AudioObjectPropertySelector
Declaration
typealias AudioObjectPropertySelector = UInt32Discussion
An AudioObjectPropertySelector is a four char code that identifies, along with the AudioObjectPropertyScope and AudioObjectPropertyElement, a specific piece of information about an AudioObject.
The property selector specifies the general classification of the property such as volume, stream format, latency, etc. Note that each class has a different set of selectors. A subclass inherits its super class’s set of selectors, although it may not implement them all.
