Function [up] [down]
Produces a 2-dimensional frequency-spectrum plot of a sample

Parameter [up] [down]
Palettegray : the display uses a grey scale palettecolor : the display utilises a high contrast colour palette
Window (W1)what windowfunction to use
Lineshow many timesslices should SFX render.
MaxLin.how many timeslices will fit on this screen.
BandsJust how many bands should SFX use. Less Bands means less math, but you lose out on accuracy.
GammaNonlinear amplification. Values from 100 % towards 0 % means enhancing quiet details.Values above 100 means hiding them. The default value of 75 % is a good choice tomake quiet signals visible too.
Modehigh 2 : four results are merged into onehigh 1 : two results are merged into onenormal : every value in the input will be used to form one resultlow 1 : every second value in the input will be used, interpolating inbetween data.low 2 : every fourth value in the input will be used, interpolating inbetween data.

Notes [up] [down]
When calculations are complete a new window is opened on which the graph is drawn. When the window is active and source-sample is playing, the playposition will be drawn into spectrogram too. Furthermode a cross follows the mousepointer.
This operator uses the Fast-Fourier-Transformation for its calculations.
