public event EventHandler<ObsAudioLevelsEventArgs>? AudioLevels

Returns

EventHandler<ObsAudioLevelsEventArgs>

Occurs when OBS Studio sent new levels of the audio of the inputs that are on the air (twenty times a second, as long as they change). It is only raised when the model was asked to follow them ( with ).

Remarks

The levels are a stream, not a history: what matters is how loud it is now. When the handlers of the application are slower than OBS Studio, the levels that came meanwhile are not raised one by one: the event is raised once with the newest levels, and Ended has every input that stopped being listed in between. The levels never wait in the queue of the other notifications of the model, and never fill it. A message that says what the previous one said (a silence that stays silent) is not raised.

It is raised on the lane of the other notifications of the model: one at a time, never while another notification is being raised, on NotificationContext (or a thread of the thread pool). Its place in that lane is the place of the first message that came after it was last raised, so it can come after the notification of a change that happened after that message. The PropertyChanged event of each input (Levels) follows it. The levels are not told by Changed.
