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 NO SUBSCRIPTION The free version exports without a watermark. Rondo Pro is a one-time purchase that unlocks every scene and background, the 1:1, 16:9 and Canvas formats, brand identity and presets. WHO IT IS FOR Beatmakers posting snippets, independent artists on release day, podcasters and labels rebuilding the same look every week, DJs putting their sets online.
