TrebleRange Property

Summary

Gets the treble equalization range for the audio input.

Syntax

C++

public double TrebleRange { get; }

Public ReadOnly Property TrebleRange As Double

public: 
property double TrebleRange { 
   double get(); 
}

Property Value

A value that represents the range of treble equalization for the audio input.

Remarks

This value is the absolute value of the limits. For example, a value of 1.0 means that the range is from -1.0 to 1.0.For more information, refer to the Microsoft documentation for IAMAudioInputMixer.get_TrebleRange.
