      • AVAudioEngineConfigurationChangeNotification

        @NotNull
public static @NotNull java.lang.String AVAudioEngineConfigurationChangeNotification()
        [@constant] AVAudioEngineConfigurationChangeNotification A notification generated on engine configuration changes when rendering to/from an audio device. Register for this notification on your engine instances, as follows: ``` [[NSNotificationCenter defaultCenter] addObserver: myObject selector: @selector(handleInterruption:) name: AVAudioEngineConfigurationChangeNotification object: engine]; ``` When the engine's I/O unit observes a change to the audio input or output hardware's channel count or sample rate, the engine stops itself (see `AVAudioEngine(stop)`), and issues this notification. The nodes remain attached and connected with previously set formats. However, the app must reestablish connections if the connection formats need to change (e.g. in an input node chain, connections must follow the hardware sample rate, while in an output only chain, the output node supports rate conversion). Note that the engine must not be deallocated from within the client's notification handler because the callback happens on an internal dispatch queue and can deadlock while trying to synchronously teardown the engine.

@Deprecated
public static @NotNull java.lang.String AVAudioSessionInterruptionWasSuspendedKey()
        Deprecated.
        Only present in begin interruption events, where the interruption is a direct result of the application being suspended by the operating sytem. Value is a boolean NSNumber, where a true value indicates that the interruption is the result of the application being suspended, rather than being interrupted by another audio session. Starting in iOS 10, the system will deactivate the audio session of most apps in response to the app process being suspended. When the app starts running again, it will receive the notification that its session has been deactivated by the system.
