[EditorAttribute(System.Type, System.Type)] 
public AudioProcessors SelectedAudioProcessors { get; }

Public ReadOnly Property SelectedAudioProcessors As Leadtools.Multimedia.AudioProcessors

public: 
property Leadtools.Multimedia.AudioProcessors^ SelectedAudioProcessors { 
   Leadtools.Multimedia.AudioProcessors^ get(); 
}

Property Value

A AudioProcessors object representing the audio processor collection.

Remarks
