Struct AudioUnitParameterOptions 

#[repr(transparent)]
pub struct AudioUnitParameterOptions(pub u32);

Bit positions 18, 17, and 16 are set aside for display scales. Bit 19 is reserved.

This flag provides a hint to a host that this parameter should be controlled through the highest resolution if the host has limitations on the control resolution of parameter values. Generally this means that controlling this parameter with a single MIDI Control message (i.e. 128 values) is too course a grain for that parameter, and a finer control resolution should be used if possible. If this flag is not set, then a host can assume that a 7-bit control quantization is acceptable. Ideally, parameters should be controlled in the fullest resolution that they are published with.

Changing the parameter in real-time will cause a glitch or otherwise undesirable effect.

If set, the parameter can be ramped.

If set, the parameter is obscure (hint to UI to only display in expert mode).

In the original ParameterInfo a C string only was specified. With MacOS 10.2 and later, the last four bytes of this string are reserved for a CFStringRef, which gives the ability to used Unicode encoding, necessary for providing a name in languages using non-ASCII characters. If this flag bit is set, the CFStringRef is valid.

If set, changing this parameter may change any number of others in the AudioUnit.

If set, changing this parameter may change others in the same element as the current parameter.
