Apple Soundtrack Pro 3 - Manual (Page 227)

You can select parts of the audio file, apply actions, and edit the audio file in Frequency
Spectrum view in the same way as in Waveform view. In addition, you can make selections
of frequency ranges as well as copy, paste, delete, and adjust the amplitude of frequency
selections. You can also change the Frequency Spectrum view display to show the
frequency spectrum linearly or logarithmically, use different analysis windows, and change
the number of samples used to calculate the view.

µ
Choose View > File Editor Display > Show Waveform.

Using the Spectrum View HUD
The Spectrum View HUD is a floating window that provides extensive controls for
Frequency Spectrum view.
• Preemphasis slider and value field: Applies gain per octave. Higher values emphasize
high frequency content.
• Minimum Frequency slider and value field: Allows you to view a subset of the frequency
range (for example, only the frequencies over 1 kHz).
• Maximum Frequency slider and value field: Allows you to view a subset of the frequency
range (for example, only the frequencies under 9 kHz).
• Minimum Power slider and value field: Defines the bottom of the scale (where the blue
portion of the gradient starts).
• Maximum Power slider and value field: Defines the top of the scale (where the red portion
of the gradient ends).
