Red Giant Trapcode Sound Keys (Download)

Red Giant Trapcode Sound Keys allows you to trigger animations with audio, creating audio-intensive animations. It's designed for use with After Effects and doesn't require the need to hand-tweak keyframes. Scale, rotate, and move to the beat. Sound Keys applies as a regular effect, analyzes your audio, and generates keyframes that you can easily link to your layer's animation properties. You'll be able to select parts of an audio track in the visual spectrum and convert them into keyframes, syncing footage with audio using amplitude or frequency ranges.

Sound Keys can also be used to trigger other visual effects. For example, combine it with Trapcode Particular to have particles emitted based on a drumbeat. Isolate a snare drum hit as the trigger, or just let the general volume drive the effect.
