The spectral slice window comprises:
-
modifying spectral parameters (click on the button, see details farther below).
-
indicating the color of the spectrum by means of a colored button at the right
of the spectrum.
-
announcing to the user whether or not the spectrum is calculated. The square is
colored if the spectrum is calculated and erased if the spectrum is not
calculated.
The left button of the
mouse allows the calculation and display of the spectral slices indicating the
appropriate portion of the spectrogram window. Moving the mouse in the spectral
slice window helps to know the frequency and energy levels at the location of
the mouse. Attention is drawn to the point that opening of the spectral slice
window modifies the actions associated with the mouse in the main window and
renders temporarily unusable some commands of the main window menu.
The 8 available spectra
The spectral parameters
Each of the 8 available spectra can be parameterized as follows.
Common parameters
- display: for deciding whether to calculate (and display) the spectrum
or not.
- pre-emphasis: for pre-emphasizing the signal before the spectral
calculation.
- level: for choosing the display level of the spectrum in the slice
window.
specific spectral parameters: They depend on the particular spectrum
considered: For more explanation on the terms appearing in the parameters,
refer to lexicon.
