About Voice Recorder
Voice Recorder records your microphone with the MediaRecorder built into the browser. "Pause" and "Resume" continue the same recording; "Stop recording" ends it. The file comes in the format your browser records: M4A (AAC) where it can record MP4 audio, as Safari and Chrome or Edge 126 and later do, and WebM (Opus) elsewhere, such as Firefox. "Export as MP3" makes a 192 kbps MP3 with ffmpeg.wasm, and "Export as WAV" a 16-bit WAV. Nothing is recorded until you allow the microphone.

Where your recording is processed
The microphone sound is recorded by your browser and stays on this page. The MP3 export uses ffmpeg.wasm, downloaded from unpkg.com, and the WAV export the Web Audio API, both on your device. No recording is sent to a server. If the microphone cannot start or an export fails, that message, cleaned, reaches our error log with your browser's name and version.
Frequently asked questions
Is the recording an MP3?
No, not directly: it is saved in the format your browser records, M4A (AAC) or WebM (Opus), and the extension always matches the content. Click "Export as MP3" for a 192 kbps MP3, or "Export as WAV" for an uncompressed WAV.
Can I pause and continue the same recording?
Yes. "Pause" holds the recording and "Resume" carries on in the same file; only "Stop recording" finishes it. Starting a new recording replaces the previous one, so download it first.
Can I record if I blocked the microphone?
No. The page shows "Microphone access was refused" until you allow the microphone for this site in your browser settings. A device without a microphone gets "No microphone was found on this device."
Is there a time limit?
No. The page sets no maximum length; the recording grows in the memory of your browser until you click "Stop recording", so very long sessions depend on your device.
