Frequently asked questions
Do I need to install anything to record audio in the browser?
No. The recorder uses the browser MediaRecorder API. Allow microphone access when prompted and you can start immediately.
Is my recorded audio uploaded anywhere?
No. Capture, playback, and download all stay on your device. Sessions are kept in memory and are lost if you close the page.
What format does the recording download in?
WebM (Opus) in browsers that support it. Safari may download M4A instead. Convert later if you need MP3 or WAV.
Why is the browser asking for microphone permission?
The page cannot hear your mic until you allow it. Permission stays in the browser; Utilvia never receives the stream.
Is audio recorder free?
Yes. It runs in your browser with no signup. Recordings stay on your device until you download them.
