isEnabled
Determines whether the bus is active.
Declaration
var isEnabled: Bool { get set }Discussion
Hosts must enable input busses before using them. This allows an audio unit to be prepared to render a large number of inputs, but avoid the work of preparing to pull inputs which are not in use.
This version 3 property is bridged to the version 2 kAudioUnitProperty_MakeConnection and kAudioUnitProperty_SetRenderCallback APIs.
