Spectral Slice

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.
