Microphone recording on mobile
This mobile version records microphone audio only. For screen recording or shared/system audio, use a compatible desktop browser.
Audio is temporarily saved in this browser. Export each completed segment using Download or Share → Save to Files. Clearing site data or private browsing can remove recordings.
Keep this page visible and your device awake. Switching apps or locking the screen triggers a stop attempt, but may interrupt saving. Export promptly; browser storage is not a backup.
Desktop recording
Audio only creates an audio file without a recorded video track. If shared audio is enabled, the browser still needs a display-source picker, which may display a sharing indicator. The display video is not added to the recorded stream.
How to use it
- Choose Audio only. Enable Microphone, Shared audio, or both.
- Choose the folder and start. Approve microphone access and any shared source requested by the browser.
- Check the actual audio-source status. Record a short spoken sentence and play the saved file before starting a long take.
Limits and safety
When no live audio track is granted, recording does not start. Two sources are mixed with Web Audio gain reduction; this is not a guarantee against clipping or echo. This app does not output the mix to speakers.

A practical test
For a voice note, say a quiet sentence followed by a louder one and listen back using headphones. A live microphone permission is not proof of a useful level or a clean environment. On mobile, complete and export the test before relying on a longer take. A file still held in browser storage is not the same as an exported backup.
