Privacy: microphone samples are processed in this browser. Recording downloads stay on your device unless you share them. Sound levels are in dBFS (digital signal level), not calibrated dB SPL or a hearing-safety measurement. AI labels are estimates, not proof of a source. The AI model is downloaded from an external host when requested.
