Audio Waveform controls

Adjust the following controls for the Audio Waveform effect:

Audio Layer

Specifies the audio layer you want to display as a waveform.

Note: Audio Spectrum uses the audio source footage without time-remapping, effects, stretch, or levels. To graph this information, pre-compose the audio layer before applying the effect.

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.

Random Seed (Analog)

Specifies a starting point for randomizing the effect. Random Seed starts the randomizing at a different point, changing the appearance of the waveform.

Inside Color, Outside Color

Specifies the inside and outside colors of the waveform.

Waveform Options

Specifies how to display a stereo audio waveform. Mono combines the left and right channels of the audio layer. Non-stereo audio layers play as Mono.

Display Options

Specifies how to display the audio waveform. Digital displays each sample as a single vertical line connecting the minimum and maximum source sample. This option simulates the display used on digital equipment. Analog Lines displays each sample as a line connecting the previous and next sample from either the minimum or maximum audio source sample. This option simulates the retrace seen in the display of an analog oscilloscope. Analog Dots displays each sample as a dot representing either the minimum or maximum audio source sample.
