OutputVolumeGet method
Remarks
Retrieves the current volume. The volume can be changed through the OutputVolumeSet method.
Syntax
[Visual Basic]
Public OutputVolumeGet (
nScaleType as enumVolumeScales
) as float
[C#]
public float OutputVolumeGet (
enumVolumeScales nScaleType
);
[C++]
public: float OutputVolumeGet (
Parameter
Description
nScaleType
The volume scaling type.
Supported values are the following:
Mnemonic constant
Value
Meaning
SCALE_LINEAR
0
The returned volume is based upon a linear scale and can be in the range from 0.0 (silence) to 100.0 (max volume)
SCALE_LOG
1
The returned volume, expressed in dB, is based upon a logarithmic scale and can be in the range from -100 (silence) to 0 (max volume)
The actual applied formula for converting a linear volume into a logarithmic volume is the following:
VolumeInDB = 20 * log10 (VolumeLinear/100)
The C syntax for converting a logarithmic volume into a linear volume is the following:
VolumeLinear = 100 * pow (10, VolumeInDB/20);
Return value
Negative value
An error occurred (see the LastError property for further error details)
>= 0
The current volume
