or tap the mic icon to go live — click anywhere to browse a file
Drop in an MP3, WAV, or M4A file, or tap the microphone icon to visualize sound from your mic in real time instead.
PULSE analyzes the audio's frequencies as it plays and drives the visuals directly from that — the movement is genuinely tied to what's playing, not a looping animation.
Cycle through color themes on the fly to match the mood of what's playing, or just to find the look you like best.
PULSE is built to be watched, not exported — leave it running as ambience, a second-screen visual, or background for something else you're doing.
Visualize an uploaded track, or switch to live mic input to react to sound happening in the room right now.
The movement is generated directly from the audio's actual frequency data as it plays, not a pre-made animation loop.
Cycle between color themes to change the visual mood without changing anything about the audio itself.
No controls or clutter over the visual itself — just the reactive display, ready to use as ambience or a second-screen accompaniment.
Yes. PULSE is free to use, supported by ads rather than a subscription or paywall. There's no sign-up required.
No. PULSE runs entirely in your web browser — there's nothing to download or install, and it works on Windows, Mac, and Linux.
Yes — tap the export icon to record what's playing as an MP4, downloadable when it finishes. It starts and stops with the track automatically when a file is loaded, or you can stop it manually while using live mic input. The video editor also has this exact visualizer built in as one of its layer styles, if you'd rather sync it into a larger project.
Yes — the style icon cycles between Reactor Core (the original pulsing centre with a ring of bars), Bars (a classic horizontal equalizer with a reflection), and Orbit (three independent rings, one per bass, mid, and treble). All three react to the exact same audio analysis, just drawn very differently, and switching mid-track doesn't interrupt playback.
Common formats like MP3, WAV, and M4A all work, or you can skip a file entirely and use live microphone input instead.
No. All audio processing and rendering happens locally in your browser — your file or microphone audio is never uploaded to a server.
