Rondo - Music Visualizer

You just finished a track. You need a teaser for Instagram, a Canvas for Spotify, a video for YouTube — now, not next week.

Rondo turns your audio into animated visuals, directly on your phone. No upload, no account, no server: your unreleased master stays with you. It works in the studio with no signal, and on a plane.

WHAT IT DOES
• Analyses your track on the device (kick, mids, highs, spectrum, tempo)
• 25 scenes that genuinely react to the music: console bars, a ring that pulses on the kick, a heat-map spectrogram, VU meters, particle bursts, a tunnel, a lava lamp, a nebula, a beatbox crew whose singer takes the mic when your lyrics come in, a turntable wearing your artwork, a night skyline whose windows are the equalizer (Paris, London, New York, Tokyo…), a see-through cassette, a eurorack wall… — plus two stickers for your own video: a now-playing card and the track's waveform
• Scenes in 3D: the turntable, the VU meters and the cassette are real objects, lit like in a studio — the arm follows your track, the reels wind on. Bars and Orb go 3D too. You choose the angle; the view stays put
• 21 backgrounds, from aurora, film grain and vinyl grooves to a synthwave sunset, sparks thrown by every kick and your artwork breaking into grains on the drop — two of them light (paper, halftone), turning the whole palette over — plus a CRT effect and a film finish (bloom, halation, grain) over everything
• Release kit: one tap renders the teaser on the drop, the Spotify Canvas looping on it and the full YouTube video. Send a track from another app or a Shortcut and it lands on the kit
• Share straight to an Instagram Story or Reel when the export is done
• Media: your own photos and videos, one after another over the track, each with its effects, its grade and its transition — a film cut to your music. Or start from a video: its sound becomes the track, its picture stays in sync behind the scene, and four scenes take it as their material — Multicam, Echo, Prism, Colour map
• A scene timeline: one scene on the intro, another on the drop, each with its own settings and a crossfade at the join
• Auto edit: one tap writes both timelines from what your track already knows — a scene for each part, cuts on the downbeat, effects dosed by section. All of it editable afterwards
• The shape of your track, named — intro, build, drop, groove, break, outro — and its tempo: find the drop lands your teaser on the build, and cuts and loops land on the bar
• Live mode: the scenes on the sound of the room — a studio session, a set, a party. Nothing is ever recorded, and over HDMI the visuals move to a TV or a projector. Free
• Room mode: the crowd scans a code, and every phone in the room plays your look to the music it hears, all in time. No network, no account. Free
• Synced lyrics: transcription on the device, a karaoke sweep, and a proofread by your phone's own language model
• Your identity: artwork, title and artist name burned in, eight typefaces, entrance animations, ten signed palettes, your brand colour — or the colours of your artwork
• Widget mode: the scene in a movable frame, your photo or video around it
• Waveform trimming and fades; exports in 9:16, 1:1, 16:9 and Spotify Canvas
• Presets: six curated looks to start, and yours reused on every release in one tap
• Set mode: chain your projects full screen and project them on a TV (AirPlay, HDMI) — or export the whole set as one video, with YouTube chapters ready to paste
• Backup to YOUR iCloud — not to our cloud
