Class AUAudioUnitBusArray

  • All Implemented Interfaces:
    NSFastEnumeration, NSObject
    public class AUAudioUnitBusArray
extends NSObject
implements NSFastEnumeration
    AUAudioUnitBusArray Container for an audio unit's input or output busses. Hosts can observe a bus property across all busses by using KVO on this object, without having to observe it on each individual bus. (One could add listeners to individual busses, but that means one has to observe bus count changes and add/remove listeners in response. Also, NSArray's addObserver:toObjectsAtIndexes:forKeyPath:options:context: is problematic; it does not let the individual objects override the observation request, and so a bus which is proxying a bus in an extension process does not get the message.) Some audio units (e.g. mixers) support variable numbers of busses, via subclassing. When the bus count changes, a KVO notification is sent on "inputBusses" or "outputBusses," as appropriate. Subclassers should see also the AUAudioUnitBusImplementation category. The bus array is bridged to the v2 property kAudioUnitProperty_ElementCount. API-Since: 9.0
