Unpack1FFT(chain, bufsize, binindex, whichmeasure=0)
Takes an FFT chain and extracts a single scalar value as a demand-rate stream. To call it, a "demander" is needed, which fires whenever the FFT chain fires - this is normally achieved using PackFFT but can also be done using Demand.
chain |
an FFT chain |
bufsize |
the size of the expected input FFT frames |
binindex |
the integer index of the bin you want to query |
whichmeasure |
0 for magnitude and 1 for phase. None of these arguments can be modulated. |
