Spectrum-true waves
Each lobe reads 64 log-spaced slices of the live spectrum: kicks punch the outer bass swells while melody and air ripple toward the cover. If the outline moves, your track moved it.
Twin spectrum waves flank your cover, bass swelling at the outer edges, melody rippling in toward the artwork.
Flux is a music visualizer that draws your song as two mirrored spectrum outlines on either side of a static, centered album cover: 64 measurement points per lobe, sub-bass anchored at the outer edges of the frame and treble tapering in toward the art. Each lobe is a thin luminous stroke that breathes above and below a horizontal baseline, tinted by a six-color gradient that flows from the bass edge to the treble tip.
There is no scroll, no spin, no motion clock. Nothing on screen moves unless the music does. Hits snap the waves up instantly, peaks decay musically, a loudness envelope makes choruses swell over verses, and a soft silence gate settles both lobes to a calm flat line between sections. Your cover sits untouched in the middle: no pump, no rotation, just the release front and center.

Your cover art sits static and centered between the two lobes, with a track/artist/tagline lockup, so the waves frame the release instead of covering it.
A silence gate eases both waves down to a near-flat idle line in quiet passages, then instant attack and a loudness envelope make drops visibly tower. Clean, never busy.
The studio preview replays the exact per-frame analysis the renderer uses, so what you see while editing is what your exported video looks like.
