Spectrogram Options Dialog

• To open the Spectrogram Options dialog, click Edit Settings.

  

The following options are available:

Color Scheme

Allows you to customize the color scheme for the frequency levels in the Spectrogram and the Wavelet display.

• To change the color scheme for different frequency levels, move the color markers with the mouse.

• To change the color of a marker, right-click it and select a new color.

• To create a new color marker, double-click on the color bar.

Magnitude Range

Allows you to specify the spectral amplitude range that you want to display in the Spectrogram and the Wavelet display.

Opacity of Selection

Allows you to specify the opacity of the selection in the Spectrogram or the Wavelet display.

Frequency Scale

Allows you to select the scale on which the frequency spectrum is displayed in the Spectrogram. If Log is selected, the frequency spectrum is displayed on a logarithmic scale, thus spacing the octaves equally. This comes closest to the perception of pitch of the human ear. Mel, Bark, and ERB are psycho-acoustic scales.

FFT Bands

Allows you to adjust the trade-off between temporal resolution and frequency resolution in the Spectrogram. If you specify a higher value, more frequencies are analyzed but they are located less accurately in the time domain.

FFT Window

Allows you to select the shape that most effectively reduces the artifacts of the audio analysis.

Wavelet Bands

Allows you to set the number of bands per octave for the Wavelet display.

Presets

Allows you to save and restore presets for spectrum process settings.
