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, waveform orb, spectrogram, needle VU meters, dot rain, particle bursts, tunnel, liquid with kick ripples, lava-lamp blobs, LED equalizer with peak-hold, nebula, kaleidoscope, a beatbox crew whose mouths articulate the track, a neon oscilloscope stacking its own past, a turntable wearing your artwork, a night skyline whose windows are the equalizer, a rhythm-game note highway where every hit lands exactly on the beat, a custom neon sign, a cassette whose reels empty and fill, a field of light motes, a eurorack panel whose knobs follow the bands while its cables hang in front, slow curls of smoke drawn in the palette's own ink — plus two stickers made for your own video: a now-playing card (artwork, title, real progress) and the track's waveform with its playhead • 18 backgrounds: gradient, aurora, film grain, amp glow, waves, haze, oscilloscope sweep, vinyl grooves, retro sun-and-road, pixel dithering, hyperspace, drifting colour mesh, night bokeh, rain on a lake, warm cassette wear — and two light ones, paper and halftone print, which turn the whole palette over — plus a CRT effect over everything • Media: your own photos and videos, one after another over the track, each with its share of it, its effects, its transition, and for a clip the passage it plays — a film cut to your music, from your camera roll • 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, trims and boundaries land on the beat, and the Canvas loops on a whole number of bars • Live mode: the scenes on the sound of the room — a studio session, a set, a party. The microphone feeds the analysis in real time, nothing is ever recorded, and over HDMI or USB-C the visuals move to a TV or a projector. Free • Synced lyrics: transcription on the device, a karaoke sweep, and a proofread by your phone's own language model — the timings never move • Your identity: artwork, title and artist name burned in, four typefaces, entrance animations, ten signed palettes, your brand colour — or the colours of your artwork • Widget mode: put the scene in a movable frame and let your photo or video show around it • Waveform trimming, fade in and fade out • Exports in 9:16, 1:1, 16:9 and Spotify Canvas (a silent loop that closes on itself) • 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, screen mirroring) — 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.
