Spectrum analyser (FFT)
The Spectrum Analyser uses FFT (Fast Fourier Transform) to display a
continuous frequency graph, allowing for very precise and detailed real-
time frequency analysis.
The current frequency spectrum will be shown as a red graph (by default).
Spectrum “peaks” (recent maximum values) will be shown as a purple graph. All
colors can be adjusted in the Settings dialog as described below.
By clicking the camera icon, you can take a snapshot of the current spectrum.
This will be superimposed on the current peak spectrum graphs, in a color you
can customize (by default, a white graph), until you click the camera icon again (to
take a new snapshot). One use for this is to check the effects of adding EQ, etc.
Zooming
You can adjust the frequency scale and range in the Settings dialog as de-
scribed below, but it’s also possible to temporarily zoom in on a frequency
area of interest. This is done by clicking and dragging a rectangle in the
Spectrum display – when you release the mouse button, the display is
zoomed in so that the enclosed frequency range fills the window. To return
to full-scale display, select “Zoom-out fully” from the Options pop-up menu.
