Browser-local audio visualizer
Choose an input, style, colors, sensitivity, and frame. Export support depends on your browser; the page explains the limitation before you render.
Choose the demo, microphone, or an audio file.
Local processing: this tool does not upload the selected audio or artwork.
Useful controls
Switch bars, waveform, or radial mode and tune colors, sensitivity, and aspect ratio.
Honest export
WebM works best in Chromium and Firefox; unsupported combinations keep a clear fallback.
How to create an audio visualizer
Choose an input
Use the demo, allow microphone access, or select an audio file from this device.
Pick the response
Bars emphasize frequency bands, waveform shows amplitude over time, and radial mode centers the motion.
Tune the frame
Set colors, sensitivity, and a 16:9, 9:16, or 1:1 canvas for the publishing surface.
Preview and export
Watch the full track, then export WebM in a supported browser or use a screen-record fallback.
Visualizer styles compared
| Style | Best for | Control tip |
|---|---|---|
| Frequency bars | Beats, electronic music, and clear rhythm | Increase sensitivity carefully to avoid constant clipping |
| Waveform | Speech, podcasts, and a clean soundwave | Use a contrasting line on a simple background |
| Radial | Album artwork and social music posts | Use square art and leave breathing room around the center |
| Microphone preview | Live sound, voice, instruments, and testing | Permission is temporary and can be stopped at any time |
Browser and export limitations
The visualizer is real, but media APIs vary across browsers and devices.
- Safari may not include audio in MediaRecorder exports; use Chrome, Edge, or Firefox when export matters.
- Keep the page open while exporting the full track.
- Large lossless files and high-resolution canvases use more memory and CPU.
- Microphone input requires explicit browser permission and is not recorded unless you start an export.
Audio visualizer FAQ
Does this audio visualizer upload my file?
No. The interactive tool processes the selected file in your browser. The page does not send the audio to a Vidloop API.
Can I use a microphone?
Yes, in a browser that supports getUserMedia. You must grant permission and can stop the stream from the tool or browser.
Which audio files work?
Common browser-supported formats such as MP3, WAV, AAC, M4A, OGG, and WebM audio usually work; codec support depends on the browser.
Why is export unavailable?
Your browser may not support canvas capture, MediaRecorder, or audio-track recording in the requested combination. Use a current Chromium or Firefox browser or screen-record the preview.
