Are my recordings uploaded?

No. Audio is captured and processed entirely in your browser using the Web Audio API and MediaRecorder. Nothing leaves your device.

What formats can I download?

WebM (Opus codec) by default for smallest size, or MP3 (192 kbps) for universal compatibility — converted on-device with ffmpeg.wasm.

Yes. Pause stops appending data without ending the recording; Resume continues into the same file.

Toggle the noise suppression option, check OS microphone gain, and avoid covering the mic. The live waveform shows real-time input level.

Safari on iOS supports MediaRecorder since iOS 14.5. Some older iPad versions may fall back to MP4 audio container.

No hard limit, but very long recordings consume browser memory. Keep under 60 minutes for best reliability.
