Audio-reactive animation.

Use measured audio levels to drive the size or movement of a graphic.

The disc responds directly to the decoded voice’s amplitude. Its dependency graph reads the audio layer at the current time, allowing the animation to follow another recording without manually retiming pulses.

Use this prompt as a starting point. Review the result, then ask for the details you want to change.

A prompt to start from

Use Strata. Design a restrained voice-reactive Mirage poster. Use the packaged original eight-second voice and a large Sea disc over a pale fixed halo. Drive both scale axes from audioGainBoth using a 90 ms measurement window; keep the left headline stable and generous. During silence the disc should relax, and during speech it should visibly swell. Do not hand-keyframe the pulses.

A few useful details.

Does this find musical beats automatically?

This feature uses measured audio levels. Beat detection and the timing decisions built from it are separate steps.

How do I try this with my agent?

Copy the prompt into your supported local agent with Strata installed. Review the preview, then ask for the changes you want. The composition stays editable as you refine it.

Where does the video render?

Strata previews and renders locally on an Apple Silicon Mac. The local engine is free; your agent’s subscription or usage costs are separate.
