Audio Visualizer
Turn any audio into a shareable video — bars, circle or waveform reacting to the sound, with cover art, a title and your background — rendered on your device.
How to Use Audio Visualizer in 3 Steps
Drop the audio
MP3, WAV, M4A, OGG or FLAC — a song, podcast clip or voice note up to 10 minutes. A still preview of the layout appears on the right.
Design the frame
Add cover art, a title and subtitle, pick a style (circle, bars, mirror, wave, dots), the video size for your platform, colours and a background.
Render and download
Click Render video. It records in real time with the audio, so keep the tab open; then download the MP4/WebM or copy a frame as PNG.
Audio Visualizer — Frequently Asked Questions
Is my audio uploaded anywhere?
No. The file is decoded by your browser's Web Audio engine, processed on your device and encoded in the page. Nothing is sent to a server.
Why does rendering take as long as the track?
The browser plays the audio through an analyser and records the canvas with MediaRecorder in real time — a 3-minute song takes 3 minutes. Keep the tab visible; background tabs throttle the frame timer.
Which format do I get?
MP4 (H.264 + AAC) in Chrome and Edge on most systems; WebM (VP9/Opus) in Firefox or where MP4 recording is unavailable. Both upload fine to YouTube, Instagram and TikTok.
How do I make a Reel or Short?
Pick Vertical 1080 × 1920. The cover sits in the upper third and the title underneath, which is the layout Reels and Shorts crop for.
Is there a length limit?
Ten minutes. Longer audio would mean a very large file and a very long real-time render — split it with the Audio Splitter first.
Can I use my own font or logo?
Text uses the system UI font so it renders identically everywhere. For a logo, bake it into the background image or the cover art.
