Why an online visualizer beats installing one

Desktop visualizers need installs, drivers and codecs. BLOOB runs on WebGL and Canvas in Chrome, Edge, Safari and Firefox, on Mac, Windows, Linux, iPad and Android. Your audio is analysed on your own device with the Web Audio API — nothing is uploaded, which also means there is no queue and no processing limit.

What makes the visuals actually follow the music

BLOOB separates the kick, snare, hats, risers and drops with a dedicated onset analyser, then predicts the beat grid a few milliseconds ahead so visuals land on the beat instead of after it. Every scene binds its geometry to specific bands: bass drives size and gravity, hats drive sparkle, drops trigger scene changes.

Export without a watermark

Recording captures the canvas at 1080p, 2K or 4K in MP4 or WebM, with social aspect ratios (9:16, 1:1, 16:9). The offline exporter renders frame by frame, so even a slow laptop produces a smooth 60 fps file.

How to do it
