Check microphone input with a live waveform and relative peak and RMS levels, without speaker monitoring.
Ready. Start explicitly to begin.
Start requests microphone permission. Speak normally and inspect the waveform and level meter. There is no live speaker monitoring. For a playback sample use our Audio Recorder.
Microphone access is requested only on Start, on HTTPS or localhost, with browser permission. Only audio is requested. The waveform and peak/RMS measurements are relative digital full scale (dBFS), not sound-pressure level, hearing or calibrated loudness tests. No speaker monitoring, recording or upload occurs. Stop, hidden tab, switching or page exit releases tracks and audio context. Delivered browser processing settings may differ from requested settings.
Reports contain the observations currently shown, not an automatic hardware health verdict. No report is uploaded or saved automatically.
These tools run locally and do not upload your device observations, camera video, microphone input or interaction events. There are no accounts or stored test histories. Camera and microphone access stays under browser permission controls.

No. The browser exposes a limited set of events and reported settings. Inspect or listen to the actual result and compare with other applications if needed. Missing browser events or unavailable features do not prove a hardware failure.
Active input capture, audio playback and camera/microphone tracks are released on Stop, hidden tab, workspace switching and page exit. Pending permission results are ignored and late tracks stopped. Reports download only when explicitly chosen.
