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 mask path along which to display the audio spectrum.
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.
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.)
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
