Chapter 9. Designing with Audio > Creating Graphics and Audio

Creating Graphics and Audio

Although it’s not known as a robust audio tool, After Effects has some interesting audio capabilities. In fact, it can generate tone-based sounds and create graphic elements that animate in response to sounds. All of this is made possible through the use of effects.

Audio Spectrum

Many designers want to actually see their audio on the canvas. This is especially true for those designing userinterface-style graphics or for projects where audio is a featured element. One great effect is the Audio Spectrum effect, which generates graphic lines that scale based on the frequencies present. The effect is limited to a single audio track (Figure 9.5), but you can pre-compose multiple audio tracks together if needed.
