Inside Color, Outside Color Specifies the inside and outside colors of the bands.
Blend Overlapping Colors Specifies that overlapping spectrums are blended.
Hue Interpolation If value is greater than 0, the frequencies displayed rotate through the hue color space.
Dynamic Hue Phase When selected, and the Hue Interpolation is greater than 0, the Start color shifts to the
maximum frequency in the range of displayed frequencies. This allows the hue to follow the fundamental frequency
of the spectrum displayed as it changes.
Color Symmetry When selected, and the Hue Interpolation is greater than 0, the start and end colors are the same.
This 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 When selected, displays the original layer with the effect.
Audio Waveform effect
Apply the Audio Waveform effect to a video layer to display the audio waveform amplitude of an audio layer. You
can display the audio waveform in a number of different ways, including along a Bezier path created by an open or
closed mask of a layer.
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.
This effect works with 8-bpc color.
Original (left), and with effect applied (center and right)
Adjust the following controls for the Audio Waveform effect:
Audio Layer Specifies the audio layer you want to display as a waveform.
Start Point, End Point Specifies the position at which the waveform starts and ends, if Path is set to None.
Path If set to None, the audio waveform is displayed along the path of the layer.
Displayed Samples Specifies the number of samples to display in the waveform.
Maximum Height Specifies the maximum height, in pixels, of a displayed frequency.
Audio Duration Specifies the duration of audio, in milliseconds, used to calculate the waveform.
Audio Offset Specifies the time offset in milliseconds used to retrieve the audio.
Thickness Specifies the thickness of the waveform.
Softness Specifies how feathered or blurry the waveform appears.
