+ @abstract API's to allow macOS apps to participate in audio routing arbitration.
+
+ @discussion
+ Audio routing arbitration is a feature of Apple operating systems for automatically connecting wireless headphones
+ to the best audio source device in a multi-product environment. The supported Apple products are iOS devices,
+ iPadOS devices, watchOS devices, and Mac computers. The best audio source is the device from which the user is
+ most likely to want audio playing. The operating system tries to determine that device intelligently. For example, if a
+ user was playing a movie with their iPad, then locked the iPad, and started using their iPhone to play music, the iPad
+ would stop being the source audio device and the iPhone would become the source audio. This feature is limited
+ to select Apple and Beats wireless headsets.
+
+ The intention of the API is to give a hint to the operating system that the app is about to start audio and
+ to provide context about what type of audio is to be used. To be a participant of the routing arbitration the app has
+ to begin the arbitration. Once arbitration completes, the application is free to start running audio I/O. The result of
+ arbitration may change the system default input and/or output audio devices, so the use of this API will affect any applications
+ that are impacted when system default devices change. When the app is no longer interested in using audio I/O it should
+ leave audio routing arbitration.
+
+ Applications that use the AVAudioRoutingArbiter API are encouraged to also use MPRemoteCommandCenter and
+ MPNowPlayingInfoCenter classes provided by Media Player framework. The use of those classes provides the operating system
+ additional context about the content being played and allow the application to respond to remote command events.

+ @discussion
+ When an app wants to participate in automatic audio arbitration for the wireless headphones route, it has to begin arbitration
+ specifying its arbitration session category. It provides the operating system time to arbitrate with other nearby Apple
+ devices to obtain ownership of supported Bluetooth audio devices. Then upon completion of arbitration, the operating system
+ will automatically determine whether to route audio to the nearby Bluetooth device. Once arbitration completes, the application
+ is free to start running audio I/O. I/O will be started upon the app request even if the -beginArbitrationWithCategory:completionHandler: fails.
+ This method should also be used whenever restarting audio I/O in order to allow the system to arbitrate for ownership of a Bluetooth
+ device that may have been taken by another nearby Apple device during the time that I/O was stopped.
