Spectrograms can be configured in a variety of specifications. Some frequently selected configurations are such as shown before:
In order to create a Wide-Band-Spectrogram with fundamental frequency contour measurement and formant extraction data select FFT-Spech-FOR from the STx-function tree and adjust the settings as shown.
The user is encouraged to specify the spectrogram parameters (frequency resolution, hop size etc.) and a spectrogram configuration found to be approriate to his sound material under current consideration. Both configurations shown above are just typical "Narrow-Band" for overview in musical signals and "Broad-Band" for speech analysis. Nevertheless STx doesn't the user to be restricted to any pre-configurations.
