Audio-intensive animations no longer require time-consuming hand-tweaking of keyframes. Trapcode Sound Keys, a plug-in for Adobe After Effects, makes it easy to synchronize motion and sound using either amplitude or frequency ranges. Unlike palette-based audio-sync products, Sound Keys is applied as a regular effect, making it possible to save settings with your project, generate keyframes into output parameters, and link keyframes to expressions.
