Frequently asked questions
- Is this music visualizer really free?
- Yes. The core visualizer runs in your browser at no cost. We may show ads on content pages after cookie consent.
- Do you upload my audio?
- No. Microphone and uploaded files are analysed locally in the browser for visualization.
- Which browsers work?
- Recent Chrome, Edge, Firefox, and Safari on HTTPS. Mic access may require a secure context.
- Can I use it offline?
- You need to load the site once online; after that, cached assets may work in some setups, but mic and media APIs expect a normal HTTPS session.
