Visual Basic (Declaration) 
Public Property MixLevel As Double
Visual Basic (Usage)Copy Code
Dim instance As AudioInputs
Dim value As Double
 
instance.MixLevel = value
 
value = instance.MixLevel
C# 
public double MixLevel {get; set;}
C++/CLI 
public:
property double MixLevel {
   double get();
   void set (    double value);
}

Property Value

0.0 to 1.0 Expected range of recording volume level where 0.0 indicates the recording level is off (muted) and 1.0 indicates full volume. -1.0 Automatic gain adjustment; the recording level is adjusted automatically.
