Guide
Frequency bands tell you what’s speaking. Dynamics tell you how hard it’s speaking over time. Envelopes, builds, breaks, and drops are how you turn a flat reactive toy into a video that breathes with the arrangement.
Overall loudness (or band RMS) is excellent for slow scene intensity — fog, exposure, background mix, tunnel depth. It’s a poor solo driver for rhythmic punctuation, because sustained basslines keep the “hit” channel permanently open.
An envelope shapes how a band’s visual parameter rises after a hit (attack) and falls afterward (release).
Song sections change the rules. Breaks strip energy. Builds raise tension (often with risers and filter opens). Drops release it. Offline waveform/bass profiles can hint where those regions live; manual markers let you force the story you want on export.
| Section | Visual tendency | Notes |
|---|---|---|
| Break | Dim, sparse, readable credits | Don’t over-flash |
| Build | Tighten, zoom, streak, hold titles | Save the ceiling for the drop |
| Drop | Impact, scale, mode intensity | Budget big accents |
| Lead-in / punch / stabs | Short accents | One-shots, not permanent chaos |
COMMERD can auto-suggest arrangement markers from bassline + kick structure (break, lead-in, drop, build-up, punch, stabs). You refine them on the waveform, then modes and meta can react to section energy — not only instantaneous loudness.
Load a track with a clear drop and try Auto-map, then tweak.
Loudness is continuous level. An onset is a detected start of an event — useful for flashing exactly when a snare cracks.
No. Pick a hero reaction (scale, bloom, storm) and keep supporting layers secondary so the picture stays readable.
Not always — band listening alone can shine. Markers help when the arrangement story matters more than bar-to-bar energy.
