Frequently Asked Questions
Is my audio recorded?
No. The microphone input is processed entirely in your browser using the Web Audio API. No audio is recorded, stored, or transmitted anywhere.
The bar isn't moving — what should I do?
Check that your microphone is set as the default input device in your OS settings. Make sure the browser has microphone permission (look for a mic icon in your browser's address bar). Try speaking louder or moving closer to the mic.
