
    will hold various global audio processing parameters.

     - May be instantiated at most once in any device.

     - If instantiated, object number must be 9.



    **Properties**:


    .. _ocaaudioprocessingmanager_classid:

    .. cpp:member:: static const OcaClassID ClassID = "1.3.9"

        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 ``1.1``.

    .. _ocaaudioprocessingmanager_classversion:

    .. cpp:member:: static const OcaClassVersionNumber ClassVersion = 3

        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 ``1.2``.
