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)
• 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, slow-swirling nebula, kaleidoscope,
a beatbox crew whose mouths articulate the track, a neon oscilloscope
stacking its own past, a spinning turntable wearing your artwork, and a
night skyline whose windows are the equalizer, and a rhythm-game note
highway where every hit lands exactly on the beat, and a custom neon
sign flickering with the track, and a cassette whose reels empty and
fill as the track plays, and a field of light motes drifting and
twinkling with the mix, a eurorack panel whose knobs follow the bands
while its cables hang in front, and 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 and its transition — 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
• The shape of your track, named: intro, build, drop, groove, break,
outro — trims, media boundaries and scene boundaries snap to them
• 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, 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
• Find the drop: the app spots the most energetic passages and lands your
teaser on them
• 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
