.. cpp:class:: OcaFilterArbitraryCurve: OcaActuator

    An arbitrary-curve filter, with transfer function specified as amplitude and phase versus frequency.

    **Properties**:

    .. _ocafilterarbitrarycurve_classid:

    .. cpp:member:: static const OcaClassID ClassID = "1.1.1.13"

        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 ``4.1``.

    .. _ocafilterarbitrarycurve_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 ``4.2``.

    .. _ocafilterarbitrarycurve_transferfunction:

    .. cpp:member:: OcaTransferFunction TransferFunction

        Transfer function of the filter.

        This property has id ``4.1``.

    .. _ocafilterarbitrarycurve_samplerate:

    .. cpp:member:: OcaFrequency SampleRate

        Sample rate inside the filter. We can't assume it's the same as the device input or output rate.

        This property has id ``4.2``.

    .. _ocafilterarbitrarycurve_tfminlength:

    .. cpp:member:: OcaUint16 TFMinLength

        Minimum number of points that transfer function must specify

        This property has id ``4.3``.

    .. _ocafilterarbitrarycurve_tfmaxlength:

    .. cpp:member:: OcaUint16 TFMaxLength

        Maximum number of points that transfer function may specify

        This property has id ``4.4``.
