How to make a music visualizer, start to finish

The whole process on one page: get the sound in, choose a scene that matches the song, set the frame and export a clean MP4. No editor, no plugins, no subscription, about five minutes.

Who this is for

1. Get the sound in

An audio file is the best source, because the whole track is analysed before the first frame is drawn: tempo, beat grid, quiet and peak sections and drops. A microphone, an instrument through an interface or a shared browser tab all work for live sources, but they have no lookahead, so the auto-director reacts rather than anticipates.

2. Choose a scene that matches the song

Match the movement, not the mood board. Heavy low end suits Liquid BLOOB or Arc Storm; busy hats suit Pulse Lanes; sparse or ambient material suits Aurora or Nebula. Then set a mood (Chill, Signature or Hype) and a palette, and let the auto-director change scenes on section boundaries instead of on a timer.

3. Frame it and export it

Pick the aspect — 16:9 for YouTube, 9:16 for Shorts, Reels and TikTok, 1:1 for feed posts, or the 8-second Spotify Canvas loop — add a title if the platform needs one, then export offline for a frame-perfect file. Record live instead if you want to perform the scene changes yourself.

How to do it

  1. Open BLOOB and load your audio file
  2. Pick a scene with ← →, then a mood and palette that fit the track
  3. Set the aspect ratio and resolution in the Export group
  4. Export MP4 — rendered offline, frame by frame, with no watermark

Questions people ask about how to make a music visualizer

Do I need video software?

No. Everything happens in the browser and what comes out is an ordinary MP4 or WebM you can upload anywhere.

How long does it take?

Offline export usually runs faster than real time: a four-minute song takes one to two minutes on a typical laptop.

Can I add lyrics or captions?

Yes — load an .lrc or .srt, tap-sync them by hand, or transcribe the track locally with Whisper.

Can I do a whole album at once?

Yes. Batch export takes several files and renders a full-song MP4 for each, one after another.
