Original (top left), and with effect applied (bottom left and right)
Audio Layer The audio layer you want to use as input.
Start Point, End Point Specifies the position at which the spectrum starts or ends if Path is set to None.
Path The audio spectrum is displayed along the path of the layer, unless None is chosen.
Use Polar Path The path starts from a single point and appears as a radial graph.
Start Frequency, End Frequency The lowest and highest frequencies, in hertz, to display.
Frequency Bands The number of frequency bands into which to divide displayed frequencies.
Maximum Height Maximum height, in pixels, of a displayed frequency.
Audio Duration Duration of audio, in milliseconds, used to calculate the spectrum.
Audio Offset Time offset in milliseconds used to retrieve the audio.
Thickness Thickness of the bands.
Softness How feathered or blurry the bands appear.
Inside Color, Outside Color Inside and outside colors of the bands.
Blend Overlapping Colors Specifies that overlapping spectrums are blended.
Hue Interpolation If the value is greater than 0, the frequencies displayed rotate through the hue color space.
Dynamic Hue Phase If selected, and the Hue Interpolation is greater than 0, the Start color shifts to the maximum
frequency in the range of displayed frequencies. This setting allows the hue to follow the fundamental frequency of
the spectrum displayed as it changes.
Color Symmetry If selected, and the Hue Interpolation is greater than 0, the start and end colors are the same. This
setting allows color continuity on closed paths.
Display Options Specifies whether to display frequency as Digital, Analog Lines, or Analog Dots.
Side Options Specifies whether to display the spectrum above the path (Side A), below the path (Side B), or both
(Side A & B).
Duration Averaging Specifies that audio frequencies are averaged to reduce randomness.
Composite On Original If selected, displays the original layer with the effect.
