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