Frame
Records in real time, at the shape and resolution above. No watermark, no sign-up, no upload — the file is made in your browser.
- Nothing is uploaded Your audio is decoded and drawn by your own browser.
- No watermark The export carries nothing but your video.

A finished video, in the shape you are posting it
Pick the frame first — Reels and Shorts are vertical, YouTube is wide — and the visualiser draws and records at that size rather than cropping a widescreen canvas afterwards.
The frame you are actually posting
Choose 9:16, 1:1, 4:5 or 16:9 before you record, and the canvas is drawn at that shape and resolution. Nothing is cropped afterwards, so a vertical video is composed vertically rather than being a widescreen one with the sides cut off.
-
Ten styles, nine colourways
Frequency bars, spectrum, mirrored bars, waveform, circular wave, concentric rings, radial bars, particles, light beams and a flow field — each in nine palettes, switchable while the track plays.
-
No watermark, no account
The file you download is the file you made. Nothing is stamped on it, nothing is gated behind a sign-up, and there is no export limit.
-
A title burned into the video
Type the track and artist and it is drawn into the frame, scaled to the size you are exporting, so the video reads on its own in a feed.
-
Nothing is uploaded
Your audio is decoded and analysed by your own browser. It is never sent anywhere, which is also why it starts instantly instead of waiting on a queue.
-
Bands spaced the way you hear
The analyser's output is folded into logarithmic bands before it is drawn, so bass does not crush the left edge and the top octaves are not a flat line.
-
Works on a phone
No install, no plug-in. Recording needs a desktop browser, but the visualiser itself runs anywhere modern.
Four steps to a file
-
Add your track
Drag an audio file in, or pick one — MP3, WAV, OGG, M4A or FLAC up to 70 MB. It is decoded in your browser; nothing is uploaded.
-
Choose the frame
Vertical for Reels, Shorts and TikTok, square or 4:5 for a feed, widescreen for YouTube. Pick 720p or 1080p.
-
Pick a look
Ten styles and nine palettes, plus an optional title drawn into the video. Change any of it while the track plays.
-
Record and download
Press record and the track plays through once, captured in real time at the size you chose. The file downloads straight from your browser, with no watermark.
Looking for something different?
This turns audio you already have into a video. If what you want is the sound itself, or the notes behind it, start somewhere else.
-
You want to hear a MIDI file, not watch it
MIDI-to-audio renders any MIDI file with real instruments and exports MP3, WAV or OGG.
-
You want the notes out of a recording
The audio-to-MIDI converter transcribes a track into a MIDI file you can edit.
-
You want to play the piece yourself
The sheet music library has the score, and the virtual piano plays along with it.
How the picture follows the sound
A Web Audio analyser, folded into bands the way hearing is spaced, drawn on a canvas your browser then records.
Rendering
Every style is drawn on an HTML5 canvas sized to the export frame, so the preview on screen and the recorded file are the same pixels. Motion is driven by requestAnimationFrame and follows the audio clock, not a fixed timer.
Audio analysis
A Web Audio AnalyserNode runs a 2048-point FFT. The bins are folded into 64 logarithmically spaced bands — because an FFT is linear in frequency and hearing is not — then smoothed with a fast attack and a slow release so a kick lands on the beat and decays instead of flickering. There is no machine learning involved; it is signal processing.

Privacy
The audio file is read with File.arrayBuffer() and decoded locally. It is never sent to a server — there is no upload endpoint — and the recording is assembled by MediaRecorder in the same tab. Closing the page discards everything.
Frequently asked
What is a music visualizer?
A music visualizer is a tool that creates animated visuals synchronized with your audio track. It transforms the sounds, beats, and rhythms into dynamic animations, providing an engaging visual experience that complements your music.
Do I need any special software or skills to use the audio visualizer?
No special software or technical expertise is required. Our online tool is designed to be user-friendly and accessible from any modern web browser.
Can I use the sound visualizer on my mobile device?
Yes, our music visualizer is fully compatible with mobile devices. You can create and edit videos directly from your smartphone or tablet.
What audio and video formats are supported by the audio spectrum?
We support all major audio formats, including MP3 and WAV. The rendered videos are exported in MP4 format, which is widely compatible with various platforms and software.
How long does it take to render a video audio visualization?
There is no render queue and no server — the video is captured in real time while the track plays, so a three-minute song takes three minutes. The file is ready the moment playback ends.
Do I need a powerful computer to render audio to visual?
No — the drawing is done by your browser's graphics stack, and it is light work: a laptop or a mid-range phone handles the preview comfortably. Recording is more demanding than previewing, so a desktop browser gives the steadiest frame rate on a long track, but nothing is rendered on a server, which also means nothing to queue for.
Can I upload my music visualization directly to social media platforms?
After downloading your video, you can upload it to any social media platform. Our videos are optimized for platforms like YouTube, Instagram, TikTok, Facebook, and more.
Is there a limit to the number of video music visuals I can create for free?
No. With our service, you can create an unlimited number of videos for free. There are no restrictions on your creativity.
What are the output video music visualizers resolutions and quality?
Up to 1080p on the short edge: 1920×1080 widescreen, 1080×1920 vertical, 1080×1080 square or 1080×1350 for a feed, with a 720p option for smaller files. Capture runs at 30 frames per second in real time, at 5–12 Mbps depending on the frame size.
Is there any cost to use the music visualizer?
No. Our visualizer is completely free to use, with no hidden costs or subscriptions.
Can I use the videos for commercial purposes?
Yes, you have full rights to use the videos you create for commercial purposes, such as marketing, promotions, and monetized content.
How is my audio data used and stored?
We do not store any of your audio files on our servers. Your audio files are used solely in the browser to create your visualizer videos. We just make use of local storage to save your custom created schemes directly in your browser. We respect your privacy and do not share your files. You can delete your uploaded files from your account at any time.
Why should I choose your video visualizer over other music visualizers online?
Because it gives you the frame you are actually posting — vertical, square or widescreen, composed at that shape rather than cropped afterwards — and hands back a file with no watermark, no account and no export limit. It also never uploads your audio, so it starts instantly.
Do you offer support if I need help?
Yes, we have a contact us page that you can use to get in touch with our support team. But the tool its so easy to use that you most likely won't need any help.
Are there any limitations on the length of the audio track or music visualized?
Our platform supports audio tracks of various lengths. For extremely long tracks, rendering times may increase. And the current maximum audio file size that we support is 70MB
Do you offer templates for different music genres in your online visualizer?
Not genre templates, no. There are ten visual styles and nine colourways, which combine into ninety looks, plus an optional title drawn into the video. You can change any of them while the track is playing and watch the result before you record.
Is my content secure on your audio spectrum maker platform?
We prioritize your privacy and security. And as said before, your content is not stored on our servers.
