What is an After Effects Audio Spectrum Visualizer?

The audio spectrum in After Effects is a visual representation of the frequencies in an audio track. It can be used to analyze and identify sounds, as well as to find problems with the sound quality of a recording. However, it's mostly used as a visual effect in video clips as it helps create stunning effects that dance to the beat. Audio spectrums can be created using a number of different methods, but the most common is to use a Fourier transform.

How to Create Audio Spectrum with Bars in After Effects
