Trapcode Soundkeys is a plugin for After Effects that analyzes your audio and generates keyframes you can easily link to your layer's animation properties. Scale, rotate, and move to the beat. Or use audio to drive effects.
Sound Keys can be used to trigger other visual effects. For example, combine Trapcode Sound Keys 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.
Select parts of an audio track in the visual spectrum and convert them into keyframes, syncing footage with audio using amplitude or frequency ranges.
