GetFreqDBArray
The GetFreqDBArray method obtain the amplitude of a set of
frequencies(FFT result set).
Function GetFreqDBArray([out] FreqArray as variant)
As Long
Parameters
- FreqArray [out]
- a array of float.
Return Values
- If GetFreqDBArray succeed, it return the number of elements
in the FreqArray, Otherwise return 0.
Remarks
FreqArray[index] will return the
amplitude of frequency=index*SamplingRate/2*(numbers_element_FreqArray-1)
If you want obtain the amplitude of the single frequency, you may use GetfrequencyDB
instead.
