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
Side Options
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
Audio Waveform effect
Apply the Audio Waveform effect to a video layer to display the audio waveform of a layer that contains audio (and
optionally video). You can display the audio waveform in several different ways, including along an open or closed
mask path.
Note: Audio Waveform uses the audio source footage without time-remapping, effects, stretch, or levels. To display the
spectrum with such effects, precompose the audio layer before applying the Audio Waveform effect.
To prevent masks on the layer from clipping the output of the Audio Waveform effect, set their mask modes to None.
(See "Mask modes" on page 377.)
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
The lowest and highest frequencies, in hertz, to display.
Inside and outside colors of the bands.
Specifies that overlapping spectrums are blended.
