Summary

Gets the selected audio processor collection object.

Syntax

C++

public Leadtools.Multimedia.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

The AudioProcessors object is used to build a list of audio processing filters to use during the conversion process. See AudioProcessors object for more details on processor collections.
