1. What does this tool do
This free online sound recorder records audio from your microphone in one click—no app, no sign-up. Use it as a voice recorder or audio recorder in the browser for voice memos, quick notes, or any time you need a local recorder. Allow microphone access, start and stop recording, then download the file. All processing runs in your browser so your recordings never leave your device. Ideal for voice memos, voice messages, interviews, or audio notes.
2. How to use it
Quick start: Click to enable your microphone, click "Start recording" to begin, click "Stop" when done, then hover over the recording and click the download icon to save it. Remove recordings with the X button to free memory.
- Allow access — Click the button to enable your microphone.
- Start recording — Click "Start recording" to begin capturing audio.
- Stop recording — Click "Stop" when done. The recording is added to the list.
- Download — Hover over any recording and click the download icon to save it.
- Remove — Hover and click the remove (X) button to discard a recording and free memory.
3. How it works
The tool uses the browser's MediaDevices API (getUserMedia) to access the microphone. Audio is recorded with the MediaRecorder API, which produces WebM (or MP4 on Safari) chunks; these are combined into a single Blob and offered for download. All recordings are kept in browser memory as blob URLs until you remove them or leave the page. HTTPS is required because getUserMedia only works in secure contexts. All processing runs in your browser. No data is sent to any server.
4. Use cases & examples
- Voice memos — Record quick notes or reminders without a separate app.
- Voice messages — Record a short audio message for sharing.
- Interviews — Capture an interview or conversation for later.
- Audio notes — Record ideas or dictation when typing is inconvenient.
5. Limitations & known constraints
- HTTPS required — The tool does not work on plain HTTP (except localhost).
- Browser support — getUserMedia and MediaRecorder are supported in all modern browsers; older browsers may not work.
- Format varies — Output is typically WebM (Opus) or MP4/M4A on Safari. Some players may need conversion.
- Permissions — You must grant microphone access. Denying blocks the tool.
