A music visualizer that listens
Most visualizers bounce a row of bars. This one hears the track — its kicks, its snares, the notes that stand out of the mix, its tempo — and draws scenes from them: a wormhole whose walls are the spectrum's last few bars, a supernova that throws a comet for every note, a ridgeline of the last few seconds of sound, a spirograph traced by the ratios between the notes that are sounding.
Make it yours
Pick a scene and the shape a note takes in it, fold it into a kaleidoscope, spin it, smear it back through time, then put it through the rack: split the colour channels, pixelate it, lay scan lines and grain over it, flash it on the snare. Choose a palette or your own three colours. Or press Surprise me until something stops you.
Made for posting

Frequently asked questions
Is my song uploaded anywhere?
No. The file is decoded, analysed and turned into video entirely in your browser. Nothing is uploaded, which is also why it works offline and why there is no queue.
What does it export?
An MP4 with H.264 video and AAC audio — the one format Instagram, TikTok, YouTube and every phone accept. Choose 9:16 for Reels, TikTok and Shorts, 1:1 for a feed post, or 16:9 for YouTube.
How does the visual follow the music?
It listens to the file: kicks, snares and hats from how the low, middle and top of the spectrum jump, held notes from the peaks that stand out of it, and the tempo from how regularly it all happens. The scenes are then drawn from those events and from the spectrum itself, frame by frame.
Is it free?
Yes — any length, up to the whole song. Free videos carry a small midimaker.io mark and an end card; a Pro plan removes them.
Which browsers does it work in?
Video export needs a browser that can encode MP4: the latest Chrome, Edge or Safari. Firefox can preview everything but may not be able to export.
Want full tracks, not just visuals?
The MIDI Maker studio rolls complete, editable arrangements — melody, chords, bass and drums — you can export to any DAW. Free, in your browser.
