Audio visualizer for Reels

Leave the sound
as a star chart.

Drop in a track and get a vertical video for Reels. While the dial makes one turn, the sound settles like stars. Angle is time, radius is frequency. PRO adds loudness, key and BPM along the bottom.

FAQ
Questions
What does it run on?
Tested on Google Chrome for macOS and on iPhone (Safari, iOS 17 or later). Export records while playing, so keep the tab open and in front during export. On iPhone, MP3 / M4A files are lighter than WAV for long tracks.
Which files can I load?
WAV / AIFF / MP3 / M4A. Drop the file onto the page.
Can I use the exported video commercially?
Yes. There is no watermark, free or paid.
Is my audio uploaded?
No. Analysis through export runs entirely in your browser.
Is it a subscription?
No. $10 once, nothing after.
Why do the meters disappear from the free export?
Exporting the meters is a PRO feature. The free version shows them on screen so you can check first.
