Audio-reactive video composition

Use this skill to turn an approved audio source into an auditable cue map and then into bounded visual behavior. The central contract is:

$$ \text{source audio} \rightarrow \text{measured features} \rightarrow \text{confidence-bearing cues} \rightarrow \text{reviewed anchors} \rightarrow \text{deterministic visual timeline} $$

Do not equate a detector output with editorial meaning. An onset is not automatically a beat, cut, drop, or lyric accent; an acoustic cluster is not automatically a verse or chorus.

Evidence stance

• Documented fact: behavior stated by official analysis libraries, standards, or cited research.
• Production heuristic: a practical mapping that must be tested on the track and audience.
• Empirical observation: a measured result from the supplied audio, analyzer run, render, or playback.

Analysis algorithms, defaults, and model behavior are volatile. Facts were verified 2026-07-12. Pin the decoder, library, model, parameters, and random seeds used for each production.
