Detailed Description

Frequency Attribute

Calculates a number of attributes (see below) from the frequency domain in a gate. The gate can be windowed with the window specified in the window parameter prior to the Fourier Transform. If normalize is enabled, the frequency spectra is normalized with regard to its area. This will make it possible to attribare the attribs from areas with high and low energy.

Dumptofile dumps the spectrogram at all locations to a file. This feature is only for experimental dGB use - don't present it in any manuals. If used wrong (i.e. with volume output) you will end up with a file of several Gb. The file is stored as /tmp/frequency.dump

  Frequency gate=[-4,4] [normalize=No] [window=CosTaper5] [dumptofile=No]

  Input:
  0       Real data
  1       Imag data

  Output:
  0       Dominant frequency (DFQ)
  1       Average frequency  (AFQ)
  2       Median frequency (MFQ)
  3       Average frequency Squared (AFS)
  4       Maximum spectral amplitude (MSA)
  5       Spectral Area beyond dominant frequency (SADF)
  6       Frequency Slope Fall (FSF)
  7       Absorption Quality Factor (AQF)

The system will use the algorithm specified in this function to compute the attribute's outputs. The results will be stored as different series in the DataHolder output.

Parameters

output
relpos
t0
nrsamples
threadidx	thread identifier that may be handy when using multiple threads.
