Circular Spectrum wraps the frequency spectrum into a ring around the centre of the canvas. With the album cover slotted in the middle, it turns any static artwork into a pulsing animated artefact — the format that defines lyric videos and Spotify Canvas loops.
Each radial segment corresponds to a frequency band. As the track plays, segments extend outward from the inner radius, creating a halo of motion that hugs the cover image. Beat detection and bass weighting let the ring breathe with the song.
The cover is optional — without it, you get a clean radial visualizer suitable for animated logos, podcast intros, or product launches. With it, the scene becomes the single most reusable promotional asset for any music release.
Tune the inner radius, bar length, rotation speed, glow, and ring outline opacity for everything from a tight, focused look to a sprawling cosmic halo.
