Audio Visualizer
Turn a track into a video you can post. Free, no watermark, no upload.
Your file never leaves your browser — the visual is rendered and recorded on your device.

How to make an audio visualizer
To make an audio visualizer, choose an audio file above, pick a style and a colour scheme, and press Record. The tool reads the track's frequencies as it plays and draws them to a canvas, then captures that canvas together with the audio into a video file you can download. It is free, needs no account, adds no watermark, and nothing is uploaded — the whole thing runs on your device, so it works offline once the page has loaded. One thing to know before you start: recording happens in real time, because the browser captures the animation as it plays. A three-minute song takes three minutes, and the tab has to stay open and visible while it does.
What the three styles are actually showing
Bars is a spectrum. The horizontal axis is frequency — bass on the left, treble on the right — and each bar's height is how much energy the track currently carries at that frequency. It is the most informative of the three: you can see a kick drum hit the left-hand bars and a hi-hat light up the right.
Waveform is the signal itself, drawn as it moves — amplitude over time rather than frequency. It reacts to loudness rather than to pitch, which makes it calmer and better suited to material without a strong beat.
Radial is the same spectrum as Bars, wrapped into a circle. It carries the same information and reads better in a square or vertical crop, which is why it tends to suit Instagram and TikTok posts.
All three deliberately ignore the top of the frequency range. An analyser reports evenly up to half the sample rate, so on a normal file the upper half of the spectrum covers 11–22kHz — where recorded music has almost nothing. Drawing it would waste most of the width on a flat line and make a loud track look dead.
Visualizer or music video?
Worth being straight about, since this is our tool and we sell the other thing.
A visualizer is the right choice when you need something up quickly and the music is the point: a release-day YouTube upload so the track has somewhere to live, a Spotify Canvas loop, a snippet for stories, a lyric-free post for an instrumental. It costs nothing, takes minutes, and nobody expects it to be more than it is.
It is the wrong choice when you want people to share it. A visualizer reacts to sound; it does not show anything. There is no scene, no character, nothing to describe to someone else. That ceiling is inherent — a nicer palette does not raise it.
Most artists end up wanting both, and in that order: a visualizer on release day because it is ready now, and a real video when the track earns one.
Frequently asked questions
How do I make an audio visualizer video?
Load your track, choose one of the three styles and a colour scheme, then press Record. The tool plays the song, draws the frequencies to a canvas as it goes, and captures both into a video file. When the track ends, a download button appears. No account and no watermark.
Is it free? Is there a watermark?
Free, unlimited, no account, and no watermark on the output. The rendering happens in your browser rather than on a server we pay for, which is why it can stay open rather than metered or branded.
Why does recording take as long as the song?
Because the browser captures the animation as it plays — there is no way to fast-forward a live canvas capture. Rendering faster than real time would need the video to be encoded offline rather than recorded, which browsers do not offer without shipping a full encoder into the page. We would rather be honest about the wait than pretend it away.
Does my music get uploaded?
No. Your browser decodes and analyses the file on your device, and the recording is assembled locally too. You can verify it by watching the network tab, or by disconnecting from the internet after the page loads — it still works.
What video format do I get?
WebM in most browsers, which YouTube, Instagram and TikTok all accept on upload. If you need MP4 for a specific editor, any free converter will remux it without re-encoding the picture.
Which browsers work?
Chrome and Firefox handle the recording reliably. Safari's MediaRecorder support is patchy and may fail on the export even though the live visual plays fine — the tool says so rather than producing a broken file.
What is the difference between a visualizer and a music video?
A visualizer reacts to the audio itself — bars, waveforms and shapes driven by the sound, with no filmed or generated footage. A music video tells or shows something: scenes, characters, a place. Visualizers are quick and cheap and work well for a release-day upload or a Canvas loop; a music video is what people actually watch and share. They serve different jobs and most artists end up wanting both.
Want the version people actually share?
Attach a track and describe what you want in one message. An AI director storyboards it scene by scene, with the same character in every shot. Your first project's keyframes are free, so you see the whole storyboard before deciding to render.
