I’m guessing this is from the SC-based help where examples are embedded in documentation, but the entry for @hopsize in the fluid.bufloudness~ reference says:
How much the buffered window moves forward, in samples. By default 512 to be similar with all other FluCoMa objects, the EBU specifies other values as per the examples below.
@windowsize also has a similar reference to the EBU specifications:
The size of the window on which the computation is done. By default 1024 to be similar with all other FluCoMa objects, the EBU specifies other values as per the examples below.
Beyond not having embedded examples in the reference file in Max, it would be good to actually list what these values are, as a point of reference (e.g. “By default 512 to be similar with all other FluCoMa objects, the EBU specifies other values such as 1024, 9999, and over 9000”).
