Description
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.
Features
- Cross-platform Available for Mac OS X and Windows XP systems
- See It, Hear It Sound Keys' 32-band adjustable spectrum has an easy-to-use visual interface
- Happy Endings Choose from Instant, Linear or Exponential falloff controls to alter the generated keyframes
- What's the Frequency The adjustable range controls let you choose up to 3 frequency ranges for sampling
- Adobe CS3 support Sound Keys is fully compatible with After Effects CS3.
Highlights
Visual interface for audio selection
Sound Keys displays sound as a 32-band adjustable audio spectrum, making it easy to isolate the part of the sound you'd like to use in an animation.
Integrate sound with other effects
Since it is applied as a regular effect within After Effects, Sound Keys can be used to make audio trigger other visual effects. For example, combine Sound Keys with Trapcode Starglow to animate the intensity of light based on a drumbeat.
Multiple instance capability
Create mesmerizing, complex animations by using the same audio track to drive several types of animation, selecting different audio frequencies for each effect.
Examples
Airbase
Sound Keys was first used to extract three separate streams from the bass region of the audio spectrum. Then three instances of 3D Stroke were used to create the "strings." Each has an animated path that describes a vibrating string. 3D Stroke's Path Time (found under the Advanced controls) was used to control the movement of the strings. Each has an expression where a sine function describes the general movement of the string. This is then multiplied by the stream that Sound Keys extracted, so that the strings appear to vibrate with their corresponding frequency.
Beat Explode
This example shows how you can link the output of Sound Keys to Trapcode Particular's Particles/sec setting. The effect causes particles to be emitted on each kick-drum beat. Note that you need good bass to properly hear the kick drum — a laptop speaker may not provide enough bass response.
