Managing Spectrogram Settings

This procedure describes how to set the default values for the calculation parameters of a spectrogram, such as the window type and FFT size.

To Manage Spectrogram Settings:

  1. Click File > Preferences to display the Preferences dialog box.
  2. Select the Time-frequency tab to display the current default settings for the time-frequency window.
  3. In Default time-frequency domain calculation settings:
    1. Select the default Window Type to use for spectrogram calculation and display.
    2. Select the default FFT size to use for spectrogram calculation and display.
    3. Specify the value for the Overlap rate to specify the degree of overlapping between successive windows on which the spectrogram is calculated.
  4. Click OK.

The default settings for spectrogram calculation are now defined, and will be used as the default calculation parameters when calculating a spectrogram.
