| typedef void(^ AEIOAudioUnitRenderBlock)(AudioBufferList *_Nonnull ioData, UInt32 frames, const AudioTimeStamp *_Nonnull timestamp) |

Variable Documentation
| NSString* const _Nonnull AEIOAudioUnitDidSetupNotification |
Setup notification.
This is broadcast when the unit is setup, or re-setup after changing parameters or after a media services reset. After this notification is sent, the audioUnit property will be non-NULL.
| NSString* const _Nonnull AEIOAudioUnitDidUpdateStreamFormatNotification |
Stream update notification.
This is broadcast when the stream format updates (sample rate/channel count). If sample rate has changed for an output-enabled unit, this block will be performed between stopping the unit and starting it again.
