 The metadata specified in this OBU defines the parameter values for an algorithm for an indicated duration, including any animation of the parameter values over this duration. The metadata is used in conjunction with a corresponding parameter definition and parameter data specification. The parameter definition is specified based on [=ParamDefinition()=]. The parameter data provides the values to apply in each parameter block. These are specified using the AnimatedParameterData() function template if parameter animation is supported.
