- Speak normally while the local audio analyzer measures level and peak activity.
- Optionally make a short local recording or run the guided quality check.
What this result cannot prove
- Measurements describe the stream delivered to this browser, not the microphone hardware in every app.
- Approximate dBFS, noise, and clipping indicators are diagnostic hints rather than laboratory measurements.
