Returns the average power at a given frequency

Namespace: NDXVUMeterNET
Assembly: DXVUMeterNETGDI (in DXVUMeterNETGDI.dll) Version: 3.0.4021.33606 (3.1.0.0)

Syntax

C#
public double FFTAverageFromIndex(
	int fftidx,
	DXVUMeterNETGDI..::..FFTChannelConstants channel
)
Visual Basic
Public Function FFTAverageFromIndex ( _
	fftidx As Integer, _
	channel As DXVUMeterNETGDI..::..FFTChannelConstants _
) As Double
Visual C++
public:
double FFTAverageFromIndex(
	int fftidx, 
	DXVUMeterNETGDI..::..FFTChannelConstants channel
)

Parameters

fftidx
Type: System..::..Int32
The index in the transform for which we want to obtain the power for
channel
Type: NDXVUMeterNET..::..DXVUMeterNETGDI..::..FFTChannelConstants
The channel (left/right)

Return Value

The average power level at the given FFT index

Remarks

The average is calculated by averaging the values in the FFT history. The size of the history can be adjusted through the FFTHistorySize property.
