Audio Spectrum
The Audio Spectrum effect displays the spectrum of an audio layer. It displays the magnitude of frequencies in the range you define using Start Frequency and End Frequency. This effect can display the audio spectrum in a number of different ways, including along a Bezier path of a layer. Apply the effect to a layer that contains a solid or an image, and that may contain audio.
Audio is applied to an image layer using display options of analog dots (center) and digital with a Polar path (right).
Note: This effect is a visual effect, not an audio effect, and it must be applied to a video layer.
