Image backdrop, neon, no texts
A pixel-art retro living room with a big TV and speakers as the dimmed backdrop, no artwork. The aurora preset with the arch fully risen, a wide drifting gradient, full reflection and bloom, glow, zoom blur and lens pump, no texts. A chiptune and lo-fi gaming look.

About this template

Shape and layout

A shallow arched baseline sits near the bottom of the frame, with two thin glowing arc lines riding just under it and a comb of very fine vertical bars standing on top. The right half is an exact mirror of the left, so the two centre bars always match. The title sits above the arch, with no other fixed chrome beyond an optional cover tile and progress bar.

Motion

Every bar follows one smoothed low-frequency contour that only rises and falls with the music, gated so quiet passages leave a bare tick along the baseline; there is no rotation, colour cycling, trails or per-bar jitter. Whether the low notes sit at the outer edges of the arch or meet in the middle depends on the frequency layout, and the reflection glow shimmers gently on its own clock.

Look and colour

Aurora, ember and ultraviolet gradient presets colour the bars and their reflection, or three custom colours plus a background colour replace them; a reference preset strips bloom, grain, vignette and tone mapping back to a flat two-colour original. Your own backdrop photo or video can sit behind the arch, tinted and run through a graded blur, with a soft glow flash on every kick.

What you can customize

Every setting below is yours to change in the editor, with the live preview updating as the track plays.

Visualizer

Arch curve: How high the arch bows in the middle. At zero it flattens into a straight baseline.
Arch position: Moves the whole arch up or down the frame; the artwork moves to whichever side has more room.
Arch width: How much of the frame the arch spans, centred. The bars keep their spacing, so a narrower arch has fewer of them.
Arc line weight: Thickness of the two glowing lines under the bars. At zero the lines disappear and only the bars remain.
Arc / bar gap: How far above the arch lines the bars start.
Bar density
Bar width
Bar height
Baseline ticks: The small marks left where a band is quiet, so the row never disappears completely.
Reflection
Reflection softness
Color preset: A ready-made colour scheme; pick Custom to choose your own colours.; AuroraEmberUltravioletDefaultCustom
Gradient color 1
Gradient color 2
Gradient color 3
Background color
Gradient spread: How tightly the colours are packed across the frame — higher repeats the palette more times.
Gradient drift: How fast the colours slide sideways along the arch. Zero holds the palette in place.
Bar glow: The tight halo of light right at the bars, drawn together with the spectrum. Higher widens it.
Bloom: How far the light from the bright parts spills out over the rest of the frame. Zero leaves the light only where the glow puts it.
Film grain: Adds fine film-like noise over the frame for a textured, less digital look.
Vignette
Frequency layout: Whether the low notes sit at the outer edges of the arch or meet in the middle.; Lows outsideLows inside
Audio reactivity: How strongly the visualizer moves with the music — lower for calmer motion, higher for a punchier response.
Attack: How quickly the visualizer responds when the sound gets louder.
Release: How quickly the visualizer settles after the sound drops.
Contour smoothing: Blends neighbouring bars together — low leaves a spiky comb, high draws one flowing outline.
Energy gate: How loud a band must be before its bar rises — higher keeps quiet bands down at the baseline.
Bass gate: How far the arch collapses when there is no bass — at zero it stays up through every quiet passage.
Beat flash: A brief brightness flash on each kick-drum hit.
Progress bar: OnOff
Time labels: Shows the elapsed and total time of the track.; OnOff

Background

Background photo
Background video
Background blur: Softens the background photo or video so it reads as a backdrop, not the subject.
Background dimming: Darkens the background photo or video so the visualizer and text stay readable.
Background tint strength: How strongly the background is tinted with the tint colour. Zero leaves it untinted.

Backdrop effects

Effects for your photo or video backdrop, shared by every template.

Zoom pump: How much the background photo or video zooms in on the bass. Zero keeps it at a fixed size.
Travel: How far the background photo or video wanders around the frame as the track plays. Zero holds it still.
Camera shake: A short camera shake on every kick — a vibration with a slight roll — plus a low rumble with the level. Zero holds the camera still.
Shockwave: Ripple rings spread out from the centre on the kicks and warp the picture as they pass. Zero never fires.
Lens: A lens bulge that pumps on the kicks, with a colour fringe in the outer frame that grows with the level.
Zoom blur: Radial streaks shoot out from the centre on the kicks, as if the camera rushed in. Zero never streaks.
Glow pulse: A soft bloom around the bright parts of the picture that swells on the kicks.
Light leaks: Warm patches of light drift slowly over the picture, brighter the louder the music — a film look.
Light rays: Shafts of light from the top-left corner, blocked by the darker parts of the picture, brighter with the music and flaring on the kicks. Zero keeps them off.
Light sweep: A soft, slanted band of light crosses the picture once a bar — or, without the track’s analysis, on a strong kick every few seconds at most. Zero never sweeps.
Lens flare: Long horizontal streaks of bluish light stretch out of the brightest parts of the picture on the kicks, and rest faintly in between. Zero keeps them off.
Fog: Slow drifting mist over the picture, thicker toward the bottom and breathing gently with the music. Zero keeps the air clear.
Particle overlay: A layer of drifting particles over the picture that brightens with the music.; OffDustBokehSnowSparksRainFirefliesConfettiBubblesStars
Particle amount: How many particles fill the frame.
Rain on glass: Raindrops on a pane in front of the picture: small beads, and bigger drops that slide down and bend the picture. Zero keeps the glass dry.
Echo: The previous frame lingers, slightly enlarged, so motion leaves trails and the kicks pull you into a tunnel.
Neon edges: The picture's own outlines traced in cycling neon colours, brightest on the kicks.
Glitch: Digital bursts on the kicks: sliced rows jump sideways, blocks freeze and the colour channels split. Zero never fires.
Pixelate: The picture breaks into square blocks on the kicks and sharpens again within a quarter of a second. Zero keeps it sharp.
Beat pulse: The picture breathes in time with the music, swelling and glowing just before each beat so it lands on it. Needs the track’s analysis.
Perspective tilt: Tilts the picture like a card in 3D, swaying slowly with the music and nodding on the kicks, with a light that follows the turn. Zero keeps it face-on.
Liquid: The picture ripples like a liquid surface, more strongly the louder the music. Zero keeps it flat.
Flash: A short flash toward white on the strongest kicks, at most two per second. Zero never flashes.
Retro VHS: Tape look: a gentle wobble, colour bleed, scan lines, noise and a tracking band that rolls through on the beat.
Old film: Projector look: flicker, hair scratches, dust, a gentle weave and a sepia lean.
Backdrop grain: Adds fine film-like noise over the frame for a textured, less digital look.
Color grade: A colour treatment over the whole picture — and the colours of the built-in backdrop when you set no photo or video.; NaturalWarmCoolMonoFaded
Duotone: Maps the picture’s light and shade onto two colours, dark to light. Custom uses the two colours you pick below.; OffMidnightSunsetForestGoldRoseCustom
Duotone shadows: The colour the darkest parts of the picture turn into.
Duotone highlights: The colour the brightest parts of the picture turn into.
Motion follows: What the camera moves follow — zoom pump, shake, tilt, shockwave, lens, zoom blur, liquid, depth, subject pop and focus. A stem needs the track’s stems.; Whole mixDrumsBassVocals
Light follows: What the light follows — glow, flashes, light leaks, rays, sweep, lens flare, fog, vignette, spotlight, rim light and hue steps. A stem needs the track’s stems.; Whole mixDrumsBassVocals
Texture follows: What the texture effects follow — glitch, pixelate, VHS, echo trails, neon edges, particles, rain on glass and subject ghost trails. A stem needs the track’s stems.; Whole mixDrumsBassVocals
Drop: The picture tightens, dims and drains of colour over the bars before a drop, then bursts open on it. Needs the track’s analysis.
Follow the song: Calmer reactions in the quiet parts of the song and bigger ones in the loud parts, easing at each change. Needs the track’s analysis.
Hue drift: The colours slowly cycle around the hue wheel and take a step on every kick. Zero keeps them as they are.
Depth parallax: Sways the near parts of the photo more than the far ones, and swells them on the kicks, so a flat picture gains depth. Needs the photo's depth map: off until it is ready, and on a video.
Focus rack: Blurs by depth like a lens: at rest the near part is sharp and the far part soft, and the focus pulls to the background and back on the kicks. Needs the photo's depth map; off until it is ready.
Depth fog: A pale haze over the far parts of the picture that breathes with the music, so the near parts stand out. Needs the photo's depth map; off until it is ready.
Keep subject crisp: Keeps the photo's subject untouched while blur, glow, echo, tape, grade and grain go to the background only. Needs the photo's subject map; off until it is ready.
Subject rim light: A neon rim of light hugging the photo's subject, with a soft halo behind it, flaring on the kicks. Needs the photo's subject map; off until it is ready, and on a video.
Subject ghost trails: Pale copies of the subject linger and drift outward with the music while the background stays put. Needs the photo's subject map; off until it is ready, and on a video.
Subject pop: The photo's subject swells toward the viewer on the kicks while the background holds still. Needs the photo's subject map; off until it is ready, and on a video.
Subject spotlight: Darkens the picture around the subject, like a spotlight that follows it and breathes with the music. Needs the photo's subject map; off until it is ready, and on a video.
Beat sync: Lands the stepping effects — the kaleidoscope, the hue drift and the shockwave rings — on the beat or the bar instead of on every bass hit. Needs the track’s analysis.; OffEvery beatEvery bar
Focus pulse: The picture softens and dims as the music settles and snaps sharp and bright on the hits. Zero keeps it steady.
Vignette pulse
Mirror: Folds the picture into mirrored copies. The kaleidoscope turns slowly and steps on the kicks.; OffLeft-rightFour-wayKaleidoscope
Particles behind subject: Spreads the particles through the scene's depth, so some pass behind the photo's subject. Needs the photo's depth map; off until it is ready, and on a video.; NoYes
